Maestro del Registrum Gregorii
( 25% )
An Artist Without a Name
Among the anonymous painters of the early Middle Ages, few have been praised as highly, or reconstructed as patiently, as the illuminator whom art history calls the Master of the Registrum Gregorii. German scholarship knows him as the Gregormeister, French as the Maître du Registrum Gregorii, Italian as the Maestro del Registrum Gregorii. No medieval document names him, no signature survives, and no chronicle records his training or his death. He exists because a small number of painted leaves made in Trier in the last decades of the tenth century share a quality that sets them apart from everything around them. They treat pictorial space with a calm, a depth and a sense of bodily presence unmatched in their time. His convenience name comes from a single leaf now in the Stadtbibliothek of Trier (Hs. 171/1626a), showing Pope Gregory the Great1 at his writing desk, and from the codex to which that leaf once belonged. Around this image successive generations of scholars have gathered an oeuvre, a chronology and a career. The figure who results is one of the most admired artists of the Ottonian world, and also one of the most hypothetical.
His world was the court of Egbert, archbishop of Trier from 977 to 993. Egbert was the son of Count Dietrich of Holland2, had served at the imperial chancery, and accompanied Otto II3 on his Italian campaigns of 980 and 983. In Trier he became one of the great patrons of his age. His workshops produced goldsmiths’ work, enamels and luxury manuscripts, and his enamel workshop is the only Ottonian one that can be securely located. Trier had once been an imperial residence of the late Roman Empire, its landscape still marked by monumental ruins and its monasteries rich in Carolingian books. It was an unusually fertile setting for an art that looked back to antiquity, and the Gregory Master was its most accomplished exponent.
The Registrum Gregorii and Its Dispersal
The manuscript that gave the Master his name was a copy of the letters of Pope Gregory I, the Registrum epistolarum, commissioned by Egbert and given to his cathedral of Saint Peter. It was originally a substantial volume, reconstructed by nineteenth-century editors of the Register at roughly two hundred and fifty leaves. Only fragments survive, scattered between Trier and Chantilly.
Gregory the Great Inspired by the Dove: The Trier Leaf of the Registrum Gregorii
Trier keeps the leaf with Gregory the Great, a double leaf bearing the title and the dedicatory poem, and a text fragment of thirty-eight leaves. The second great miniature, the enthroned emperor receiving the homage of the provinces, is in the Musée Condé at Chantilly (Ms. 14 bis). It was bought on the London art market in 1862 and is now mounted on card, so its reverse cannot be examined. When and why the codex was broken up is unknown. A Trier cathedral treasury inventory of 1479 still describes a costly silver-covered book of Gregory’s letters. The surviving text leaves entered the city library in 1814, and the Gregory leaf came there in 1827 from the collection of the Trier book collector Johann Peter Job Hermes.
The dedicatory poem, written in gold letters on a purple ground, is the essential primary document for dating the book. Its hexameters relate that Egbert, bishop of the Trevirans, ordered the volume made in honour of Saint Peter, covered in gold and adorned with gems, in the serene times of Caesar Otto, who held the Roman sceptre and ruled Italy and the Franks, and whose compater the archbishop had been. The poet then borrows Virgil’s description of the Golden Age under Saturn (Aeneid 8.324–327) and applies it to Otto’s reign, before recalling that the emperor died in Rome and was buried in the atrium of Saint Peter’s.
Otto II died in Rome in December 983 and was buried at Saint Peter’s, so the book cannot have been completed before that date. It must also predate Egbert’s death in 993. The dates “around 983” or “around 985” commonly given in catalogues are reasonable estimates within that decade, not documented years. Hartmut Hoffmann recognised the Master’s own hand in the rustic capitals of these display pages, which suggests that the painter was also a skilled scribe. The text fragment itself was written by other hands, and its modest initials are not his.
The Trier leaf, trimmed at its edges to about 26.5 by 19.5 centimetres, illustrates a legend about how Gregory’s writings came into being. The pope, identified by the inscription GREGORIUS PP, sits enthroned at a lectern within an architecture of columns and roofs, while the dove of the Holy Spirit perches on his shoulder and speaks into his ear. Behind a curtain sits his secretary, labelled Notarius, holding a wax tablet. According to the legend, the notary grew puzzled during a long pause in the dictation, pierced the curtain with his stylus and peered through, discovering the divine source of his master’s words. The painter fixes exactly this moment. A theological claim, that Gregory wrote under the direct guidance of the Spirit as the evangelists had, becomes an intimate scene of concealment and revelation.
The leaf’s lasting fame rests less on its subject than on its handling of space. The pope’s large, softly modelled body sits within successive planes of curtain, column and roof. The curtain does not simply hang as a flat backdrop but bends around the two columns at Gregory’s right, so that the eye moves through the image layer by layer. The 1993 Trier exhibition catalogue spoke of these intricately overlapping layers of space and concluded that the Master understood depth and plasticity better than any known artist of his time. The palette is light and tender and the composition balanced, so the image gains its grandeur through quiet monumentality rather than hieratic rigidity.
Technical study has shown that the painter’s underdrawing, combining silverpoint with coloured pen and already worked up with washes, was revised in the course of painting: the curtain was first planned on Gregory’s other side. The revision shows an artist thinking spatially while he worked, testing alternatives rather than following a fixed model.
One detail repays careful attention. The words on the notary’s tablet are not taken from Gregory but from Ecclesiasticus 14:22: Beatus vir qui in sapientia sua morabitur, “blessed is the man who abides in wisdom.” Within the leaf alone the quotation seems a general praise of learning. Its full meaning appears only when the Gregory leaf is set beside the image that once faced it.
Otto Enthroned: Imperial Majesty and the Provinces
The Chantilly leaf shows a ruler enthroned beneath a canopy, identified by the inscription
Otto imperator augustus.
Four crowned female figures approach him in homage, two on each side, labelled Germania, Francia, Italia and Alamannia. They stand staggered in depth, and the receding architecture of the throne and canopy creates a convincing space. That space is nevertheless subordinated to a hierarchy of scale which makes the emperor appear larger and more present than everything around him. The painter thus reconciles two principles that might seem opposed, illusionistic depth inherited from antiquity and the medieval logic of hierarchical size, and from that reconciliation comes the image’s peculiar authority.
The motif of personified provinces bringing tribute has Late Antique antecedents, among them the imagery of the Roman Calendar of 354, which was probably accessible to Carolingian and Ottonian artists in the original or in a copy. The choice of provinces is politically eloquent. By naming Alamannia, that is Swabia, alongside Germania, Francia and Italia, the image presents the empire as a composite of peoples and kingdoms held together in the person of the emperor. Together with the Virgilian echoes of the dedicatory poem, it places Ottonian rule within the tradition of Roman imperial majesty.
Which Otto is portrayed has been debated. The Château de Chantilly identifies the leaf as a portrait of Otto II, and several arguments support this. The leaf’s proportions are compatible with the rest of the Registrum, the dedicatory poem laments Otto II by name, and the book was evidently conceived as a memorial to him. Others have seen the young Otto III, but he was crowned emperor only in 996, three years after Egbert’s death. An imperial portrait is in any case an unusual element in a collection of papal letters, and it has been suggested that Egbert added it late in the production as an act of homage to the dead emperor.
The most illuminating interpretation of the two miniatures is Carl Nordenfalk’s argument, set out in his 1985 study of the Registrum, that the Gregory and Otto leaves originally faced each other across an opening of the book. Nordenfalk identified a precise model for this arrangement in a Byzantine Bible, the Niketas Bible now in Copenhagen. There King Solomon sits enthroned in conversation with Jesus Sirach, the author of Ecclesiasticus, seated before him. The Gregory Master adopted this composition, putting Gregory in place of Sirach and the Ottonian emperor in place of Solomon.
Seen this way, the quotation on the notary’s tablet is no longer a generic sentiment. It is a verse from Sirach’s own book, now spoken across the opening to a ruler who occupies Solomon’s place. The identification of Ottonian kings with Solomon was current at the time: Hrotsvit of Gandersheim had already celebrated an Ottonian ruler as a Solomon reborn. The blessed man who abides in wisdom is at once the inspired pope and the wise emperor, and the homage of the provinces on the facing page completes a vision in which divine wisdom, transmitted through the papacy, sustains imperial rule.
The diptych was also a statement about its patron. Egbert presided over a see that claimed to be the oldest north of the Alps, and he had served the emperor as chancellor and been bound to him as compater. The opening he commissioned shows the ideal harmony of the two powers between which he himself moved.
Egbert’s Politics and the Codex Egberti
The years in which the Registrum was made were turbulent, and Egbert’s choices in them bear on the Master’s career. After Otto II’s death the archbishop at first supported the claims of Duke Henry the Quarrelsome of Bavaria against the child Otto III, returning to the Ottonian party only in 985. Nordenfalk used this episode to propose that the Master spent a period at Reichenau during the turmoil. The suggestion is attractive, but it remains a hypothesis rather than a documented fact.
The principal monument of Egbert’s patronage is the Codex Egberti (Trier, Stadtbibliothek, Hs. 24), a Gospel lectionary whose fifty-one narrative miniatures form the earliest surviving extensive cycle of the life of Christ in a Western book. Its dedication page shows Egbert enthroned between two small monks, Keraldus and Heribertus, labelled Augienses, monks of Reichenau, presenting him the book. The monks establish a Reichenau connection for the book. The picture does not say whether either was a scribe or a painter, and whether the lectionary was made on the island or in Trier is still debated. Within this collaborative enterprise the photographic catalogue of the Bibliotheca Hertziana and the Bildarchiv Foto Marburg gives the Gregory Master seven narrative miniatures, on fols. 9v, 10v, 12r, 13r, 15v, 22r and 22v: the Annunciation, the Visitation, the Dream of Joseph, the Nativity with the Annunciation to the Shepherds, the Massacre of the Innocents, Christ and the Centurion of Capernaum, and the Healing of Peter’s Mother-in-law. The description issued with the 2005 facsimile assigns him a different share, the portraits of Egbert and the evangelists and the opening Christological miniatures. The seven scenes of the catalogue are the ones counted here.
What distinguishes these seven scenes is not only style but technique, and the technical evidence published in the 1993 Trier commemorative volume is among the most persuasive in the literature. The Master alone among the painters of the codex used azurite, alone worked his underdrawings with washes, and painted his backgrounds first without reserving the drawn figures, so that the figures had to be built up over the background layers. His thick paint has suffered more from the turning of the pages than that of his colleagues. He also applied gold leaf cut to shape and glued on after the painting was complete, a practice found again in the Registrum leaves, the Strahov Gospels and a single leaf with Saint Mark. These habits suggested to the author of the technical study that the Master may not have been trained as a book painter in the conventional sense, and his handling of gold has prompted the suggestion that he came from a goldsmith’s background. The suggestion fits the culture of Egbert’s Trier, where metalwork and painting flourished side by side, but it remains a suggestion.
Gospels, Sacramentaries and Psalters
The grandest manuscript associated with the Master is the Sainte-Chapelle Gospels (Paris, Bibliothèque nationale de France, lat. 8851), a large codex written in gold Caroline minuscule4. The Bibliothèque nationale’s catalogue attributes its decoration to the Master. It comprises a Christ in Majesty surrounded by medallions of the evangelists and their symbols, painted canon tables, and portraits of the four evangelists, left partly unfinished, with frames on several pages still only sketched in lead. Hoffmann compared the inscription in the Luke portrait with the minuscule known to be the Master’s, which supports the attribution on palaeographic as well as stylistic grounds.
Christ in Majesty with the Evangelists: The Frontispiece of the Sainte-Chapelle Gospels
This page opens the Gospel book now known after the Sainte-Chapelle in Paris, one of the most ambitious works associated with the Master of the Registrum Gregorii. The Bibliothèque nationale de France describes a large codex written in gold Caroline minuscule. It attributes to the Master its decoration of this Christ in Majesty, the painted canon tables and the four evangelist portraits, some of which were left unfinished. The book is usually dated around 984. A recent technical study by INHA and the BnF dates it more broadly to 979–989. Its history after Trier is well documented. It was at the abbey of Echternach before 1039, passed later to the French crown, and was given by Charles V to the Sainte-Chapelle in 1379. As the first full-page image of the book, this miniature announces the Gospel text as the word of Christ transmitted through the four evangelists.
