Giovanni di Agostino

Introduction: The Historiographical Problem

Few artists of the Sienese Trecento illustrate as vividly as Giovanni di Agostino the distance that can separate a documented historical figure from the figure constructed by later tradition. On the one hand stands a man attested by a short but reliable chain of archival records running from 1331 to 1347: the son of a sculptor, trained in his father’s workshop, active in Arezzo in his youth, and then, still remarkably young, entrusted with the direction of the most ambitious building enterprise Siena ever attempted, the colossal extension of the cathedral known as the Duomo Nuovo. On the other hand stands the artist of the later literature, a figure who for centuries simply did not exist. Giorgio Vasari¹, whose Lives shaped the memory of Tuscan art for three hundred years, never names him. Whatever Giovanni made was absorbed into the fame of his father, Agostino di Giovanni, or rather into the fame of the composite creature Vasari invented, the heroic pair of “Agostino et Agnolo scultori et architetti sanesi.” The recovery of Giovanni di Agostino as a distinct historical and artistic personality is therefore one of the more instructive stories in the historiography of Italian Gothic sculpture, and any responsible account of him must begin by acknowledging how little is fixed and how much remains contested.

The fixed points are, in truth, astonishingly few. A single work bears his signature: the small marble relief of the Madonna and Child enthroned between two angels in the Oratorio di San Bernardino in Siena, inscribed “Ioh(anne)s magist(r)i Agostini de Se(n)is me fecit,” that is, “Giovanni, son of master Agostino of Siena, made me.” A single documented ensemble contracted directly with him survives: the Tarlati chapel of 1334 in Arezzo Cathedral. Around these two anchors, and around the archival record of his career as capomaestro of the Opera del Duomo of Siena, the modern critical tradition has built a catalogue whose every other item is attribution, and whose most beautiful items are precisely the most disputed, contested between Giovanni and his own father with arguments of equal seriousness on both sides. Much of what circulates about him online, moreover, is demonstrably wrong, from the claim that he carved the Tarlati tomb of 1330 to the notion that he lived until about 1370.

This essay attempts to set out what can responsibly be said about Giovanni di Agostino on the basis of primary and secondary sources alone. Throughout, four levels of evidence are kept deliberately distinct: what period documents actually record; what a signature or inscription securely establishes; what constitutes broadly accepted attribution; and what remains hypothesis or open scholarly debate. Where the sources disagree among themselves, the disagreement is recorded rather than silently resolved, and where a commonly repeated claim finds no support in the evidence, it is explicitly identified as an error to be retired.

The critical literature on Giovanni is substantial and, in its recent phase, highly technical. The articles of Werner Cohn-Goerke of 1938 and 1939, one of them published under Giovanni’s name in The Burlington Magazine, first isolated Giovanni as a distinct artist with a coherent catalogue. The studies of Roberto Bartalini from the mid-1980s onwards — an essay of 1986 on the novelty of Giovanni’s “pictorial” relief, a set of “five postscripts” in 1994, the entry in the Enciclopedia dell’Arte Medievale of 1995, a chapter in the 2011 survey of Sienese Gothic sculpture, and a monograph of 2019 on the Duomo Nuovo — offer the fullest and most sustained reconstruction of the artist. The entry of Gert Kreytenberg in the Dizionario Biografico degli Italiani of 2001, together with a series of articles from 1990 onwards, presents the most systematic alternative reading, one that transfers a significant part of the traditional corpus from the son back to the father. Other contributions, from the eighteenth-century antiquarians to the most recent journal articles, are named only where they bear on a specific point. Vasari himself is treated throughout as what he is: an early source of great historiographical interest, to be read critically, not as a modern authority.

Vasari’s “Agostino et Agnolo” and Its Deconstruction

Any history of Giovanni’s reputation must begin, paradoxically, with a text that never mentions him. In the 1568 edition of the Lives, Vasari opened his biography of the two Sienese masters with a genealogy of civic virtue: “Fra gl’altri che nella scuola di Giovanni e Nicola scultori pisani si esercitarono, Agostino et Agnolo scultori sanesi, de’ quali al presente scriviamo la vita, riuscirono secondo que’ tempi eccellentissimi” — among those who trained in the school of Giovanni and Nicola, the Pisan sculptors, Agostino and Agnolo, Sienese sculptors, whose life we now write, turned out most excellent for those times. Their ancestors, Vasari continued, had themselves been architects, who in 1190, “sotto il reggimento de’ tre Consoli,” completed Fontebranda and, the following year, the city’s Dogana. The narrative then unfolds with Vasari’s characteristic assurance. Giovanni Pisano, returning from Naples to Pisa in 1284, stopped in Siena to design and found the cathedral façade, and Agostino, “non avendo più che quindici anni” — being no more than fifteen years old — joined him to study sculpture, soon outstripping his fellow pupils “in disegno, grazia e maniera” and earning the epithet “l’occhio diritto del suo maestro,” the right eye of his master. Agostino in turn brought “Agnolo suo fratello minore,” his supposed younger brother, into the profession.

To this pair Vasari assigned an imposing series of works and buildings: the palace of the Nove in Malborghetto of 1308, the north façade of the Duomo of 1317, the Porta Romana begun in 1321 and finished in 1326 together with the rebuilding of the Porta a Tufi, the church and convent of San Francesco in Siena, prophets for the façade of Orvieto Cathedral, a marble altarpiece for San Francesco in Bologna dated 1329, the conduit that brought water to the fountain of the Campo, which “cominciò a gettare l’anno 1343 a dì primo di giugno,” and the completion of the tower of the Palazzo Pubblico in 1344.

The keystone of the whole construction is the Tarlati tomb in Arezzo. Vasari relates that Giotto, passing through Orvieto on his way to Naples in 1326, admired above all “i profeti d’Agostino e d’Agnolo sanesi,” befriended the two sculptors, and recommended them to Piero Saccone da Pietramala for the tomb of Bishop Guido Tarlati², which they then executed “in quel modo però che egli l’aveva disegnata, e secondo il modello che esso aveva al detto Piero Saccone mandato” — exactly as Giotto had designed it, and according to the model Giotto had sent to Piero Saccone. Vasari even quotes the tomb’s inscription, in the form “Hoc opus fecit magister Augustinus et magister Angelus de Senis.” The Life closes with Agostino’s death: while Agnolo was at work in the Lower Church at Assisi, Agostino, “che a Siena era rimaso per servigio del publico, si morì mentre andava facendo il disegno degl’ornamenti della detta fonte di piazza, e fu in Duomo orrevolmente sepellito” — he who had remained in Siena in the public service died while designing the ornaments of the fountain of the piazza, and was honourably buried in the Duomo. Of Agnolo, Vasari candidly admits, “Non ho già trovato… nè come nè quando morisse.”

Documentary research has dismantled almost every structural element of this narrative. Agnolo di Ventura was not Agostino’s brother at all but his professional partner; the encyclopedic literature states explicitly that Vasari “erroneamente” believed them to be kin. The chronology of the apprenticeship is impossible: Agostino is first documented at his marriage to Lagina di Nese on 11 September 1310, and modern scholars accordingly place his birth around 1285, which rules out a fifteen-year-old pupil at Giovanni Pisano’s side in 1284.

The Dizionario Biografico entry on Agostino dismisses Vasari’s account as “ampie, ma inattendibili notizie,” extensive but unreliable information, while the Enciclopedia dell’Arte Medievale observes that Vasari’s attributions, “specie quelle riguardanti le imprese architettoniche di A. e Agnolo, non hanno per massima parte ricevuto convalida negli studi moderni” — especially those concerning the architectural enterprises of the pair, they have for the most part not been confirmed by modern studies. Giotto’s supposed design for the Tarlati tomb is now treated as a Vasarian commonplace, driven by the biographer’s wish to bind Sienese achievement to the Florentine tradition; recent scholarship states flatly that the idea “è da respingere,” it is to be rejected. Even the internal logic of the Life falters: Vasari places the Bologna altarpiece of 1329 “dopo” a tomb that is itself dated 1330, and he speaks of “dodici storie” on that tomb where there are in fact sixteen reliefs.

The tomb’s inscription itself is transmitted in more than one form. Where Vasari gives the singular “fecit,” the Dizionario Biografico entry on Agostino gives “Hoc opus fecerunt magister Augustinus et magister Angelus de Senis MCCCXXX” — Master Agostino and Master Agnolo of Siena made this work, 1330 — while the Enciclopedia dell’Arte Medievale prints “Hoc opu(s) fecit magiste(r) Augustinu(s) (et) magiste(r) Angelu(s) de Sen(is) MCCCXXX.” Whether the verb on the stone is singular or plural cannot be settled without direct examination, and this essay leaves the question open; what is beyond doubt is the date, 1330, and the presence of two names, neither of which is Giovanni’s.

Vasari’s silence about Giovanni is itself historically significant. In the passages of the Life consulted for this study, every “Giovanni” who appears is Giovanni Pisano; no son of Agostino is ever mentioned. The documented partnership of father and son, which runs continuously from 1331 into the 1340s, was simply invisible to the Vasarian tradition, and everything the two men made together could only be credited to the heroic pair “Agostino e Agnolo.” Recovering Giovanni has therefore required two successive operations of criticism: first, the Vasarian pair had to be broken apart into two distinct, documented masters, Agostino di Giovanni and Agnolo di Ventura; and then a third personality, the son, had to be extracted from within the father’s own workshop. The first operation was largely the work of the nineteenth-century document publications; the second remains, as will be seen, unfinished to this day.

Family and Workshop: The House of Agostino di Giovanni

The documentary evidence on Giovanni’s family is sparse but unambiguous in its essentials. Agostino di Giovanni, himself the son of a master Giovanni, married Lagina di Nese on 11 September 1310. From this marriage came two sons, Giovanni and Domenico, both of whom became sculptors and architects. The encyclopedic literature dates Giovanni’s birth “poco dopo il 1310,” shortly after 1310, or more cautiously “dopo il settembre del 1310,” after September 1310 — an inference drawn from the marriage document, which was published in the great late-nineteenth-century collections of Sienese archival material. It must be stressed that no birth record survives: the conventional “c. 1310” found in catalogues is an earliest possible date derived from the parents’ wedding, not a documented fact. Domenico, the younger son, first appears in the records in a land sale of 26 November 1343, and a series of sales and purchases of houses and land from 1343 onwards shows the family living in Siena, in the parish district, the popolo, of San Quirico.

Agostino’s own career forms the frame within which Giovanni was trained, and its outline can be traced document by document. In 1329 the Comune of Siena paid him ten soldi³ for carrying a letter to Pier Saccone Tarlati in Arezzo, a mission the literature plausibly connects with the negotiation of the commission for the Tarlati tomb. In 1330 he signed that tomb together with Agnolo di Ventura. In 1331 he was at work on the vaults of the Palazzo Comunale in Siena; in 1336 on the fortress of Massa Marittima; in 1339 he held the civic office of Operaio della Torre del Comune. In 1340 he undertook, with other masters, to bring water to the Fonte del Campo, and on 4 February of that year, in partnership with Agostino di Rosso and Cecco di Casino, he contracted to build the street façade of Palazzo Sansedoni. By 27 June 1347 he was dead: a sale document of that date describes his son as “Johannes olim Magri Agostini,” Giovanni, son of the late master Agostino. A secondary source, an online compilation citing the archive of the Spedale di Santa Maria della Scala, reports a final notice of Agostino alive on 24 January 1346, a payment made in his name on his son’s behalf to the hospital; the notice is plausible but has not been independently verified for this essay, and it is offered here with that caveat.

What matters for the study of Giovanni is that the relationship between father and son was contractual and artistic as well as familial. The most important document of Giovanni’s entire career, the contract of 23 March 1340 by which he became capomaestro of the Opera del Duomo for five years, records that Agostino gave his explicit consent to the appointment and promised his son advice and help. The Dizionario Biografico draws the inescapable conclusion: “Anche se la documentazione superstite è insufficiente, rimane chiaro che l’attività artistica di G. fu, per tutta la sua vita, legata a quella del padre Agostino” — even if the surviving documentation is insufficient, it remains clear that Giovanni’s artistic activity was, for his whole life, bound to that of his father. Father and son worked on the same sites, under the same contracts, with the same assistants, sharing materials, models and no doubt hands within single monuments. That intimacy is precisely what makes the attribution of individual works so intractable: the corpus of the family workshop is well defined, but the internal boundary between Agostino and Giovanni shifts with every generation of scholarship.

Domenico’s later career lies largely outside the scope of this essay, though it should be noted that he went on to direct work on the cathedral after the Duomo Nuovo project was abandoned in 1357, and that his own catalogue has been assembled around works described in the encyclopedic literature as “dipendenti dallo stile del padre e legate in maniera sorprendente a quello del fratello Giovanni” — dependent on the father’s style and surprisingly bound to that of his brother Giovanni. The family, in other words, dominated the Sienese cathedral workshop across the middle decades of the century, and the problem of distinguishing its members from one another does not end with Giovanni’s death.

The Documented Biography: An Archival Chain from 1331 to 1347

Because the documents on Giovanni are few, it is worth following them in order, noting where the sources disagree. The account rests principally on the entries in the Dizionario Biografico degli Italiani and the Enciclopedia dell’Arte Medievale, which in turn depend on the nineteenth-century Sienese document publications and on subsequent archival research.

The chain opens on 31 March 1331, when Giovanni and his father received a payment from the priest Goro for work on his chapel in the Pieve di Santa Maria in Arezzo — a chapel that appears to have taken the form of an altar with a canopy set against a wall of the church, and that is now destroyed. Less than a year later, on 7 February 1332, Simone and Iacopo Ghini contracted with Agostino for a second chapel in the same Pieve, on the express condition that Giovanni work on it as collaborator; on 13 February and again on 15 August of that year Giovanni appears in connection with the Ghini chapel acting as his father’s legal agent, his procurator. That a patron should stipulate the participation of a man who can hardly have been more than twenty-one years old is itself eloquent testimony to the reputation the young sculptor had already acquired. The decisive step came on 28 January 1334, when Roberto Tarlati contracted with Giovanni — with Giovanni directly, no longer through his father — for a chapel in Arezzo Cathedral, to be modelled on the Ghini chapel and erected in memory of Ciuto Tarlati. This chapel survives intact, and it is the only commission documented as contracted with Giovanni himself whose work can still be seen.

It should be recorded that the dates of the Arezzo chapels are not transmitted uniformly. The older Dizionario Biografico entry on Agostino speaks of a payment “il 10 marzo 1332” to Agostino and his son Giovanni for the Ghini chapel, and adds that on “7 febbr. 1333” another chapel in the same Pieve was assigned to them; the later entries follow the contract date of 7 February 1332 for the Ghini chapel. The sources consulted for this essay do not reconcile the reading that places the Ghini contract on 7 February 1332 with the reading that places the assignment of a further chapel on 7 February 1333, and rather than choose silently between them, both are recorded here. One popular online biography garbles the 1334 record altogether, claiming that on 28 January 1334 “i lavori alla cappella furono saldati,” the works on the chapel were settled, and connecting the date to the Ghini chapel, whereas the authoritative entry gives that date for the Tarlati contract.

By November 1336 Giovanni had moved to a position of an entirely different order: he is documented as capomaestro of the Opera del Duomo of Siena, the master of the cathedral works. He still held the post in March 1337, when the Opera of Orvieto Cathedral paid him for his journey there and for a stay of eight days, and in August of the same year, still described as Sienese capomaestro, he travelled with an Orvietan colleague to Pisa to order Carrara marble for Orvieto, in the documentary formula transmitted by the encyclopedic literature “pro facto marmi pro Ecclesie Sancte Marie.” On 3 December 1339 a payment from the Comune of Siena shows that Giovanni, like his father, had worked on the aqueduct that fed the Fonte del Campo. Then, on 23 March 1340, came the great contract: Giovanni was engaged as capomaestro of the Opera for five years, with his father’s approval, through what the Opera’s own historical account describes as an administrative deed signed by the Operaio Latino de’ Rossi.

On 26 April 1341 the Hospital of Santa Maria della Scala paid him for the tombstone of messer Buonconte and for a tomb of Saint James, San Giacomo; both works are lost. Land sales by Agostino and his sons are recorded on 26 November 1343 and 21 February 1344. Payments from the Opera del Duomo to Giovanni as capomaestro continue from June to November 1344 and from May to June 1345. Finally, on 27 June 1347, Giovanni witnessed the sale of a house — the same document in which his father is already described as “olim,” deceased — and the Enciclopedia dell’Arte Medievale notes that he was “ancora nel 1347… documentato in stretto rapporto con l’Opera del duomo,” still in 1347 documented in close relation with the cathedral workshop.

After that date the archive falls silent, and everything said about Giovanni’s end is inference. Both principal encyclopedic entries hedge carefully: one states that he “morì verosimilmente nel 1348 durante la peste di Siena,” died in all likelihood in 1348 during the Sienese plague; the other that the works stopped in 1348 “dopo la grande pestilenza in cui probabilmente anche G. morì,” after the great pestilence in which probably Giovanni too died; and the Opera itself writes that he drove the Duomo Nuovo forward until his death in 1348, “when he was probably carried off by the plague.” Those hedging adverbs deserve to be taken seriously. The literature consulted cites no death record, no will, no obituary; the date 1348 is inferred from the abrupt end of the records and from the demographic catastrophe of that year. The correct formulation, pedantic though it may sound, is that Giovanni is last documented on 27 June 1347 and probably died in 1348 — not that his death in 1348 is a documented fact.

Two widespread biographical errors must be corrected here. The first concerns Orvieto. One online biography of Agostino asserts that in 1337 Giovanni “viene nominato capomaestro dell’Opera del Duomo” at Orvieto, “succedendo alla dinastia dei Maitani,” succeeding the Maitani dynasty; even an authoritative encyclopedia entry on Agostino states that in 1340 the father “permetteva al figlio di assumere la carica di capomastro del duomo di Orvieto,” allowed his son to take up the office of capomaestro of Orvieto Cathedral.

The documents summarized in the entries on Giovanni himself contradict both claims: they show him at Orvieto in 1337 as a visiting Sienese capomaestro, paid for his travel and a short stay, and they place the appointment of 1340 unambiguously in Siena. Giovanni was capomaestro of Siena, never of Orvieto. The second error concerns the transition of 1340. Lando di Pietro, the goldsmith and engineer summoned from the Neapolitan court of Robert of Anjou⁴ in December 1339 to direct the cathedral extension, died on 3 August 1340; Giovanni’s contract is dated 23 March 1340. Popular accounts that have Giovanni simply “succeeding” Lando in March compress the sequence. The Opera’s own account explains that for some months the two men worked side by side, Lando as a kind of overseer paid in part by the Comune, Giovanni as the Opera’s own master builder — a division of roles more revealing of the project’s institutional complexity than any tidy succession would be.

The Arezzo Years and the Tarlati Patronage

Giovanni’s training is nowhere documented. The Dizionario Biografico reasonably proposes that he served his apprenticeship as stonecutter and sculptor in his father’s workshop from about 1325 to 1328, and that he then took part in the carving of the Tarlati tomb. It is at this point that the question of his earliest hand begins, and it is here above all that the levels of evidence must be kept scrupulously apart.

The Tarlati monument itself is secure at the level of documentation and epigraphy. It is signed and dated 1330 by Agostino di Giovanni and Agnolo di Ventura, and it was commissioned by the brothers of Bishop Guido Tarlati, the lord-bishop of Arezzo who had died in 1327. A great tabernacle with a pointed gable rises over a space that is now empty; beneath it lies the funerary chamber, with the bishop lying in state and angels drawing back curtains; and beneath the chamber run sixteen narrative reliefs in four rows, separated by statuettes of the bishop, all of which were beheaded in 1341 when Pier Saccone and the Pietramala were driven out of Arezzo. The inscriptions in the frames name the subjects of the reliefs — “Il Comune pelato,” “Comme in Signoria,” “El Fare de le Mura,” “Castei Focognano,” “Rondine,” “Bucine,” “Caprese,” “La morte di Misere” and the rest — though these captions were probably redone at the end of the eighteenth century. According to the Dizionario Biografico, the monument was moved in 1783 from the chapel of the Sacrament to its present position near the sacristy door; some popular descriptions give 1788 instead, a discrepancy noted here without being resolved.

Giovanni’s participation in this monument, by contrast, is not documented at all: it is an attribution founded entirely on style. Cohn-Goerke, in 1938, was the first to attempt a separation of hands among the reliefs, isolating two masters and assigning to Agostino the sculptures of the funerary chamber, the panels numbered 1, 2, 3, 4, 13, 14, 15 and 16, and parts of panels 6 and 11. Kreytenberg went further in 1990, proposing that Giovanni carved part of the left-hand relief with the funeral rites and, among the narrative scenes, “Il Comune pelato,” the “Comune in signoria,” “Castel Focognano,” “Rondine,” “Bucine” and “Caprese.” These reconstructions are serious and plausible, but they remain reconstructions: in a joint monument signed by at least two masters and executed with an unknown number of assistants, any division of hands is conjecture, and the Enciclopedia dell’Arte Medievale adds a further complication by observing that both of Agostino’s sons may have taken part.

Against this background, the most widespread error in the popular literature must be stated plainly. The English-language Wikipedia article on Giovanni asserts that “He sculpted a monument to Bishop Guido Tarlati in 1330,” and a derived chronological list repeats the claim; one popular Italian source states that the tomb was commissioned “a Agnolo di Ventura e Giovanni di Agostino”; and even an encyclopedic entry on Arezzo describes the cenotaph as “firmato e datato (1330) da Giovanni di Agostino e Agnolo di Ventura,” signed and dated by Giovanni di Agostino and Agnolo di Ventura. The inscription itself disproves all of these formulations: it names “magister Augustinus” and “magister Angelus,” Agostino and Agnolo, not Giovanni. At most, Giovanni was a young assistant within his father’s workshop, and the assignment of specific panels to him is hypothesis, not fact.

The two Pieve chapels of 1331 and 1332 are documented but destroyed, and it is around them that one of the most interesting reconstructive efforts of the twentieth century took shape. For the Ghini chapel the contract survives with detailed specifications, and on that basis a study of the mid-twentieth century linked three surviving marbles to its decoration: an Angel of the Annunciation in the Victoria and Albert Museum in London, a Virgin Annunciate in the Louvre, and a fragmentary relief bust of an angel in the Szépművészeti Múzeum in Budapest. The Louvre Virgin, inventoried as CAMP 5 A, has a traceable history: it was in the Ottavio Gigli collection, where it is attested in 1858, and in the Campana collection it formed part of a composite altarpiece assembled from unrelated pieces. According to the Louvre’s own record it was paired with the London angel as early as 1922 and later identified with the group “qui ornait les pinacles du tabernacle de la chapelle Ghini, commandé le 7 février 1332 à Giovanni d’Agostino pour la Pieve di Santa Maria d’Arezzo” — the group that adorned the pinnacles of the tabernacle of the Ghini chapel, commissioned on 7 February 1332 from Giovanni d’Agostino for the Pieve of Arezzo.

The museum catalogues it as marble with traces of polychromy, 0.73 metres high, 0.21 metres wide and 0.175 metres deep, and dates it broadly “vers 1330 – 1348.” The V&A angel, accession number A.25-1938, stands 77 centimetres high and is dated by the museum “ca. 1333-34”; it is described as “considerably worn and chipped,” with the right arm broken and repaired, and the museum’s summary still repeats an older observation that the figure “appears to be closely related to a group of sculptures which originally appeared over the doorway of the Bishop’s Palace at Volterra.” The Budapest fragment, in Bartalini’s reading, may come from the gable relief of the chapel, its tympanum. A study published in 2019 in the Bollettino d’arte returned to the whole ensemble under a title quoting the contract’s own words, «Uno mezzo Salvatore de marmo bello et grande et ben fatto» — a half-length Saviour of marble, beautiful and large and well made — and devoted itself to “gli esordi di Giovanni d’Agostino nella cappella Ghini,” Giovanni’s beginnings in the Ghini chapel. The association of these three scattered marbles with the destroyed chapel is thus a well-supported and widely accepted hypothesis, grounded in the contract and in style; it is not a documented provenance, and the museums themselves signal as much with their cautious wording.

To the same Arezzo years belongs, by broadly accepted attribution, the sculptural decoration of the baptismal font of the Pieve di Santa Maria, whose reliefs show three scenes from the life of John the Baptist: the young John led into the desert, the “Ecce Agnus Dei,” and the Baptism of Christ. Cohn-Goerke assigned these reliefs to Giovanni in 1938, and both principal encyclopedic entries accept the attribution.

The Tarlati chapel of 1334 in the Cathedral is the first genuinely secure reference point for Giovanni’s personal style. Its evidentiary status is twofold: the commission is documented by contract, while the assignment of its sculpture to Giovanni’s own hand rests on the reasonable but unprovable inference that a contract concluded with the son means that the son carved its figures. Architecture, sculpture and frescoes are examined in the section on the chapel below.

Where the Record Begins: The Arezzo Font and the Birth of a Style

The work on which the whole critical argument has leaned from the beginning is the baptismal font of the Pieve di Santa Maria in Arezzo, whose three marble panels are the foundation of the case for Giovanni di Agostino’s “pictorial” relief. The font stands free on its stepped base against the pieve’s ochre ashlar, a broad six-sided chest of stone with the white marble stories glowing in its faces — an object at once monumental and domestic, the parish’s oldest piece of working furniture. One point of address must be settled at the threshold: the font belongs to the pieve, as the Dizionario Biografico states and the image confirms, and not to the cathedral of Arezzo, where a strand of the online literature — the Italian Wikipedia included — mistakenly houses it; the reader who goes looking should go to Santa Maria.

Arezzo, and this building in particular, is where Giovanni’s documented life begins, and the font sits at the centre of that beginning. The sculptor’s first surviving document is the payment of 31 March 1331 for the chapel of the priest Goro in this very pieve; in 1332 father and son built the Ghini chapel here, of which three sculptures survive — the Virgin now in the Louvre and the angels of London and Budapest, treated below; and at the same time, the Dizionario’s reconstruction continues, Giovanni must have executed the pieve’s baptismal font with its three stories of the Baptist. The date of about 1332 that follows makes the font exactly contemporary with the Ghini marbles and a near neighbour of the Volterra shrine of Kreytenberg’s c. 1331 — the tight cluster of years in which, on the accepted reconstruction, the twenty-year-old’s manner first declared itself.

The object as it stands is a composite of marble and building stone. The chest is hexagonal, closed by a plain moulded cornice above and a stepped plinth below, its top now fitted with the metal plates and ring of a modern cover; into the three faces this viewpoint discloses are set the three marble panels, each sunk within a simple raised frame, their white and lightly veined stone standing out against the warm beige of the chest. Whether that structure is the original Trecento carcass or a later remounting of the three reliefs is not stated in the sources consulted, and the question is left open here; what is secure is that the three figured panels are the attributed core, and that the faces continuing round the back escape both this image and, apparently, the iconographic record.

The central panel is the Baptism of Christ, and it is carved as a gathering rather than a duet. Christ stands at the centre, frontal, his hand drawn to his breast in the gesture of acceptance, his legs sunk in the Jordan’s wavy, heaped water; the Baptist steps in from the left, his arm extended to lay the baptizing hand on Christ’s head; at the far left an angel bends inward over its burden, and at the right two more figures attend, the nearer angel stretching out a hand with the garment held ready — the extended arm undercut clean of the ground, the panel’s boldest passage of salience. Rocky banks close the lower corners and climb the right edge, so that the sacrament happens inside a landscape rather than before a backdrop; and the relief itself performs the doctrine of the “pictorial” relief, projection graduated from the near angel’s free-floating hand back through Christ’s mid-salience to the attendants sinking toward the plane.

The flanking panels — read here at an oblique angle, with the caution that implies — carry the cycle’s rarer episodes. On the left face, the young John is sent into the desert: an angel flies across the upper register while below, among rocks, the small figure of the child Baptist is conducted into the wilderness that will make him — a subject drawn from the legendary infancy of the saint, seldom carved, and chosen, one suspects, precisely because it is a story of terrain. On the right face, the Ecce Agnus Dei: a compact crowd of standing figures, disciples and listeners pressed shoulder to shoulder, turned toward the pointing Baptist at the panel’s left edge, nearest the Baptism as he identifies the Lamb — the cycle’s scene of speech, as the desert panel is its scene of landscape and the Baptism its scene of action.

The selection itself deserves a paragraph, because it is eccentric and eloquent. A Baptist cycle on a font ordinarily opens in the household — the annunciation to Zacharias, the birth, the naming; this one skips the domestic chapters entirely and gives its three faces to the wilderness, the proclamation and the river: John made by the desert, John announcing, John baptizing. It is a program about vocation rather than biography, and it plays to the medium’s strength as this sculptor understood it. Rocky grounds, heaped water, figures emerging from and receding into an uneven terrain are exactly what the graduated, atmospheric relief does best; the panels read as three exercises in making marble behave like a painted ground — the “rilievo pittorico” for which the Arezzo font, with the slightly later Volterra reliefs, supplies the critical literature from Kreytenberg to Bartalini with its founding evidence, and against which the elder Agostino’s manner of discrete volumes on a flat ground stands as the family’s other pole.

Within the corpus the font is a hub with spokes in every direction. It shares its site and its moment with the Ghini fragments — the same campaign in the same building, c. 1331–32, sculptor’s debut and dispersal’s survivors; and it opens the corpus’s Baptist line, continued by the Cleveland panel and closed by the Montepulciano font of the late 1330s, so that Giovanni carved the sacrament’s own furniture at both ends of his decade — Arezzo a chest of narrative panels at floor level, Montepulciano a chalice on Apostle shoulders.

A note on condition and caveats follows. The marble is veined and worn, with surface losses softening the flanking panels especially; the modern cover plates interrupt the top; the relationship of panels to chest, the state of the rear faces, and the object’s dimensions are unverified in the sources consulted; and the attribution, secure in the specialist literature, remains stylistic, anchored to the documents of the Goro and Ghini campaigns rather than to a contract of its own. None of this touches the font’s standing. Here, in the building where his name first enters the record, the young sculptor was given the parish’s water to frame — and answered with a desert, a sermon and a river, carved in the graduated, breathing relief that the rest of the corpus has traced outward from these three faces ever since.

A Grove, a Hill, an Order: Giovanni di Agostino’s Desert Panel at Arezzo

The first of the Arezzo panels to be read at close range is the cycle’s opening scene, and the close view immediately earns its keep: what the oblique glance across the whole font suggested as two angels leading a child by the hand resolves, face on, into something rarer and finer — a single angel in full horizontal flight, streaming across the upper register, arms thrust forward to point the way, while below and apart the young Baptist climbs toward the wilderness on his own feet, hands joined in prayer. The correction matters iconographically. John is not led into the desert; he is sent — commanded from the air and obeying from the ground — and the entire panel is built on the space that the command must cross.

The subject descends from the thinnest of scriptural threads and the thickest of legendary ones. Luke says only that the child “grew, and waxed strong in spirit, and was in the deserts till the day of his shewing unto Israel”; the apocryphal lives of the Baptist, and after them the Tuscan Trecento, filled that verse with the departure scene — the boy leaving the world for the wilderness, sometimes guided, here dispatched by angelic order. The sculptor has made the proleptic choice of dressing him already in the camel-hair tunic, corded at the waist: the hermit’s uniform donned at the moment of vocation, so that the garment itself announces the destination. On a font, the scene carries the program’s first lesson — that the sacrament administered in this basin begins with a call and an assent — and it opens the triptych of desert, proclamation and river that the whole font describes.

Compositionally the panel is an X drawn in air. The angel’s flight-line runs a long descending diagonal from the upper left corner toward the treetops at the right; the Baptist’s body and gaze run the answering diagonal, rising from lower left toward the messenger; the two vectors cross above the panel’s centre — which the sculptor has left magnificently empty. Bare, smoothly swelling ground occupies the middle of the field, nothing but polished marble between the boy and the grove: the desert itself, given the courage of blankness at the heart of a crowded medium. Around that void the panel distributes its three densities — feathered angel, pelted saint, leaved grove — like instruments around a rest.

The angel is one of the great flying figures of Trecento sculpture, and the enlargements let its machinery be admired. The body is a single streamlined diagonal, the tunic wound tight by the airflow into long bias folds, the gown’s trailing end snapping into a swallow-tail behind; the raised wing spreads its anatomy in ordered courses — imbricated coverts scaling the shoulder, long primaries stacked in parallel slats — while the hair is combed back from the brow in fine wind-drawn striations. Both arms drive forward together, hands open toward the grove: the gesture is not greeting but direction, an order with a bearing. And the figure performs the panel’s boldest formal act: its streaming drapery breaks the frame, the trailing point lapping over the inner fascia at the left edge — the messenger arriving from beyond the picture’s world, heaven entering the field from outside its borders. One further delicacy rewards patience: the swallow-tail’s lower tip dips to graze the Baptist’s upturned brow, so that command and called almost touch — the order transmitted, as it were, along the hem.

The Baptist below is all assent. He strides up the slope on bare feet, body in profile, and his head is thrown back so steeply that the face is carved in upward foreshortening — chin’s underside, cheek and lifted eye — a daring piece of drawing in stone for the early 1330s. The hands are joined palm to palm beside his face, fingertips up: prayer as acceptance, the visual “fiat” answering the angel’s imperative. He is young, curly-headed, beardless as far as the surface permits judgment; and his tunic is the panel’s tour de force of texture, the camel pelt rendered as an all-over field of tufted, flame-like locks, each tuft cut and polished so the shag glints — the same problem of sacred animal hide that the Cleveland Baptist solves with punched pellets, here answered with the chisel’s tongue-shaped bites.

The right half belongs to the landscape, and to the sculptor’s evident delight in it. On a hill of smooth, undulating, almost liquid rock stands a grove of trees with sinuous, bending trunks and dense crowns — and the crowns are built exactly as the wing is built, of overlapping fan-clusters of individually cut leaves, layered like feathers; between the clusters run vertical rows of drilled holes, the running drill punching shadow-dots into the foliage precisely as it dots the beard of the Volterra gisant. Wing, pelt and leafage thus declare themselves one family of textures from one workshop’s tool-kit, disposed against the bare polish of hill and sky; and the grove itself — trees carved with a botanist’s patience, given a third of the field — is landscape promoted from prop to protagonist, as advanced a commitment to setting as Tuscan marble relief of the date has to show.

The panel gathers threads from across the corpus. The flying angel is the elder sibling of the airborne bearers of the Magdalene gable in Siena; the combed parallel hair belongs to the same graphic system as the Magdalene’s waves; and the graduated carving — the angel’s arm and the near leaf-fans undercut free, the hill sinking to a breath of relief — is the “rilievo pittorico” at its most programmatic, on the very object the critical literature has always named as its cradle. If the c. 1332 dating holds, this panel and the Volterra shrine stand within a year of each other: the same young hand, sending one saint into the desert and laying another in state.

A note on condition and caveats follows. A crack crosses the top rail above the wing; surfaces are worn and the marble veined, with the frame’s fascia abraded; the Baptist’s facial detail is softened; no dimensions for the panel are published in the sources consulted; and the attribution, as for the font entire, is stylistic. What needs no document is the panel’s idea. A command crosses empty air; a boy answers with joined hands and keeps walking; and the desert that will make him waits at the right — carved, by a sculptor barely out of his father’s shadow, as the most inviting wilderness in Tuscan stone.

Among You Stands One: Giovanni di Agostino’s Scene of Testimony at Arezzo

The second panel to be read at close range is the cycle’s scene of speech: the Ecce Agnus Dei, the Baptist pointing out Christ. Its place on the font is the right-hand face, and the installed sequence — desert on the left, Baptism at the centre, this testimony on the right — turns out to follow the Gospel of John’s own order, where the pointing happens on the day after the Baptism: “Behold the Lamb of God.” Read around the chest, then, the three panels narrate exactly as the fourth evangelist does — the making of the prophet, the sacrament at the river, the announcement to the world — and this panel carries the cycle’s conclusion: the moment the Baptist’s whole career funnels into a single extended arm.

The subject’s theology is deixis itself. John’s office, in the fourth Gospel, is not to baptize but to testify — to be “the voice,” the finger that indicates — and the sculptor has taken the pointing gesture as the panel’s entire engine. Everything in the field either points, relays a pointing, or is pointed at; the composition is a diagram of testimony in transit. And it opens with a spatial statement of the Baptist’s biography: he stands at the left in front of the grove — the same trees, leaf-fan crowns and bending trunks, that filled the desert panel, so that the wilderness of the first scene continues around the font’s corner into this one — the man of the desert addressing the world from the treeline, one foot still in the landscape that made him.

The grove itself deserves its sentence, because the sculptor has turned botanist. The tree behind the Baptist’s shoulder bears small oval leaves on thin sprays, olive-like; the tree into which his arm extends carries long feathered fronds, palm-like; a bare sapling rises between. Two species distinguished within a single panel — variety of foliage as deliberate as the variety of faces opposite — and the graduated relief treats them accordingly, the near fronds undercut, the far sprays sinking toward the plane.

The Baptist is the adult of the type the corpus knows: long-haired, bearded, sheathed in the tufted camel pelt whose flame-locks here run down the raised arm itself, the prophet’s uniform continued to the wrist. He stands in profile, head bowed slightly toward his audience, and his right arm extends level at shoulder height across the field — the hand, worn where it crosses the palm fronds, overlapping the tree’s crown in a frank piece of spatial layering, gesture passing in front of landscape. The arm is the panel’s horizon: everything below it presses and murmurs, everything above it is halo and leafage.

The crowd is a masterpiece of differentiated attention, seven figures deep in two ranks, and it can be inventoried as one inventories the poor of Volterra and the students of Pistoia. In the front rank, at the left, a man in a close cap performs the panel’s wittiest invention — his index finger extended in a pointing of his own, aimed at his neighbour, a bearded man in a lappeted hood who holds a book against his chest and lifts a worried, heavy-lidded face — the announcement relayed as gesture inside the crowd, testimony propagating like a wave.

At the right edge stand the finest pair: a man seen entirely from behind, his wavy hair combed down his back in careful parallel strands, face lifted toward the haloed figures; and, pressed against him, a small hooded elder — an aged woman, to judge by the wrap and the sunken little face — her hand laid on his shoulder, steadying herself to see or urging him to look. The back-turned man is the composition’s repoussoir and its ethics: he stands where the viewer stands, facing into the panel, our delegate inside the crowd.

And the crowd contains its secret. At the rear rise three haloed heads: a disciple, a young long-haired companion — and between them Christ, long hair parted at the centre, short bipartite beard, his incised halo worn smooth of any cross it may have carried. He alone, in a panel of turned and craning heads, gazes directly out of the relief at the viewer. The device closes the circuit the whole field has been wiring: the Baptist points at Christ; the capped man relays the pointing; the back-turned man looks where we cannot; and Christ, the object of every gesture, looks past them all at us — “among you standeth one, whom ye know not” carved literally, the Lamb embedded and half-unrecognized in the crowd until the panel’s deixis discharges into the beholder’s own eyes. On a baptismal font, before which every christening party stood, the address could not be plainer: the pointing ends at the person holding the child.

Stylistically the panel is the crowd movement of the pictorial relief, and it invites comparison with the crowds of Volterra and Pistoia. Its press of overlapped bodies, projection graduated from the high-carved front rank to the rear heads flattening against the ground, is the same idiom as the Volterra Distribution of a year or so earlier — the same taxonomy of headgear and age, the same refusal to repeat a face — and stands at the opposite pole from the elder Agostino’s Cino relief of the later 1330s, where a crowd is an alignment of discrete volumes on an abstract plane. Here the ground itself participates: smooth rising terrain underfoot, the grove’s layered depths at the left, air implied above the heads. If the desert panel is the cycle’s landscape and the Baptism its action, this is its polyphony — many attentions orchestrated around one finger.

A note on condition and caveats follows. The Baptist’s pointing hand is abraded where it meets the foliage; surfaces are worn throughout, with the marble’s violet veining surfacing across the drapery; the upper background is roughened; halo incisions survive only faintly; no dimensions for the panel are published in the sources consulted; and the attribution, as for the font entire, is stylistic. What the wear cannot blunt is the panel’s intelligence about its own medium. Testimony, John’s sacrament, is made of direction — and direction is the one thing relief sculpture commands absolutely. A finger, a relayed finger, a turned back, a frontal gaze: with four vectors the young sculptor built a machine that has been pointing out the Lamb, to everyone who stands where the back-turned man stands, for seven hundred years.

The Rite Facing the Rite: Giovanni di Agostino’s Baptism of Christ

The central panel completes the Arezzo triad, and it is the one whose self-reflexivity is absolute: a Baptism of Christ carved on the front face of a baptismal font — the rite’s own image mounted on the rite’s own furniture, facing the priest at the very moment he repeats what it depicts. Every baptism performed at this basin has been performed in front of this panel; the christening party stood where the viewer stands, the water moved a hand’s breadth from its carved archetype. Of the three scenes this is the cycle’s action, flanked by the desert’s landscape and the testimony’s speech, and the sculptor has met the responsibility of the position with his stillest, gravest composition.

The iconographic choices are precise and, on a font, pointed. The Baptist does not pour from a bowl or shell: he lays his hand flat upon Christ’s head — the ancient imposition formula that belongs to baptism by immersion, which is exactly the rite this chest-like font was built to administer; image and use agree down to the gesture. The Jordan is the old conventional mound, water heaped bell-like around Christ to the waist as though the river had gathered itself to receive him — the visual echo of the Psalm’s Jordan that “was driven back.” And the angels hold the garments, the motif of Byzantine descent that the Trecento kept: heaven as Christ’s valet, dignity waiting on the bank. Five figures in all, the cast that a view of the whole font counts from a distance, now legible one by one.

The composition breathes inward. At the left a single angel bows deeply from the hips, its whole back rounded into a curve of reverence; at the right two angels lean in together; between the two bows Christ rises vertical and the Baptist’s arm bridges the interval — a symmetry animated, never frozen, in the manner of the Volterra angels. The flanking bends are differentiated exactly as the Volterra curtain-angels and the commendation pair were differentiated: one attendant solitary and profound in its bow, clasping a small draped bundle — Christ’s folded clothing, or hands veiled in a cloth — against its waist; opposite, a sociable pair, the nearer angel extending both arms with the great drape hung ready across them. Behind all the heads runs a low horizontal ledge, the far bank of the river reduced to a single step of ground: landscape as stage-edge, the minimum that will hold the scene in a place.

Christ is the panel’s plumb-line. He stands frontal in the mound, nude to the water, torso softly modelled, his right hand raised flat against his breast in acceptance; the face — long parted hair, moustache and short beard with its small chin-tuft — is grave, the eyes open and lowered toward the beholder’s side of the river. And down that torso runs the detail that alone would justify the close-up: from the sternum a thin carved rivulet descends the midline of the belly and gathers, just above the navel, into a hanging teardrop — a drop of the baptismal water itself, caught mid-run on the skin. The invention is the more brilliant for its context, because the sculptor has polished the Jordan almost perfectly smooth, a still swelling mass with barely a ripple: the whole river holds its breath, and the panel’s entire quantity of motion is concentrated into one drop the size of a fingertip. Beside Christ’s flank a slender banded rod descends into the water — a reed of the Jordan, or the shaft of the Baptist’s cross-staff, the wear leaving the alternative open — and is noted here without being forced.

The Baptist is the man the two flanking panels have made. The camel pelt, tufted in the same flame-locks that clothed the boy of the desert scene and the pointing prophet of the Ecce, hangs from his shoulder as he leans out over the water; his profile bows toward Christ; his bare toes grip the very edge of the bank, curled over the rock above the river — a small marvel of observed balance, the prophet at the physical limit of the dry land his whole biography has occupied. The hand on Christ’s crown is carved with the fingers spread flat through the hair: not ceremony at arm’s length but contact, pressure, the sacrament as touch — of a family with the panel’s other minute contacts, the drop on the skin, and, across the cycle, the angel’s hem grazing the boy’s brow.

The angels repay the enlargements. The left one, its shoulder streaked by the marble’s dark veining, folds forward over its bundle with a curly cap of hair and the corpus’s soft oval face; its wing displays the full anatomy of coverts and primaries. The nearer right angel wears on its chest a small cross-hatched square — an embroidered tablion, the same taste for ornamented dress as the speaking angel of Volterra — and its hand emerges beneath the hanging drape, fingers delicately pinching the cloth’s edge; its companion’s face has suffered the panel’s one grave wound, a loss shearing the features. And at the far right margin, beyond the angels, the background carries the panel’s quietest radicalism: vegetation rendered by incision alone, a shrub merely engraved on the flat ground — the furthest register of the projection scale, relief graduated all the way down to drawing, distance expressed as the vanishing of salience itself. It is the “rilievo pittorico” pushed to its logical horizon.

Within the corpus the panel closes more than the triad. It is the second of Giovanni’s two carved Baptisms of Christ, and the pair is thus complete: at Montepulciano, at the decade’s end, the Baptist administers the water in the pouring arc above a striated mound; here, at its beginning, he lays the hand of immersion on a river polished still — one subject, one hand, two modes and two waters, the liturgical spectrum of the sacrament covered between two Tuscan towns. The Baptist himself, with Cleveland, now appears five times across the accepted corpus; and the drop on Christ’s skin takes its place in the poetics of the corpus — the pinched hem of a vanished curtain, a crone’s hand on a shoulder, a drapery-tip grazing a boy’s brow: a sculptor whose theology lives in the smallest possible contacts.

A note on condition and caveats closes the triad. The companion angel’s face is sheared; dark veins and stains cross the left angel’s shoulder; surfaces are worn, any halo incisions on Christ now barely legible; the identity of the banded rod is unresolved; no dimensions are published in the sources consulted; and the attribution, as throughout, is stylistic. Taken together, the three Arezzo panels — desert, river, testimony — let the font’s argument be heard whole: that the water in this basin descends from that water; that the hand the priest lays on the child repeats that hand; and that of all the ways marble can be made to speak of baptism, none says more than a single carved drop, forever halfway down the breastbone of Christ.

The Signed Relief in San Bernardino

The single work that bears Giovanni’s name is also the only item in the entire corpus that belongs to the second of our evidentiary categories, the works established by signature. Together with the Tarlati chapel it became the foundation of the twentieth-century image of Giovanni; whether that image holds depends, as will emerge, on which works one is prepared to admit into the corpus, and the comparison with the Cleveland relief, discussed below, turns precisely on this signed piece.

Madonna and Child Enthroned between Two Angels

In the vestibule of the upper oratory of the Compagnia di San Bernardino in Siena, within the complex that now also houses the Museo Diocesano d’Arte Sacra, hangs the one work in the entire corpus of Giovanni di Agostino that speaks his name. The relief occupies a unique evidentiary position: everything else associated with this sculptor — the Tarlati chapel figures in Arezzo, the Ghini fragments dispersed between Paris, London and Budapest, the contested marbles of Volterra and Cleveland, the sculpture of the Duomo Nuovo — is either documented by contract or assigned by attribution, and the attributions, as the critical literature shows, oscillate perpetually between Giovanni and his father Agostino di Giovanni. Here alone the stone itself testifies. Along the lower edge of the frame, in Gothic majuscules punctuated by interpuncts, runs the inscription that the Enciclopedia dell’Arte Medievale transcribes as “Ioh(anne)s magist(r)i Agostini de Se(n)is me fecit”: Giovanni, son of master Agostino of Siena, made me. For every discussion of this artist’s hand, this modest marble is the touchstone against which all else is measured.

The inscription deserves to be read as attentively as the carving above it. It employs the ancient “speaking object” formula, “me fecit,” by which the work declares its own authorship in the first person, and it identifies the maker not by his own title but through his father’s: Giovanni is “son of master Agostino,” his identity professionally anchored in the paternal name even at the moment of asserting his independence from it. In a workshop whose entire production would be credited for centuries to the father — Vasari never names Giovanni at all — the signature performs a double gesture, at once filial and self-affirming. The letters visible in the image, with their abbreviation strokes and the compressed “SE(N)IS,” correspond closely to the transcription of the scholarly literature, and their placement on the projecting lower border, directly beneath the Virgin’s footrest, makes the declaration of authorship literally the foundation on which the sacred image stands.

The composition is of studied simplicity. A rectangular field is enclosed by a carved frame whose inner face is worked with running foliate ornament and rosettes; at the top, the sculptor has carved a baldachin of stone drapery, a canopy whose fringed cloth is gathered and looped as though drawn up over the scene, so that the frame itself becomes an architecture of honour, a portable ciborium in miniature. Beneath this canopy the Virgin sits frontally enthroned at the centre, the Child supported on her left side, while two standing angels flank the throne in three-quarter turn, their wings rising against the lateral borders and their bodies inclining gently inward. The ground between the figures now reads as a deep blue that sets off the pale marble with almost pictorial force; whether this colouring preserves original polychromy or represents a later intervention is not stated in the sources consulted, and the question is best left open, though the effect as it stands — carved figures against a flat field of colour — vividly suggests the dialogue between sculpture and panel painting that the critical tradition has placed at the heart of Giovanni’s art.

The Virgin herself is conceived with the elongated elegance that the literature associates with this master. Her oval face, framed by a close-fitting veil, is carved with the small mouth, narrow almond eyes and high smooth brow of the Sienese ideal; her glance does not meet the viewer but passes slightly aside, absorbed and grave. Her mantle falls from the head in long unbroken curves, opens over the breast, and then cascades across her knees in a sequence of deep, softly hollowed folds whose hems are finished with carved fringes — borders that retain darkened traces of what appears to be pigment or gilding, minute survivals of a once richer chromatic dress.

The throne has almost disappeared beneath this textile abundance: only the base beneath her feet remains legible as architecture, so that the Virgin seems seated upon drapery itself, a mass of falling cloth that the sculptor manipulates with evident delight. The Child, held against her left side, is a compact, vigorously modelled figure who turns outward toward the beholder, one hand raised; the Virgin’s right hand rests at her breast in a gesture of tender presentation. The intimacy of the pair, combined with the ceremonial frontality of the whole, holds devotion and majesty in a single image.