The page is built on a rigorous geometric scheme. A pointed oval mandorla occupies the centre and holds the enthroned Christ. Four large green circles fill the corners, each containing an evangelist at work. Four smaller roundels sit on the axes between them, holding the evangelist symbols. These shapes float on a deep purple ground, framed by orange and gold bands, with small gilded leaf ornaments at the outer corners. The arrangement recalls a cross and a cosmic diagram at once: Christ at the centre, the Gospel writers at the four corners of the world, and their symbols at the cardinal points. Its symmetry gives the page the stillness of an icon, while the slight variations among the figures keep it alive.
Christ sits frontally on a block throne with green cushions, his bare feet resting on a footstool. He wears a light blue tunic and a red mantle that sweeps across his lap in broad, softly modelled folds. Behind his head is a halo marked with a cross. He raises his right hand in blessing and holds in his left a closed book with a jewelled cover, the Gospel itself. His face is youthful, calm and direct, and his gaze meets the viewer’s. The mandorla’s gold ground isolates him from the purple field, and its light-coloured borders give the impression of a glowing aura rather than a flat frame. An inscription in Greek characters runs around the inner edge of the mandorla; its text is not transcribed here.
The four evangelists each sit on a block seat with a footstool, bent over their writing at slender lecterns. They wear tunics and mantles in pale blue, red, ochre and purple. Gold halos frame heads turned toward their texts. The two upper figures write on long scrolls that unroll over their lecterns, while the two lower figures write in open codices. The distinction may suggest the passage from scroll to book in the transmission of the Gospel, though the painter may simply have sought variety. Faint inscriptions name the figures, and John’s name is clearly legible at the upper right. Each evangelist is absorbed in his task and none looks toward Christ, so their relation to him is conveyed by the composition rather than by gesture.
In the four small roundels appear the evangelist symbols: an eagle above, a winged lion at the left, a winged ox at the right and an angel below. Gold capitals on the purple ground carry Latin verses that interpret the image. They read
Quatuor haec Dominum signant animalia Christum: est homo nascendo, vitulusque sacer moriendo, et leo surgendo, caelos aquilaque petendo. Nec minus hos scribas animalia et ipsa figurant.
In translation: “These four creatures signify Christ the Lord: he is man in being born, the sacred calf in dying, the lion in rising, and the eagle in seeking the heavens; no less do these creatures also figure these writers.” The verses explain the double meaning of the symbols. They stand for the four evangelists, and they also represent the four mysteries of Christ’s life: the Incarnation, the sacrificial death, the Resurrection and the Ascension. The page thus reads both as an image of the Gospels’ authors and as a compressed account of salvation.
The page is notable for its rich and carefully balanced colour. The deep purple ground imitates the purple parchment of imperial and Late Antique luxury books. It sets off the gold of the mandorla, the halos and the lettering, and the green of the evangelists’ roundels. The green grounds are painted with lighter edges that fade toward the purple, giving each roundel a sense of luminous depth rather than a hard outline. The 2023 INHA and BnF study identified yellow ochre in the mantles of the medallion figures on this page, among other materials. The modelling of drapery is soft and graded, with highlights laid over darker tones, in keeping with the painter’s characteristic manner.
The theme of Christ in Majesty surrounded by the evangelists and their symbols was well established in Carolingian Gospel books, and the Master’s style draws on Carolingian painting from Tours and on Late Antique models. His treatment of the theme is nevertheless distinctive. The figures have a classical calm and bodily weight, and the drapery falls in long, even curves rather than agitated folds. The colouring is luminous rather than heavy. The evangelists of this manuscript look both to classical figure types and to the Ada Gospels of Charlemagne’s5 court school, which was then at Saint Maximin in Trier. The page therefore represents not a copy but a synthesis, in which inherited forms are ordered into a new and harmonious whole.
The frontispiece is among the most balanced and serene images associated with the Master of the Registrum Gregorii, and it shows his art at its most monumental. Whether the work of a single painter or, as recent research has proposed, of a closely collaborating Trier workshop, it embodies the classicising ideal of Egbert’s Trier. Its theological programme, its geometric clarity and its restrained colour combine to present the Gospel book as a sacred object worthy of imperial and ecclesiastical patronage. Its later presence at Echternach, where the manuscript served as a model, shows that the image also shaped the illumination of the following generations.
The Opening of Jerome’s Letter to Damasus: The Initial Page of the Sainte-Chapelle Gospels
This page opens the first text of the Gospel book: Jerome’s6 letter to Pope Damasus7, known from its first words as Novum opus. In it Jerome presented his revision of the Latin Gospels, undertaken at the pope’s request in the 380s. Medieval Gospel books often placed this letter at their head, so that the reader encountered first the account of how the text had been corrected and authorised. The display panel reads
Beatissimo papae Damaso Hieronimus. Novum opus facere me cogis ex veteri:
“To the most blessed Pope Damasus, Jerome. You compel me to make a new work out of an old one.” The page thus introduces the book through the voice of its translator, addressed to the highest authority of the Church.
The page is divided into two unequal columns, and the division expresses a clear hierarchy of importance. The left column is a tall purple panel that holds the monumental initial and the display capitals of the address. The right column carries the continuation of the letter in a single column of gold minuscule written directly on the bare parchment. The eye moves from the overwhelming initial, through the measured capitals, into the steady rhythm of the text. The same gold binds all three levels together, while size, script and ground mark the passage from solemn opening to readable text. The folio number in the upper right corner is a later addition.
The initial B dominates the page. Its upright shaft and two bowls are formed of broad gold bands edged with white interlace, and small square clasps join the bowls to the shaft. Within the letter, gold vine scrolls spiral out from the stems in dense, symmetrical curls ending in small leaves and trefoils. The intervals between the tendrils are filled with blue, green and soft pink grounds, sprinkled with tiny white dots in groups of three. The letter is both architecture and ornament: its outline remains perfectly legible, while its interior teems with controlled vegetal growth. Set against the deep purple of the panel, the gold seems to glow, and the whole letter takes on the character of a precious metalwork object rather than a painted sign.
Around and below the B, gold capitals complete the address. The letters EA and TIS run beside the shaft, and two full lines follow:
SIMO PAPAE DA and MASO HIERONIMUS.
A smaller initial N follows, built on the same principles as the B, with gold bands and scrolling vines on coloured grounds. Beside and below it the capitals continue:
OVUM / OPUS FA / CERE ME / COGIS EX.
The capitals are generously spaced and carefully proportioned, and their adjustment to the shapes of the initials shows that script and ornament were planned together. The repetition of the initial type on two scales creates a rhythm down the panel and links the address to the opening words of the letter.
The text column is written in gold minuscule, as is the whole manuscript, according to the catalogue of the Bibliothèque nationale. Gold script was among the costliest forms of book production in the early Middle Ages and was reserved for books of exceptional status. The letters are regular and well spaced, with clear word separation and occasional abbreviation marks. The column continues Jerome’s argument: the revision is a pious labour but a dangerous presumption, since anyone who finds the familiar text altered will cry out against the reviser as a forger and a sacrilegious man. The page breaks off as Jerome turns to the two consolations he finds against such hostility, the first being that the supreme pontiff himself commanded the work.
The initial belongs to a type of gold vine-scroll initial that flourished in Ottonian book painting at Trier and Reichenau. Its interlace-edged bands, spiralling tendrils and coloured grounds draw on Carolingian traditions. They also show a close relationship with the initials of the Reichenau circle associated with the Gero Codex, to which the Master’s own initials have been compared. The Bibliothèque nationale attributes the manuscript’s decoration to the Master of the Registrum Gregorii. Whether he executed the ornamental initials himself or directed collaborators is not established, and the caption therefore names the Trier workshop as well. The quality of the work is nonetheless consistent with the figure pages of the book.
The palette is limited and deliberate: gold, deep purple, and the blue, green and pink of the grounds within the letters. The purple panel recalls the stained parchment of imperial luxury books, as does the painted purple ground of the Christ in Majesty page, and lends the opening a ceremonial weight. The small white dots in the coloured fields add sparkle and recall the effect of pearls or enamel. In this the page resembles the goldsmiths’ work produced in Egbert’s Trier, and the affinity has been noted for the Master’s painting more generally. The contrast between the dense, coloured panel and the open, pale parchment of the text column gives the page its striking balance.
As the first text page after the Christ in Majesty, this opening forms part of a carefully staged entry into the book. The reader passes from the vision of Christ and the evangelists to the voice of Jerome, who guarantees the integrity of the text. Only then come the canon tables and the Gospels themselves. The splendour of the initial honours not only the letter but the whole tradition of textual authority it represents, from Jerome through Pope Damasus to the Church that received the corrected Gospels. Later, at Echternach, the manuscript served as a model for local illuminators. Pages like this one helped to transmit the gold vine-scroll initial to the next generation of Ottonian book painting.
Saint Matthew Writing: The First Evangelist Portrait of the Sainte-Chapelle Gospels
This miniature opens the Gospel of Matthew, the first of the four evangelist portraits that the Bibliothèque nationale attributes to the Master of the Registrum Gregorii. It follows Jerome’s letter and the canon tables, and it precedes the incipit page of Matthew’s text on fol. 16v. The page is complete, unlike some later pages of the book whose frames remained sketched in lead. It therefore shows clearly how the painter conceived an evangelist portrait: a figure at work within a monumental architecture, crowned by his symbol and by a verse that explains his place among the Gospels.
A semicircular arch springs from two columns and encloses the whole scene. The columns are painted in purple and blue marbling flecked with gold, and stand on gilded bases beneath pink foliate capitals of antique type. The arch is outlined in pink and filled with a band of gold vine scrolls on a dark ground, echoing the ornament of the book’s initials. Behind and above it rises a pink wall articulated by small blind arcades, suggesting a building seen from the front. The frame is not merely a border. It defines a stage, open toward the viewer, in which the evangelist sits as if in an architectural niche.
Within the lunette, against a deep blue ground, appears the angel, symbol of Matthew, seen half-length with outspread pink wings and a gold halo. He wears a white tunic and an ochre mantle and holds an unrolled scroll. The words on it can be read as
Cum esset desponsata mater Ihesu Maria Ioseph, “When Mary the mother of Jesus was betrothed to Joseph” (Matthew 1:18).
The verse introduces the Gospel’s account of Christ’s human birth, which is why Matthew’s symbol is a man. The angel looks outward rather than down at the evangelist, and his position above the scene makes him a figure of heavenly inspiration presiding over the act of writing below.
A purple band beneath the lunette carries two lines of gold capitals. They read
Hoc evangelium quod ponitur ordine primum
and, in a second line partly abraded, state that Matthew wrote it in the Hebrew tongue, ending
scribit sermone Matheus.
The sense is: “This Gospel, which is placed first in order, Matthew writes in the Hebrew language.” The verse records the early tradition that Matthew composed his Gospel in Hebrew, and it explains why his book stands first in the canon. The text thus joins image and learning, giving the portrait a scholarly as well as a devotional function.
Red curtains hang from the beam of the arch and are drawn aside and tied around the columns. Their folds are painted in graded tones, and each carries a decorated band and a hem cut in zigzag points. The motif comes from Late Antique and Carolingian representations of rulers and authors, where drawn curtains reveal a figure of honour. Here they create a further layer of space between the frame and the evangelist and give the scene a sense of solemn disclosure: the viewer is admitted, as it were, into the room where the Gospel is being written.
Matthew sits in three-quarter view on a folding stool whose legs end in animal heads and clawed feet, with a red cushion on its seat. He is shown as an elderly man with grey hair and beard and a large gold halo. He wears a white tunic with gold bands at the shoulder and sleeve and a mauve mantle wrapped around his body and legs in softly modelled folds. A closed book with a gold cover rests on his lap, and his bare feet are placed on a pink footstool. He bends toward a tall lectern on a turned baluster stand, his pen moving across an open book where the first letters of his Gospel, Liber generationis, appear to be written. An inkhorn is fixed to the edge of the desk. His concentration is calm and steady, and the gentle curve of his back and neck conveys the absorption of the writer rather than the ecstasy of inspiration.