The two angels translate the theme of homage into courtly attendance. The angel at the left carries a vessel from which rises a carved bouquet — the flowers, worked almost in the round, now darkened with age — presenting it toward the Virgin like an offering at a throne; the companion at the right holds a smaller object, its surface now abraded, in hands drawn close to the breast. Both figures stand in a gentle contrapposto, their weight shifting beneath long tunics whose diagonal mantle-folds answer the cascades of the Virgin’s own drapery, and their heads, with loosely waving hair, incline toward the centre with expressions of the same grave sweetness as hers. They are not the massive, block-like attendants of the older Sienese sculptural tradition but slender, mobile presences, conceived as if a painted angelic court had been translated into shallow marble.

It is precisely this quality that made the relief central to the modern critical image of Giovanni. The Enciclopedia dell’Arte Medievale condenses that image into a famous formula: Giovanni as the “alter ego in scultura di Simone Martini,” the sculptural counterpart of Simone, who, freed from the “cubizing” plasticism of his father Agostino, pursued “la sua vocazione per una scultura ornata ed eminentemente pittorica” — his vocation for an ornate and eminently pictorial sculpture. In the San Bernardino relief the pictorial vocation is visible in the graduated projection of the carving, deepest in the Virgin and Child, shallower in the flanking angels and shallower again in canopy and frame; in the vibration of light across the fringed hems and hollowed folds; and in the taste for precious, textile detail that recalls the painted courts of contemporary Sienese altarpieces.

It must be stressed, however, that the comparison with Simone Martini is a critical interpretation, not a documented relationship: no source records any contact between the two artists, and the “alter ego” is a scholar’s metaphor, powerful but modern. Kreytenberg’s more sober assessment of Giovanni’s secure works — soft in modelling but heavy in proportion — is a useful counterweight, and it is worth remembering that in the dispute over the Cleveland relief both parties argue from this signed marble: for one reading its delicacy anticipates the Cleveland Madonna’s virtuosity, for the other the comparison between the two works reveals precisely the differences that give the Cleveland piece to the father.

What the relief does not tell us is almost as important as what it does. Its date is nowhere documented: the Dizionario Biografico degli Italiani places it around 1336, after the Tarlati chapel of 1334, while the museum literature offers the broader span of circa 1330–1340 adopted in the caption here. Its original location is unknown — nothing establishes that it was made for San Bernardino, whose confraternity complex is of later date, and the sources consulted are silent on how and when it arrived in the vestibule where it now hangs, secured by the modern mounting visible at the frame’s edges. Even its dimensions go unrecorded in the accessible literature: presumably they appear in the catalogue of the great 1982 exhibition of Sienese Gothic art and in the specialist articles of the 1980s and 1990s, but rather than guess, this essay gives none. Its intended function can only be inferred from its form: the modest scale, the self-contained frame and the canopied, tabernacle-like presentation suit a devotional relief, whether for a chapel, an altar or private veneration, but any more specific proposal would outrun the evidence.

The afterlife of the relief is a small parable of the historiography of its maker. Credited in some reference works and photographic archives to Agostino di Giovanni — the English-language description of the Oratory itself has called it “a marble bas-relief of the Madonna with Angels, by Agostino di Giovanni” — it has suffered, uniquely among signed Trecento sculptures, the indignity of being taken from its author by the simple reversal of his patronymic.

The inscription refutes the error as decisively as evidence ever can: “Ioh(anne)s magist(r)i Agostini de Se(n)is me fecit” names the son, not the father. That a work which announces its authorship in carved letters could still be misattributed measures the gravitational pull of Agostino’s inflated Vasarian fame, and explains why the recovery of Giovanni di Agostino required not only archives but attention — the willingness, quite literally, to read what the marble says. For the scholarship, and for anyone who reads what the marble says, this small Madonna is therefore doubly precious: a work of refined Sienese Gothic carving in its own right, and the single fixed star by which the whole disputed constellation of Giovanni’s oeuvre is navigated.

Marble and Fresco for a Fallen Knight: The Ciuto Tarlati Chapel of 1334

In the fifth bay of the right aisle of the Cathedral of Santi Pietro e Donato in Arezzo stands the one commission documented as contracted directly with Giovanni di Agostino that has come down to us intact. On 28 January 1334 Roberto Tarlati concluded the contract with the young Sienese master for a chapel to be modelled on the Ghini chapel of the Pieve — itself now destroyed — and erected in memory of Ciuto di Vanni Tarlati di Pietramala, cousin of the great bishop and lord Guido Tarlati, who according to the Enciclopedia Dantesca had died in 1327 at the siege of Pisa in the following of Ludwig the Bavarian. The chapel is therefore a memorial foundation, raised some seven years after the death it commemorates, and it belongs to the same campaign of dynastic self-representation that had produced, four years earlier, the cenotaph of Bishop Guido on the opposite wall. Of the documented Trecento chapels of the cathedral, the encyclopedic literature records that this one alone survives, which lends it a double preciousness: it is at once the key surviving document of Giovanni di Agostino’s activity as a designer of liturgical architecture and the sole witness to a whole vanished class of Aretine wall chapels.

The image shows the aedicule complete, and its architecture repays attention, for this is the family of forms from which, on the reconstruction accepted in the literature, the destroyed Pieve chapels of 1331 and 1332 can be imagined. Slender polygonal piers, articulated by clustered colonnettes and rising from tall moulded bases, carry richly carved foliate capitals; on the front face of each capital hangs a shield with the checky arms of the Tarlati. Above the capitals a broad arch spans the interval, its outer face and deep intrados offered to the painter, and the whole is crowned by a projecting cornice and a steep triangular gable edged with crockets and centred on a sculpted relief. The structure is thus a canopy of honour translated into monumental terms, a tabernacle magnified to enclose an altar, a tomb and a painted wall — and it is worth recalling that in the modern literature the Vallepiatta portal of the Duomo Nuovo in Siena has been judged structurally close to this very chapel, differing chiefly in its greater height, so that the modest Aretine aedicule stands at the head of a line that ends in what a Sienese scholar of the last century called the finest portal in all Sienese art.

Giovanni’s own chisel is responsible, on the account given in the Dizionario Biografico degli Italiani, for two sculptural elements only, both visible here. In the gable, Christ blesses between two praying angels and a seraph, a compact relief whose half-length Redeemer presides over the whole composition from the apex. On the lateral piers, above the armorial capitals, stand the two statuettes of the Annunciation: the angel Gabriel on the left pier, the Virgin Annunciate on the right, small figures in the round that turn the architecture itself into the theatre of the Incarnation, framing the Crucifixion between the message that opens the story of salvation and the sacrifice that fulfils it. Kreytenberg’s assessment of these marbles is famously guarded — he finds “forme voluminose e pesanti, anche se modellate morbidamente,” voluminous and heavy forms though softly modelled, with “non trascurabili debolezze nelle proporzioni” — and yet he insists that “queste sculture devono essere considerate punto di riferimento per tutte le attribuzioni”: these sculptures must be considered the point of reference for all attributions. Everything ascribed to Giovanni di Agostino, from Volterra to Cleveland to the Duomo Nuovo, is ultimately measured against the figures of this chapel and the signed relief in San Bernardino.

The chapel’s interior wall is given over entirely to painting — the Dizionario Biografico observes that the decoration was carried out mainly in fresco “presumibilmente per ragioni di spesa,” presumably for reasons of cost — and the result is one of the principal monuments of Aretine Trecento painting. Against a deep blue ground the Crucified Christ hangs on a tall cross whose titulus is borne on a red tablet; angels wheel about him, two at the top unfurling inscribed scrolls, others gathering the blood of his wounds in chalices, in the affective idiom of fourteenth-century devotion. At the foot of the cross the mound of Golgotha opens to reveal the skull of Adam, streaked by the falling blood, and against the shaft kneels a knight in full armour, hands raised to the cross — the donor, traditionally identified since Vasari as Ciuto Tarlati himself. Four monumental figures flank the scene in a solemn row: the Archangel Michael at the far left, sword point-down before him, courtly in rose and blue; the mourning Virgin wrapped in a dark mantle, hands crossed on her breast; John the Evangelist in a great ochre mantle, cheek resting on his hand in the ancient gesture of grief; and Francis of Assisi⁵, who blesses and holds a red book, his presence a reminder of the mendicant piety that shaped Tarlati patronage. On the inner faces of the piers, further saints stand in painted niches, and ornamental bands of rosettes and foliage knit the whole painted surface to the marble frame.

The archivolt carries its own painted programme. Within polylobed medallions set on a red ground, half-length saints and prophets appear along the intrados, attended by smaller angelic figures; at the summit, a mitred bishop holding a crozier presides — plausibly Donatus, the cathedral’s titular, though it should be said that this identification rests on descriptive guides rather than on any published titulus. No source distinguishes the hand of the archivolt from that of the Crucifixion, and the literature speaks of the chapel’s frescoes in the plural as a single campaign; same-hand authorship is thus the default reading rather than an independently argued conclusion.

Who that hand belonged to is a question with a long history and no documented answer. No contract, payment or signature names the painter. Vasari assigned the Crucifixion to “Berna sanese,” the elusive Barna of Siena, an attribution modern criticism has never accepted; instead, two studies of the 1960s built around this very fresco the figure of an anonymous Aretine painter of the first half of the Trecento, the “Maestro del Vescovado” — named after Vasari’s own word for the Aretine cathedral — to whom the chapel’s frescoes are now attributed by general consensus. Bartalini, whose name already anchors the modern literature on Giovanni di Agostino, devoted the fundamental study of 1996 to the Tarlati, the Maestro del Vescovado and Aretine painting of the period. The proposal to identify the anonymous master with Balduccio di Cecco, a painter documented in 1341 on the cathedral’s aisle vaults but without a single secure work, remains in the words of the recent literature “suggestiva, ma non documentabile,” suggestive but undocumentable, while the alternative suggestion that he is simply the young Andrea di Nerio is disputed, some scholars merging the two personalities and others keeping them apart. The frescoes themselves can be dated only to about 1334 or shortly after, in step with the marble frame built to house them.

Beneath the fresco, the funerary character of the ensemble becomes explicit. The tomb chest raised above the altar is a reused marble sarcophagus of the fourth century AD, its front carved with the rippling vertical flutes of the strigilated type between figured panels — a piece of Christian antiquity pressed into Trecento service, a practice that conferred on the deceased the prestige of the early Church and of Rome itself. Flame-crowned finial vases stand at its corners, and the tall base below carries long incised commemorative inscriptions of later date, flanking a small sculpted bust; these later texts, which are left undated here, record the afterlife of the monument as a site of memory. It should be noted that the photographic documentation of the chapel also records, under the label of a “double sarcophagus,” a second chest identified as the sarcophagus of San Satiro of 1340 from the old cathedral on the Pionta; this identification appears in image archives rather than in the scholarly literature, and it is recorded here as unverified rather than as a settled fact. One further correction belongs in this paragraph: the English-language reference literature, followed by derivative sites, describes the chapel’s reliefs as the work of “Agostino di Giovanni.” The contract of 28 January 1334 was concluded with the son, Giovanni di Agostino, and it is under his name that the sculpture must stand.

The chapel that the visitor sees today is the beneficiary of a recent conservative restoration, presented on 19 May 2021, in which the painted surfaces were treated by Manola Bernini and the stone by Sandro Ceccolini; the intervention arrested the lifting of the paint film and removed the disturbances of earlier retouchings and whitewashings, of which no dated record survives. What the restoration has clarified, above all, is the unity of a monument that scholarship must nevertheless keep analytically divided. The Tarlati chapel is a work of two authors and two media bound into one act of memory: a documented marble frame by a Sienese sculptor-architect of twenty-something and an undocumented painted Calvary by an anonymous Aretine master whose entire critical identity was born from this wall. For the study of Giovanni di Agostino it is the fixed point beside the San Bernardino signature; for the study of Aretine painting it is a foundation stone; and for the history of the Tarlati it is the quieter, more inward companion of the great cenotaph across the nave — not the celebration of a lord-bishop’s deeds, but a knight kneeling in his armour at the foot of the cross.

The Early Sienese Works and the Volterra Problem

Around the two fixed points of chapel and signature, scholarship has assembled an early catalogue whose items vary greatly in security. The Dizionario Biografico assigns two works to Giovanni’s earliest period in Siena itself: the Sacrament tabernacle with the Annunciation from Sant’Eugenio a Monistero, dated on stylistic grounds to 1331–32 and now in the chapel of Palazzo Chigi Saracini, and the gable relief of a monumental canopy in San Francesco in Siena, of about 1333–34, showing Mary Magdalene carried to heaven by two angels.

A Chapel in Miniature: The Chigi Saracini Sacrament Tabernacle

At the head of the catalogue that modern scholarship has assembled for Giovanni di Agostino stands a work that is neither signed nor documented: the marble Sacrament tabernacle with the Annunciation, carved for the church of Sant’Eugenio a Monistero just outside Siena and now preserved in the chapel of Palazzo Chigi Saracini. The Dizionario Biografico degli Italiani places it, together with the Magdalene gable in San Francesco, among the works that “appartengono certamente” to the sculptor’s earliest period, around 1331–32 — a formulation whose “certamente” expresses, it must be said at once, a scholar’s confidence rather than archival proof. No contract or payment ties the tabernacle to Giovanni’s name, and its date is a stylistic estimate; but if the attribution holds, this modest slab is the earliest surviving statement of his art, carved when he was barely out of his father’s tutelage, in the very years when the documents show him at work beside Agostino on the chapels of the Pieve of Arezzo. It is, so to speak, the seed from which the rest of the catalogue grows.

The object’s function explains its form. This is a wall tabernacle for the reserved Sacrament: at its centre opens the rectangular cavity, now filled with a neutral panel, in which the Eucharist was kept behind a door — presumably of metal, and long since lost — while the surrounding marble frames that humble aperture with all the honour that Gothic architecture could confer. Above the opening, within the head of the framing arch, the sculptor pierced the slab clean through with a large quatrefoil flanked by two clusters of small drilled trefoils; these openings, which let air and a glimmer of light pass to the recess behind, are at once ornament and — plausibly, though this is an inference from the type rather than a documented fact — a practical provision for the aired keeping of the Host. The result is a paradox typical of the best Trecento microarchitecture: a functional cupboard treated with the gravity of a cathedral façade.

Around the aperture, indeed, the tabernacle unfolds as a chapel in miniature. Two slender colonnettes with foliate capitals frame the door and carry its cusped arch; over this rises a tall crocketed gable, flanked by two lower bays, each containing a trefoil-headed niche under its own crocketed gable, the three summits separated by pinnacles with finials; and behind and between the gables runs an upper screen of small cusped lancets, their recessed grounds still holding, as the image shows with unusual clarity, substantial traces of red polychromy. The family of forms is recognisable at once: the tripartite front, the crocketed gables, the figured niches flanking a privileged centre are the grammar of the aedicule chapels that Giovanni and his father were building in Arezzo in precisely these years — the destroyed chapels of the priest Goro (1331) and of the Ghini (1332) in the Pieve, and the surviving Tarlati chapel of 1334 in the Cathedral. The tabernacle is that architecture compressed to the scale of a single slab, and its close kinship with the documented Arezzo aedicules is, in substance, the stylistic argument on which the attribution rests.

The figures enact the Annunciation across the sacred centre. In the left niche stands the archangel Gabriel, wings folded behind him, caught in the moment of arrival: his head with its cap of thick curls turns sharply toward the Virgin, his right hand rises in the gesture of speech, and his long tunic, girdled high, breaks into agitated hems about his feet. Beside him a damaged carved element survives, most naturally read as the remains of the lily or flowering stem he once presented, though its ruined state forbids certainty. In the right niche the Virgin Annunciate receives the word: a compact, heavily mantled figure, her veiled head bowed, her right hand drawn up to her breast in the gesture of troubled modesty, her left lowered with the book of her interrupted reading. Both figures are carved in high relief, nearly detached from their shallow niches, with the softly rounded faces, small features and fluent drapery that the literature associates with Giovanni’s beginnings — fuller and heavier than the elegance of the San Bernardino Madonna, and for that reason consistent with a date at the very opening of the 1330s.

The programme is completed in the central gable, where an oval medallion set amid carved foliage holds a half-length bearded figure — most naturally read as the blessing Redeemer presiding over the whole, though no published titulus or scholarly identification is available to me and the reading is offered as such. Taken together, the iconography is theologically exact in the manner of the best Eucharistic furniture. The Annunciation is the moment in which the Word takes flesh in Mary’s body; the tabernacle is the place in which that same body, sacramentally present, dwells within the church. By making Gabriel’s salutation pass across the very door of the Sacrament, the sculptor turns the liturgical cupboard into an image of the Incarnation itself: what the angel announces on the left and the Virgin conceives on the right is precisely what the priest places within the centre. This reading of the ensemble is an interpretation, not a documented intention — but it is the interpretation the arrangement itself insists upon, and it dignifies the modest object with a coherence worthy of its architecture.

A word should be said about colour, because the image preserves evidence that the literature consulted does not discuss. Red pigment survives extensively in the recessed grounds of the upper lancet screen, in the trefoils of the lateral gables, and in scattered patches along crockets, niches and mouldings. The tabernacle, in other words, was originally a polychrome object: its white tracery stood against coloured grounds, much as the figures of the San Bernardino relief stand today against their blue field, and the Ghini fragments in Paris retain their own traces of polychromy. The observation, made here from the image alone, matters for more than antiquarian completeness — it aligns this earliest attributed work with the “chromatic” sensibility that Bartalini’s account places at the heart of Giovanni’s mature relief style, as if the taste for colour and vibration were present from the start, achieved first with paint and only later with the chisel alone.

The tabernacle’s place in the reconstructed career is therefore pivotal despite its modesty. Dated to 1331–32, it is exactly contemporary with the first documents of Giovanni’s life — the payment of 31 March 1331 for the Goro chapel and the Ghini contract of 7 February 1332, which stipulated the young man’s collaboration — so that the attributed Sienese work and the documented Aretine work illuminate one another across the distance between the two cities. And it opens a thread that runs through everything that follows: the Annunciation flanking a sacred centre returns in the statuettes of Gabriel and the Virgin on the piers of the Tarlati chapel of 1334, framing the painted Calvary, and again, in the literature’s reconstruction, among the figures of the Vallepiatta portal of the Duomo Nuovo. If the attribution is right, Giovanni carved the Annunciation at every scale of his career — cupboard, chapel, cathedral portal — and this small slab is where the theme, and the architecture that houses it, first appear.

The condition of the work records a long and not always gentle history. The marble, veined grey in the Carrara manner, is abraded overall; the lower zone is crossed by cracks and losses, the frame is chipped along its edges, the original door and its fittings are gone, and modern metal clamps at the upper corners betray the present museum mounting. Of the tabernacle’s journey from the suburban church of Sant’Eugenio a Monistero to the chapel of the Chigi Saracini palace, the sources consulted record the fact but not the date or circumstances, and its dimensions go unpublished in the accessible literature; both points are left open here, as is proper. What survives, damaged and displaced, is nevertheless legible in full: the earliest surviving essay — if the shared judgment of the scholarship is right — of a sculptor who would spend his short life building canopies of honour around sacred presences, from this cupboard for the Host to the vastest church project of medieval Siena. Between the small pierced quatrefoil above this door and the great traceried façade of the Duomo Nuovo lies a single, brief, coherent career.

It is at Volterra that the attribution problem reveals itself in its sharpest form. The Museo Diocesano d’Arte Sacra there preserves two distinct groups of sculpture from Gothic tombs of saints. The first is the shrine of an unnamed saint that Kreytenberg’s study of 1990 assigned to Giovanni’s earliest independent activity, around 1331; its surviving members are read one by one in the sections that follow. The second group consists of sarcophagus reliefs with the Stories of Saint Victor and two accompanying angels, and it is here that the two principal modern readings of Giovanni part company most dramatically.

For Bartalini, these reliefs represent Giovanni’s most complex achievement in graduated, space-creating relief, datable “probabilmente sulla fine degli anni trenta,” probably at the end of the 1330s; his encyclopedia entry explicitly brands the attribution to Agostino “indebita,” unwarranted. Kreytenberg holds precisely the opposite: “non è possibile però che l’autore di queste sculture abbia eseguito anche i rilievi di sarcofago e due figure di angeli di un’arca di S. Vittore” — it is not possible that the author of the first group also executed the sarcophagus reliefs and the two angels of an arca of Saint Victor. Their slender, more sculpturally articulated figures fit better, he argues, with the work of Agostino, who would have carved them around 1324–25. The disagreement could hardly be more complete: one reading places the reliefs at the close of the 1330s and gives them to the son; the other pushes them back to the mid-1320s and gives them to the father. Fifteen years of chronology and a change of author separate the two positions, and no document exists to arbitrate between them.

A Fragment in Flight: Giovanni di Agostino’s Magdalene between Two Angels

High on the striped grey-and-white masonry of the Basilica di San Francesco in Siena, in the Cappella Turchi — the second chapel to the right of the Cappella Maggiore — hangs a triangular marble relief that most visitors pass without a glance, and that the modern literature counts among the earliest works of Giovanni di Agostino. The Dizionario Biografico degli Italiani places it, together with the Sacrament tabernacle from Sant’Eugenio a Monistero, among the pieces that “appartengono certamente” to the sculptor’s first period, dating it to about 1333–34 and describing it as the gable of a monumental canopy showing Mary Magdalene carried to heaven by two angels. As with the tabernacle, no contract or payment attaches to the relief, and its attribution rests on style alone. But if the judgment holds, this cusp is the Sienese twin of the Chigi Saracini tabernacle — a second surviving fragment from the years when the documents show the young sculptor commuting, so to speak, between his father’s Arezzo workshops and his native city.

The format itself is the first document. The relief is a cuspide, a steep triangle whose lower edge curves gently upward at the centre: it was carved, that is, to sit above an arch, crowning the front of some larger structure whose extrados its base once followed. The Dizionario Biografico calls that structure a monumental canopy — a ciborium or baldachin of the aedicule family — but nothing further is known of it: whether it sheltered an altar, a tomb or a venerated image, when it was dismantled, and how its gable came to be mounted alone on the chapel wall are questions the sources consulted do not answer, and they are left open here. What can be said is that the gable belongs to a genre that runs through Giovanni’s whole catalogue: the crocketed cusp of the Chigi Saracini tabernacle with its medallion, the gable of the Tarlati chapel of 1334 with Christ between angels and a seraph, and, in Bartalini’s reconstruction of the Duomo Nuovo campaign, the gabled half-figures of the Baptistery façade. The triangle over the arch was, for this sculptor, a recurring stage — and the Magdalene relief shows how inventively he could fill it.

The subject is the elevation of the Magdalene, one of the most beloved images of Trecento penitential piety. According to the legend consolidated in the Legenda aurea⁶, Mary Magdalene spent her last thirty years as a hermit in the wilderness, without food or clothing, sustained only by heaven: at each of the canonical hours angels raised her bodily into the air to hear the songs of the celestial choirs, and her nakedness was veiled by the miraculous growth of her own hair. It is this recurrent, almost liturgical levitation — not a single ascension at death — that the gable depicts, and the choice of subject speaks eloquently of its Franciscan setting. In the friars’ basilica the hair-clad penitent, weightless between angels, offered the perfect emblem of the order’s own ideals: poverty absolute, the body mortified into pure prayer, the soul already half in heaven. A canopy crowned by this image, whatever it sheltered below, placed everything beneath it under the sign of penance rewarded.

At the centre the Magdalene stands — or rather hovers — in strict frontality, her bare feet resting on the curved lower rim as on the crest of the arch below. She is clothed, in the legend’s own conceit, entirely in her hair: from her shoulders to her ankles the sculptor has wrapped her in unbroken parallel waves, a cascade of fine undulating striations that turns the whole figure into a single vibrating surface, at once garment, attribute and halo of penance. Only the face, the joined hands raised in prayer at her breast, and the feet emerge from this pelt of hair. The face is the soft, full oval familiar from the Chigi Saracini figures, small-featured and serene, tilted almost imperceptibly as if listening — to the celestial music, the legend would say — while the praying hands press through the hair as the one gesture the body still makes. It is a figure conceived with remarkable economy: no drapery, no throne, no attribute beyond the hair itself, which the chisel renders with the same delight in striated texture that would later clothe the Baptist of the Cleveland relief in his camel skin.

The two angels convert the awkward geometry of the cusp into the very image of flight. Each kneels-in-air within his diminishing half of the triangle, body inclined downward and outward, head turned up toward the saint; each grasps her — hands at her arms and sides — in the act of bearing her aloft; and behind each, wings spread wide and mantle-ends stream into the acute corners, so that the leftover space of the frame is filled precisely by the signs of motion. The symmetry is close but not mechanical: the poses answer one another with small variations in the set of the heads and the fall of the drapery, and the fluttering hems, snapping like pennants toward the angles, give the group a suspended, wind-blown animation rare in Sienese relief of these years. If the “pictorial” Giovanni of the critical tradition is the sculptor who made marble behave like painting, here — perhaps for the first time — he makes it behave like air.

The attribution data deserve to be set out plainly, because they do not entirely agree. The Dizionario Biografico assigns the relief to Giovanni’s earliest period, about 1333–34; the current descriptive literature on the basilica gives “1340 circa,” a date that would move it toward the capomaestro years; and the photographic documentation in the public image archives labels it, more cautiously still, as the work of an anonymous “scultore senese” of the fourteenth century. These are not contradictions to be resolved silently but the normal condition of an undocumented fragment: the attribution to Giovanni, argued from the kinship of the figures with the Chigi Saracini tabernacle and the Tarlati chapel sculptures, is the reading of the specialist literature, and the divergent labels record the residual prudence of the guides. The stylistic case is, in fact, easy to feel before this image: the full soft faces, the taste for fine striated texture, the graduated projection that lifts the Magdalene forward of her angels, and above all the gable format itself, handled with the same intelligence as at Arezzo one year later.

The relief’s condition and display tell the usual story of a fragment. The marble is worn and warmly patinated, chipped along the raking edges and abraded across the lower rim; the surviving surface nevertheless preserves the hair’s striations and the angels’ feathering with surprising freshness. Mounted high against the banded wall of the chapel, without the monument it was made to crown and — so far as the accessible literature records — without published dimensions, it must be read today as pure composition, a triangle of figures floating on the masonry. That very isolation, however, has its instructive side: stripped of its architecture, the gable shows more clearly than any intact monument how completely Giovanni thought of sculpture and frame as one — how the figures were invented for the triangle, not fitted into it.

For the reconstruction of the sculptor’s beginnings, then, this modest cusp carries real weight. With the Chigi Saracini tabernacle it forms the whole of Giovanni’s attributed Sienese production before the Tarlati contract of 1334: two fragments, a cupboard front and a gable, both orphaned from their settings, both assigned to him by style rather than by parchment. Yet between them they already contain his art in embryo — the microarchitectural intelligence, the soft full-faced figures, the textures that make light vibrate, and now, in the Magdalene, the new element of movement, of bodies genuinely airborne within the stone. When the young man signed the San Bernardino Madonna a few years later, and when his angels drew back curtains and unfurled scrolls across the marble of two cities, the wind that fills their draperies was first felt here, in the corners of a triangle in San Francesco, lifting a penitent clothed in her own hair.

The Dismembered Shrine: Giovanni di Agostino’s Volterra Arca

Giving Everything Away: The Distribution of Goods from the Volterra Arca

This nearly square panel, its recessed field sunk between plain raised borders, is the opening item of the Volterra group — the piece with which any reconstruction of Giovanni di Agostino’s earliest independent activity must begin, if that reconstruction is accepted at all. The image reproduced here comes from the fundamental study of the Volterra tombs, Kreytenberg’s article of 1990 on the three Gothic funerary monuments of the city, and its caption is itself the primary attributional datum: “Giovanni d’Agostino, Schrein eines Heiligen, Verteilung der Habe, um 1331” — Giovanni di Agostino, shrine of a saint, the distribution of his goods, about 1331. Every element of that laconic line carries weight. The author is the son, not the father; the monument is a saint’s shrine, an arca; the saint himself goes deliberately unnamed; and the date, around 1331, would make this relief exactly contemporary with the first document of Giovanni’s life, the payment of 31 March 1331 for the chapel of the priest Goro in the Pieve of Arezzo. If Kreytenberg is right, we are looking at the sculptor’s documented debut year in marble.

The shrine to which the panel belonged survives only as a scatter. From sculptures gathered into the Volterra museum from the cathedral and the bishop’s palace, Kreytenberg reconstructed three distinct Gothic tomb monuments: the Arca di Sant’Ottaviano with its tondo busts, which he gives to Tino di Camaino around 1320; a shrine with the Stories of Saint Victor, which he assigns to Agostino di Giovanni around 1324–25; and this third monument, the “Schrein eines Heiligen,” whose surviving members — the present relief and its companion showing the translation of the saint’s body, a figure lying in state, two angels drawing back a curtain from the burial chamber, a Madonna with two angels presenting what is presumably the patron, and a blessing Christ from a tabernacle — he composed into a canopied tomb of the type Tino di Camaino had fixed in Tuscany, with the curtain-angels revealing the gisant on the chest’s front. The identity of the saint honoured by all this is unknown: the German caption’s studied anonymity is matched in the Italian encyclopedic literature by the formula “già creduto s. Ottaviano,” formerly believed to be Saint Octavian — a former belief now withdrawn, leaving the shrine’s occupant one of the more distinguished anonymous saints of the Trecento.

The scene itself is a hagiographic topos of the purest kind. The distribution of one’s goods to the poor — the literal execution of the Gospel command, “sell what you possess and give to the poor” — is the threshold episode of countless saints’ lives, the act by which wealth is renounced and sanctity begins; on a tomb it functions as credential, setting the saint’s caritas before the pilgrims who came to his shrine. What the panel shows, then, is not an anecdote but a proof: the moment in which a man’s property changes hands and his life changes state. The sculptor has staged it as a genuine transaction. At the left the saint stands isolated, a full head taller than his beneficiaries, an elderly figure with bald crown, long parted beard and a heavy mantle over his tunic, his right hand extended downward with the gift; the empty space the composition preserves around him is the visual form of his detachment, the room that holiness keeps between itself and the world it is renouncing.

The gift itself passes at the panel’s centre, and its exact nature is worth a careful sentence. A mass of cloth hangs between the saint’s lowered hand and the small man who bows to receive it: the most natural reading is that the saint is handing down a garment — clothing the naked being among the canonical works of mercy — though one cannot exclude that the cloth is the recipient’s own, held open to catch alms poured into it, and the image does not decide between the two. The receiver is the relief’s most touching invention: a slight figure in a short, ragged tunic, bent almost double in profile, both hands raised to the descending gift, his whole body converted into a gesture of eagerness and thanks. The veining of the marble, streaking across his garment in the image, now reads almost as the rags themselves — an accident of the stone, no doubt, but one the black-and-white reproduction turns strangely eloquent.

Behind him press the poor, five men deep, and the sculptor has made of them a small taxonomy of Trecento poverty. A youth cranes forward at the rear; a stocky man in a shoulder-cape holds out at arm’s length a limp sack or pouch, waiting his turn to have it filled; an old man with a heavy beard watches from the second rank; and at the right edge a figure with his head wound in a wrapped cloth leans on a long thin staff, the beggar-pilgrim’s equipment complete, with one more capped head behind him. No two faces repeat: broad noses, heavy jaws, sunken cheeks, the whole physiognomic register of need, characterized to the edge of the grotesque yet without mockery. Where the saint is noble and generalized, his poor are particular — and that asymmetry is doctrine as much as style, for it is precisely the unidealized humanity of the recipients that measures the gift.

Read formally, the panel is an early manifesto of the manner the critical tradition calls Giovanni’s “pictorial” relief. The crowd is built in depth by overlap, heads lapping heads in two and three ranks; but more telling is the graduation of the carving itself, deepest in the bowing recipient, whose arm cuts free of the ground, progressively shallower through the middle figures, until the rearmost heads flatten toward the plane — projection following imagined distance, the slab becoming a field of space rather than a wall against which volumes are lined up. It is the same principle the literature finds in the Stories of the Baptist on the Arezzo font and, at its most complex, in the Volterra Stories of Saint Victor; and it stands at the furthest remove from the elder Agostino’s manner, the alignment of discrete plastic blocks on a flat abstract ground that the Cino da Pistoia sarcophagus displays so proudly. That the two Volterra shrines divide between the two poetics is, indeed, the heart of Kreytenberg’s argument, set out above: the author of this crowded, breathing panel cannot, for him, be the author of the Victor reliefs. On this panel, at least, the son’s name is the one the specialist literature offers.

None of which is what the visitor to Volterra will read on the wall. The current descriptive lists of the museum inventory the Trecento tomb reliefs as a single series of seven marble panels with “Stories of the lives of Saint Octavian and Saint Victor,” attributed wholesale to “Agostino di Giovanni and Agnolo di Ventura” — the old Vasarian pair, imported from the Arezzo cenotaph into a context where no document and no modern study supports it, with the two dismembered shrines fused into one and the saint’s withdrawn identity quietly restored.

The label is a small museum of errors in itself, and the caption proposed above corrects it on every point: the attribution belongs to the critical literature, not to the pair; the shrine’s saint is unnamed; and the group to which this panel belongs must be kept distinct from the Victor reliefs whose authorship is genuinely in dispute. One practical consequence of the collection’s history should also be recorded: the museum left its old seat in the bishop’s palace and has been housed since 2017 in the church of Sant’Agostino on Piazza XX Settembre, so that older references — including the “Museo d’Arte Sacra” of Kreytenberg’s own caption — point to an address the sculptures no longer inhabit.

The usual caveats close the file, and here they are stricter than usual. The image is a printed black-and-white reproduction, which permits composition and carving to be judged but not surface, patina or possible traces of colour; the lower edge of the panel shows losses and what appears to be a pale fill, consistent with the rough history of a dismembered monument; and no dimensions are published in the sources consulted. The attribution, the date and the reconstruction of the shrine are one scholar’s argued proposals, adopted here with their author named; the saint has no name at all. What is not in doubt is the quality of the invention: a man giving everything away, carved by a sculptor — twenty years old, if the dating holds — who already knew that the drama of charity lies less in the giver than in the crowd of hands that receives.

Bearing the Saint: The Second Relief of the Dismembered Volterra Arca

This is the companion of the Distribution panel: the second of the two narrative reliefs that survive from the chest of the dismembered saint’s shrine in Volterra, and the second image of the pair in Kreytenberg’s 1990 study, whose caption again supplies the frame within which the object must be read — “Giovanni d’Agostino, Schrein eines Heiligen, Translation, um 1331.” The same three claims recur: the author is the son of Agostino di Giovanni; the monument is the shrine of a saint whom the scholarship declines to name, the Italian literature conceding only that he was “formerly believed to be Saint Octavian”; and the date of about 1331 places the work in the very year of Giovanni’s first surviving document. Together the two panels formed the narrative front of the arca, and their subjects were chosen as a diptych of credentials: the Distribution shows the saint’s charity in life, the Translation shows his cult after death — the deed that made him holy, and the ceremony that made him venerated.

A translation scene carries a special charge on a tomb, because it is self-referential. What the relief depicts — the solemn transfer of the saint’s body to its place of honour — is precisely the act that founded the monument on which it is carved; the panel narrates, as it were, the birth certificate of the shrine itself, assuring the pilgrim that the bones within arrived by public, episcopal, liturgical act and not by chance. The genre had recent Tuscan precedents on the saints’ arche of the early Trecento, the family of monuments — Tino di Camaino’s sarcophagus of San Bartolo at San Gimignano among them — from which Kreytenberg derives the Volterra shrines; and the Volterra carver has staged it with an almost documentary sobriety: no miracle, no crowd of afflicted, simply the weight of a body and the men who carry it.

The saint lies along the whole upper register, borne shoulder-high, his body converted into the panel’s horizontal cornice. His head is at the left, tilted outward toward the viewer so that the face reads clearly: an old man with a long, carefully carved beard — recognizably the protagonist of the companion relief — eyes closed, features settled into the decorum of death, the head pillowed close against the shoulder of the mitred figure behind. One hand rests on the body, which is wrapped in a garment or pall whose folds spill down between the bearers and sweep in a long diagonal toward the right. And behind the corpse, along the top of the field, appears one of the panel’s finest inventions: a second file of bearers on the far side of the bier, present only as a row of bowed, tonsured crowns rising behind the body — heads flattened nearly to the plane, a procession’s depth conjured from a few domed curves of low relief.

The near file is given full plastic development. At the left rear walks the bishop, his mitre ornamented with a decorated band, his face set in grave profile; a thin vertical element beside him, much worn, may be the shaft of a crozier or processional cross. Before him a young, clean-shaven cleric — an acolyte to the bishop’s celebrant — extends an open hand toward the bier in a gesture of accompaniment or mourning. Then come the bearers proper: heavy-cowled, tonsured religious, their ample habits falling in soft tubular folds, one with an arm lowered to gather the trailing drapery, each head bowed a little differently under the shared weight. The physiognomies are individualized, but the register has shifted entirely from the companion panel: where the poor of the Distribution were characterized to the edge of the grotesque, the clergy of the Translation are composed, uniform in their gravity — expressiveness rationed according to decorum, the crowd of need exchanged for the community of office.

The procession has a destination, and the sculptor has built it into the field. The right quarter of the panel is occupied by architecture: a church rendered as a compact crenellated block, a cross planted at the corner of its parapet, and a round-arched portal opening deep into the relief, toward which every figure moves. Within the dark of the doorway one detail rewards patience: a small domed form fringed below, best read — the surface is worn, and the reading is offered with due caution — as the tonsured crown of a bowed cleric waiting just inside the threshold to receive the body, the church itself personified in a single inclined head. The bier’s feet-first orientation aims the saint directly at this opening; a few steps more and the corpse will pass out of the narrative and into the building — which is to say, into the very shrine the pilgrim stands before.

Set beside its companion, the panel completes a deliberately balanced pair. The Distribution is static, a confrontation across a held gift, all its energy gathered at a single point of exchange; the Translation is kinetic, a lateral flow running unbroken from the left frame to the portal, its rhythm beaten out by the succession of bowed tonsured heads like stresses in a line of verse. One panel accumulates figures toward the saint; the other strings them out behind him. If, as their subjects suggest, the two reliefs sat side by side on the chest front with the life scene preceding the posthumous one, the procession would have marched along the monument toward its right edge — the carved cortège dissolving, at the corner of the arca, into the real space of the church that housed it.

The style is of a piece with the companion, and the same critical stakes attach to it. Depth is built by graduated projection: the near bearers carved to full salience, the corpse in strong middle relief, the far file of heads and the architecture flattening progressively toward the ground — the slab treated as a space to be inhabited rather than a wall to be lined with volumes. This is the “pictorial” manner on which Kreytenberg rests his attribution of the shrine to the young Giovanni around 1331; the museum labels and the collection’s new seat are as described for the companion panel.

The condition caveats follow those of the companion panel, with the same severity. The reproduction is a printed black-and-white image, adequate to composition and carving but silent on surface, patina and any trace of colour; the lower edge of the field is abraded, with losses along the bottom strip where the bearers’ feet once read; the frame is chipped at several points; and no dimensions are published in the sources consulted. Attribution, date and the reconstruction of the shrine remain one scholar’s argued proposals, adopted here under his name, for a saint who has lost his own. What the panel itself secures is something rarer than a name: the sensation of weight in transit — an old man’s body riding a current of bowed heads toward an open door, carved by a sculptor who understood that the most persuasive proof of sanctity is the care with which the dead are carried.

The Revelation Interrupted: A Curtain-Angel from the Dismembered Volterra Arca

The third image of the Volterra shrine shows neither a story nor a saint but an attendant: “Giovanni d’Agostino, Schrein eines Heiligen, Engel, um 1331” — an angel from the shrine of the unnamed saint, and the most grievously damaged of its surviving members. What remains is a fragment bounded on the left by its original moulded frame and on the right by a long diagonal fracture that has carried away the lower right half of the slab; the angel survives almost entire, wings, face and both hands, while what those hands were doing survives only in part, in the swags of curtain along the upper edge and the fall of cloth from the raised hand, before the diagonal break cuts it off. The caption’s terms are by now familiar, and this piece adds the structural key to the whole reconstruction, for it is upon the surviving angels that Kreytenberg’s rebuilding of the Volterra monuments principally rests.

The angel’s function is legible from its pose even in mutilation. It belongs to the type of the curtain-bearing angel: a figure stationed at the end of the tomb chest, drawing back a great cloth to disclose the effigy of the dead lying in state behind it. The motif descends from the founding invention of the Italian Gothic tomb, the curtained chamber of Arnolfo di Cambio’s De Braye⁷ monument, and reached Tuscany in the redaction that matters here — the closed burial chamber whose front is a curtain parted by angels, as on the Della Torre tomb in Santa Croce from the circle of Tino di Camaino, the comparison on which Kreytenberg builds. In his reconstruction of the Volterra shrine, a pair of such angels stood at the two ends of the chest front, sweeping the curtain apart to reveal the gisant of the saint; the present fragment, with its frame on the left and its gesture directed rightward, is the left-hand angel of the pair, and the diagonal break has removed precisely the field where curtain and body once lay. The fragment preserves the actor and only part of the act.

What the act meant is worth stating, because the curtain is the most theologically charged piece of furniture on a Trecento tomb. To draw it aside is to perform a perpetual ostension: the saint’s body is not merely buried but shown, and shown by angels — the revelation of the blessed dead staged as a ceremony that never ends, every pilgrim arriving at the very moment of disclosure. On a shrine, the motif does double duty: it dignifies the corpse as a relic worth unveiling, and it casts the heavenly attendants as the true custodians of the body, the earthly clergy of the Translation relief finding their celestial counterparts here. The angel’s downcast eyes belong to this economy: the gaze is lowered toward the place where the effigy lay, directing the viewer’s attention to a body that the fracture has since abolished.

The figure itself is carved in confident high relief, the forward arm undercut from the ground. The angel stands with weight gathered on the left of the slab, torso turning rightward into the lost field; one arm rises high, its hand curling at the upper corner around what must have been the gathered upper edge of the curtain, while the other hand extends at waist height, wrist emerging from a thinly banded cuff, its fingers laid over the cloth. The zoom makes the pathos of the fragment exact: the hands still hold a curtain of which only a part remains, the gesture intact and the object half gone — as eloquent an image of the monument’s dismemberment as one could design.

The face declares its school at a glance. A full, softly fleshy oval; hair parted at the centre and waving to the neck; elongated, heavy-lidded eyes nearly closed in their downward glance; a small compressed mouth above a rounded chin — the sweet gravity of the Sienese angel, and specifically the physiognomy that recurs across Giovanni di Agostino’s accepted corpus. The family is recognizable: the same soft oval returns in the angels of the Ghini chapel fragments of a few years later — the London and Budapest angels, the Louvre Virgin — and matures in the Vallepiatta figures and the framing angels of the signed San Bernardino relief. If the Volterra dating holds, this head is the earliest of the line, the type already formed at the moment of the sculptor’s documented debut; and the comparison runs the other way too, for it is precisely the kinship of this angel with the securely later works that gives the attribution its purchase.

The subordinate carving repays attention. The wings are built as a taxonomy of plumage — small imbricated coverts scaling the shoulder, long striated primaries descending in parallel behind the frame edge — the left wing well preserved, the right abraded. The mantle crosses the body in ample diagonal folds, and its edge carries a continuously ornamented border, a carved embroidery running the length of the hem: a goldsmith’s refinement on a funerary attendant, and a habit of decorated hems that the later fragments of Giovanni’s corpus share. The drapery’s lower cascade breaks into the angular, folded-over pleats at the left margin, giving the fragment its one passage of hard geometry against the prevailing softness of face and cloth.

The critical and museographical frame is that of the companion reliefs, and can be summarized briefly. The attribution and the c. 1331 date are Kreytenberg’s argued proposals; the two surviving angel pairs among the Volterra marbles are what allow him to posit two curtained monuments and to divide the sculptures between father and son, this pair falling to Giovanni; Bartalini’s alternative reading of the Volterra material keeps a different distribution and chronology. Provenance is a scatter — the pieces were gathered into the museum from the cathedral and the bishop’s palace, and the Victoria and Albert Museum’s catalogue entry for its own Giovanni angel records sculptures displayed over the doorway of the bishop’s palace at Volterra, a likely station in this fragment’s wandering, noted here with due caution. Museum labels and the collection’s present seat are as set out for the Distribution relief.

The condition report is the saddest of the three. Beyond the great diagonal fracture, a long crack or deep scratch crosses the face from the forehead over the left eye to the cheek; the right wing is abraded; the frame is chipped; old fissures net the drapery; and, as with every image of this shrine, the black-and-white reproduction forbids judgment of surface and patina, while no dimensions are published in the sources consulted. Yet the fragment’s mutilation is also its meaning. A whole monument’s rhetoric of revelation has contracted into a single gesture: an angel with lowered eyes, holding open — delicately, permanently — a curtain that time has half torn away, before a saint whose very name has followed it.

Thrown into the Pull: The Right-Hand Angel of the Dismembered Arca

The fourth image of the Volterra shrine is the twin of the third, published under the identical caption — “Giovanni d’Agostino, Schrein eines Heiligen, Engel, um 1331” — and together the two fragments reunite, across their separate mutilations, the halves of a single ceremony. The first angel survived with its gesture intact and its object largely gone: a hand laid over the folds of a curtain of which only part remains. This second angel has kept the object. The upper left quarter of the fragment is filled with the curtain itself — a great gathered mass of swags, loops and cascading folds, seized at its knot by the angel’s raised hand — so that what the pair now offers the viewer is a strange division of labour: one fragment preserves the actor and only part of the act, the other the act in full. Read side by side, as they are presented here, they restore between them the whole rhetoric of the monument’s front.

The reconstruction within which they belong has been set out above and needs only its bearings here. On Kreytenberg’s rebuilding of the shrine, two angels stood at the ends of the chest front, parting a curtain to disclose the effigy of the unnamed saint within — the closed-chamber type of the Della Torre tomb in Santa Croce, descended ultimately from Arnolfo di Cambio’s curtained invention. The present fragment declares its station by its own logic. Where the first angel kept a moulded frame at its left and gestured rightward, this one is built in reverse: the figure lunges leftward in pure profile, its wing rising behind at the right, the relatively straight right edge of the slab plausibly near the original margin — the right-hand angel of the pair, then, leaning in toward the centre of the monument to seize the curtain and sweep it back toward its own end. And along the top of the fragment runs the detail that binds the whole front together: a rippled horizontal border of small gathered pleats, the curtain’s upper hem riding its rail, which must have stretched continuously across the chest from angel to angel above the saint’s body.

The action is carved with an energy the first fragment only implied. The angel does not stand and hold; it pulls. The whole figure is thrown into a diagonal, head and shoulders driving leftward past the vertical, the forward arm — its sleeve rolled or banded at the elbow — thrust up to the point where the curtain gathers into a knot of folds. From that grip the cloth’s geometry unfolds with complete logic: a taut V-shaped fold hangs between hand and face, long swags loop away toward the upper corner, and a sheaf of vertical folds cascades below the fist, the weight and resistance of heavy fabric rendered as accurately as the anatomy that masters it. This is drapery as physics: one can read from the carving alone that the curtain is ample, heavy, and half-way through its journey.

The enlargements yield one further discovery, easily missed at page scale. At the angel’s waist the second hand appears — lowered, fingers extended downward, pressing a gathered sheaf of cloth against the hip. Two readings are possible and both are offered: the hand may clasp the lower mass of the curtain itself, hugging the gathered cloth to the body as one drags a heavy tent-flap aside, or it may simply secure the angel’s own mantle against the momentum of the pull. On either reading the invention is the same: the entire figure, from raised fist to pressing fingers to braced stride, is organized around a single continuous effort, and the sculptor has made the effort legible in every fold that the motion drags into tension down the figure’s back and flank.

The head bows into the action, and its profile confirms the family resemblance. The forehead-to-nose line runs clean; the mouth is small above the same heavy rounded chin; the hair is drawn back in waves over the ear to the nape; the eye, worn but legible, is cast steeply downward — toward, once again, the place below and to the left where the gisant lay, so that both angels of the pair directed the viewer’s gaze to the revealed body between them. The wing, better preserved than its twin’s, displays its imbricated coverts in neat overlapping rows. It is the identical Sienese physiognomy catalogued in the previous fragment — the soft oval, the lowered lids — here rotated into profile and bent to labour.

Taken together, the two fragments correct an assumption the reconstruction alone might invite: the pair was not rigidly mirror-symmetric. One angel presents itself nearly frontally, holding its hem with a jeweller’s delicacy; the other turns full profile and hauls with its whole body. The variation is deliberate and telling — a young sculptor refusing the heraldic stiffness that the curtain-angel formula easily produces, and differentiating his attendants, as his crowds are always differentiated, by temperament. It is the same instinct for the particular that fills the Distribution panel with unrepeated faces, and it anticipates the paired framing angels of the later Ghini fragments and the signed San Bernardino relief, where symmetry is likewise animated rather than frozen.

Condition, finally. The fragment is trimmed irregularly on the left and below, a large diagonal loss carrying away the lower left field and the front of the figure’s advancing leg; the tunic’s hem survives at the lower right with its final cascade of angular overfolds; surfaces are abraded and spotted with encrustation, the eye area worn; and as with every image of this shrine the black-and-white reproduction withholds surface and patina, while no dimensions are published in the sources consulted. Yet of all the shrine’s dispersed members this is the one that best resists its own fragmentation, because its subject is effort, and effort survives mutilation: an angel caught mid-pull, the heavy cloth yielding, the hidden saint — nameless now in every sense — forever on the point of being shown.

The Saint the Angels Revealed: The Effigy of the Dismembered Arca

With the fifth image of the shrine — “Giovanni d’Agostino, Schrein eines Heiligen, Figur des toten Heiligen, um 1331” — the apparatus of the Volterra shrine closes its circuit. The two preceding fragments showed the angels straining at the curtain; here, at last, is what the curtain concealed: the figure of the dead saint himself, lying full length, the object of the entire machinery of revelation. In Kreytenberg’s reconstruction the effigy occupied the chest front within the closed burial chamber whose cloth the angels drew apart, so that reading these images in sequence repeats, in the mind, the ceremony the monument performed in stone: the pull, the parting, the disclosure.