The figure is placed on a green ground that rises behind him in paler horizontal bands, suggesting a distant horizon. The painter does not construct a deep interior, but the arrangement of stool, footstool and lectern gives the figure a firm position in space. The palette is luminous: the pink of the architecture and curtains, the blue of the lunette, the green of the ground, and the white and mauve of the evangelist’s garments. The INHA and BnF study of 2023 identified verdigris in the green of the lower background. The drapery is modelled with soft highlights rather than hard lines, and the body beneath it has weight and volume, in keeping with the classical calm characteristic of the Master’s figures.
The type of the seated evangelist writing beneath an arch, with his symbol above, was widespread in Carolingian Gospel books. The evangelists of this manuscript have been related both to classical figure types and to the Ada Gospels of Charlemagne’s court school, which was then kept at Saint Maximin in Trier. The Master reworked these models with exceptional restraint. The architecture is clear, the colour harmonious, and the figure balanced between dignity and naturalness. Whether the page was painted by the Master alone or within a closely collaborating Trier workshop, it stands among the finest evangelist portraits of the Ottonian period. Its later presence at Echternach, where the manuscript served as a model, extended its influence to the next generation of book painters.
Liber generationis: The Incipit of Matthew in the Sainte-Chapelle Gospels
This page opens the Gospel of Matthew with its first words:
Liber generationis Iesu Christi filii David, “The book of the generation of Jesus Christ, the son of David” (Matthew 1:1).
It follows the evangelist portrait on fol. 15v, so that the reader sees Matthew writing and then the opening of his Gospel. The text is reduced to a few monumental letters filling almost the entire page. The opening words become an image in their own right, to be contemplated as well as read. This treatment of the first Gospel incipit as a full-page display was a long-standing tradition in Insular and Carolingian books, and the Trier painters gave it a distinctive classicising form.
The dominant element is a monogram formed by an L and an I interlocked. The L occupies the left side and the bottom of the panel, its upright and its foot built of broad gold bands. The I rises in the middle. The shafts are filled with interlace patterns worked in gold over blue, pale violet and white, and their ends terminate in dense knots of gold interlace sprouting leaf-like finials sprinkled with white dots. The vertical rhythm of the two shafts and the horizontal foot give the panel a firm structure, while the interlace introduces a restless, intricate surface. Ornament and legibility are held in careful balance: the letters remain clear even as they become fields of decoration.
Between and beside the shafts, tall gold capitals spell out the rest of the words. B, E and R stand one above another next to the I, completing LIBER. To the right, GE, NE, RA and TIO form GENERATIO in a staggered column. Beneath the foot of the L, a single line of smaller gold capitals reads NIS IHU XPI FILII DAVID, completing generationis and using the traditional abbreviations for the names of Jesus and Christ. The capitals are classical in proportion, with clear strokes and fine serifs, and their varying sizes are adjusted to the spaces left by the monogram. This careful fitting of letters to the panel shows script and design planned as a single composition.
The letters stand on a deep purple panel painted with faint horizontal bands, imitating the purple parchment of imperial and Late Antique luxury books. The purple is enclosed by a broad green field, and both are framed by the gold border. The contrast of gold against purple, and of purple against green, gives the page a glowing intensity comparable to the Christ in Majesty frontispiece. Some of the original splendour has been lost: the parchment in the left part of the green field is torn and pierced by several holes, perhaps from damage to the pigment layer or the skin itself.
A broad frame surrounds the whole composition, composed of bands of gold vine scrolls on a pale ground. Its outer and inner edges are marked with lines of purple and blue and rows of small white dots. The vine scroll recalls the ornament of the arch on the facing evangelist portrait and of the book’s initials, and it ties the page into the decorative system of the whole manuscript. The frame also serves as a setting for the eight small images placed at its corners and at the midpoints of its sides, so that the incipit is literally surrounded by figures.
In square fields at the four corners appear the symbols of the evangelists, each against a gold ground: the angel for Matthew at the top left, the eagle for John at the top right, the winged lion for Mark at the bottom left and the winged ox for Luke at the bottom right. Small inscriptions, partly legible, label them. Their presence on Matthew’s incipit page indicates that the opening of the first Gospel stands for the whole fourfold Gospel. The symbols here are painted with the same calm modelling and luminous colour as the figure pages, which suggests that they belong to the same campaign of decoration.
At the midpoint of each side of the frame is a circular medallion containing the bust of a young, beardless man wearing a richly jewelled collar, set against a gold ground. Faint inscriptions accompany the busts, but they are only partly legible in this reproduction. Following Carl Nordenfalk, the Bibliothèque nationale’s catalogue reads them as four members of the Ottonian house: Henry I, Otto I, Otto II and Henry the Quarrelsome, the duke of Bavaria who claimed the throne after Otto II’s death in 983. On this reading the manuscript would have been made in 984 and might have been intended for Henry’s bid for kingship, which Archbishop Egbert at first supported. The identification of the busts and the hypothesis of a coronation gift are contested, however, and other readings of the inscriptions have been proposed. Whatever their exact identity, the medallions place the Gospel book within a dynastic and political context unusual for an incipit page.
The page brings together the three dimensions of the manuscript: sacred text, artistic splendour and political meaning. The monumental letters honour the opening of the Gospel, the evangelist symbols frame it within the fourfold Gospel, and the ruler medallions connect it to the Ottonian dynasty and perhaps to the crisis of succession in 984. The Bibliothèque nationale attributes the decoration of the book to the Master of the Registrum Gregorii. The ornamental work may have been shared within a closely collaborating Trier workshop, and the caption reflects that possibility. The page shows how in Egbert’s Trier the art of the book could serve both devotion and the representation of power.
Saint Mark as Bishop: The Evangelist Portrait on Fol. 52v of the Sainte-Chapelle Gospels
This miniature introduces the Gospel of Mark, the second of the four evangelist portraits that the Bibliothèque nationale attributes to the Master of the Registrum Gregorii. It follows the same basic scheme as the portrait of Matthew on fol. 15v: a figure enthroned beneath an arch crowned by his symbol and an inscribed verse. Within this shared framework, however, the painter introduced striking differences in architecture, colour and above all in the presentation of the evangelist himself. A large arch on two columns encloses the scene. The columns are painted in green and blue marbling and decorated with spiralling gold tendrils, beneath pale foliate capitals of antique type. The arch is composed of concentric bands: an outer gold band, a band of white interlace on gold and a green band bordered by rows of white dots. In the spandrels, ochre panels with squared ornament suggest the face of a building. Within this outer frame a second architecture appears: a pink arcade of three round arches carried on slender columns with Corinthian capitals, crowned by a frieze with small roundels. The interiors of the arches are painted in warm ochre, and the evangelist sits in the central bay. The double architecture creates a sense of layered space and gives the figure the setting of a palace or a church apse.
The lunette holds Mark’s symbol, a winged lion with a gold halo, set against a blue ground. The lion lies on the inscribed band, its pink wings spread, its tail curling over its back, and its forepaws resting on a closed book with a gold cover. Its mane is rendered in fine gold strokes, and its head turns in profile with an alert, almost human expression. As in the Matthew page, the symbol does not look down toward the evangelist but outward, standing above the scene as an emblem of the Gospel’s heavenly origin.
A purple band beneath the lion carries two lines of gold capitals. The first appears to describe Mark as the disciple of Peter, ending with atque mathites, a Latin form of the Greek word for disciple. The second names Mark and ends with the word primus. Parts of both lines are hard to read and are not transcribed in full here. The reference to Peter reflects the ancient tradition that Mark wrote his Gospel as Peter’s disciple and interpreter in Rome, a tradition that also explains the ecclesiastical character of his portrait.
The most remarkable feature of the page is the way Mark is dressed. Instead of the tunic and mantle of an antique author, he wears the vestments of a bishop: a blue chasuble over pale tunics and a white pallium marked with black crosses, the insignia of metropolitan rank. This presentation reflects the tradition that Mark founded the church of Alexandria and was its first bishop. The evangelist appears as an elderly, grey-haired man with a gold halo, seated frontally on a throne with animal-head arms and lion-paw feet, a red cushion behind him and his feet on a stepped footstool. He holds a closed book in his left hand and with his right dips a quill into an inkwell placed on a slender turned stand. To the right stands a tall cabinet lectern supporting open books, with a scroll hanging from its front. The figure combines the dignity of a prelate with the activity of a writer.
The portrait shows a close relationship with the Master’s leaf of Gregory the Great in Trier. In both images a haloed churchman in a blue chasuble and white pallium sits frontally on a throne with animal-head arms and lion-paw feet, his feet on a stepped footstool, beside a tall cabinet-like lectern. The similarity of posture, costume and furniture is too close to be accidental. It supports the attribution of the Sainte-Chapelle evangelists to the painter of the Registrum Gregorii, or at least to the same Trier workshop working from shared models. It also suggests a conscious parallel between the evangelist and the great pope, both presented as authoritative bishops and authors of sacred texts.
The palette is warm and luminous, dominated by the ochre ground of the arches, the pink of the arcade and the blue of the chasuble. These are set off by the white of the pallium and accents of gold, green and red. The 2023 INHA and BnF study identified yellow ochre in the painted walls and background of this page. The drapery is modelled with soft highlights, and the figure has a quiet, monumental volume. A faint sketch of a seated figure in the lower margin of the page, perhaps a trial drawing, offers a glimpse of the working process. Some staining is visible along the right edge of the parchment.
The Mark portrait is one of the most original images of the Sainte-Chapelle Gospels. By presenting the evangelist as a bishop, the Master gave visual form to the idea of the Gospel as the foundation of the Church’s teaching authority, transmitted through apostolic succession from Peter to Mark and his see. The composition is clear and balanced, the architecture elaborate yet coherent, and the figure calm and dignified, qualities that characterise the classicising art of Egbert’s Trier. Whether painted by the Master himself or within a closely collaborating workshop, the page shows the Trier painters reinterpreting the traditional evangelist portrait in the light of contemporary ecclesiastical ideals.
Saint Luke Writing: The Evangelist Portrait on Fol. 75v of the Sainte-Chapelle Gospels
This miniature introduces the Gospel of Luke, the third of the four evangelist portraits that the Bibliothèque nationale attributes to the Master of the Registrum Gregorii. It follows the same scheme as the portraits of Matthew and Mark: an arch crowned by the evangelist’s symbol and a verse inscription, enclosing the evangelist at work within an architectural setting. Here too the painter varied the formula. Luke is neither the contemplative elderly scribe of Matthew’s page nor the bishop of Mark’s, but an author caught in the act of composition, turning between two books. The page has a particular importance for the attribution of the whole manuscript, as discussed below.
A large arch on two columns frames the scene. The columns are painted in blue and purple marbling covered with delicate white vine tendrils, beneath pink foliate capitals topped by small blue rosettes. The arch consists of a gold outer band, a band of vine scrolls with green and red rosettes on a pale ground, and rows of white dots. In the spandrels, purple panels with square ornaments suggest the facade of a building. Beneath the arch runs a beam decorated with a meander frieze. The inner space is articulated by slender white columns with Corinthian capitals, between which mauve curtains are drawn aside and looped. The green ground behind the figure gives the interior a cool luminosity that contrasts with the warm tones of the frame.
The lunette holds Luke’s symbol, the winged ox, set against a blue ground framed by a green band. The animal reclines on the inscribed band, its white wings spread behind it, its tail curling upward, and its forelegs resting on a closed book. Its horned head, crowned with a gold halo, turns frontally toward the viewer with an expression of calm alertness. The reddish-brown body is modelled with soft gradations that give it bulk and solidity. Like the angel and the lion on the earlier portraits, the ox does not look toward the evangelist but outward, standing above the scene as an emblem of the Gospel’s heavenly authority.
A purple band beneath the ox carries two lines of gold capitals. The words read as
Hic est spermologi Lucas sacer assecla Pauli, inclita qui Domini meruit magnalia scribere Christi.
“Here is Luke, the holy companion of Paul, the sower of the Word, who was found worthy to write the glorious great deeds of Christ the Lord.”
Luke sits in three-quarter view on a gold block throne with a pale cushion, his bare feet resting on an arcaded footstool. He is an elderly man with white hair and beard and a large gold halo, dressed in a light blue tunic and an orange-red mantle. The mantle is gathered in a broad circular fold over his belly and falls in long curves over his knees. He holds a pen in one hand, raised before his chest, and stretches the other toward an open book on a grey pedestal lectern to the right.