The type deserves a word before the figure. A gisant on a saint’s shrine is not quite the same creature as a gisant on a cardinal’s or a jurist’s tomb. There the effigy commemorates a body that decorum keeps hidden; here it advertises one — the relic itself, the shrine’s whole reason for being — and the curtain-and-effigy apparatus of the closed chamber, in the Tuscan redaction descending through Tino di Camaino’s monuments, converts commemoration into ostension: the carved body stands perpetual proxy for the holy one within, displayed at the very moment of unveiling. The Volterra figure is carved accordingly in high relief against its slab, not in the full round of a free-standing tomb-top effigy, and its slight rotation outward — head tilted toward the spectator, body turned a few degrees off the pure profile — belongs to the same logic: this is a body arranged to be seen through a parted curtain, by a pilgrim standing before the chest.

The figure also completes a portrait series the shrine has been conducting all along. This is the third appearance of the same man: alive at the left of the Distribution panel, handing down his goods; dead and shoulder-borne in the Translation, his face tilted outward from the bier; and now displayed in state, the terminus of both narratives. The long parted beard is the constant that binds the three — the shrine’s internal system of recognition — and the correspondence is itself an argument for the coherence of the ensemble: whoever carved the reliefs and the effigy was carving, deliberately, one man three times, at three stations of his passage from charity to cult.

The pose is of the utmost economy. The saint lies straight, legs extended, and the enlargement of the mid-section resolves what page-scale reading misses: the hands are crossed at the wrists upon the body, one laid over the other, the fingertips of the under hand emerging beneath the upper palm, both wrists finished with narrow banded cuffs — the oldest and quietest of funerary gestures, self-possession carried into death. He wears the hooded habit of a religious, the cowl drawn up to frame the head and bunched beneath it in a soft roll that serves in place of a pillow; the head lies low, barely raised, tilted outward. From the crossed hands the drapery runs to the feet in long, shallow, parallel channels — rivers of folds following the body’s length, gathering into convergent V-folds over the legs — and at the hem a worn rounded form emerges, crossed by a strap-like band that suggests a sandalled foot, though the surface is too abraded for certainty.

Even at the distance of the full-length view, the head announces a naturalism that the close reading below examines. What the whole-figure image adds is the relation of that head to the body’s grand calm. The face is the one zone of incident in a figure otherwise reduced to long horizontals; everything below the beard is stilled into the fold-channels’ slow parallel flow, so that the effigy reads as a single quiet ridge of drapery culminating in a face. The contrast with the flanking angels could not be more pointed, and was surely the point: their diagonals, their effort, their heavy hauled cloth — and between them this absolute horizontal repose. The monument’s front was a composition in tension and release.

Stylistically the effigy speaks the language of the rest of the shrine. The drapery is soft, tubular, unhurried, closer to the ample habits of the Translation’s bearers than to the angular cascades of the angels’ hems; the relief is graduated, the body swelling from the slab without breaking free of it; and the carving of the beard — articulated in wavy locks punctuated by rows of drilled dots, a virtuoso passage analysed below in the close reading of the head — supplies the kind of technical signature by which hands are recognized, inviting comparison with the patterned hair and camel-skin textures of Giovanni’s accepted works of the following years. If the c. 1331 dating holds, the effigy stands at the head of the sculptor’s line of carved textures, as the curtain-angel stands at the head of his line of sweet-faced attendants.

The critical and museographical frame is that of the other fragments of the shrine. Whether the effigy is displayed today in visible relation to its angels and reliefs is a question that only examination on site can settle.

A note on condition and caveats follows. The surface is generally abraded, most severely at the feet; the slab’s edges are chipped; the black-and-white reproduction withholds surface, patina and any trace of polychromy, of which effigies of this class often carried at least accents; and no dimensions are published in the sources consulted. What no abrasion has touched is the invention’s gravity. Of all the shrine’s members this is the simplest — an old man in his habit, hands crossed, lips just parted — and the most necessary: the still centre around which angels laboured, processions marched and the poor once crowded, a body carved to be perpetually shown by a monument that history has since taken apart around it.

Drill-Work and Silence: A Close Reading of the Dead Saint’s Head

The sixth image of the shrine — “Giovanni d’Agostino, Schrein eines Heiligen, Kopf des toten Heiligen, um 1331” — brings the reader as close as it is possible to come to the shrine’s protagonist: the head of the effigy, filling the frame, every tool-mark legible. It is the detail that justifies the whole reconstruction emotionally, for after the labouring angels and the marching bearers this face is what the monument’s machinery existed to show; and it is also, on the quality of its carving, the attribution’s best single exhibit. The close view adds what no caption can: the evidence of a sculptor thinking at the scale of a centimetre.

What the face renders, first of all, is death — observed, not euphemized. The eyes are closed beneath lids carved as true anatomical structures, their curved seams distinct, sunk in deep orbital hollows; the cheeks have fallen; the brow is marked by a single vertical groove at the centre and the flesh has fallen into the hollows of age; and the lips are slightly parted — the small, unidealizing detail on which the whole head turns. A sleeping face keeps its mouth composed; a dead one lets it fall open. The sculptor has chosen the second, and with it an entire poetics: this is not the diplomatic slumber of official tomb sculpture but the fact of a body from which breath has gone, dignified without being denied. The tension between decorum and observation — a face at once venerable and unmistakably dead — is the head’s achievement, and in the Sienese sculpture of the early 1330s a remarkably advanced one.

The cowl is the face’s architecture. Drawn up around the head, the hood encircles brow, cheeks and jaw in a continuous soft frame, its edge running an unbroken oval from crown to shoulders, where it settles into the heavy roll noted in the discussion of the full figure. The framing does double duty: formally it isolates the face as a medallion isolates a profile, concentrating the viewer’s attention on the one zone of incident in the effigy’s long calm; iconographically it declares the man a religious — a monk’s or hermit’s habit, consonant with the eremitic traditions attached to Volterra’s saints, though the identification of the wearer, as throughout the discussion of this shrine, must be left where the scholarship leaves it, with a saint “formerly believed” to be Octavian and now securely no one.

The beard is the passage a craftsman would cross the room to see. It descends from the moustache in long parallel waves, ending in a single rounded mass at the chin, and down the crest of each lock runs a line of drilled dots — regular, deliberate rows of small deep holes, punched with the running drill, following the strands like stitching. The device is at once optical and textural: at viewing distance each dot is a trap for shadow, so that the beard sparkles with dark points and reads as deeper and more vibrant than its actual relief; close up, the dots declare their artifice with almost ornamental candour. It is a virtuoso’s solution to the oldest problem of marble — how to make stone hair look like anything but stone — and it constitutes precisely the kind of technical signature by which hands are traced. It can be set beside the patterned parallel waves of the Magdalene’s hair on the Siena gable and the punched, pelleted texture of the Baptist’s camel skin on the Cleveland relief: three answers, across the accepted corpus, from one mind unusually interested in the graphic patterning of texture.

Above the hood’s edge the register changes. The crown’s hair escapes in genuinely plastic curls — thick, deeply undercut spirals quite different from the beard’s drawn-and-drilled waves — so that the head displays, within a few centimetres, two distinct systems of carving hair: the sculptural and the graphic, mass and pattern. The face between them is modelled in broad, quiet planes, the strong nose ridged, the cheekbones surfacing through the fallen flesh, the philtrum and the parted lips cut with particular delicacy. Age is rendered structurally, not cosmetically: it is in the subsidence of the cheeks and the groove of the brow, not in any multiplication of surface wrinkles.

Is it a portrait? The question presses harder here than anywhere else on the shrine, because the head is individualized well beyond the requirements of the type — and because, as the discussion of the full figure observed, this is the third rendering of the same physiognomy on the shrine. Whether the carver worked from a death-mask tradition, from the relic itself, or simply from a strong invention consistently repeated cannot be known and should not be pretended; what can be said is that the monument was designed to make its unnamed saint recognizable, and that the effigy’s head is the master version from which the narrative faces read as reductions. Individuation, here, is not biography: it is the visual grammar of authenticity.

The critical frame is that of the other fragments of the shrine. If the head is to anchor the young Giovanni’s beginnings, it does so on quality: the drilled textures, the soft ovals, the observed naturalism are the traits the securely attributed works of the following decade develop, and this face, on the proposed dating, is where they first cohere.

Condition, last. The nose tip and brow show surface wear; small chips and encrustations spot the cowl; the black-and-white reproduction — generous as it is at this scale — still withholds patina and any trace of the polychromy that heads of this class often carried in the eyes and lips; and no dimensions are published in the sources consulted. None of it diminishes the essential fact this detail preserves. Six centuries after his shrine was taken apart and his name detached from his bones, the saint of Volterra keeps the one identity that survives dismemberment: a particular dead face, lips just open, framed in its hood — carved by a sculptor barely at the start of his own record, who gave an anonymous man the most durable kind of remembrance he had to offer.

The Receiving Pole: The Madonna and Child from the Dismembered Arca’s Crown

The seventh image of the shrine climbs to the top of the monument. “Giovanni d’Agostino, Schrein eines Heiligen, Madonna der Präsentationsgruppe, um 1331”: the Madonna of the presentation group — that is, the crowning register of Kreytenberg’s reconstructed shrine, where a seated Virgin and Child received a kneeling figure, presumably the monument’s patron, ushered forward by two angels. The image shows the group’s centre alone, the Madonna with the standing Child, a free-standing statue photographed against a wall of rough masonry; the presenting angels and the devotee are separate survivors of the scatter. This piece adds a new register of pathos to the shrine, for of all the shrine’s members it is the most cruelly weathered: a sculpture whose surfaces the open air has half dissolved, and whose meaning has nevertheless survived in its bones.

Its function first. A presentation group converts the summit of a tomb into a transaction: the mortal kneels, angels commend, the Virgin receives — the commendatio of the soul staged permanently in marble, in the tradition the great Tuscan canopied tombs had fixed. On a saint’s shrine the motif doubles the monument’s traffic in a striking way. Below, on the chest, angels drew a curtain to show the holy body to the pilgrims; above, angels ushered a praying mortal into the presence of the Virgin. Two revelations, pointed in opposite directions — the saint displayed to earth, the patron presented to heaven — with the Madonna enthroned at the hinge. She is the receiving pole of the whole apparatus, and her group’s orientation, as will be seen, is built around the encounter.

The statue itself is a frontal pyramid: the Virgin seated, a veil falling from her head over the shoulders, her mantle descending in what were once rich cascades to a broad base of drapery, the hems still breaking into legible zigzag folds at the plinth. Across her lap runs a gathered diagonal swathe of the mantle, and on its far end, upon her left knee, the Child stands — fully upright, a small solid figure in a belted, knee-length tunic, one foot planted on the drapery mound, the whole vertical of His body breaking the pyramid’s symmetry at her left side. A standing Child is the composition’s event: not cradled, not seated in majesty, but on His feet, with the sturdy, faintly precarious uprightness of a real infant standing on a real lap.

And He is doing something. From His right shoulder an arm extends toward the Mother, terminating — the marble is broken — in a damaged mass at her shoulder and neck: the Child reached for her face, her chin or the edge of her veil, the tenderest gesture in the Marian repertory, and she answers it, for her head inclines toward Him off the vertical axis. The affective circuit is complete even in ruin: His reach, her inclination. His head meanwhile turns on His own axis, the glance directed away and outward — toward, in the reconstructed group, the quarter from which the kneeling patron approached — so that the small figure performs two offices at once, caressing the Mother and attending to the supplicant. His face is the best-preserved passage of the statue: round and full-cheeked, small-mouthed, the hair a close cap with a heavy curl massed over the ear, still recognizably of the same family as the Child of the signed San Bernardino relief.

The Mother’s part is quieter and more damaged. Her face has been effaced almost to a mask — the nose worn away, the eyes shallow depressions, the mouth a slit, a long fracture running diagonally from temple to jaw — yet the essential is intact: the oval, the framing veil, and above all the inclination, the pose outliving the face. Her right hand, worn to a mitten, rests on her knee pinning the lap-swathe of the mantle — she steadies, characteristically, not the Child but the cloth He stands on. Her left hand is lost or hidden behind Him, and the mutilations leave the supporting system partly conjectural: the broken forms at the Child’s flank may belong to His lowered left arm, to her vanished hand, or to both. The ambiguity is declared here rather than resolved.

The weathering itself is a document. Erosion of this depth and evenness — drapery edges melted, features dissolved, the surface pitted overall — is the signature of long exposure to open air, and the literature supplies the likely station: sculptures from this scatter were once displayed over the doorway of the bishop’s palace at Volterra, an outdoor exile that would account exactly for what the statue has lost. The loss has epistemic consequences that an honest entry must own. Attribution by morellian detail — the cut of an eyelid, the drilling of a curl — is barely possible on surfaces like these; the case for Giovanni’s authorship rests here on membership in the reconstructed ensemble and on what erosion cannot remove, the composition and the affective invention, with the Child’s sheltered face as the one passage where the sculptor’s hand is still legible. Those who wish to test the attribution should set that face and the group’s tender mechanics beside the Louvre Virgin from the Ghini chapel of a few years later — the corpus’s nearest intact kin.

The critical and museographical frame is that of the other fragments of the shrine. Whether the Madonna now stands in visible relation to her angels, her kneeling patron and the shrine below is a matter for examination on site.

Condition closes the discussion, and here it nearly is the whole of it: general deep erosion; the Virgin’s features effaced and her face fractured; the Child’s reaching arm broken at the hand, His lowered arm damaged; the Mother’s left hand lost or concealed; the black-and-white reproduction withholding whatever the surface might still confess of tooling or colour; dimensions unpublished in the sources consulted. And yet the statue demonstrates something the better-preserved members of the shrine cannot: how much of Trecento sculpture’s meaning is carried below the surface, in disposition rather than finish. Rain has taken the Virgin’s face and left her attention; taken the Child’s hand and left His reach. What the presentation group presented — tenderness at the summit of a machine for showing the dead — is still, against six centuries of weather, being presented.

Between Two Angels: The Empfohlener of Volterra

The eighth image of the shrine — “Giovanni d’Agostino, Schrein eines Heiligen, Engel und Empfohlener der Präsentationsgruppe, um 1331” — pairs two photographs, and the pairing is not decoration but method: the two views walk the reader around a single sculptural block, and only together do they disclose what it is. Seen from the left flank, a standing angel lays a hand on a small kneeling figure whose profile lifts to the right; seen from the right flank, a second angel — differently coiffed, differently occupied — stands over the same kneeling figure, whose profile now lifts to the left, as profiles do when the viewer, not the statue, has changed sides. The group thus resolves into three figures: the Empfohlener, the commended one, kneeling between two angels who present him — the escort that Kreytenberg’s reconstruction places beside the seated Madonna at the summit of the shrine, and that the previous fragment left waiting in the wings.

With this block the presentation group is structurally complete. The Child looked away from His Mother’s caress toward an approaching supplicant; here is the supplicant approaching, aimed by his angels at precisely that glance. And like the curtain-angels on the chest below, the transaction is staffed by angels, the monument’s tireless intermediary class.

The commended figure is the shrine’s one certain portrait of a living contemporary, and its most tantalizing anonymity. He kneels compactly, robed, at little more than half the angels’ standing height — hierarchy and humility conspiring in the scale — with his head thrown back, the young face lifted in profile toward where the Virgin sat. His hair is cut in the rolled bob of the Trecento layman, the zazzera curling under at the nape: not a cleric’s tonsure, not a lady’s veil, but the fashion of a young man of standing. One open hand rises beside his face in the astonished, orant gesture of adoration; the other bends before his breast. Who he was — donor, patron, a member of whatever family or chapter paid for the shrine — is exactly as lost as the name of the saint he knelt before; the German caption’s Empfohlener, “the commended one,” is now his whole identity, and this account keeps it for him.

The two angels are the passage where the sculptor’s temperament declares itself, for they are pointedly not a matched pair. The first — call him the angel of the hand — wears his hair in loose waves bound by a band across the brow; his garment carries an embroidered border at the neckline, with a rosette legible in the worn relief; and his office is tactile: he lays on the kneeling man’s back a hand carved noticeably large, fingers spread wide, a gesture of guidance amplified almost to guardianship. The second — the angel of the voice — is the image’s revelation. His coiffure is dressed in ornamental coils, spiral curls articulated with the running drill in a band from temple to neck; one long-fingered hand spreads on his own breast; and his lips are parted. The mouth is open. This angel is speaking — carved in the act of pronouncing the commendation itself, the celestial advocate presenting his client aloud — and with that single detail the group acquires a soundtrack: the summit of the Volterra shrine was not a tableau but an utterance, permanently in progress.

The choreography of hands binds the three figures into one action. From one side, the large spread hand on the back, urging the kneeler forward; from the other, the second angel’s hand descending onto his shoulder; between them, the patron’s own hands rising in answer — five hands in a chain of transmission, pressure converted into prayer. The group is carved to dock with the Madonna: every vector in it, the kneeler’s lifted profile, the angels’ framing verticals, the spoken word itself, discharges toward the vanished throne, so that in the museum’s present scatter the block gestures perpetually at an empty space — as the curtain-angel grips a hem that is gone, and the effigy lies in state for no one’s unveiling.

Stylistically the group both confirms the shrine’s signatures and complicates its condition-map. The drilled coils of the speaking angel are the third appearance of the running drill as ornament, after the dotted beard of the gisant — a technical habit fast becoming this workshop’s fingerprint, and the natural comparandum for the patterned textures of Giovanni’s accepted works of the following years. The refusal of symmetry in the angelic pair repeats, at the monument’s summit, exactly what the curtain-angels showed on its chest: one attendant frontal and delicate, one in effortful profile there; one tactile, one vocal here — differentiation by temperament as a compositional principle. And the surfaces, though crossed by long fissures and veining, with breaks at the shoulders where the wings have gone, are markedly better preserved than the dissolved Madonna beside which the group stood: a contrast that suggests different stations in the ensemble’s outdoor exile, and that examination in Sant’Agostino might yet explain.

A note on condition and caveats follows. Long cracks traverse both angels’ faces and bodies; the wings survive only as stumps; the kneeler’s surfaces are netted with fissures; the black-and-white reproduction withholds patina, tooling and any trace of colour; and no dimensions are published in the sources consulted. What survives intact is the group’s argument, which is also the shrine’s: that between the human and the holy there stands a courteous, laborious traffic of intermediaries — angels who pull curtains, carry meaning, lay hands on shoulders and speak on one’s behalf. The young man of Volterra bought himself the best advocacy the Trecento imagination could carve. Six centuries on, his angel’s lips are still parted on his behalf, addressing a Madonna who is no longer there — the most eloquent unfinished sentence in the whole dismembered monument.

A Niche, a Gable, a Blessing: The Last Fragments of the Volterra Arca

The ninth and final image of the shrine — “Giovanni d’Agostino, Schrein eines Heiligen, Fragmente eines Tabernakels mit Relief Christi, um 1331” — shows not a figure group but a piece of micro-architecture in ruins: two fragments of a marble tabernacle, photographed as they were displayed, set directly into the plaster of a museum wall with mortar smearing their edges. Above hangs a triangular gable bearing the half-figure of Christ in a mandorla; below, separated by a stretch of bare wall that the original assembly certainly did not include, sits the tabernacle’s front — a cusped arch opening into a dark cavity, flanked by two carved pilaster strips. The image thus documents two things at once: the last members of the shrine’s scattered family, and a chapter of their afterlife, the old immured display whose gap and mortar are themselves part of the object’s history.

How a tabernacle belonged to a tomb is the one structural question that must be left in suspense. The caption binds the fragments to the “Schrein eines Heiligen” without stating their station, and more than one is conceivable: the Christ gable and niche may have crowned the monument’s canopy; or the ensemble may have been a wall tabernacle serving the shrine’s altar — a receptacle for relics, keeping the saint’s treasure accessible beside his arca, or a sacrament house of the kind the young Giovanni was carving in precisely these years. The article’s reconstruction drawings would have to adjudicate among these; the account here records only what the caption warrants, membership in the ensemble, and what the stones themselves declare.

What they declare, first, is a void. The lower fragment’s centre is a deep niche — the dark cavity that dominates the image — framed by an arch of some sophistication: the inner profile is cusped, a trefoil edging the opening, while the outer moulding rises through an inflected curve to an ogee point at the apex, now broken. The right half of the inner cusping has been torn away, leaving the cavity’s edge ragged, so that the niche gapes slightly wider than it was designed to. The spandrels between arch and lintel are carpeted with dense stellate foliage, star-flowers packed edge to edge — a horror vacui of ornament pressing in on the emptiness it frames. Whatever the niche once held — relic, pyx, or vessel — its loss makes the fragment an unintentional emblem of the whole shrine: a richly worked frame around an absence.

The flanking pilaster strips carry the tabernacle’s vegetal order. Each bears, within a sunk rectangular field, a running vine scroll — a thick sinuous stem coiling through loops and throwing off broad leaves, deeply undercut so that the shadows do half the drawing. The two strips are not identical: the left fragment, its lower corner sheared diagonally, winds its scroll in free loops; the taller right strip disciplines its vine into a chained rhythm of ovals. They need not be symmetrical mates from a single pair of jambs — a tabernacle offers several stations for such strips — and there is no reason to force them into one; what they share is the carver’s evident pleasure in the motif, the same botanical appetite that sends leafy sprays climbing the gable above.

The gable is the ensemble’s voice. Within its triangle, a pointed mandorla with a doubled rim encloses the half-figure of Christ: bearded, long-haired, the halo inscribed with a cross, the right hand raised in blessing before the breast, the left steadying a closed book at the mandorla’s lower rim. The figure emerges to the waist, the drapery banding horizontally where the mandorla cuts it — the apparition formula, Christ not seated in a scene but manifested in a frame. From the triangle’s lower corners foliate sprays sprout and climb the raking sides, each corner anchored by a small round boss, a rosette or possibly a minute mask, the wear leaving the alternative open; at the apex a trace of a finial survives. The type is the Redeemer of the cuspide, the blessing Christ who crowns Trecento gables, and its presence names the tabernacle’s theological office: whatever the niche held, it held it under that hand.

The fragments dock into Giovanni’s corpus with unusual neatness. Their closest sibling is the Sacrament tabernacle of the Chigi-Saracini collection, carved around 1331–32 — the same debut years, the same genre of micro-architecture, the same grammar of cusped niche, ornamented spandrel and crowning gable — so that, if the Volterra dating holds, the young sculptor was producing tabernacles at both ends of the diocese’s roads at the very start of his record. And the gable itself extends a habit of the corpus: the triangular field with a single sacred figure recurs in the Magdalene gable of San Francesco in Siena a few years later. More largely, the Christ completes the shrine’s theology. The shrine climbs a chain of intercession — the saint’s charity shown to the poor, his body shown to the pilgrims, the patron shown by angels to the Virgin — and here is the chain’s last link and first cause: above all the monument’s laborious traffic of showing, a blessing hand raised over everything, the final instance before whom even the Madonna of the presentation group held her court.

The critical and museographical frame closes as it has run throughout: both the caption’s “Museo d’Arte Sacra” and the plastered wall belong to a superseded display, and whether the fragments are still shown together, and how, is not recorded in the sources consulted.

Condition and envoi. The apex of the ogee is broken, the right cusping lost, the pilaster corner sheared, surfaces worn, edges buried in mortar; the black-and-white reproduction withholds patina and tooling; no dimensions are published in the sources consulted. Taken together, the nine images reassemble on the page, as nowhere in Volterra since the monument was taken apart, the ensemble: the saint giving, the saint carried, the saint displayed between his straining angels, the patron spoken for before the Virgin and her standing Child, and over it all this Christ, still blessing from his triangle a machine of marble that no longer exists. The reconstruction is one scholar’s argument; the fragments are facts; and between the two, the unnamed saint of Volterra has recovered everything but his name.

The Sculptures of Giovanni di Agostino in the Pinacoteca Nazionale di Siena

There is a quiet paradox in looking for Giovanni di Agostino in the Pinacoteca Nazionale di Siena. The gallery in Palazzo Buonsignori is the temple of Sienese painting — the largest gathering anywhere of the gold-ground panels of the Trecento and Quattrocento, Duccio to Simone Martini to the Lorenzetti — and a sculptor is, by definition, its guest. Yet no sculptor of his century has a better claim to hospitality here than Giovanni, because no sculptor of his century painted so insistently in marble. The critical tradition’s very name for his manner, the rilievo pittorico, declares the debt: relief graduated like atmospheric distance, grounds that swell and recede like landscape, crowds built the way the painters built them. In the recently rearranged hall of stone sculptures on the museum’s second floor — the salone delle sculture lapidee, with its view across the roofs of Siena — his art returns, in effect, to the house of the language it translated.

His Sienese credentials need no embroidery. Of the three cornerstones on which the specialist literature rests the knowledge of his sculpture, two are Sienese — the signed relief in the Oratory of San Bernardino and the decoration of the unfinished Duomo Nuovo, which he directed from 1340 until the works’ suspension around 1348 — and the third, the Tarlati chapel of 1334 in Arezzo, reaches back to Siena all the same through the Vallepiatta portal, as the section on the Duomo Nuovo sets out.

That interrupted cathedral is the gravitational field of everything Giovanni made in Siena, and its dispersal explains why the visitor must hunt him across the city rather than find him in one room. The statues and Christ in Majesty of the Vallepiatta portal survive as originals in the Museo dell’Opera; the signed relief keeps its oratory; small figures and a Prophet’s half-figure inhabit the cathedral itself; the tabernacle from Sant’Eugenio a Monistero stands in the chapel of Palazzo Chigi Saracini. The Pinacoteca is one station of this city-wide scatter — the youngest, in fact, and the sections that follow treat the pieces it shelters as Sienese chapters of a corpus that runs from Arezzo to Volterra to Cleveland.

One guest, at least, is certain and recent. In 2021 the Ministry of Culture acquired for the Pinacoteca a medieval marble Head of a Bishop by Giovanni di Agostino, presented to the public by Roberto Bartalini and Elena Rossoni — a significant event twice over. It set an autograph-quality physiognomy from the sculptor’s orbit into the national collection, a mitred head to weigh against the episcopal faces of his documented decade, from the Tarlati ambient to the Pistoia years; and it did so under the sponsorship of the scholar whose studies have done most to define the two Agostini, father and son, as distinct artistic personalities. What monument the head once crowned — a tomb, a portal, a shrine — is a question the sources consulted leave open; an isolated head is by nature a fragment in search of a body, and the Volterra fragments show how eloquent such searches can be.

The deeper reward of the Pinacoteca, however, is comparative, and it is available in no other building on earth. One floor away from the sculpture hall hang the paintings of the very decade in which Giovanni’s manner formed: Ambrogio Lorenzetti’s Annunciation of 1344, Simone’s narratives, Pietro’s enthroned Virgins. The visitor who walks from the Lorenzetti rooms to the marbles performs, in ten minutes, the experiment on which a century of criticism rests — measuring the sculptor’s graduated projection, his incised distances and breathing grounds, against the painted space that fed them. Elsewhere the rilievo pittorico must be argued from photographs; here it can be tested against its sources across a staircase. The Pinacoteca is not merely a repository of Giovanni’s work: it is the laboratory of his definition.

A word of method. The sculpture hall is a recent arrangement in a museum that has undergone long campaigns of restoration and rehanging, and displays move; the full checklist of pieces attributed to Giovanni currently on view is stated here only as far as the documentation warrants, and no complete checklist is attempted. The attributions themselves, as everywhere in this corpus outside the one signed relief across town, are argued rather than documented — proposals of the critical literature, adopted with their authors named — and the reader will find each section declaring its evidence, its doubts and its dimensions, or the absence of all three, in the usual way.

What is not in doubt is the fitness of the setting. Giovanni di Agostino spent his maturity trying to raise, beside the old cathedral, a building his city could not finish; the plague closed the yard, and the fragments of his intention have been migrating into museums ever since. That the youngest of those museums to receive him is Siena’s gallery of painters is a kind of historical justice: the sculptor who spent twenty years teaching marble to behave like painting has ended, at last, among the paintings — a guest, but one the house was always waiting for.

A Madonna in the Making: Design and Accident in the Pinacoteca’s Marble

The first work of the Pinacoteca group is also the strangest object in the whole corpus: a Madonna who is fully present as a design and almost absent as a surface. The tall, narrow slab hangs on its modern bracket like a page torn from a sketchbook and enlarged to life — a standing Virgin and Child in high relief whose composition can be read at a glance and whose skin, everywhere, refuses the eye the finish it expects. Whether that refusal is the sculptor’s interruption or the centuries’ erosion is the question that must be held open to the end; what is certain is that no other piece attributed to Giovanni di Agostino shows so nakedly what one of his figures looks like on the way to becoming itself.

The scheme is the classic Sienese standing Madonna, and it declares itself through the ruin. The Virgin rises the full height of the slab, veiled, her weight gathered in a long frontal column; her head — the most resolved zone of the entire relief — inclines to her left, toward the Child she carried on that arm, the veil framing a small oval face with recessed almond eyes, a short nose and a pursed mouth, the gaze lowered in the direction of the infant. The head approaches, without quite reaching, the soft finish of the corpus’s other Virgins; below it, resolution drains away by degrees — torso roughed, forms blocked, the drapery’s architecture drawn but unskinned — until at the base the marble is little more than organized rock above a plain rough plinth.

The Child is the relief’s wound. The slab’s upper right corner has broken away — the modern mount’s dark clamp sits in the scar — and the break has taken most of what a Madonna exists to hold: the infant’s head, which her inclined cheek still leans toward, survives at best as an abraded mass, and His body reads as a diagonal of roughed forms across her left side. What endures, with unexpected clarity, is a bent leg — a chubby thigh, a knee, a small foot — swinging free at the level of her hip, the one passage where the Child’s livingness escaped both chisel’s silence and stone’s loss. The group’s tenderness must now be reconstructed from vectors rather than faces: her bowed head, His kicking leg — a mother’s attention bent over the memory of a child.

The lower half, read closely, settles one thing: the design was finished even if the surface was not. The fold system is complete — long diagonals sweeping down from the clasping right arm, a deep channelled S-fold hollowing the right flank, the hem swinging into curling pockets above the base — the very “rivers” of drapery that the Montepulciano font’s stem and the Volterra gisant present in their polished, final state, here left as riverbeds without water. Over everything lies the evidence of hard history: chalky abrasion, chipped arrises, and a rust-yellow stain bleeding down the right side where iron once touched the stone — a fitting’s tear, staining the marble like the memory of the clamp.

And so to the question the object itself poses: unfinished, or weathered? The arguments do not all point one way, and they are stated fairly here. For weathering speaks the corpus’s own precedent — the Volterra presentation Madonna, eroded to a ghost by her decades over the Bishop’s Palace doorway, proof that exposure alone can strip a finished Sienese marble to roughness. For interruption speaks the differential itself: erosion attacks a figure broadly, but here the finish falls off in an ordered gradient, head to hem, exactly as a carver’s work proceeds — the face carried furthest, the body blocked behind it, the base barely opened. The most economical reading, offered here as a reading, is both at once: an abbozzo — a figure caught between the punch’s roughing and the file’s skin — that afterwards suffered exposure, breakage and staining; a work interrupted first by the workshop and then by the world. Only examination of the tool-marks, claw against weather, can take the question further.

If the slab is indeed an interrupted carving, history supplies a frame almost too apt to resist — and it is labelled here plainly as inference, since the sources consulted publish no provenance for the piece. Giovanni di Agostino’s Sienese maturity was spent as capomaestro of the Duomo Nuovo, the colossal cathedral enlargement whose yard the plague years closed around 1348, leaving walls, portals and — necessarily — workshop stock suspended mid-gesture. An unfinished Madonna in his manner, in Siena’s own gallery, invites the thought that it is a splinter of that stopped yard: a figure abandoned on its bench when the city’s greatest project died, the sculpture interrupted as the cathedral was interrupted, perhaps in the same season and by the same catastrophe. The hypothesis explains everything and is documented by nothing; it stands here as the natural conjecture, awaiting a published pedigree.

Within the corpus the piece converts its misfortune into instruction. Giovanni’s Madonnas can be followed across their whole lives — the signed relief of San Bernardino across town, the Louvre Virgin from the Arezzo dispersal, Volterra’s weathered mother with her standing Child — and this one alone is caught unborn, the only place where the method behind those finished surfaces lies open: the stages of punch and claw whose endpoints are the polish of the Arezzo Jordan and the drilled shadow-dots of the Volterra beard. There is even a sense in which the slab literalizes the master’s deepest formal idea. His pictorial relief is an art of figures emerging by degrees from a responsive ground; here a figure is emerging from the ground in earnest, arrested at the very threshold his finished works dramatize. The temptation to read the stone through Michelangelo’s non-finito must be declined — for the Trecento, an unfinished surface was an accident, not an aesthetic — but the accident teaches what no finished work can: how much of this sculptor’s tenderness was already present in the block before the last tools ever touched it.

A note on condition and caveats follows. The state is as described — differential finish, general abrasion, the upper right corner lost with most of the Child’s head, iron staining at the right, the modern bracket intrusive; the attribution to Giovanni di Agostino rests on the museum’s designation and the piece’s evident citizenship in his formal world, without a document; neither dimensions nor provenance are published in the sources consulted, and both remain to be established. What needs no establishing is the object’s peculiar eloquence. Every other work discussed here has a surface the sculptor released; this one has a surface he never signed off — a Madonna forever halfway out of the marble, her head already bowed in love toward a Child the stone had not yet fully given her, and now never will.

Gesture and Sacred Presence in Giovanni di Agostino’s Christ Blessing

The Christ Blessing gives the Redeemer as a presence reduced to three things: the face, the raised right hand and the enveloping drapery. The figure is frontal and broad in the shoulders, the head rising above the garments with a restrained dignity, and authority is conveyed by stillness and proportion rather than by movement. The single gesture, the hand lifted before the chest with its fingers gathered into a compact, carefully articulated shape, is the point at which presence turns into address. Asymmetry keeps the frontality from stiffening: the raised arm interrupts the mass of the torso, and the folds cross the body in unequal directions, leading the eye between hand and face, the two centres of the devotional meaning.

The head is long and narrow, framed by hair that falls toward the shoulders, the beard articulated in a sequence of softly cut locks. The brow, the narrow eyes and the slightly parted lips give an expression that can be read as solemn and contemplative, and the gaze is directed up and away rather than at the beholder, which leaves the naturalistic face a measure of distance. The modelling passes from cheek to forehead without abrupt transitions, though part of that softness must be the condition of the surface. The mantle falls from the shoulders and gathers across the lower torso in broad folds that make a base for head and hand, while the sleeve round the raised arm swells into a substantial curved volume that keeps the hand from seeming detached.

The natural terms of comparison are Giovanni’s other blessing Christs: the half-length Redeemer in the gable of the Tarlati chapel, the Christ of the Volterra tabernacle fragments, the Christ of the Vallepiatta lunette. The Pinacoteca gives the piece to Giovanni and dates it about 1340; it comes from San Domenico in Siena. Nothing more is known of its setting, and the irregular lower edge should not be taken to prove that it was made as an independent bust: it is a fragment whose original architectural or sculptural frame cannot be reconstructed from the marble alone.

A note on condition and caveats follows. The surface is discoloured and abraded and the fingers are softened; three small round openings toward the lower right may be fixing holes or traces of restoration, but only technical documentation could say which; no dimensions are published in the sources consulted. The attribution rests on the museum’s designation and on style, not on a document, and is given here as an attribution.

The Sword as Cross: Saint Galgano in Sienese Gothic Sculpture

The relief shows the episode on which the legend of Saint Galgano turns: the knight who plants his sword in a rock, so that the weapon becomes a cross before which he can pray, and renounces the world for the hermit’s life. The accounts differ in their details, but all tie the miracle to his conversion, and the sculptor has reduced the story to what it needs: a single figure, an inclined head, a hand on the hilt, a blade that descends into the rock. The field is a tall rectangle inside a heavy stone border; Galgano fills nearly all of it, the rock takes the lower left corner, and foliage in the upper corners stands for the open air.

The figure is built from gentle changes of direction. The head bows toward the sword, the shoulders set an oblique axis, the arms describe a loose curve across the torso, and the long garments fall to the foot that projects at the bottom of the relief, a small suggestion of a stride interrupted. The hand on the viewer’s left rests over the hilt and the other gathers the mantle at the centre of the body; below them the folds deepen into elongated hollows that guide the eye down and back to the blade. Galgano is a beardless youth with waving hair, and the elegance of his hair and dress survives in the act of renunciation, so that the knight he was remains present in the image of the convert.

Space is compressed but graduated. Head, arms and gathered cloth project furthest; the foliage keeps close to the ground and is deepened by drilled hollows that make points of shadow; and the modulation of relief to organize spatial relations is the “painterly” conception that Bartalini places at the heart of Giovanni’s practice. The flowing silhouette and the delicacy of the hands recall the linear grace of Simone Martini, but that, as for the San Bernardino relief, is a comparison of visual culture and not a documented contact.

The Pinacoteca dates the relief to 1335–40 and records it as coming from the church of Santa Lucia at Poggibonsi. Its attribution to Giovanni rests on that designation and on style, and it is not beyond question: an article by Kreytenberg of 1993 on Agostino and Saint Galganus shows that the subject has also been discussed in connection with the father, and the relief is accordingly given here as an attribution. Its original function, whether within an architectural arrangement, as devotional furnishing or as part of a larger ensemble, cannot be established from the marble and the catalogue data available.

A note on condition and caveats follows. Grey veining crosses the pale marble and must be distinguished from carved contours and from damage; wear and local discolouration soften the face and the sword; no dimensions are published in the sources consulted.

The Apostle’s Presence: Gesture and Drapery in Saint Paul

The Saint Paul is a figure of concentrated authority, frontal in body with the head turned toward the viewer’s left, as though attending to something outside the field. The turn suggests that the figure once belonged to a larger arrangement, directed at another sculpture or at a central sacred image, though that remains a compositional hypothesis. The face is marked by a prominent brow, a long nose and a full beard whose curling strands descend over the chest in a pointed mass, the most worked passage of the piece; the hair lies close to the crown before loosening into locks at the sides. The turned head lets brow, cheek and nose form a stronger profile than a strictly frontal pose would, and the shadow round the eyes gives an impression of watchfulness, though the surface is too worn for a precise reading of the gaze.

The mantle supplies the structure. It descends from the shoulder on the viewer’s right and crosses the torso in broad, overlapping folds, open across the chest and converging lower down into diagonal and pointed formations; raised ridges catch the light and deeper recesses beside them cast shadow. The contrast between this large drapery and the small curling forms of the beard fixes the hierarchy of the figure, bodily weight below and identity and attention above. On the viewer’s left the lowered hand is visible, and beside it, at the lower edge, a beaded rectangular object that the caption does not identify. The figure is called Saint Paul on the museum’s designation, and the attribute that would confirm it, the sword of his martyrdom or the book of his letters, cannot be read with certainty from the surviving forms; the hand on the opposite side is less legible still.

The figure ends at an uneven lower edge with no feet and should be read as incomplete. The Pinacoteca dates it to the first half of the fourteenth century and reports a provenance from Sant’Agostino in Siena, which by itself establishes neither the original placement nor the function. The attribution to Giovanni rests on the designation and on style, and is given here as such.

A note on condition and caveats follows. Grey veining crosses the head, torso and drapery; it is natural and must not be mistaken for carved lines, fissures or repairs. Surface wear and losses affect the hands and the face. No dimensions are published in the sources consulted.

Grosseto, Pistoia, Montepulciano: The Workshop on the Road

The Grosseto portal raises the same kind of unresolved workshop attribution. Siena secured lasting control of Grosseto in 1334, and according to the Dizionario Biografico the jambs and lintel of the portal on the south flank of the cathedral were made in the immediately following years, 1335–36, together with the neighbouring window and its sculpture of Sienese origin. Before discussing authorship, an important material distinction must be drawn, because popular descriptions rarely make it. The architrave is genuinely fourteenth-century: it shows the Redeemer frontally between busts of Luke and Mark in three-lobed frames, with Matthew and John at the ends, separated by spiral foliage. The rest of what the visitor sees, however — the arch zone, the lunette group with the enthroned Virgin and Child between angels, the statues at the sides — is a completion of 1897 in period style. The portal is thus part Trecento and part nineteenth-century neo-Gothic, and any stylistic argument must confine itself to the medieval architrave.

On the question of who carved that architrave, the sources disagree. Kreytenberg is categorical: “il ruolo determinante fu chiaramente del padre e non di G.,” the determining role clearly belonged to the father and not to Giovanni; he points to the resemblance of the figures and heads to those on Agostino’s tomb of Cino da Pistoia, and adds that no careful study has yet defined Giovanni’s share. The Enciclopedia dell’Arte Medievale entry on Agostino reports two earlier views, one seeing in the cathedral the joint workshop of Agostino and Giovanni with the probable presence of Agostino’s own hand, another, advanced orally, giving Agostino the south window and portal. A local historical atlas, by contrast, assigns the architrave to “Giovanni d’Agostino e bottega,” Giovanni and his workshop, while regional tourist literature speaks vaguely of “followers of Giovanni d’Agostino.” The balanced conclusion available on present evidence is that the Grosseto south portal is a product of Agostino’s workshop of the mid-1330s, probably with Agostino himself in the leading role, and that Giovanni’s share remains undetermined. Nothing in the sources consulted supports the notion, occasionally encountered, of a Grosseto cathedral façade designed by Giovanni.

In the later 1330s the attributed corpus of the workshop reaches Pistoia and Montepulciano. At Pistoia, Agostino was engaged on the tomb of Cino de’ Sighibuldi in the cathedral, commissioned on 11 February 1337 and carved in about 1337–39; in Kreytenberg’s reading, Giovanni was meanwhile at work in the same building on the tomb of Bishop Atto. At Montepulciano, only the basin of the cathedral font, with its three reliefs of the Baptism of Christ, is given to Giovanni, while its three supporting figures are assigned to Agostino on the strength of their closeness to a Madonna and Child enthroned from Montepulciano now in the Staatliche Museen in Berlin. Around these poles the encyclopedic literature groups a number of frankly collaborative products, works in which Giovanni’s role appears “preponderante,” preponderant, but in which Agostino’s share is “quanto mai difficile da identificare,” exceedingly difficult to identify: among them a Petroni family funerary chapel front dated 1336 in the cloister of San Francesco in Siena and the Ricciardi reliefs in Pistoia. The lunette of the portal of San Francesco in Siena, dated 1336 and showing the Madonna and Child with Saint Francis, the Blessed Pietro da Siena and the Annunciation, is referred “forse,” perhaps, to Agostino.

A Chair of Law Beneath a Gothic Canopy: The Tomb of Cino dei Sighibuldi

When Cino dei Sighibuldi — the name appears in the sources also as Sinibuldi and Sinibaldi — died at the close of 1336, Pistoia lost the most famous of its citizens: jurist of European authority, whose Lectura on Justinian⁸’s Code shaped a century of legal teaching, and poet of the dolce stil novo, correspondent of Dante and mourned in verse by Petrarch. The commune’s answer was this monument in the cathedral of San Zeno, today against the wall of the right aisle: not a knight’s tomb nor a prelate’s, but something rarer and more modern — the tomb of an intellectual, in which the deceased appears neither armed nor recumbent but at work, teaching, twice over, in relief and in the round. Among the professors’ tombs that Trecento Italy invented for its universities, from Bologna northward, the Pistoia monument is the most ambitious to survive in Tuscany, and it carries with it an attribution history that leads directly into the Sienese workshop of Agostino and Giovanni.

For once the documents are generous, and they frame the work precisely. The commission was awarded on 11 February 1337, within weeks of Cino’s death, and the final payment followed on 27 December 1339; the contractor named in the allogazione is Cellino di Nese, a Sienese master otherwise known at Pistoia as builder of the Baptistery. From that parchment a long equivoco was born. Vasari, characteristically, had given the monument to Andrea Pisano; the rediscovery of the contract in the mid-nineteenth century put Cellino’s name in his place; but when the document was republished in 1903 its editor observed that Cellino figures there as accollatario — the undertaker of the enterprise, its guarantor — and that the carving itself, executed in Siena, must belong to an unnamed Sienese sculptor. It was Adolfo Venturi, in 1906, who identified that master as Agostino di Giovanni, and the proposal won the assent of the leading connoisseurs of the following half-century.

Enzo Carli’s close analysis of 1966 refined rather than overturned it: the bulk of the monument is Agostino’s, but in certain figures — including statues once flanking the central group — Carli sensed a second, subtler and more restless hand, which he thought might be Agostino’s other sculptor son, Domenico. Roberto Bartalini’s study of 2002 in “Prospettiva” now anchors the monument in the modern reconstruction of Agostino’s career. The captions therefore carry the name of Agostino di Giovanni, as the prevailing specialist view has it. The minority reading, which gives the monument to the son and is met in local guides, rests on the circumstance that it was carved in Siena in 1337–39, inside the family workshop, in the years when Giovanni was back in his native city, and not on any document naming him. One ghost of the older literature, by contrast, should be dismissed on sight: the pairing “Agostino di Giovanni and Agnolo di Ventura,” repeated from the Arezzo partnership into contexts where no document supports it.

The architecture reads as a biography in three registers. At the base, four foliate corbels carry the sarcophagus out from the wall; upon its lid stands the free-standing group of the master among his pupils; and over the whole rises a canopy of two spiral columns with leafy capitals, supporting a broad arch whose inflected, keel-like profile is fretted inside with a cascade of cusps — a piece of flamboyant drawing rare in Tuscany at this date — closed by a cornice on which sits a gabled and pinnacled aedicule with its own company of statues. The programme ascends accordingly: the labour of the school below, the living magisterium in the middle, and at the summit the heavenly court to which the dead man is commended. It is the same microarchitectural intelligence — the monument as a small building, the figures lodged in it like relics — that governs the Tarlati cenotaph at Arezzo, here compressed into the format of the professor’s tomb.

The sarcophagus front is the monument’s most celebrated invention: a continuous lecture hall in low relief, framed between panels of climbing foliage and sealed above by a dentilled cornice. At the left Cino sits in profile at a tall Gothic cathedra, a double-sloped lectern before him, his lesson in progress; toward him lean two benchfuls of scholars at sloping desks, some following the text, some writing, heads bent or lifted in that unidealized variety — hoods, caps, bald crowns — which makes the scene feel reported rather than composed.

At the right a figure stands beside a door with a pierced quatrefoil panel, the threshold of the school, as if arriving late or keeping it. Ottocento sentiment embroidered the scene with names, as the discussion of the sarcophagus relief below recounts; what the relief itself insists on is humbler and grander: the school as such, the transmission of law as a civic liturgy worthy of a tomb.

On the lid the lesson is promoted to the round. Cino, at larger scale, sits enthroned at the centre in the doctor’s hooded cap, his left hand steadying the book, his right raised in the disputational gesture, fingers ticking off an argument; before him rises a small colonnette with a foliate capital, the support of his lectern. Four smaller disciples flank him, two to a side, gowned and hooded, clutching their books and scrolls, faces turned toward the master. The group bears the scars of the monument’s wanderings and was once larger, as the discussion of the group below details.

The crowning aedicule turns the monument from school to heaven. Within its four-columned tabernacle, beneath gables and a spire, sits the Virgin with the Child on her arm between two standing saints; the descriptive record identifies them as James the Greater and Zeno — the twin patrons of Pistoia and of this cathedral — with a small kneeling devotee, the dead man himself, presented at the Virgin’s side. Recent scholarship on the workshop has noticed that this formula, the city’s patron saints occupying the tomb’s aedicule, is precisely what makes the Pistoia monument a model for reconstructing related Sienese tombs elsewhere. The civic logic is exact: the commune that paid for the tomb places its own heavenly protectors in charge of its citizen’s soul, and the professor who spent his life expounding earthly law is delivered, at the summit of his monument, to the jurisdiction of grace.

For the purposes of this essay the monument is the indispensable term of comparison for the pictorial relief of the son, even though it is generally given to the father. Executed in Siena in 1337–39 — exactly the years when the young Giovanni di Agostino, between his two spells as capomaestro, was back in his native city — it shows, on the prevailing reading, Agostino’s art at its most open: the recent literature observes that here the old master softens, admitting something of his son’s fluency of rhythm, yet without surrendering his fundamentally structural conception, the figures aligned as solid volumes against a flat, abstract ground. Set the sarcophagus relief beside Giovanni’s work of the same years and the two poetics declare themselves: Agostino builds his school out of discrete plastic blocks, clear-edged and countable; Giovanni, in the manner the critics call pictorial, would have graded the projections atmospherically, letting figure melt toward ground. And if Carli was right that a subtler hand — perhaps Domenico’s, formed on Giovanni’s example — touched the flanking statues, then this one monument becomes the place where the three manners of the family workshop can be triangulated within a single frame.

The tomb’s later history is written on the wall around it. A small plaque at the lower left, partly visible in the view of the sarcophagus relief below, records that the monument was “transferred here for greater decorum,” and that on 17 June 1960 the exhumed bones of Cino were honourably placed within the urn — the moment at which a cenotaph, six centuries on, became a tomb in earnest. Below, a framed epitaph in Roman capitals, plainly a post-medieval addition of unverified date, gives the humanist summary: to Cino, eminent interpreter of the law and teacher of Bartolus, the people of Pistoia made this for their most worthy citizen; he died in the year of Our Lord 1336. The marble itself, patinated and chipped, with its stucco hand, wears its displacements openly; the sources consulted publish no overall dimensions, and the full itinerary of the monument’s moves within the cathedral is not recovered here. None of this diminishes the whole. Among the tombs of Trecento Tuscany this is the one that buries neither a warrior nor a saint but a mind at work — and the Sienese workshop of the Agostini, father and son, gave that idea its lasting form.

Five Figures and a Lesson: Cino in Cattedra

Raised on the lid of the sarcophagus, framed between the canopy’s vine-wreathed spiral columns, this group of five figures is the heart of the Cino monument and one of the boldest inventions of Trecento funerary sculpture: the dead man not recumbent but in session, teaching in the round, his class assembled about him in perpetuity. The documents that frame the whole monument frame this group too; what the detail image adds to them is the thing itself: five blocks of marble against the bare ashlar of the aisle wall, organized into the most durable image of medieval teaching that Tuscany possesses.

The iconographic gamble deserves to be measured first. The scene of the master in cattedra among his pupils belonged, by the 1330s, to the repertory of the professors’ tombs of Bologna — but there it lived in relief, a picture carved on the front of a chest, exactly as it does on the sarcophagus below this group. To repeat the subject a second time, promoted from relief to free-standing statuary, is the Pistoia monument’s own idea, and it changes the meaning. In relief the lecture is a memory, a narrated episode of the life now ended; in the round it becomes a present tense. The seated Cino is not shown as he taught but teaching, here and now, above his own bones, to students who will never graduate; the tomb converts the classroom into a liturgy and the professor into something approaching a cult image — enthroned, frontal, at twice his listeners’ scale, exactly as a Madonna sits among her saints. That scale, it should be said plainly, is hierarchy and not error: the medieval eye read size as rank, and the monument ranks wisdom.