Interestingly, the word spermologi is a Latinised form of the Greek spermologos, literally “seed-picker”. In Acts 17:18 the Athenian philosophers used it mockingly of Paul, calling him a babbler, and the Vulgate renders it seminiverbius. Medieval exegesis turned the insult into praise: Paul as the sower of the seed of the Word. The verse here uses it in that positive sense, as an epithet of Paul.
Behind him to the left, a tall stand supports another book, whose page carries the opening words of his Gospel narrative:
Fuit in / diebus / herod(is) / regis iu/deae sa/cerdos / quidam / nomi/ne za/chari/as
“There was in the days of Herod, the king of Judaea, a certain priest named Zacharias” (Luke 1:5). The evangelist’s turning posture, between the book behind him and the book before him, suggests the act of composition: consulting, reflecting and writing.
The writing within this miniature has a special place in the scholarship. Hartmut Hoffmann compared the inscription in the Luke portrait with the minuscule known to be the Master’s own hand. The comparison supports the attribution of the evangelist portraits to the painter of the Registrum Gregorii on palaeographic as well as stylistic grounds, since the Master was both painter and scribe. The text on the book is not merely decorative. It makes the picture a demonstration of the act it represents, the writing of the Gospel, and it may preserve the hand of the painter himself.
The figure shows the soft, weighty modelling characteristic of the Master. The broad orange-red mantle is highlighted with gold, and its folds are rendered in long, even curves, while the body beneath has convincing volume. The circular fold over the belly is one of the motifs most often associated with this painter. Ursula Prinz has argued, however, that such motifs derive from shared models and fixed workshop schemes and do not in themselves prove the presence of a single hand. Whether the page is read as the work of one master or of a closely collaborating Trier workshop, it displays the same classicising calm and harmonious colour as the other evangelist portraits.
The Luke portrait completes the sequence of evangelist images with a figure of active authorship. The architecture is clear and balanced, the colour luminous, and the evangelist dignified yet animated by the movement of composition. The verse and the text on the book bind image and word together, and the possible presence of the Master’s own script gives the page particular documentary value. Like the other pages of the Sainte-Chapelle Gospels, it later served as a model at Echternach, carrying the classicising art of Egbert’s Trier into the next generation of Ottonian book painting.
Saint John Inspired: The Evangelist Portrait on Fol. 115v of the Sainte-Chapelle Gospels
This miniature introduces the Gospel of John and closes the sequence of four evangelist portraits that the Bibliothèque nationale attributes to the Master of the Registrum Gregorii. It follows the scheme of the preceding pages: an arch crowned by the evangelist’s symbol and a verse inscription, enclosing the evangelist enthroned. In one decisive respect it departs from them. Matthew, Mark and Luke are shown writing or preparing to write; John does not write at all. He looks upward, receiving inspiration. The final portrait thus becomes an image of revelation rather than authorship, in keeping with the traditional view of John’s Gospel as the most exalted and contemplative of the four.
The arch springs from two columns painted in pink with darker veining, imitating coloured marble, beneath blue foliate capitals of antique type. The arch itself is built of concentric bands: an outer gold band, a broad frieze of stylised leaves in blue and green, and an inner band of pink. The spandrels are painted in mauve and filled with gold vine scrolls ending in small trefoils and flowers, a richer ornament than on the other evangelist pages. Below the arch, there is no inner arcade as in Mark’s and Luke’s portraits. The evangelist sits directly against a plain blue ground, with a lighter horizon band near his feet. The simplification concentrates attention on the figure and on the vertical line connecting him to the eagle above.
The lunette, painted in pink, holds John’s symbol: a golden eagle with a gold halo, its wings raised and spread. The bird turns its head in profile and grips a closed book in one talon. Its plumage is rendered in fine strokes of ochre and gold, and its form is modelled with a sense of volume that makes it appear almost sculptural. Unlike the symbols on the other evangelist pages, which look outward, the eagle seems poised for flight. That poise suits both the creature traditionally associated with the soaring vision of John’s Gospel and the movement of the evangelist’s gaze toward it.
A purple band beneath the eagle carries a single hexameter in gold capitals:
More aquilae alta petit meritis verboque Iohannes,
“In the manner of the eagle, John seeks the heights by his merits and by his word.”
The verse explains the choice of the eagle as John’s symbol. As the eagle was believed to fly highest and to gaze directly at the sun, so John’s Gospel was held to rise to the contemplation of the divine Word, beginning not with Christ’s human genealogy but with his eternal origin: In principio erat Verbum. A second inscription, in white capitals on the blue ground above the evangelist, names him
Iohannes apostolus et evangelista, “John, apostle and evangelist.”
It is the only one of the four portraits to carry such a label in addition to the verse.
John is presented as a young, beardless man with long hair and a large gold halo, in keeping with the tradition that he was the youngest of the apostles. He sits in three-quarter view on a monumental gold throne studded with gems, its high back draped with a green cloth that falls in heavy folds. The throne’s sides are pierced with small arches and its posts crowned with golden knobs. A red cushion with an ornamented band lies on the seat, and his bare feet rest on an arcaded gold footstool. He wears a blue tunic and a rose-coloured mantle that sweeps across his lap in broad folds. In his right hand he holds closed books, left white, perhaps to suggest pages not yet written or because the gilding was never applied. His left hand is raised with the palm open, and his head is turned upward toward the eagle. The gesture and gaze express attentive reception.
To the right stands a tall lectern built like a small piece of architecture, a mauve pedestal with arched openings and mouldings. On its sloping desk there is no book, only an inkwell with a quill. The empty desk is eloquent. It shows the moment before writing, when the evangelist is still absorbed in the vision that his Gospel will record. The contrast with the preceding portraits, in which books lie open and pens move across the page, makes this the most contemplative image in the sequence.
The palette is fresh and luminous: the blue of the ground and tunic, the rose of the mantle and columns, the green of the drapery and leaf frieze, all enriched with gold. The modelling is soft and the forms full, with the circular folds on the upper arm and lap characteristic of the painter’s drapery. The figure has a calm monumentality, yet the turn of the head and the raised hand give it an inner movement that sets it apart from the other evangelists. Ursula Prinz has argued that such drapery schemes reflect shared models within a Trier workshop rather than proof of a single hand. Whatever the division of labour, the page displays the same classicising harmony as the rest of the book.
The John portrait brings the sequence of evangelists to a fitting climax. The architecture is simplified, the throne magnified, and the act of writing replaced by the moment of inspiration, so that the visual programme culminates in the most spiritual of the Gospels. Image and verse correspond closely: the upward gaze of the evangelist, the poised eagle and the hexameter about seeking the heights all express the same idea. Together with the portraits of Matthew, Mark and Luke, the page shows how the Trier painters varied a fixed formula to give each evangelist a distinct character. It also explains why the manuscript later served as a model at Echternach.
The Strahov Gospels in Prague (Strahov Library, DF III 3) show the Master in a different role, as the enricher of an older book. The text was written at Tours in the Carolingian period. In the tenth century, while the codex belonged to the church of Saint Martin in Trier, it received four full-page evangelist portraits by the Master, whose symbols have been compared with the enamels of Egbert’s goldsmiths. The manuscript probably reached the Premonstratensians of Strahov only in the thirteenth century. Here the Master’s art appears as a dialogue with the Carolingian past: an old and venerable book was modernised and honoured at once.
Strahov Gospels, fol. 2r: The Ownership Note of Saint Martin’s, Trier
Saint Matthew Writing: The Evangelist Portrait on Fol. 8v of the Strahov Gospels
This miniature belongs to the Strahov Gospels, a Gospel book whose text was written in uncial script, probably at Tours around 860. In the late tenth century the manuscript was in Trier, in the church of Saint Martin, as an ownership note on fol. 2r records:
Codex sancti Martini super litus Mosellae. Si quis eum abstulerit, anathema sit.
“The book of Saint Martin on the bank of the Moselle. If anyone takes it away, let him be anathema.”
There, four full-page evangelist portraits on purple-stained leaves were added, which are now attributed to the Master of the Registrum Gregorii. They were probably painted as separate leaves and bound into the older codex. The portrait of Matthew is the first of the series.
The page is entirely stained purple, and the miniature occupies a framed field within it, leaving wide purple margins. The field is divided into three horizontal zones: an upper register with the angel, a narrow purple band with a verse in gold capitals, and a large lower field in which the evangelist sits writing. There is no architectural frame of columns and arch, as in the evangelist portraits of the Sainte-Chapelle Gospels. The composition depends instead on the clear stacking of registers and on the contrast of coloured grounds: lilac above, purple in the middle and green below. The simplicity of the scheme concentrates attention on the figure and gives the page a calm, monumental order.
In the upper register, against a lilac ground, appears the angel, symbol of Matthew, shown half-length with outspread blue-grey wings and a large gold halo. He wears a white garment and holds a closed gold book, the Gospel entrusted to the evangelist below. On either side of him, gold inscriptions in capitals are now heavily abraded and cannot be read reliably in this reproduction. The angel’s frontal pose and direct gaze give him the character of a heavenly witness standing above the act of writing.
The purple band beneath the angel carries a line of gold capitals:
Hoc evangelium quod ponitur ordine primum, “This Gospel, which is placed first in order.”
The same words open the verse inscription on the Matthew portrait of the Sainte-Chapelle Gospels (Paris, BnF, lat. 8851, fol. 15v), which is attributed to the same painter. The parallel is significant evidence for the close connection between the two cycles. In the green field, gold capitals flank the evangelist’s halo. They can be read as
Matheus Haebraico scrips[it] … elo[quio],
stating that Matthew wrote in the Hebrew language, though part of the text is lost. The inscriptions together record the tradition that Matthew’s Gospel stands first in the canon and was originally composed in Hebrew.
Matthew sits in profile on a gold block throne with a red cushion, bent forward over his work. Unlike the elderly, bearded Matthew of the Sainte-Chapelle Gospels, he is shown young and beardless, with short brown hair and a large gold halo. He wears a white tunic and a deep purple mantle wrapped around his body and legs, and his bare feet rest on a blue-green footstool. He writes on a long sheet laid across the sloping desk of a lectern supported on a red turned stand, the end of the sheet hanging down below the desk. His intent posture, with head and shoulders curved over the page, conveys absorption in the act of writing. The figure has the weight and quiet concentration characteristic of the Master’s evangelists.
The palette is restrained but rich: the purple of the page and the mantle, the green of the ground, the white of the tunic, the red of the cushion and stand, and the gold of the halos, throne and inscriptions. The gold was applied as leaf. Technical study of the Codex Egberti identified the Master’s practice of applying gold leaf cut to shape and glued on after the painting was finished, and found the same practice in the Strahov Gospels and the Registrum leaves. The page has suffered considerably: the green ground is mottled with losses, the paint is abraded in several places, and the inscriptions in the upper register are largely illegible. A small parchment tab with Gothic script, a later finding aid, projects from the left edge of the leaf.
Comparison with the Matthew portrait of the Sainte-Chapelle Gospels is instructive. Both pages use the same opening verse and present the evangelist writing at a lectern beneath his symbol. The Strahov page, however, is simpler in structure, without the arch, columns and curtains of the Paris manuscript, and its figure is younger and more compact. These differences may reflect the smaller format of the older Carolingian codex into which the leaves were inserted, as well as a different stage in the painter’s development. The Strahov portraits have been described as an early work of the Master, though their exact place in his chronology remains debated.
The Strahov Matthew shows the Master working not on a new book but on an old and venerable one. The addition of purple leaves with evangelist portraits gave the Carolingian Gospel book a new splendour and brought it into line with the luxury manuscripts produced for Egbert’s Trier. In this the page reflects a broader attitude of the period, which honoured older books as precious relics of the Carolingian past while renewing them in a contemporary style. Its relationship with the Sainte-Chapelle Gospels makes it an important witness for the attribution and development of the Master’s work.
Saint Mark Writing: The Evangelist Portrait on Fol. 69v of the Strahov Gospels
This miniature introduces the Gospel of Mark in the Strahov Gospels, the Carolingian Gospel book written probably at Tours around 860 and later kept in the church of Saint Martin at Trier. There, in the late tenth century, four evangelist portraits on purple-stained leaves were added, now attributed to the Master of the Registrum Gregorii. The Mark portrait follows the same scheme as the Matthew portrait on fol. 8v: the symbol in an upper register, a verse in gold capitals on a purple band, and the evangelist at work in the main field. It falls at the transition between the two Gospels: according to the catalogue, Matthew’s Gospel ends on fol. 68r with the colophon
Explicit Evangelium secundum Matheum.