The master himself is the most memorable presence. He sits robed in the doctor’s gown, a shoulder-cape with a dagged edge across the chest, his head wrapped in the hooded cappuccio whose lappet falls along the cheek — the uniform of the law faculty rendered with a tailor’s precision. The face under the hood is the sort of thing that tempts the word portrait: long and furrowed, heavy-lidded, the nose strong, deep folds bracketing a wide, thin mouth that hangs slightly open, caught between syllables, the gaze pitched up and over the heads of the audience in the manner of a man addressing a hall rather than a person. Whether any true likeness survives in it cannot be proven — no authenticated image of the living Cino exists to compare — but the commission followed his death by weeks, in a city where his features were common knowledge, and the sculptor has at the very least refused every convention of idealized age. This is a specific, tired, formidable face; if it is invention, it is invention of a naturalistic order rare in 1337.

The image also lets the eye perform a little material philology. The raised right hand, its fingers spread in the disputational gesture — the enumeration of an argument, point by point — is not the trecento marble but the stucco remake recorded in the conservation literature, replacing an original broken during the monument’s displacements; at close range the seam at the wrist and the slightly alien surface of the hand betray the substitution. Before the master rises a small colonnette, its plain shaft crowned by a leafy capital. What it carried, if it carried anything, can only be inferred — a lectern or bookrest is the natural reading, completing the cathedra ensemble with the open text of the law — and the inference should be labelled as such. Meanwhile the left hand, original, steadies the book upon his knees, though the colonnette hides it from this viewpoint: even mutilated, the group keeps both poles of the jurist’s craft, the written authority and the spoken gloss.

The four students repay individual attention, for the sculptor has taken care that no two are alike. At the far left stands the eldest, hood up, a short cape over his gown, a small volume clutched to the chest, the face drawn and attentive; beside him the liveliest of the four lifts his head sharply toward the master, lips parted, both hands hugging his book like a satchel — the very image of the pupil straining to follow. Across the colonnette, the inner right figure is the youngest, round-faced beneath a close cap, an unrolled scroll spilling diagonally from his left hand as though notes were in progress; and at the far right a hooded, mantled figure holds an open book at the waist, his shadowed face turned toward the master. Heads and gazes point in different directions, and books and scroll mark reading, transcription and attention: the little company orchestrates the whole economy of the schoolroom — attention, transcription, study, endurance — around the single speaking figure. Their gowns fall in the same prismatic troughs as the master’s, but at their reduced scale the folds read almost as fluting, turning each student into a small column of cloth.

Yet the class we see is an edited one. The conservation record is explicit that two further statues once stood at the sides of this group and have been removed to the cathedral’s Museo Capitolare — the very figures in which Enzo Carli, in 1966, detected a hand subtler and more restless than Agostino’s, plausibly that of his other sculptor son Domenico, formed on the example of his brother Giovanni. The present five-figure symmetry, two disciples to a side, is therefore a modern state, not the trecento one; the original company was larger, its rhythm different, and any stylistic judgment passed on the ensemble must remember that its most debated members are absent. The group photographed here is, in the philologist’s sense, a text with lacunae — coherent, but shorter than what the workshop delivered in 1339.

Read as style, the detail is, for the prevailing literature, a manifesto of Agostino di Giovanni’s art in its maturity — the reading these captions follow. Each figure is conceived as a closed plastic volume, clear-edged, countable, set against the flat abstract ground of the wall with no atmospheric mediation — the “structural” conception that the critical literature opposes to the pictorial relief of his son Giovanni, who in these very years was grading his marble surfaces so that figure melts toward ground. And yet the group also shows the old master flexing: the recent literature on the workshop finds precisely in the Cino monument an opening toward the son’s softer rhythms, and it can be felt here in the ease of the students’ turned heads, the fluency of the lappets and hems, the loosened fall of cloth over the master’s knees. Here the comparison is the point: set this group beside Giovanni’s San Bernardino relief and the two poetics of a single household stand face to face — the father building bodies, the son dissolving grounds.

Condition, finally, is legible and honest. Beyond the stucco hand, the marble carries the chips and abrasions of six centuries and at least one transfer, with the patina pooling in the fold-troughs and the drill-shadows of the hoods; no dimensions for the individual figures are published in the sources consulted here. None of it obscures the group’s authority. Among all the ways the Trecento found to deny death — the recumbent knight, the praying donor, the soul borne aloft — this is the most humane and the most audacious: a man simply continuing his work. The lesson has been in progress since 1339; the students have not yet looked away.

Nine Students and a Chair of Law: The Sarcophagus of Cino dei Sighibuldi

If the statue group on the lid gives the Cino monument its icon, the sarcophagus beneath gives it its story: a continuous classroom in low relief, running the whole length of the chest between panels of climbing foliage, beneath a dentilled cornice, above the acanthus corbels that carry the tomb out from the wall. The relief belongs to the same documented campaign as the rest, and it is carved on two slabs whose vertical seam is still legible a third of the way along the field. Its subject is the plainest imaginable and, for a tomb, the most radical: not a miracle, not a funeral, not a soul ascending, but a lesson in progress, with the furniture included.

The genre has a precise pedigree, and Cino’s own biography makes the choice pointed. The theme of the master lecturing to his scholars, carved on the arca itself, was born on the glossators’ tombs of Bologna in the later Duecento — one of those mausoleums is reckoned the first monument anywhere to show the professor in session on his own sarcophagus — and it would become classic in the tomb iconography of the university world. Cino was a son of that world twice over: trained at Bologna in the 1290s, doctored there in 1314, sharpened at Orléans on the new dialectic, and celebrated ever since as the great renovator of Italian legal science, the initiator of the school of the commentators, who taught at Siena, Perugia and Naples with the young Boccaccio among his hearers. When Pistoia buried him, it reached for the Bolognese formula of the teaching tomb and had it executed by a Sienese workshop — transplanting the iconography of the studium into a Tuscan cathedral, and then, uniquely, doubling it in the statuary above.

The composition reads against the usual grain, and the choice is expressive. The master sits not at the centre but at the far left, in profile, so that the whole class flows toward him and the visitor’s eye, moving left to right, travels through the school before reaching its door. Cino occupies a panelled cathedra whose base is pierced with little trefoil arches, before a tall lectern with a double-sloped top raised on its own stem — a reading-desk rendered with a joiner’s exactness — his hands busy at the book upon it, his hooded head bent to the text. He is barely larger than his students: on the chest, unlike the lid, hierarchy yields to reportage, and the professor is simply the first workman in a room full of them.

Then comes the first desk, and with it the relief’s quiet genius for variety. Two scholars sit behind the long sloped board: one, capped, bows over the open volume, following the letter; his neighbour, hooded, lifts his head sharply toward the master, mouth caught open — the eternal student interrupting with a question, or straining after a difficult passage. A third sits lower on the near side of the desk, turned in profile with an open book on the lap, wrapped in a soft fall of hood that the nineteenth century, as the passage below tells, found irresistibly feminine. The desk itself deserves its own sentence: a broad inclined plane on trestle supports with trefoil-cut feet, books propped upon it — the standard equipment of the Trecento lecture hall, carved as lovingly as the people.

The second, longer desk seats six, and together they form a small taxonomy of attention. At its left end a young man in a cap plants his hands on the board, all eagerness; beside him a second raises a hand to his breast in the gesture of disputation, arguing back; then comes the relief’s most human touch, a pair of heads bent close together, one student turning to confer with the man behind him — the whispered aside that every lecturer has endured; a further figure pauses, hand lifted as if to the chin, weighing what he hears; and at the row’s end a deeply hooded elder holds a small book up before his eyes, reading on regardless. Depth throughout is managed by overlap alone — heads lapping heads in the second rank — against a ground kept resolutely flat; the descriptive literature’s own phrase for it, figures standing out “on a flat ground,” names exactly the structural economy that the literature identifies with Agostino’s relief style.

The right end closes the scene like a colophon. A figure stands apart, in profile toward the class, hands joined before him around a small object whose identity the image does not settle — book, tablet or the roll of the school have all been proposed by the eye, and the question is left open here — beside a wall pierced by a quatrefoil opening and a miniature Gothic portal with pinnacles: the door of the school, no less carefully carpentered than its desks. Custodian, beadle or latecomer, he marks the threshold between the lesson and the world. The framing completes the object: at either end of the chest a narrow panel of rising foliage — a flowering branch at the left, and at the right a sinuous stem whose tip appears to curl into a serpent-like head, an observation offered with due caution — while on the fascia above, faint scratched numerals are legible in raking light, plausibly assembly marks from one of the monument’s documented transfers, though this too remains an inference from the image.

Around this sober scene the nineteenth century wove its romances, and they should be enjoyed and then set aside. Old image captions identify the hooded figure at the desks as a woman and gloss her as a personification of Roman Law; the same tradition found the young Bartolus of Sassoferrato among the pupils and, in the statue group above, even Selvaggia de’ Vergiolesi, the beloved of Cino’s lyrics — this last doubly fragile, since the scholarship on the poet warns that “Selvaggia” may be no historical woman at all but a senhal, a code-name of the courtly game. Of all these only the Bartolus connection has old footing, enshrined in the later epitaph below the monument, which styles Cino “teacher of Bartolus”; the marble itself names no one. Its true documentary wealth lies elsewhere, in the things: the sloped trestle-desks, the propped and lap-held books, the panelled cathedra and stemmed lectern, the very door of the school — as complete a sculpted inventory of the Trecento classroom as Italy possesses.

A last word on afterlife and condition. The descriptive literature records that in 1624, during works on an altar’s foundations in the cathedral, bones identified as Cino’s were found and laid beneath this cenotaph; the plaque partly visible at the lower left of the image closes the story, recording their honourable translation into the urn itself on 17 June 1960 — three centuries in which the classroom relief stood over a grave that slowly became real. The marble is chipped at the frame edges and warmly patinated, the seam between its two slabs open but stable; no dimensions are published in the sources consulted. On the prevailing reading this relief is the father’s answer to the son’s art: where Giovanni di Agostino melts figure into ground, Agostino builds a room out of aligned, countable volumes — and fills it, once and for all, with the ordinary noise of learning.

A Font Held Up by Apostles: The Baptismal Font of Montepulciano

After the black-and-white reproductions of the Volterra shrine, the essay returns to a living object photographed in colour and in use: the Trecento baptismal font of Montepulciano, standing at the centre of the first chapel on the left of the cathedral — the baptistery — against the most improbable of backdrops. Behind it stand a plain plastered wall and, above the rim, the little round-arched wooden door of the sacrament aumbry, aligned with the font by the photographer’s axis and belonging to the setting of Andrea della Robbia’s Altare dei Gigli of about 1512, whose glazed frieze lies outside the frame. The accident is a fair emblem of the object’s condition: a fourteenth-century font living inside a seventeenth-century church, beside a sixteenth-century altar, in an arrangement made in the nineteenth century — a palimpsest at every depth of the picture.

The attributional landscape must be laid out first, because three versions of it circulate. The authoritative modern position is that of the Dizionario Biografico entry on Giovanni — Kreytenberg’s — which reads the font as a divided work: the basin with the three reliefs of the Baptism of Christ is Giovanni’s, while the three figures that support it point to his father Agostino, standing close to the enthroned Madonna in Berlin; the font was under way in the same years as the Pistoia commissions, around 1337–39, and Giovanni did not carry it entirely to completion. The local tradition, by contrast, gives the whole to Giovanni — so the diocesan literature, which also names the most recent dedicated study, by Giorgia Scarpelli, and identifies the stem figures as the Apostles Peter, John the Evangelist and a third companion. And the guidebooks add a third name: the font “attributed to Giovanni di Agostino or to Tino di Camaino,” an alternative that the specialist literature on Giovanni does not entertain but that the visitor will meet on the page and occasionally on the wall. The caption proposed above follows the Dizionario’s division as the argued position, with the rest recorded here.

The object’s wanderings are documented with unusual precision. The font comes from the old Pieve di Santa Maria, the church the present cathedral replaced; during the new building’s long life it stood in an external chapel on the right flank of the duomo, now disused; and in 1816 Bishop Carletti converted the first left chapel — dedicated at the cathedral’s beginnings to St Thomas the Apostle, under Bellarmini patronage — into a baptistery and moved the font to its centre, installing beside it the two statues of St Peter and St John the Baptist that still flank the della Robbia altar, the Baptist’s scroll reading, aptly for the room, “I am the voice of one crying in the desert.” The ensemble the image shows is thus an 1816 composition of pieces from four centuries, and it is treated here as such.

The font itself is a chalice of architecture. The basin — polygonal, an octagon to judge from the five faces this viewpoint discloses — spreads above a chamfered underbowl, its walls framed by small consoles at the angles carrying a stepped cornice whose upper fascia breaks forward over each corner. The front face holds the Baptism: Christ frontal at the centre, standing in the Jordan rendered by the old convention of the heaped water-mound, its surface stirred into wavy strata that continue into the rocky bank at the left; the Baptist on the right bank in profile, bent toward him, his arm extended over Christ’s head with the arc of poured water — or the descending ray — curving down to the crown. On the far left face and on the end face at the right stand slender draped figures, presumably the attendant angels holding the garments, so that the Baptism unfolds, as the Dizionario’s phrase implies, across three reliefs rather than one; the faces flanking the Baptism itself carry vertical foliate motifs, and the faces continuing round the back escape this viewpoint and are left unclaimed.

The stem is the font’s theological wit. Three figures stand back to back around a central core, Apostles by the local identification — a beardless youth with long soft hair and a calm oval face, his mantle gathered across him, John the Evangelist by type; an older man with furrowed brow and short beard, a closed book pressed to his side, Peter or Paul by the same logic; the third turned away from the camera. Their hems overflow onto the round moulded plinth below, which sits in turn on a rough-hewn octagonal block, left rustic or replaced. Above their heads the core flares to meet a faceted collar under the bowl — and here the material itself performs: the grey veining of the marble streams down the flaring core in long liquid streaks, so that the stone appears to pour. On any other object this would be an accident of quarrying; on a font, where the basin above holds the water of the sacrament and the carved Jordan heaps around Christ’s body, the veins reading as water is an accident so happy that one hesitates to call it unintended.

Read against the Dizionario’s division of hands, the object becomes a family document — and a mirror-image of the Cino monument. On the Cino da Pistoia monument, carved in these same years, the father Agostino commanded the whole and the son at most hovered at the edges of the literature; here the arrangement inverts: the son takes the narrative, the father the figures. And the split is legible on the marble. The stem Apostles are built as compact plastic blocks, frontal, columnar, their drapery organized in strong simple masses — the structural manner associated with Agostino throughout; the basin’s Baptism, with its graduated projection, its landscape conventions, its figures sinking into and emerging from the relief ground, speaks the pictorial dialect that is Giovanni’s signature. Whether the division was a workshop economy, a succession, or simply the way a busy family firm met a provincial commission, the font preserves the two manners in a single object, load-bearer and storyteller, father under son.

Within the corpus the font also completes a specialization. It is Giovanni’s second baptismal font, after the one at Arezzo of the early 1330s whose Stories of the Baptist anchor the critical case for his pictorial relief; it is the third work of the accepted corpus to show the Baptist, after the Arezzo font and the Cleveland panel; and it is the second time the sculptor carved the Baptism of Christ itself for a basin of baptismal water — an artist repeatedly trusted with the sacrament’s own furniture, and repeatedly solving the same problem, how to carve the Jordan, with the heaped and striated water his Arezzo panels had already tried. On the Dizionario’s dating the font falls at the far end of the 1330s, contemporary with the Pistoia arca of Sant’Atto and just after the Ghini fragments — the mature edge of a career the Volterra shrine, if Kreytenberg is right, had opened at the decade’s start.

A note on condition and caveats follows. The cornice is chipped at the left front angle and worn along its arrises; the reliefs are abraded, with losses softening the Baptism’s detail; the rough base block may not belong to the original design; the rear faces of the basin and the third stem figure are unverified from this viewpoint; no dimensions are published in the sources consulted; and the attribution itself, as set out above, is a divided verdict rather than a document. What is beyond dispute is the invention’s fitness: a basin of sacred water carried on the shoulders of Apostles, the Church’s founders literally supporting the sacrament that makes Christians — while the marble’s own veins run down the stem like the Jordan escaping its basin, six hundred years of baptisms after the two Agostini, father and son, divided the work between them.

Two items that circulate in the popular repertory must be removed from Giovanni’s catalogue for want of any support.

The first is a supposed “signed lunette at San Francesco in Arezzo.” The research underlying this essay found no source for such a work — documentary, epigraphic or scholarly. The only signed work is the San Bernardino relief, which the museum literature itself describes explicitly as his “unica… opera firmata,” his only signed work; the San Francesco lunette actually discussed in the literature is in Siena, not Arezzo, is unsigned, and is tentatively given to the father.

The second is a “Madonna del Latte” attributed to Giovanni. No documented or broadly accepted work of that subject by him emerged from the research. One possible source of the confusion may be suggested, with the explicit caveat that it is a conjecture of this essay and not a documented fact: the Museo Diocesano in Siena, which houses Giovanni’s signed relief, also displays a celebrated painted Madonna del Latte by Ambrogio Lorenzetti, and the proximity of the two works under one roof could easily generate a conflation. Until the scholarly literature identifies a specific sculpture, no Madonna del Latte should appear in Giovanni’s catalogue.

The Cleveland Relief and the Problem of Father and Son

Among all the works associated with the name of Giovanni di Agostino, none exposes the instability of his catalogue more clearly than the marble relief of the Madonna and Child enthroned between Saints Catherine and John the Baptist in the Cleveland Museum of Art. The museum’s record attributes it to Giovanni, dates it circa 1340–50, and describes it as marble with traces of polychromy and gilding, measuring 70.5 by 52.5 by 5.9 centimetres; it entered the collection in 1942, accession number 1942.1162, as a gift in memory of Henry G. Dalton from his nephews, George S. Kendrick and Harry D. Kendrick. Nothing about the piece is documented — no contract, no payment, no recorded provenance from a specific building — and yet it has attracted some of the most eloquent prose in the entire critical literature on Trecento sculpture, precisely because everything about it must be argued from the carving itself. It is, depending on which of the two principal modern readings one follows, either the late masterpiece of the son on the eve of the Black Death or a work of the father: the perfect emblem, in a single slab, of the historiographical problem that has surrounded this family workshop since Vasari.

The first thing the image makes clear is how little this object behaves like a conventional relief. Within a plain rectangular frame, the upper register is given over to an openwork canopy of Gothic microarchitecture, carved entirely à jour: a taller central arch, cusped and crowned by a crocketed gable pierced with a trefoil, shelters the Virgin, while two lower cusped arches with their own crocketed gables shelter the flanking saints, the three bays divided and bounded by slender pinnacles bristling with crockets and finials. The ground behind this tracery is simply cut away, so that light passes through the marble and the canopy casts real shadows — the illusion of depth that Giovanni’s reliefs pursue through graduated projection is here achieved by literal perforation. At the apex of the frame a small projecting socle interrupts the upper edge; its purpose is not recorded, and whether it once carried a lost element or served the work’s original mounting must be left open. The whole upper zone reads as an aedicule in miniature, a portable echo of exactly the kind of canopied chapel architecture that Giovanni built at full scale in Arezzo in 1334, and the kinship between this carved tabernacle and the Tarlati aedicule is one of the quiet arguments in favour of keeping the relief within his orbit.

Beneath her arch the Virgin sits on a low, drapery-covered throne raised on an octagonal plinth, which rests in turn — a delightful detail easily missed — on two small crouching lions, the guardians of the Solomonic throne reduced to the scale of a goldsmith’s fancy. She is the elongated, small-featured Madonna of the Sienese ideal, her hair waving loosely beneath a light veil, her head inclined toward the Child who sits upon her left knee and twists outward with the springy, muscular vitality of a real infant, one hand catching at the neckline of her dress. Her left hand steadies him; her right, lowered along her side, is pierced by a drill hole through the closed fist — the unmistakable trace of a lost attribute, presumably a flower or stem once worked separately in marble or metal. The drapery is the true spectacle of the central group: the mantle pools over the throne and cascades down the plinth in deep, softly hollowed folds finished with carved fringes, the same textile delight that marks the signed relief in San Bernardino, and along these hems the surviving traces of polychromy and gilding, still faintly legible as darker accents in the image, hint at the chromatic richness the whole must once have possessed.

The two saints stand almost in the round within their bays, attached to the ground at only a few points. On the left, the young female saint — identified by the museum as Catherine — holds a book in her raised left hand and, in her lowered right, a fold of her dress; at her feet curves a toothed arc that reads most naturally as a fragment of her spiked wheel, which would confirm her as Catherine of Alexandria. On the right stands John the Baptist, instantly legible: gaunt and bearded, his hair falling in long ropes, his camel-hair tunic rendered as a shaggy carpet of fine strokes beneath the mantle, his legs and feet bare, the unrolled scroll of the “Ecce Agnus Dei” in his left hand while the right rises in the gesture of witness. The pairing of the Baptist with a virgin martyr around the enthroned Madonna is the standard grammar of the Trecento altarpiece translated into marble, and it is this translation — a painted sacra conversazione become sculpture — that has always tied the relief to the critical image of Giovanni as the sculptor who thought like a painter.

What the relief was made for can only be inferred. The museum proposes that it comes most likely from a Sienese church interior and that it is probably a fragment of a larger sculptural programme, such as a tomb, adding that it was probably completed just before the plague of 1348. All three “probablys” deserve to stand: the scale, the self-contained frame and the openwork carving would suit equally the upper zone of a wall tomb, a tabernacle or an altar ensemble, and nothing in the accessible record fixes its original setting. The date, likewise, is a stylistic estimate keyed to the presumed end of the sculptor’s activity, not a documented terminus. Readers of this site will recognise the pattern from the San Bernardino relief: in the corpus of Giovanni di Agostino, even the most admired objects float free of any document, moored only to the two fixed points of signature and contract.

It is precisely against the signed San Bernardino relief that the Cleveland marble has been measured, with results that could not be more opposed. For Bartalini, the “particolari effetti di vibrazione chiaroscurale e dunque valori ‘cromatici’” of Giovanni’s sculpture — its effects of chiaroscural vibration, its “chromatic” values — intensify steadily between the late 1330s and the early 1340s, and in this relief they reach their peak: “la delicatezza del modellato rasenta ormai il virtuoso: il marmo pare diventare una materia duttilissima, quasi del burro che lo scultore plasmi” — the delicacy of the modelling now borders on the virtuosic: the marble seems to become an utterly ductile material, almost butter shaped by the sculptor.

On this reading the Cleveland relief is the culmination of the “pictorial” manner, carved on the eve of the Duomo Nuovo’s collapse into plague and crisis. Kreytenberg deploys the very same comparison to the opposite end: set beside the signed Madonna, he argues, the Cleveland relief reveals its difference — the confrontation “fa risaltare chiaramente le differenze concettuali e artistiche fra le due opere, consentendo di attribuire il secondo ad Agostino,” it brings out clearly the conceptual and artistic differences between the two works, permitting the attribution of this one to Agostino, the father. The same stone, the same touchstone, two incompatible artists.

The museum’s own label, finally, requires the corrections that authority makes necessary. It gives the sculptor’s dates as circa 1310–1370, an end date repeated by the English-language reference literature; no document supports a death around 1370. The archival record of Giovanni ends on 27 June 1347, and the scholarly literature treats his death in the plague of 1348 as probable — the 1370 date may conceivably arise from confusion with his brother Domenico, active into the 1360s, though that explanation is itself conjecture. And in one sentence the label calls the artist “Agostino,” a slip of the patronymic that unintentionally performs the very confusion of father and son that the attribution debate conducts in earnest. That a museum label can drift between the two names, and that the finest scholars can assign the same relief to either man, measures how completely the workshop of Agostino di Giovanni absorbed the identities of those who worked within it.

None of this diminishes the object; it is, rather, the condition of its fascination. Whoever carved it — the son perfecting his painterly manner in the 1340s, or the father proving more versatile than his older reputation allowed — the Cleveland relief remains one of the most refined pieces of Sienese marble carving of its generation: a painted altarpiece rethought as pierced stone, a throne guarded by lions the size of lapdogs, drapery cut to the softness Bartalini could only describe as butter. Until new documents surface from the Sienese archives, the honest caption must carry the attribution as an open question, and the honest viewer may enjoy what the dispute cannot touch: the work itself. The relief closes the triad begun with the signed San Bernardino Madonna and the documented Tarlati chapel — the third and most beautiful of the three, and the only one whose author remains, in the strict sense, unknown.

Style: The “Pictorial” Relief and the Dialogue with Painting

In the modern critical tradition, Giovanni’s importance rests less on the number of his secure works — which is, as we have seen, painfully small — than on a particular way of conceiving relief that the attributed corpus is held to embody. Bartalini’s essay of 1986, whose title speaks of the “novità del rilievo ‘pittorico’” of Giovanni, the novelty of his “pictorial” relief, states the view most fully, and the Enciclopedia dell’Arte Medievale entry summarizes it. In the reliefs of Tino di Camaino or Goro di Gregorio, the argument runs, figures stand out from a flat background as discrete plastic volumes.

In Giovanni’s Stories of John the Baptist on the Arezzo font, and in the somewhat later Volterra reliefs, something different happens: “l’aggetto dal piano di fondo è graduato a seconda della diversa collocazione delle figure nello spazio, per creare un’illusione di ampia profondità” — the projection from the background plane is graduated according to the differing placement of the figures in space, to create an illusion of ample depth. In practice, the physical depth of the carving follows imagined depth in space: nearer figures project more, farther figures less, so that the marble slab ceases to be a neutral ground on which volumes are lined up and becomes instead a field of space. An online summary of the literature on Agostino states the contrast with the father concisely: the son would develop “un rilievo ‘pittorico’ basato sulla graduazione atmosferica degli aggetti,” a pictorial relief based on the atmospheric graduation of projections, while Agostino “continuerà a concepire lo spazio come un allineamento di volumi plastici su un fondo piatto e astratto,” would continue to conceive space as an alignment of plastic volumes on a flat and abstract ground.

This formal argument is bound up with a larger claim about the relation of Sienese sculpture to Sienese painting. The image of Giovanni as the sculptural alter ego of Simone Martini presupposes, as the Enciclopedia dell’Arte Medievale puts it, that in the 1330s and 1340s painting, “e Simone Martini in particolare,” exercised “un generale potere di orientamento,” a general orienting power, over the other arts. The Opera del Duomo, describing the Vallepiatta group, calls it “perfectly in keeping with the style of the Sienese painters of the 14th century,” and scholarship on the Tarlati tomb has long read the Arezzo reliefs against a triple horizon of painted reference: the visual language shared by Tino di Camaino and Simone Martini, the expansive storytelling of Duccio’s Maestà, and Ambrogio Lorenzetti’s capacity to evoke wide landscapes and fortified hill towns. It must be underlined, however, that all of this is comparison of visual culture, not documented biography. No source consulted for this essay records any personal contact between Giovanni and Simone Martini, Ambrogio Lorenzetti or Pietro Lorenzetti. The “alter ego of Simone” is a powerful critical interpretation, and it should be read as such — not converted, as it sometimes is in derivative literature, into a fact about the artist’s life.

The image, moreover, has its own history, and it has not always been flattering. An encyclopedia entry of 1929 could still describe Giovanni as “educato alle forme paterne che sempre ripeté con fredda convenzione” — educated in his father’s forms, which he always repeated with cold convention — a mediocrity known chiefly for the San Bernardino relief. Kreytenberg’s measured account of the Tarlati chapel figures, with their bulky, softly modelled but flattened forms and their weaknesses of proportion, occupies a middle ground between that early dismissal and the later celebration of the pictorial virtuoso. The point deserves emphasis because the disagreement is not merely one of taste: it depends structurally on which works are admitted to the corpus. If the Volterra Stories of Saint Victor and the Cleveland relief are Giovanni’s, then the image of the painterly virtuoso follows almost of itself. If they are Agostino’s, then Giovanni’s securely attested style is narrower and heavier, and the father emerges as a far more versatile artist than the older literature ever allowed. The stylistic portrait of Giovanni di Agostino, in other words, is not a premise of the attribution debate but its product.

Something similar holds for Giovanni’s relation to the legacy of Giovanni Pisano and Tino di Camaino, which is a matter of artistic lineage rather than personal contact. Vasari’s claim that Agostino trained under Giovanni Pisano is, as we have seen, chronologically impossible in the form he gives it. Modern literature suggests instead that Agostino perhaps studied in the workshop of Camaino di Crescentino, the father of Tino di Camaino, and describes his sculptural language as deriving “direttamente da quella di Tino di Camaino per la massività dei volumi sommariamente squadrati” — directly from that of Tino di Camaino in the massiveness of its summarily squared volumes. Giovanni thus inherited the post-Pisano Sienese tradition at one remove, through his father; and the novelty attributed to him consists precisely in the loosening of that inheritance of block-like volume in favour of a graduated, luminous, atmospheric relief.

The Duomo Nuovo and Giovanni’s Architectural Role

The final phase of Giovanni’s career cannot be separated from the greatest architectural gamble of medieval Siena, the extension of the cathedral known as the Duomo Nuovo. The Opera’s historical account supplies the chronology of the enterprise. On 23 August 1339 the Grand General Council of the Bell approved the extension by 212 votes to 132 — approving, in reality, a project already long under way, for according to the chronicler Andrea Dei the foundation stone of the new façade had been laid on 2 February 1330, blessed by the bishops of Siena and Massa; work on extending the church eastwards towards Vallepiatta and on the Baptistery façade had begun as early as 1 May 1317; and from 1331 a campaign had been buying up the buildings on the site. The plan was breathtaking in its ambition: the existing cathedral was to become merely the transept of an immense new church whose nave and aisles would occupy what is now Piazza Jacopo della Quercia. Two ground plans of the project survive in the Opera’s archive.

Giovanni’s appointment as capomaestro on 23 March 1340 came, as the literature observes, “proprio all’indomani della deliberazione,” in the immediate aftermath of the Council’s deliberation of 1339, and it placed him at the head of this enterprise for the rest of his documented life. What exactly the office entailed is less clear than one might wish. Bartalini’s entry in the Enciclopedia dell’Arte Medievale states that the works continued until 1348 “e forse interamente sotto la direzione di G.” — and perhaps entirely under Giovanni’s direction — the “forse” once again marking an inference rather than a certainty; the documentation, the same entry concedes, “non precisa quale fosse il ruolo del capomaestro nei lavori di ricostruzione,” does not specify what the capomaestro’s role in the rebuilding was, though his duties evidently included “la definizione delle soluzioni architettoniche da adottare per realizzare la planimetria,” the definition of the architectural solutions to be adopted in realizing the ground plan.

A review of Bartalini’s monograph of 2019 adds an institutional observation of some importance: it was precisely in the Duomo Nuovo workshop that the capomaestro became a stable office with a high and “piuttosto unico,” rather unique, salary, whereas before then, “al di là dei casi piuttosto eccezionali di Giovanni Pisano e di Tino di Camaino,” beyond the rather exceptional cases of Giovanni Pisano and Tino di Camaino, no such fixed post had existed in the fabric’s organization. Kreytenberg draws from the scale of the undertaking a consequential inference of his own: given the administrative and supervisory burden of that gigantic workshop, Giovanni “non era destinato certo ad assumere incarichi come scultore” — was certainly not destined to take on commissions as a sculptor. The head of the works, on this view, had little time left for the chisel.

The arguments for Giovanni’s authorship of the Duomo Nuovo’s architectural design rest on comparison rather than on any explicit document. An earlier study demonstrated that the proportions of the Duomo Nuovo façade match those of the Tarlati tomb in Arezzo; the underside of the façade’s central window, divided into lozenges, repeats a solution found on the same Arezzo monument; and the portal towards Vallepiatta is structurally close to the Tarlati chapel of 1334, differing chiefly in its greater height. A review of a 1997 study of Trecento architectural drawings discusses one of the two surviving cathedral plans — among the first European drawings executed with a scale — and finds that it matches the parts of the building actually begun so closely as to suggest Giovanni’s name for its authorship. These are reasoned attributions, and the last in particular, the assignment of the drawn plan to Giovanni’s hand, should be treated explicitly as a hypothesis.

To the same moment belongs the contract of 4 February 1340 for the street façade of Palazzo Sansedoni, whose accompanying pen drawing of the façade is celebrated as one of the oldest technical drawings preserved in Europe. Here the sources are not even consistent about the cast of characters: the Dizionario Biografico entry on Agostino names as contractors Agostino, Agostino di Rosso and Cecco di Casino, while the Enciclopedia dell’Arte Medievale includes Giovanni among them, and one scholar has preferred to attribute the drawing itself to Giovanni’s hand. The contract is documented; Giovanni’s participation is reported inconsistently; his authorship of the drawing is a hypothesis; and the façade itself was in any case later completely transformed.

The sculpture of the Duomo Nuovo raises the father-and-son problem in its most acute form, because here the two principal modern readings collide head-on over the very same stones. The Opera’s account names the reliefs in the lunettes above the doors opening onto the loggia of the unfinished façade — a Madonna and Child, and a Redeemer blessing between two cherubs — as displaying “the ‘painterly’ style of Giovanni d’Agostino,” and, quoting a mid-twentieth-century Sienese scholar, hails the Vallepiatta portal as “the finest portal in the whole of Sienese art.” The original statues of that portal’s marble group, the Redeemer adored by two angels, are now displayed in the Museo dell’Opera, casts having replaced them in situ; a publication of 1987 was devoted to their restoration and casting.

Bartalini’s reconstruction assigns to Giovanni, as the principal figurative works of the campaign, the façade lunettes with the blessing Christ and the Madonna and Child, and on the Vallepiatta portal the Christ adored by two angels, the patron saints of Siena and the Annunciation; to the same team he gives the panels in the splayed sides of the façade window, the nave capitals and the vegetal ornament of the portal; and he further places under Giovanni’s direction the middle zone of the unfinished façade above the Baptistery, with the Redeemer, Saint Apollonia and another saint in the gables of its three windows — a zone which, together with the outer walls of the present choir, belongs in fact to the enlargement, having been built when it was still intended as the end of the right transept of the Duomo Nuovo. The review of the 2019 monograph adds that sculpture bound to the architecture, Bauskulptur, absorbed the workshop’s main effort for a long period before monumental figures such as the Vallepiatta group were even begun.

Kreytenberg’s alternative reading is at its most radical precisely here. To Giovanni he gives the monumental Christ group of the Vallepiatta lunette, which he calls “l’opera più importante di G. negli anni 1340-45,” the most important work of Giovanni in the years 1340–45, together with a seated prophet on a capital of the right aisle, and, by comparison with these, a half-figure of a prophet in the south transept of the old Duomo of about 1340 and a Christ enthroned in the parish church of San Lorenzo at Serre di Rapolano. Many of the other sculptures of the Duomo and Duomo Nuovo, however, “non sono affatto in consonanza con il gruppo del Cristo,” are not at all in consonance with the Christ group, and belong in his view to Agostino: the three city patrons and the two angels of the Vallepiatta portal, the façade lunette reliefs with the half-figures of the Madonna and of Christ, a beardless seated prophet on a capital, and the half-figures in the gables of the Baptistery façade windows and on the south side of the choir. His reasoning is in part documentary: since in the contract of 23 March 1340 Agostino had promised advice and collaboration, one could well foresee that the father would receive many of the sculptural commissions while his son bore the capomaestro’s administrative load. The result is a direct and unresolved conflict: the Opera attributes the façade lunettes to Giovanni’s painterly style, and Kreytenberg attributes the very same lunettes to Agostino.

Kreytenberg’s catalogue extends the later corpus beyond the cathedral. He connects to the Vallepiatta Christ a Saint John the Evangelist from a sarcophagus relief, originally part of a Pietà, now in the Museo Nazionale del Palazzo di Venezia in Rome, which he dates to the early 1340s; a statue of Christ enthroned in the Salini collection in Siena, which he places around 1345; and the tomb of Bishop Ranieri Ubertini in San Francesco at Cortona, with its unusual enthroned figure of the bishop. Ubertini died in 1348, yet his figure is close to the Serre di Rapolano Christ, and Kreytenberg accordingly asks whether the commission might have been given shortly before 1340, while the bishop was still alive — a question he poses, it should be noted, without answering it.

One final corrective belongs in this section. The notion, often repeated, that Giovanni designed Siena’s city gates or fountains cannot be sustained on the documents consulted. The Porta Romana is attributed by Vasari to “Agostino et Agnolo,” and modern literature considers an attribution to the father “forse,” perhaps, plausible; Giovanni’s documented contribution to the Fonte del Campo consists of a payment of 3 December 1339 for work on the aqueduct, which is not the same thing as the design of a fountain.

The End of the Career and the Black Death

The documented record of Giovanni ends, as we have seen, on 27 June 1347, and his death in the plague of 1348, though an entirely reasonable inference — the pestilence devastated Siena that year, and the Duomo Nuovo workshop slowed drastically — remains a probability rather than a documented fact.

The fate of the Duomo Nuovo itself has likewise been simplified in the popular telling. The Opera’s history attributes the slowdown after 1348 to two distinct causes, the economic recession triggered by the Black Death and the discovery of stability problems in parts of the building already erected; in 1357 the governing Twelve ordered the demolition of the parts declared unsound. The review of Bartalini’s 2019 monograph presses the revision further, its headline summarizing the argument that the great idea “fu abbandonata dopo il 1348, anno della Morte nera: ma non fu la peste, la causa” — was abandoned after 1348, the year of the Black Death: but the plague was not the cause. The more careful conclusion available from the sources is that the plague coincided with structural and financial difficulties already inherent in the project, aggravated them, and helped to doom it, without being its sole cause. After the definitive abandonment, work to complete the old cathedral resumed under Domenico di Agostino, Giovanni’s brother — a continuity that shows how completely the house of Agostino dominated the Sienese cathedral workshop across the central decades of the fourteenth century, from the father’s generation through both sons.

Critical Fortune: From Vasari’s Silence to the Modern Debate

Giovanni’s critical fortune can be described in four broad phases. The first is the long Vasarian silence, during which the family’s entire output was absorbed into the composite figure of “Agostino et Agnolo.” The Dizionario Biografico entry on Agostino notes that the father enjoyed a “grandissima fama,” a very great fame, down to the middle of the nineteenth century, built largely on Vasari and his early followers — and adds, with some severity, that the few secure works show him to be “di gran lunga inferiore,” by far inferior, to that reputation. Within this inflated paternal fame there was, of course, no room for a son whom Vasari had never named.

The second phase is that of antiquarian and documentary recovery. A sequence of publications gradually retrieved the archival notices on which the present essay rests: eighteenth-century histories of Orvieto Cathedral and collections of letters on Sienese art, an early-nineteenth-century biographical compilation of Sienese artists, and above all the great Sienese document collections of 1854 and 1898, which brought to light the marriage of 1310, the Arezzo chapel contracts, the capomaestro appointments, the payments from Santa Maria della Scala, and the “olim” of 1347. For the first time it became possible to see Giovanni as a person distinct from his father, even if he remained, for the moment, a name without works.

The third phase gave that name an artistic personality. In the early twentieth century, broad surveys of Italian art attributed a handful of statues and figures to Giovanni, and an American art historian of the 1920s published observations on Sienese and Pisan Trecento sculpture that touched on the family. The first coherent catalogue, however, came with Cohn-Goerke’s articles in the Rivista d’arte of 1938–39 and in The Burlington Magazine of 1939, which attributed the Arezzo font reliefs to Giovanni and attempted the first separation of hands within the Tarlati tomb. Mid-century Sienese studies — on the cathedral’s sculpture in 1941, and on unpublished works by Giovanni in 1948 — extended the corpus to the Duomo Nuovo; a major Pisan collection of essays of 1969 identified the Ghini fragments and demonstrated the proportional link between the Tarlati tomb and the Duomo Nuovo façade; and the 1982 exhibition of Gothic art in Siena catalogued the San Bernardino relief and the Vallepiatta group, consolidating the corpus in its now familiar form.

The fourth phase, from the mid-1980s to the present, is one of reconstruction and counter-reconstruction. On one side stands Bartalini’s sustained work: the essay on sculpted space of 1986, the study of the Baptistery façade of 1989, the article on a “possible Domenico d’Agostino” of 1991, the “five postscripts” of 1994, the encyclopedic synthesis of 1995, the chapter in the 2011 survey of Sienese Gothic sculpture from 1260 to 1350, and the monograph of 2019 on the Duomo Nuovo. On the other stands Kreytenberg’s counter-reconstruction: the articles on the Volterra tombs of 1990, on unknown sculptures of Giovanni and Agostino of 1991, on Agostino and Saint Galganus of 1993, on the Ubertini tomb of 1999, and the Dizionario Biografico entry of 2001. Around them, other contributions have kept the questions open — an article of 1985 asked in its very title whether Giovanni was an “artista consapevole,” a self-aware artist, and the 2019 study of the Ghini chapel has reopened the problem of his beginnings. The result of a century of scholarship is a corpus with a secure core and a wide disputed edge, and a central question that remains genuinely unresolved: of everything the workshop produced between 1330 and 1348, how much belongs to the son, and how much to the father?

Conclusion

What, in the end, can be said of Giovanni di Agostino with confidence? The documents establish that he was the son of Agostino di Giovanni and Lagina di Nese, born at some point after their marriage of September 1310; that he worked with his father in Arezzo from 1331 on the chapels of the priest Goro and of the Ghini family in the Pieve, and under his own contract of 28 January 1334 on the Tarlati chapel in the Cathedral; that he was capomaestro of the Opera del Duomo of Siena in 1336–37 and again from 23 March 1340, directing the Duomo Nuovo into the mid-1340s; that he travelled to Orvieto and arranged Carrara marble for its Opera in 1337; that he worked on the aqueduct of the Fonte del Campo and carved lost tombs for the Hospital of Santa Maria della Scala; and that he is last recorded alive on 27 June 1347. The signature establishes one thing more: that he carved the small Madonna and Child with two angels in San Bernardino, and that he wished the stone itself to say so — “Ioh(anne)s magist(r)i Agostini de Se(n)is me fecit.”

Beyond these certainties extends the territory of broadly accepted attribution: the Annunciation and gable relief of the Tarlati chapel, the reliefs of the Arezzo Pieve font, the Ghini chapel fragments in Paris, London and Budapest, the Christ group of the Vallepiatta portal, and a directing role in the architecture and sculptural decoration of the Duomo Nuovo. Beyond that again lies the territory of open debate, where the finest works associated with his name oscillate between him and his father: his share in the Tarlati tomb reliefs, the Volterra Stories of Saint Victor, the Cleveland relief, the façade lunettes of the Duomo Nuovo, the Grosseto portal, the Pistoia and Montepulciano works, the Ubertini tomb at Cortona, and the attribution to his hand of a surviving cathedral plan and of the Sansedoni drawing. And beyond even that lies the rubbish heap of claims that the evidence obliges us to discard: that Giovanni sculpted the Tarlati tomb of 1330, which is signed by his father and Agnolo di Ventura; that he was capomaestro at Orvieto; that he lived until about 1370; that the signed San Bernardino relief is by Agostino; that he made a signed lunette at San Francesco in Arezzo, or a documented Madonna del Latte; and that his death in 1348 is anything more than a well-founded probability.

The shape of the career that emerges from these three territories is itself worth stating plainly, because it is not the shape the popular literature gives it. Giovanni does not appear in the documents as an independent master who later rose to office, but as a son who moved, step by step, from inside his father’s contracts to the head of his city’s greatest enterprise. In 1331 he is paid alongside Agostino by the priest Goro; in 1332 the Ghini make his participation a condition of their contract, and he acts as his father’s procurator; in 1334 Roberto Tarlati contracts with him directly; by November 1336 he is capomaestro of the Opera del Duomo; and on 23 March 1340 he receives that office again for five years, with his father’s consent and his father’s promise of counsel written into the deed. Each stage enlarges his standing without ever detaching him from the house of Agostino. The documented Giovanni is thus less a solitary talent than the most conspicuous product of a family enterprise, and the one secure act of self-assertion in his whole record, the signature in San Bernardino, names him through that family: not “Giovanni” alone, but “Giovanni, son of master Agostino.”

That trajectory also explains why the categories of sculptor and architect cannot be separated in his case. The unit of design that recurs across his documented work is the aedicule: the canopied altar of the priest Goro, the Ghini chapel with its pinnacles and gable, the Tarlati chapel of 1334, and — if the comparisons advanced in the literature hold — the Vallepiatta portal of the Duomo Nuovo, structurally the Arezzo chapel grown taller, set in a façade whose proportions repeat those of the Tarlati tomb. Even the Cleveland relief, whoever carved it, compresses the same canopied architecture into a slab of marble barely seventy centimetres high. What unites the small and the colossal is a consistent habit of thinking in framed, gabled, sheltering structures that hold figures, and it is this habit, more than any single figure style, that the career seems to carry from Arezzo to Siena. If Kreytenberg is right that the capomaestro had little time left for the chisel after 1340, then the drawn plan, the proportional system and the direction of a team of carvers were Giovanni’s mature medium, and the search for his personal hand in individual marbles of the 1340s may be looking, at least in part, in the wrong place.

The material condition of the corpus compounds these difficulties. Almost nothing associated with Giovanni stands where it was made. The Ghini chapel survives as three fragments divided between Paris, London and Budapest; the Volterra shrines have been dismembered into narrative panels, curtain-angels, an effigy and a crowning Madonna, gathered into a diocesan museum that has itself changed premises; the originals of the Vallepiatta portal have been replaced by casts and taken into the Museo dell’Opera; the Sant’Eugenio tabernacle has passed into the Chigi Saracini collection; the Cleveland relief reached America without a recorded provenance from any building; and a mitred head entered the Pinacoteca only in 2021. Each move has cost context, and each new home has added a label, some of which — the Volterra series attributed wholesale to “Agostino di Giovanni and Agnolo di Ventura,” the Cleveland dates of 1310 to 1370, the San Bernardino relief credited to the father — reproduce precisely the confusions this essay has tried to retire. Reconstructing Giovanni has therefore always meant two tasks at once: reassembling scattered stones into plausible monuments, and correcting, one caption at a time, the institutional memory that has grown up around them.

Whatever the final division of hands, the artistic achievement at stake is not in doubt, and it deserves to be stated independently of the name attached to it. Somewhere in the house of Agostino, in the 1330s and 1340s, Sienese relief sculpture learned to graduate its projection according to imagined depth — to treat the slab, in the terms of Bartalini’s analysis, not as a flat ground on which volumes are aligned but as a field of space, in which nearer figures swell and farther ones recede. The Arezzo font, the Volterra Stories, the Cleveland relief and the lunettes of the Duomo Nuovo are the principal witnesses to that change. The attribution debate does not decide whether it happened; it decides only who deserves the credit. On Bartalini’s reading the innovation is the son’s, and the father remains the heir of Tino’s squared volumes; on Kreytenberg’s, a substantial share of the most advanced carving returns to Agostino, who thereby becomes a far more inventive master than his older reputation allowed. Either way, the workshop that Vasari dissolved into a legendary pair of brothers was one of the places where Sienese sculpture came closest to the spatial ambitions of Sienese painting — a claim that rests on the objects themselves, not on any documented acquaintance with Simone Martini or the Lorenzetti.

The terms in which the question might one day be settled can at least be named. The first, and the most decisive, is documentary: a contract, a payment or an inventory attaching a single disputed work to a single name would do more than a further generation of stylistic comparison. The second is material. Some of the basic facts on which argument should rest are not available in the literature consulted for this essay — the dimensions of the signed San Bernardino relief among them — and systematic technical study of the disputed marbles, of their tool marks, drill work, polychromy and gilding, measured against the two fixed points of signature and contract, could narrow a debate that connoisseurship alone has left open. The third is comparative: the acquisition of the Head of a Bishop in 2021 and the renewed study of the Ghini fragments in 2019 show that the corpus is not closed, and that each newly considered piece shifts the balance between father and son. None of these routes guarantees a resolution; all of them would at least move the debate from eloquence toward evidence.

It is fitting, finally, that the largest work of Giovanni’s life should be one he never finished and that no one can securely divide among its makers. The Duomo Nuovo was to reduce the old cathedral to the transept of a church on a scale Siena had never attempted; it was approved in 1339, entrusted to Giovanni in 1340, slowed in 1348, and in 1357 its unsound parts were ordered demolished. What remains — the unfinished façade, its lunettes, the Vallepiatta portal and its Christ adored by angels — is at once the most visible monument of his career and the most contested zone of his catalogue. The enterprise mirrors the man with uncomfortable precision: an ambition documented at its outset, interrupted by catastrophe, carried on afterwards by his brother Domenico within the same family workshop, and left to later centuries as a set of fragments whose authors must be argued rather than read. To stand beneath its unfinished walls is to stand inside the historiographical problem this essay has described.

The historiographical lesson of this case reaches beyond one sculptor. Vasari’s fusion of “Agostino et Agnolo” did not end when the documents refuted it in the nineteenth century; it survives in a subtler and more tenacious form, in the continuing difficulty of drawing the line between father and son within a single, close-knit workshop, where the same contracts, the same scaffolding and perhaps the same blocks of marble passed between two pairs of hands. Bartalini and Kreytenberg have confronted that difficulty with utter seriousness and have reached, on crucial points, opposite conclusions — a disagreement that is not a scandal of the discipline but a faithful register of what the evidence does and does not permit. Whether Giovanni di Agostino was the painterly virtuoso whose marble became “quasi del burro,” almost butter, under the chisel, or a heavier and more conventional master overshadowed by a more versatile father, is a question that style alone cannot close. Until new documents emerge from the Sienese or Aretine archives, the honest portrait of Giovanni remains what this essay has tried to draw: a young man of documented talent, trusted at twenty with a patron’s chapel and at thirty with a cathedral, author of one signed Madonna, probable victim of the great mortality of 1348 — and, at the centre of his small certain oeuvre, a single Latin sentence in which he claimed, against the long silence to come, that the work was his.