The leaf is entirely stained purple, and the image occupies a framed field with wide margins. The field is divided into three horizontal zones: the lion on a pale pink ground, the inscribed purple band, and the evangelist on a warm golden-orange ground. There is no architecture, so the figure appears against an open field of colour that lightens toward the top, suggesting luminous space rather than a defined interior. The arrangement is simple and clear, and the strong colour contrasts give the page its intensity: purple against pink, purple against gold, and the cool blues and violets of the figure against the warm ground.
In the upper register, the winged lion, symbol of Mark, stands in profile with its head turned and crowned with a gold halo. Its golden-brown body is modelled with fine strokes, its mane rendered in curling locks and its tail raised behind it. Its broad orange wings are spread and lifted, and one forepaw rests on a closed book with a small gold boss. The animal has a vivid, almost menacing presence, with open jaws and an alert eye, in keeping with the verse beneath it.
The purple band carries a single hexameter in gold capitals:
Marcum terribilis designat forma leonis, “The form of the terrible lion signifies Mark.”
The verse belongs to the tradition of short metrical tituli explaining the evangelist symbols. The lion was associated with Mark because his Gospel opens with the voice of one crying in the wilderness, likened to a lion’s roar, and the lion was also read as a figure of Christ’s Resurrection and royal power. The adjective terribilis conveys the awe-inspiring majesty of the symbol rather than mere ferocity.
Mark sits in three-quarter view on a violet block throne with a green cushion, his bare feet resting on a grey footstool. He is shown with a tonsure and short dark hair, beardless, his face turned slightly toward the viewer with a calm, attentive expression, and his head framed by a large gold halo. He wears a light blue tunic and a rose-coloured mantle wrapped around his body and legs. With his right hand he dips a quill into an inkwell placed on a small desk atop a tall stand. The stand has a turned shaft and a foliate capital of acanthus leaves. In his left hand he holds a long scroll, already inscribed with lines of script, which unrolls upward to rest on a lectern supported by a slender green column with gold bands. The figure thus links the two instruments of writing, ink and scroll, in a single continuous gesture.
The palette is warm and luminous: the golden-orange ground, the rose mantle, the light blue tunic and the violet throne, set within the purple of the page. The drapery is modelled with soft highlights, and a circular fold over the evangelist’s thigh gives volume to the body beneath. Such circular folds have often been treated as a signature of the Master. Ursula Prinz has argued instead that they derive from shared models within a Trier workshop. The figure has the calm weight and classical dignity characteristic of the evangelists associated with the painter, and the gold of the halo and inscription catches the light against the coloured grounds.
Comparison with the Mark portrait of the Sainte-Chapelle Gospels (Paris, BnF, lat. 8851, fol. 52v) reveals both continuity and difference. In both pages Mark dips his quill into an inkwell placed on a slender turned stand to his right, and in both the background is a warm ochre. The Paris Mark, however, is presented as a bishop in chasuble and pallium within an elaborate double architecture. The Strahov Mark wears the tunic and mantle of an antique author and sits against an open field of colour. The shared motifs support the attribution of both cycles to the same painter or workshop. The differences reflect the smaller format of the Strahov leaves and a more classical conception of the evangelist as author.
The Strahov Mark shows the Master adapting the evangelist portrait to the format of an older Carolingian book. The open composition, warm colour and calm figure create an image of quiet dignity, while the verse and the lion give it theological meaning. Together with the other three Strahov portraits, the page testifies to the renewal of a precious Carolingian manuscript in the classicising style of Egbert’s Trier. Its close relationship with the Sainte-Chapelle Gospels makes it an important point of comparison for understanding the work of the Master of the Registrum Gregorii.
Saint Luke in Contemplation: The Evangelist Portrait on Fol. 107v of the Strahov Gospels
This miniature introduces the Gospel of Luke in the Strahov Gospels. It is the third of the four portraits on purple-stained leaves that the Master of the Registrum Gregorii added to the Carolingian Gospel book while it was in the church of Saint Martin at Trier. It follows the end of Mark’s Gospel, which the catalogue records on fol. 106v. The page repeats the format of the Matthew and Mark portraits: the symbol in an upper register, a verse in gold on a purple band, and the evangelist in the main field. Within this shared structure it introduces a striking new conception: Luke is shown not writing but thinking.
The leaf is entirely stained purple, and the image occupies a framed field with broad margins. The upper register has a blue ground, the band beneath it is purple, and the main field is painted in a warm rose that lightens toward the top. Against this open, luminous ground the evangelist sits without architecture, flanked only by his stool on one side and his lectern on the other. The figure is placed slightly off centre, turned toward the right, so that the composition gains a gentle movement from the seated man to the open book he contemplates.
In the upper register, the winged ox, symbol of Luke, reclines against the blue ground. Its reddish-brown body is compact and solid, its horned head turned frontally and crowned with a gold halo, its brown wings raised behind it and its tail curling upward. It rests over a book, the Gospel it represents. The ox was associated with Luke because his Gospel opens with the priest Zacharias offering sacrifice in the Temple, and the animal of sacrifice was read as a figure of Christ’s Passion.
The purple band carries a single hexameter in gold capitals:
Lucas aetherei speciem tenet ore iuvenci,
“Luke bears in his countenance the likeness of the heavenly bullock.”
The end of the line is partly obscured in this reproduction, but the reading fits both the metre and the sense. The verse echoes the well-known lines of Sedulius’s Carmen paschale, in which Luke is said to hold the rights of priesthood “with the face of the bullock.” It thus continues the series of metrical tituli that accompany each Strahov evangelist, together with Marcum terribilis designat forma leonis on the Mark page.
Luke sits on a gold folding stool whose legs end in animal heads and clawed feet, with a red cushion patterned in gold, and his bare feet rest on a gold footstool. He is young and beardless, with short dark hair and a large gold halo. He wears a blue tunic and a green mantle that envelops his whole body, drawn up over his shoulders and wrapped around his legs. He rests his chin on his right hand, a gesture of reflection, and holds a small rolled scroll in his left. His gaze is fixed on the open book lying on a tall mauve lectern built like a small pedestal with mouldings and panels, from which a scroll hangs down. The pose derives from the ancient type of the thinker or philosopher. It presents the evangelist in the moment of meditation that precedes writing, absorbed in the text he is about to compose.
The palette is harmonious and subtle: the rose of the ground, the green of the mantle, the blue of the tunic and of the upper register, the gold of the stool, halos and footstool, all set within the purple of the page. The mantle is modelled in soft gradations of green, with folds that follow the bent body and convey its volume. The figure’s enveloping drapery and compact silhouette give it a quiet, inward-turned monumentality. Comparison with the Luke portrait of the Sainte-Chapelle Gospels (Paris, BnF, lat. 8851, fol. 75v) reveals two quite different conceptions of the same evangelist. In Paris, Luke is an elderly, bearded author caught in the act of composition, turning between two books beneath an elaborate architecture. In Prague, he is a young man in contemplation, seated on a folding stool in an open field of colour. The folding stool with animal-head terminals recalls the stool of the Matthew portrait in the Paris manuscript. The tall pedestal lectern with a hanging scroll belongs to the same repertory of furniture used in both cycles. The differences show the painter’s capacity to vary his types, while the shared motifs confirm the close relationship between the two series.
The Strahov Luke is one of the most poetic images associated with the Master of the Registrum Gregorii. By replacing the act of writing with a moment of meditation, the painter shifted attention from the physical labour of the scribe to the inner process of understanding and composition. The page thus enriches the cycle of evangelists with a contemplative note, anticipating the inspired upward gaze of John in the Sainte-Chapelle Gospels. Together with the other Strahov portraits, it testifies to the renewal of a Carolingian manuscript in the classicising style of Egbert’s Trier.
Saint John Writing: The Evangelist Portrait on Fol. 176v of the Strahov Gospels
This miniature introduces the Gospel of John and completes the cycle of four evangelist portraits that the Master of the Registrum Gregorii added to the Strahov Gospels while the Carolingian book was in the church of Saint Martin at Trier. Like the portraits of Matthew, Mark and Luke, it is painted on a purple-stained leaf and follows the same three-part structure: the symbol above, a verse in gold on a purple band, and the evangelist below. The Gospel it introduces closes the volume, ending on fol. 222v with the scribe’s plea
Ora pro me, qui legis, “Pray for me, you who read.”
The portrait thus opens the final and most exalted of the four Gospels.
The image occupies a framed field within the broad purple margins of the leaf. The upper register has a pale mauve ground, the inscription band is purple, and the main field is painted in a cool blue-violet. This cool ground differs from the warm golden and rose fields of the Mark and Luke portraits, giving the page a more solemn and otherworldly tone. Against it the evangelist sits frontally and almost symmetrically, with the lectern on one side balancing the composition. In the upper register, the eagle, symbol of John, is shown with its body frontal and its wings spread wide, its head turned in profile and crowned with a gold halo. Its feathers are rendered in olive and golden tones, and it stands over a book. The eagle’s heraldic frontality and spread wings convey the idea of soaring flight. It was associated with John because his Gospel was believed to rise above the others in contemplating the divinity of Christ, as the eagle was thought to fly highest and gaze directly into the sun.
The purple band carries a single hexameter in gold capitals:
Est aquila alta petens narrans divina Iohannes,
“John is the eagle seeking the heights, narrating divine things.”
The final letters are partly hidden in this reproduction, but the reading fits both the sense and the metre. The line echoes Sedulius’s verse on the evangelist symbols, More volans aquilae verbo petit astra Iohannes. It is a close parallel to the verse on the John portrait of the Sainte-Chapelle Gospels, More aquilae alta petit meritis verboque Iohannes. The two inscriptions share the image of the eagle seeking the heights but are worded differently, which suggests that the Trier painters drew on a common tradition of tituli while varying them from one book to another.
John sits frontally on a gold block throne with a green cushion, his feet resting on a green footstool. He is shown as an elderly man with long hair and a full grey beard, framed by a large gold halo, his gaze directed calmly toward the viewer. He wears a white tunic and a bright red mantle that falls across his lap in broad, softly modelled folds. In his left hand he holds an open book filled with lines of script, and with his right he raises a quill to its pages, writing as he sits. Beside him stands a tall mauve lectern shaped like a small pedestal with an arched niche, on whose sloping desk lie rolled scrolls and an inkwell. The figure combines the authority of an aged apostle with the activity of the author, presenting John as the witness who records the divine Word.
The palette is strong yet balanced: the bright red of the mantle stands out against the cool blue-violet ground, set off by the white of the tunic, the green of the cushion and footstool and the gold of the halo and throne. The drapery is modelled with soft gradations, and the folds over the knees give the seated body volume and weight. The frontal pose, the symmetry of the composition and the intensity of the red mantle make this the most monumental of the Strahov portraits.
Comparison with the John portrait of the Sainte-Chapelle Gospels (Paris, BnF, lat. 8851, fol. 115v) reveals a significant reversal of types. In Paris, John is young and beardless, looking upward toward the eagle and not yet writing, while Matthew is shown as an elderly bearded man. In Prague, Matthew is young and beardless, while John is an elderly bearded man writing in his book. The painter, or his workshop, clearly disposed of a repertory of figure types, young and old, contemplative and active. He combined them differently in each cycle, so that the two series form variations on a shared theme rather than copies of each other.
The Strahov John completes the cycle with an image of authority and witness. The frontal pose, the aged face and the act of writing present the evangelist as the guarantor of the Gospel’s truth, while the eagle and the verse point to the divine heights his text reaches. Together the four Strahov portraits show the Master renewing a Carolingian manuscript with images of great dignity and variety. They also constitute, alongside the Sainte-Chapelle Gospels, one of the most important groups of evangelist portraits attributed to the painter of the Registrum Gregorii.
Several further works complete the picture. The Lorsch Sacramentary (Chantilly, Bibliothèque du château, Ms. 40), made in Trier for the abbey of Lorsch around 975–980, is often placed among his earliest works, executed alongside the principal scribe of the Codex Egberti.
The Crucifixion in the Lorsch Sacramentary: Chantilly, Ms. 40, fol. 4v
This Crucifixion belongs to a sacramentary made in Trier for the Benedictine8 abbey of Lorsch, dated by the Biblissima record to around 975–980. It is one of the books in which the Master of the Registrum Gregorii is thought to have worked at an early stage of his career, alongside the principal scribe of the Codex Egberti. A sacramentary contained the prayers spoken by the celebrant at Mass, and the Crucifixion was the image traditionally associated with its central prayer, the canon. The full-page miniature therefore gives visual form to the sacrifice commemorated in the Eucharist.
The composition is strictly symmetrical and frontal. The cross rises in the centre from the green ground to the upper edge of the frame, dividing the field into two halves. Mary stands on the left and John on the right, each turned slightly toward the cross, and the roundels of the Sun and the Moon flank the upper arm. The background is divided into a lilac sky with faint horizontal bands above the crossbar and a deep blue field below, ending in a strip of green ground scattered with small plants. The arrangement is spare and solemn: few figures, clear axes and generous intervals of colour, so that each element can be read distinctly.
Christ hangs on a gold cross outlined in a darker tone, his arms extended straight along the crossbar and his hands fixed with nails. His head, framed by a halo inscribed with a cross, inclines toward his right, the side of his mother. He has long dark hair and a beard, and his eyes appear to be still open, looking downward. His body is pale and carefully modelled. The chest is broad, the abdomen rounded and prominent, and the legs long and slender, with the feet placed side by side on the upright of the cross. An orange loincloth is knotted at the waist and falls in folds to the knees. The figure combines a dignified calm with an attention to the weight and volume of the body that recalls the Master’s classicising figures. Christ appears less as a victim than as a serene king on the cross, in keeping with early medieval conceptions of the Crucifixion.
Gold inscriptions identify the figures. Above the cross, letters with suspension marks read
IHS XPS DNS NR,
standing for
Iesus Christus Dominus noster, “Jesus Christ our Lord.”
Beside Mary, short columns of capitals spell
Sancta Dei genitrix Maria, “Holy Mary, Mother of God.”
Beside John, the inscription reads
Sanctus Iohannes apostolus, “Saint John the Apostle.”
The labels place the image within a liturgical and theological framework, naming Christ as Lord and Mary as Mother of God, the title affirmed by the Council of Ephesus.
Mary stands at the left, wearing a white veil and a purple mantle over a light blue gown. Her head is bowed toward the cross in an expression of quiet grief, and her right hand is drawn toward her body in a gesture of sorrow. The mantle falls in long, softly modelled folds that give her figure height and gravity. Her restraint conveys mourning without dramatic excess, in keeping with the calm tone of the whole composition.
John stands at the right as a young, beardless man with short hair and a gold halo. He wears a pink tunic and a green mantle draped over one shoulder and around his body. In his left hand he holds a closed book with a jewelled cover, identifying him as evangelist, and he raises his right hand with the palm open toward the cross, a gesture of witness. His bare feet stand firmly on the green ground. His pose mirrors Mary’s on the opposite side, and the two figures together frame the cross as witnesses of the sacrifice.
Above the crossbar, two roundels contain personifications of the Sun and the Moon. The Sun, on the left, appears as a young man with a radiant halo against an orange-gold ground. The Moon, on the right, appears as a veiled woman beneath a crescent against a pale silvery ground. The motif derives from Late Antique imagery and was common in Carolingian and Ottonian Crucifixions. It recalls the darkness that covered the earth at Christ’s death and presents the whole cosmos as witness to the event. Placed on either side of the cross, the two roundels extend the symmetry of the earthly witnesses into the heavens.
The miniature shows features associated with the Master of the Registrum Gregorii: the calm, balanced composition, the restrained gestures, the soft modelling of drapery and bodies, and the luminous, carefully harmonised colour. The rounded abdomen of Christ and the long, smooth folds of the garments recall the figure style of his later works. The clear spatial relationship of the figures standing on a common ground anticipates his more ambitious constructions of space. If the attribution and dating are correct, the page shows the classicising manner of Egbert’s Trier in an early, still relatively simple form. It provides an important starting point for understanding the development of the painter’s art.
Te igitur: The Canon Initial of the Lorsch Sacramentary, Chantilly, Ms. 40, fol. 5r
This page opens the canon of the Mass, the central and unchanging prayer of the Eucharistic liturgy, which begins with the words
Te igitur clementissime Pater, “Therefore, most merciful Father.”
It faces the full-page Crucifixion on fol. 4v, so that the two pages form a single opening: the image of Christ’s sacrifice on the left and, on the right, the first words of the prayer in which that sacrifice is commemorated. The page contains only the two opening words, written in monumental letters, with the rest of the prayer following on the next pages. The sacramentary was made in Trier around 975–980 for the abbey of Lorsch, and its decoration has been associated with the early activity of the Master of the Registrum Gregorii.
The initial T dominates the page. Its crossbar is a broad gold band ending in small triangular terminals filled with interlace, and its stem descends to a flared foot. Down the centre of the stem runs a narrow panel of silver-white interlace, interrupted at mid-height by a gold collar. The letter is outlined throughout in a fine orange line, which sharpens the gold against the pale parchment. Its proportions are classical and monumental: the T stands firm and legible, a letter before it is an ornament.
From the stem of the T, gold acanthus scrolls spring out symmetrically on both sides. They curl into four roundels, two beneath the crossbar and two lower down, each ending in a rosette at its centre and sending out small leaves and tendrils along its edges. The roundels are filled with coloured grounds: violet in the upper pair, turquoise in the lower pair, each enlivened with fine hair-lines in lighter and darker tones. The foliage is crisp and fleshy, with leaves that curl back on themselves, and the symmetry of the two halves gives the letter the balance of a heraldic emblem. The vegetal growth seems to issue from the stem itself, as if the letter were a living tree.
The rest of the opening words is written in gold capitals. An E stands to the right of the stem’s foot, completing Te, and beneath it the word IGITUR runs across the width of the initial in letters of classical proportion. The capitals are tall and well spaced, with fine serifs and a clear contrast of thick and thin strokes. Their measured rhythm contrasts with the exuberance of the vine scrolls above, so that the page moves from ornament to legible script.
The palette is restrained: gold, violet, turquoise and the orange of the outlines, set on bare parchment. Unlike the opening of the Sainte-Chapelle Gospels, there is no purple panel behind the initial, and the letter stands directly on the cream surface of the page. This gives the composition lightness and clarity, and lets the gold stand out with particular brilliance. Letters from the other side of the leaf show faintly through the parchment, a reminder of the material reality of the book.
The initial T of the Te igitur had a special significance in early medieval sacramentaries. Its shape recalls the cross, and in many books the letter was elaborated into an image of the Crucifixion, a development that eventually gave rise to the full-page Crucifixion placed before the canon. In the Lorsch Sacramentary the two are kept distinct but set side by side, the painted Crucifixion on the left and the ornamental T on the right. The opening thus presents the cross twice, once as image and once as letter. The vine scrolls springing from the stem may evoke the cross as the tree of life, though the page itself carries no inscription that makes this explicit.
The initial belongs to the same family of gold vine-scroll letters found in the Sainte-Chapelle Gospels (Paris, BnF, lat. 8851), where the great B opening Jerome’s letter to Damasus shows gold scrolls on coloured grounds and interlace-filled bands. The Lorsch T is simpler and more open, without the purple panel and with fewer, larger scrolls, consistent with an earlier stage in the development of this type of ornament. Whether the Master executed the ornamental initials himself or directed collaborators is not established, so the caption names the Trier workshop as well.
The Te igitur page combines liturgical function, theological meaning and decorative splendour. It marks the most solemn moment of the Mass and gives the opening words of the canon the dignity of a monument. With the facing Crucifixion, it forms one of the most important openings of the Lorsch Sacramentary, showing how in Egbert’s Trier image and letter were combined to honour the central mystery of the Eucharist. As an early work associated with the Master of the Registrum Gregorii, it also illustrates the origins of the gold vine-scroll initial that would reach its fullest development in the Sainte-Chapelle Gospels.
A sacramentary in Paris (BnF, lat. 10501) received initial pages and frames from his hand. In the small Egbert Psalter in Trier (Hs. 7/9), a bilingual Latin and Greek book made for the archbishop’s private devotion, the prologue page, an initial page and the opening text page are attributed to him. This book must be distinguished from the more famous Egbert Psalter in Cividale, which was made at Reichenau and is not his work. Single leaves with the evangelist Mark, with Saint Willibrord and with an Annunciation have also been associated with the Master, though in the case of the Willibrord leaf it is the script on the reverse that is securely his and the painting remains disputed.
The Manchester Gospels: A Luxury Gospel Book for Otto III
The Gospel book in the John Rylands Library, Manchester (Latin MS 98), stands at the far end of the career traditionally reconstructed for the Master of the Registrum Gregorii. The library’s catalogue describes it as made for the Emperor Otto III between 996 and 1002, possibly by the Trier painter himself. If the attribution holds, it is the last great manuscript associated with him, and it shows that he outlived his patron Archbishop Egbert, who died in 993, and went on to work for the imperial court.
The book has not come down intact. Some of its frontispieces have been cut out, and the surviving decorated pages are therefore the principal evidence for its programme. These are the opening of Jerome’s letter to Pope Damasus on fol. 1v and the four Gospel incipits on fols. 16r, 65r, 98r and 154r. Each is a single, self-contained panel in which letters, ornament and frame are designed together. Because the images that once accompanied them are lost, these pages carry more weight than they would in a complete book.
The imperial character of the manuscript is clearest on the Matthew page, where four medallions in the frame are each inscribed Otto imperator augustus. The page ties the sacred text to the person for whom the book was made. The other pages express the same character through material splendour: gold on deep purple, burnished letters and frames conceived as goldsmith’s work. The purple ground recalls the stained parchment of Late Antique and imperial luxury books, and it suits a Gospel book made for an emperor.
The book is closely related to the Sainte-Chapelle Gospels (Paris, BnF, lat. 8851), which is also associated with the Master’s circle. Both manuscripts open Jerome’s Novum opus with a monumental initial B, and both open Matthew with an LI monogram framed by medallions. The comparison is one of the clearest ways to measure what the Manchester book keeps and what it changes. It retains the purple ground, the gold capitals and the idea of the initial as the dominant element. It replaces the vegetal scrolls of the Paris B with animal interlace, and it isolates each panel within an elaborate jewelled frame.
Across the four Gospels the decorators follow a consistent principle of variation within a shared system. Each incipit builds its words around a monumental initial on a purple panel. Matthew uses an LI monogram with imperial medallions, Mark a single vertical I bound by knots of interlace, and Luke a rounded Q with gem-like geometric squares. John, the most theologically ambitious, places the Lamb of God at the centre of an IN monogram and the four evangelist symbols on the axes of the frame. Small notes in the margins of the Mark and John pages record Eusebian concordance references, which show that the luxury book was also equipped for practical use.
The attribution to the Master has been doubted, and the pages are best described as the work of his workshop or close followers. The quality and coherence of the decoration nonetheless suggest a single guiding conception. The manuscript reached Cologne soon after it was made and shaped the illumination produced there, so that later Cologne copies preserve an idea of the lost images. Through it, the decorative language of Trier passed into the next phase of Ottonian book painting. The following sections examine each of the surviving pages in turn.
Beatissimo papae Damaso: The Opening Page of the Manchester Gospels, Latin MS 98, fol. 1v
This page opens the book with the beginning of Jerome’s letter to Pope Damasus, Novum opus, the preface in which Jerome presented his revision of the Latin Gospels. The same text opens the Sainte-Chapelle Gospels (Paris, BnF, lat. 8851, fol. 3r), and the comparison between the two pages is one of the clearest ways to measure the relationship between the two manuscripts.
The display panel carries the address of the letter:
Beatissimo papae Damaso Hieronimus, “To the most blessed Pope Damasus, Jerome.”
The words are distributed around the great initial. E and A stand above the bowl, T, I and S flank its base, and the rest follows in two lines of gold capitals: SIMO PAPAE DA / MASO HERONIMUS. The spelling HERONIMUS, without the first I, is a variant form of Jerome’s name; it is as written on the page and need not be corrected in quotation. The opening words of the letter itself, Novum opus, must have followed on the facing or next page.
The initial B dominates the panel. Its shaft rises in a broad gold band and curls at the top into a knotted loop that breaks through the upper edge of the frame, a bold gesture that ties letter and border together. The bowl is a large, almost circular form joined to the shaft by gold interlace knots on either side and closed at the bottom by a small foliate finial. Within the bowl, on a green ground scattered with white dots and fine lines, a gold beast with pointed ears, a staring eye and open jaws emerges from a dense knot of interlace. Its body dissolves into intertwined bands ending in curling leaves. The creature is not a separate figure placed inside the letter but part of its ornamental structure, so that animal, interlace and foliage merge into a single living pattern.
Around the initial, the smaller letters E, A, T and S are built of gold with coloured fills of green, lilac and white, and are themselves decorated with small interlace and foliate motifs. The I and the two lines of display capitals beneath are in plain gold, with clear, regular strokes and classical proportions. Small white and gold sprays of foliage are scattered across the purple ground in the spaces between the letters, enlivening the surface without crowding it. The careful fitting of letters around the initial shows that the panel was conceived as a single composition of script and ornament.
The panel is enclosed by a rich, multi-layered frame. An inner gold band and a lilac border with gold vine scrolls surround the purple field. Outside these, a darker green border carries gold acanthus-like foliage, and at the top and bottom a frieze of gold palmettes appears on a dark ground. The corners are marked by orange-red squares holding gold and white rosettes, and outside the frame leaf-shaped finials project from the four corners. The layering of bands in different colours, each with its own ornament, gives the frame the character of a goldsmith’s mount, enclosing the text like a precious stone.
The palette is dominated by gold set against deep purple, with accents of green, lilac, orange-red and white. The purple ground of the panel recalls the stained parchment of imperial and Late Antique luxury books, appropriate to a manuscript made for an emperor. The green of the bowl and the coloured fills of the lesser letters are applied with fine highlights and dots, and the gold is laid in broad, burnished areas that catch the light. The parchment outside the panel is left bare, so that the decorated rectangle stands out with the intensity of an inlaid plaque.
The Sainte-Chapelle Gospels open the same text with a monumental B whose shaft and bowls are filled with gold vine scrolls on coloured grounds, set in a tall purple panel beside a column of gold text. The Manchester page shares the purple ground, the gold capitals and the conception of the initial as the dominant element. It differs in two important respects. The decorated panel is enclosed by an elaborate frame and isolated on its own page, and the vegetal scrolls of the Paris letter give way to animal interlace, with a gold beast at the heart of the bowl. These differences may reflect a later stage in the development of the Trier workshop, a different set of models, or the hand of a different painter. The attribution of the Manchester Gospels to the Master has been doubted, and the page is best described as belonging to his circle or workshop.
The page combines the gold and purple splendour of imperial manuscripts with an inventive interplay of animal, interlace and plant motifs, and its frame shows a taste for layered, jewel-like ornament. Since the Manchester Gospels reached Cologne soon after completion and shaped the illumination there, pages like this one helped to carry the decorative repertory of Trier into the next phase of Ottonian book painting.
Liber generationis: The Matthew Incipit of the Manchester Gospels, Latin MS 98, fol. 16r
This page opens the Gospel of Matthew in the Gospel book made for Otto III between 996 and 1002 and now in the John Rylands Library. The library’s catalogue describes the book as possibly the work of the Master of the Registrum Gregorii. The page presents the first words of the Gospel,
Liber generationis Iesu Christi filii David,
“The book of the generation of Jesus Christ, the son of David” (Matthew 1:1), reduced to a monumental monogram and a few gold letters. It thus belongs to the same tradition as the Matthew incipit of the Sainte-Chapelle Gospels (Paris, BnF, lat. 8851), with which it invites close comparison.
The dominant element is a monogram formed by an L and an I. The L runs down the left side of the panel and turns along the bottom, its shaft and foot filled with panels of white interlace and its ends knotted into gold loops. The I rises in the centre as a tall gold stem, also filled with interlace, and its base crosses the foot of the L, so that the meeting of the two letters forms a small cross. The letters are firmly drawn and perfectly legible, yet their terminals dissolve into knots and interlace, giving the structure a sense of movement.
From the stem of the I, gold scrolls spring out symmetrically on both sides and curl into four roundels, two above and two below, each holding a gold rosette on a blue ground dotted with white. Behind the scrolls, fields of green set off the gold against the mauve of the panel. The upper and lower pairs of scrolls are joined at the centre by horizontal sprays, creating a cross-shaped arrangement around the I. The vegetal growth, emerging from the letter itself, recalls the scrolls of the Lorsch Sacramentary’s Te igitur and of the Sainte-Chapelle initials, but here it is organised more strictly around the central axis.
The remaining letters of the incipit are distributed in the spaces left by the monogram. B, E and R appear at the top, completing LIBER. G, E, N and E are placed down the right side and above the foot of the L, and RATIONIS runs along the bottom of the panel, completing GENERATIONIS. The letters are small, gold and widely spaced, so that the reader must search for them around the great monogram. The arrangement makes the reading of the page a slow and deliberate act, appropriate to the solemn opening of the Gospel.
The panel is enclosed by a multi-layered frame of great richness. Within an outer border of orange-red with gold tendrils run bands of gold, pink and lilac decorated with stylised plant stems in green, lilac and white. Blue squares at the four inner corners hold gold and white foliage, and gold foliate crests project from the midpoints of the sides. Gold rosettes on stems project diagonally from the outer corners. The layering and the projecting ornaments give the frame the character of a goldsmith’s work, comparable to the jewelled covers that luxury Gospel books of the period received.
Four blue squares placed at the midpoints of the frame hold gold medallions, each containing the bust of a young, beardless man with short hair, wearing a garment of white or green. The faces turn in slightly different directions, giving variety to the series. Around each bust runs a tiny inscription, too small to read in this reproduction. According to the John Rylands Library’s catalogue, each medallion is inscribed Otto imperator augustus, “Otto, emperor, augustus.” The repeated portrait of the emperor surrounding the opening of the Gospel binds the sacred text to the person of the ruler for whom the book was made, presumably Otto III.
The Sainte-Chapelle Gospels also open Matthew with an LI monogram framed by eight images: four evangelist symbols at the corners and four ruler medallions at the midpoints of the sides. In the Paris manuscript the busts have been read, following Carl Nordenfalk, as four different members of the Ottonian house, although that reading is contested. In Manchester, by contrast, the same name in all four inscriptions suggests a repeated image of a single emperor rather than a dynastic sequence. The evangelist symbols are absent, and the frame has become more elaborate and jewel-like. The two pages are clearly related in conception, which supports the association of the Manchester book with the Master’s circle. The differences show how the formula could be adapted to a new patron and a new political moment.
The page is one of the key witnesses to the Manchester Gospels’ imperial character. The monogram honours the opening of the Gospel, the vine scrolls and frame give it the splendour of precious metalwork, and the medallions place the emperor at the four cardinal points of the text. The attribution of the book to the Master of the Registrum Gregorii has been doubted. If it holds, the page shows the painter or his workshop working for Otto III himself, years after Egbert’s death. Since the manuscript reached Cologne soon after completion and influenced the illumination produced there, its incipit pages also played a part in the transmission of the Trier repertory to the next generation of Ottonian book painting.
Initium: The Mark Incipit of the Manchester Gospels, Latin MS 98, fol. 65r
This page opens the Gospel of Mark in the Gospel book made for Otto III and now in the John Rylands Library, which the library’s catalogue describes as possibly the work of the Master of the Registrum Gregorii. The first words of Mark’s Gospel,
Initium evangelii Iesu Christi filii Dei,
“The beginning of the Gospel of Jesus Christ, the Son of God,” are here reduced to a single word, Initium, built around a monumental initial I.
The word INITIUM is composed with remarkable economy. The great initial I occupies the centre of the panel, while the remaining letters are placed in the four corners in gold capitals: NI and TI above, V and M below. Read in order, they spell I-NI-TI-V-M. The arrangement uses the symmetry of the page to construct the word, so that text and ornament form a single balanced design. The reader must assemble the word by moving the eye from the centre to the corners, an act that gives the opening of the Gospel a contemplative quality.
The initial I rises vertically through the whole panel. Its stem is not solid gold but left partly in bare parchment, bound by gold bands that interlace across it. At top and bottom, the letter ends in dense knots of gold interlace that break through the frame and spread onto the borders, so that the letter literally binds the frame together. The stem itself is the axis of the entire composition, around which every other element is arranged in mirror symmetry.
From the stem of the I, gold scrolls spring out symmetrically, curling into four roundels, two above and two below. Each holds a gold rosette on a lilac ground dotted with white. At the centre, the scrolls enclose an oval field of green crossed by smaller gold tendrils and leaves. The scrolls end in small trefoils and leaf tips that fill the purple ground with a rhythmic pattern of curves. The combination of interlace knots and vegetal scrolls recalls the repertory of the Matthew incipit on fol. 16r, but here the emphasis falls on a single vertical letter rather than on a two-letter monogram.
The panel is enclosed by a frame of several bands: an outer orange border, gold bands and a green band decorated with gold interlace. At the four corners, lilac acanthus leaves with white veins fold diagonally over the frame. Beyond them, heart-shaped gold finials on slender stems project outward into the margin. At the midpoints of the sides, gold interlace knots break across the borders, echoing the knots of the initial. The frame is simpler than that of the Matthew incipit, without medallions, but its projecting leaves and finials give it the same character of a jewelled mount.
A short note in small minuscule is written in the right margin, beside the frame. Letters that seem to stand for Mark, Matthew and Luke can be distinguished, followed by numerals. The note appears to record the corresponding sections in the other Gospels according to the Eusebian system of concordance, which the canon tables of a Gospel book were designed to support. Its exact reading is uncertain, but its presence shows that the luxury book was also equipped for practical use in comparing the Gospel texts.
The palette is restricted but intense: gold dominates, set against the deep purple of the panel, with the green of the central oval and the borders, the lilac of the roundels and corner leaves, and the orange of the outer frame. The bare parchment of the stem introduces a pale accent at the heart of the composition. The gold is laid in broad, burnished areas that catch the light, while the coloured grounds are enlivened with white dots and fine lines. The overall effect is that of a precious object: a page conceived as a panel of enamel and goldsmith’s work.
The Mark incipit shows how the decorators of the Manchester Gospels varied their repertory from one Gospel opening to the next. The Matthew page, with its LI monogram and emperor medallions, emphasises imperial patronage. The Mark page, without figures, concentrates entirely on the abstract beauty of letter and ornament, building a word out of symmetry and gold. Its interlace knots, vine scrolls and jewelled frame belong to the decorative language of Trier, and its rigorously centred design shows the classicising sense of order characteristic of the Master’s circle. Since the attribution of the Manchester Gospels to the Master has been doubted, the page is best seen as the work of his workshop or close followers. Its influence on the illumination of Cologne helped to carry that language into the eleventh century.
Quoniam quidem: The Luke Incipit of the Manchester Gospels, Latin MS 98, fol. 98r
This page opens the Gospel of Luke in the Gospel book made for Otto III between 996 and 1002 and now in the John Rylands Library, which the library’s catalogue describes as possibly the work of the Master of the Registrum Gregorii. Luke’s Gospel begins with a prologue in which the evangelist explains his purpose:
Quoniam quidem multi conati sunt ordinare narrationem,
“Forasmuch as many have taken in hand to set forth in order a narrative” (Luke 1:1). The page presents only the first two words of this sentence, Quoniam quidem, built around a monumental initial Q. It is the third of the Gospel incipits in the manuscript, after the Matthew page on fol. 16r and the Mark page on fol. 65r.
The initial Q dominates the panel. Its bowl is a large oval of gold, outlined in orange and segmented by small bands, and its tail descends as a straight vertical stem to the lower frame, giving the letter the form of an ornamental mirror or a processional standard. Within the bowl, a green field holds a symmetrical tree of gold vine scrolls. Gold rosettes and small white quatrefoils mark the centres of the curls, and lilac grounds lie behind the lower scrolls. Two gold rosettes project from the left and right edges of the bowl, as if the vegetal growth were bursting through the letter. The stem is filled with a white scroll pattern on a reserved ground, a lighter echo of the gold ornament above.
The rest of the two words is written in gold capitals in the purple field on either side of the stem: UONI and AM on the first line, QUI and DEM on the second. With the initial Q they spell QUONIAM QUIDEM. The letters are well proportioned, with a mixture of capital and rounded uncial forms, and small white sprigs of foliage are scattered between them. The division of the words by the stem of the Q creates a balanced, almost heraldic arrangement, as the earlier incipits did.
The purple panel is not framed by a simple line. Its edges are stepped in successive zigzag bands of lilac and white, producing an effect of serrated or crenellated borders. This device, not found on the Matthew and Mark incipits, gives the panel a shimmering edge and enhances the impression that the purple field is a precious inlay set into the frame. The vertical stem of the Q runs straight through these bands to the bottom border, binding the letter to the frame as the knots of the Mark initial did.
The frame consists of an outer orange border, broad gold bands and a white band filled with gold interlace. At the midpoints of the sides, bevelled square fields project slightly beyond the frame, each holding a geometric motif. The upper and lower squares carry a saltire pattern in lilac and orange on a dark ground with white dots, and the side squares hold eight-pointed stars in lilac and orange on green. Heart-shaped gold finials on slender stems project diagonally from the outer corners. The bevelled squares, painted in perspective, imitate the settings of gems on a metal mount and recall the jewelled covers of contemporary Gospel books.
The palette combines gold with deep purple, green, lilac, orange and white. The gold is laid in broad, burnished areas, and the crisp orange outlines give definition to every scroll and band. The green field of the bowl, the lilac of the stepped edges and the varied colours of the geometric squares create a rich but controlled harmony. The page has been preserved in good condition, so that the brilliance of the gold and the subtle gradations of the coloured grounds can still be appreciated.
Seen together, the three incipits of the Manchester Gospels show a consistent principle of variation within a shared system. Each page builds its words around a monumental initial set on a purple panel, surrounded by a jewelled frame with projecting finials. The Matthew page combines an LI monogram with four imperial medallions. The Mark page rises around a single vertical I bound by interlace knots. The Luke page centres on a Q whose oval bowl and straight stem create a new, rounded silhouette, with geometric gem-like squares in place of medallions or knots. The repertory of vine scrolls, interlace and gold capitals remains constant, while the structure and the frame change from page to page.
The Luke incipit is one of the most elegant pages of the Manchester Gospels. Its rounded initial, symmetrical vine tree and gem-like frame display the decorative language of Trier at a refined and mature stage. The attribution of the manuscript to the Master of the Registrum Gregorii has been doubted, and the page may be the work of his workshop or close followers. Its quality and coherence with the other incipits nonetheless show a single guiding conception behind the book’s decoration. Through the manuscript’s early arrival in Cologne, pages like this one helped to shape the ornamental vocabulary of Ottonian book painting in the eleventh century.
In principio erat Verbum: The John Incipit of the Manchester Gospels, Latin MS 98, fol. 154r
This page opens the Gospel of John, the last of the four Gospel incipits in the book made for Otto III between 996 and 1002 and now in the John Rylands Library, which the library’s catalogue describes as possibly the work of the Master of the Registrum Gregorii. It presents the first words of the Gospel,
In principio erat Verbum, “In the beginning was the Word” (John 1:1).
The opening sentence of John’s Gospel was among the most venerated texts of the medieval liturgy, and its incipit is here given the most theologically ambitious decoration of the four. Beyond the imperial medallions of the Matthew page, this is the only incipit in the manuscript to carry sacred figures: the evangelist symbols are set into the frame, and the Lamb of God is placed at the heart of the monogram itself.
The words are arranged around a monogram of the letters I and N, the first two letters of In. Gold capitals spell PRINCIPIO across the top of the panel, divided by the stem of the I into PRIN and CIPIO, and ERAT VERBU at the bottom, the final M of Verbum indicated by a suspension stroke over the U. The capitals are firm and regular, with a mixture of square and rounded forms, and their placement in the corners of the panel frames the monogram symmetrically.
The I rises as a tall gold stem through the centre of the panel, filled with a narrow band of white interlace. The N is built around it: its two uprights are filled with dense gold interlace and curling foliage, and its diagonal is a broad band of white interlace running from upper left to lower right, crossing behind the I. The interplay of gold and white, of solid bands and woven patterns, creates a rich surface while keeping the letters legible. The monogram thus combines the clarity of a classical letter with the intricacy of interlace ornament.
At the centre of the monogram, where the I meets the diagonal of the N, a small square holds a white lamb on a gold ground, with a halo and a slender staff. The Lamb of God refers to John the Baptist’s words in this Gospel, Ecce agnus Dei, “Behold the Lamb of God” (John 1:29), and to Christ’s sacrifice. Its placement at the centre of the opening words, In principio erat Verbum, unites the eternal Word with the sacrificial Lamb, the beginning of the Gospel with its fulfilment. The image makes the incipit a statement of the central mystery of the Christian faith.
Four square fields placed on the axes of the frame hold the symbols of the evangelists on gold grounds. The eagle of John stands at the top with a book at its feet, the winged ox of Luke at the left and the winged lion of Mark at the right, each with a book, and the angel of Matthew at the bottom, holding a scroll and raising one hand. Together with the central Lamb, the squares form a great cross across the page, with Christ at its centre and the four Gospels at its arms. The frame consists of several bands: an inner green band with small gold arrowheads at the corners, a broader band of blue-grey with white foliate motifs, and outer bands of gold outlined in orange. The squares with the evangelist symbols project beyond the frame and are flanked by gold foliate crests at the top, bottom and sides. Gold fleur-de-lis finials project diagonally from the outer corners. As in the other incipits, the frame has the character of a jewelled setting. Here the “gems” are images of the evangelists rather than abstract motifs or imperial portraits.
In the right margin, a short note in small minuscule reads
Io I / Mt I / Lu XIIII.
It records the opening section of John (section I) and its parallels in Matthew (section I) and Luke (section XIIII) according to the Eusebian system of concordance, used with the canon tables to compare passages across the Gospels. A similar note accompanies the Mark incipit on fol. 65r. These small annotations show that the imperial luxury book was also equipped for the practical study of the Gospel text.
The John incipit brings the sequence of Gospel openings in the Manchester Gospels to a climax. Where the Matthew page honoured the emperor with four medallions, and the Mark and Luke pages concentrated on the abstract splendour of letter and ornament, the John page places Christ himself at the centre, as the Lamb, surrounded by the four Gospels. The page combines the decorative language of Trier with a carefully conceived theological programme. The attribution of the manuscript to the Master of the Registrum Gregorii remains debated, but the coherence of the incipit sequence shows a single guiding mind behind its design. Through the book’s early arrival in Cologne, this vision of the Gospel as a jewelled and theologically ordered whole passed into the illumination of the eleventh century.
Beyond the Book: Charter, Enamel and Ivory
Attempts to extend the Master’s activity beyond manuscripts reach the edge of what the evidence can bear. Hoffmann attributed to him the painted decoration of the so-called marriage charter of Empress Theophanu (Wolfenbüttel, Niedersächsisches Landesarchiv, 6 Urk 11), dated 14 April 972. It is a purple scroll nearly one and a half metres long, written in gold, whose painted roundels of paired animals Hoffmann related to a Sasanian silver model. If correct, the attribution would place the Master’s activity before Egbert’s accession and at the very centre of imperial ceremonial. It would also stretch his career over roughly three decades, and it should therefore be treated with caution.
Nordenfalk went further still, attributing to him an ivory of Saint Nazarius in Hanover, a Madonna in Mainz and a Presentation in the Temple in Berlin. Real affinities link the Master’s painting with the enamels of Egbert’s workshop, and his technique with gold leaf points in the same direction. A demonstrated activity as goldsmith or ivory carver, however, has not been established, and these ascriptions belong to the speculative margin of the oeuvre rather than to its core.
The Sources of a Classicising Style
The Master’s classicism has been admired since the earliest studies of Ottonian painting, and the 1928 survey of Ottonian book illumination described it in terms that remain apt. That survey praised the group’s noble calm, long contours drawn in even curves, soft modelling without harsh contrasts of light and shade, a light and at times almost pale colour, restrained gestures and a relatively correct perspective. It concluded that this disposition, though nourished by antique and antiquising models, corresponds to no single model and reveals an independent artistic personality.
The specific sources identified since then bear out that judgement. Capitals in his architecture follow antique forms. The roof construction of the Gregory leaf has been related to the dedication image of the Gero Codex, from the Reichenau circle, whose initials are also close to his. The evangelists of the Sainte-Chapelle Gospels look both to classical figure types and to the Ada Gospels of Charlemagne’s court school, which was then kept at Saint Maximin in Trier. The diptych of the Registrum, as Nordenfalk showed, reworks a Byzantine composition. Contact with Byzantine art through the circle of Empress Theophanu is plausible, but the Niketas Bible is the only Byzantine model firmly identified.
What emerges is not an imitator but a painter who absorbed Late Antique, Carolingian and Byzantine sources and fused them into a coherent personal language. Trier, with its Roman ruins and its Carolingian libraries, offered him an exceptional store of models, but it was his synthesis that made them speak anew.
From Genius to Workshop: The Historiography
The modern literature on the Master falls into three broad phases. The first constructed the artist on stylistic grounds, from the early twentieth-century convenience name to the mid-century analyses, Nordenfalk’s 1950 essay above all, of the treatment of space in the two Registrum leaves, which placed him at the summit of Ottonian painting. The second refined the picture through palaeography, political history and technical study.
It is represented chiefly by Nordenfalk’s later work, including his chronology of 1972 and his study of the Registrum of 1985, and by Hoffmann’s Buchkunst und Königtum im ottonischen und frühsalischen Reich of 1986. These studies proposed a career with an early phase connected with Lorsch and Trier, a possible interlude at Reichenau, a mature phase in Trier and a late phase extending beyond 996.
The third phase has opened only recently and challenges the premise on which the first two were built. In her monograph Gregormeister. Die ottonische Buchmalerei in Trier und ihre kunsthistorische Galionsfigur, published in 2026 after a Kiel dissertation, Ursula Prinz examines the luxury manuscripts of Egbert’s Trier as material objects within their ecclesiastical and political contexts. She argues that the “Gregory Master” is above all a convenience name, and that the model of a single master owes much to a lingering cult of artistic genius. In her view the evidence is better explained by a group of artists who worked closely together and used the same models. Fixed schemes for drapery and flesh tones, and recurrent motifs such as the circular fold on the belly, derive from shared models and need not prove the presence of a single hand. The book has been well received; its dissertation received the research prize of the Europäisches Romanik Zentrum, and the Trier library exhibited the Gregory leaf in the spring of 2026 to mark its publication.
This reassessment does not diminish the works themselves. Rather, it shifts the question from who painted them to how they were made, and it invites a reading of the technical evidence, once taken as proof of an individual, as the practice of a specialised workshop.
Conclusion
The Master of the Registrum Gregorii is a figure assembled by scholars rather than recorded by his contemporaries. No document names him and no signature survives, and his convenience name comes from a single detached leaf in Trier. The painter who emerges from the literature is one of the most admired artists of the Ottonian world, and one of the most hypothetical. Every statement about him rests on a chain of attributions, and it is the strength of the chain, not the certainty of any single link, that gives the construction its credibility.
The works grouped around him span roughly a quarter of a century. The Lorsch Sacramentary, made in Trier around 975–980, is usually placed at the beginning. The Registrum Gregorii followed between 983 and 993, and the Codex Egberti, the Sainte-Chapelle Gospels and the evangelist portraits added to the Strahov Gospels belong to the same decade. The Manchester Gospels, made for Otto III between 996 and 1002, stand at the far end. The order is a hypothesis. The Registrum is bounded by firm dates, but the Manchester book is attributed to the Master only possibly, and the Strahov portraits have been called early work without agreement on their place. The sequence from Lorsch to Manchester should therefore be read as a reasoned proposal rather than a documented biography.
What gives the group its coherence is above all a manner of treating space and the human body. In the Gregory leaf the pope sits within successive planes of curtain, column and roof, and the viewer’s eye moves through the image layer by layer. In the Chantilly leaf depth is reconciled with a hierarchy of scale that makes the emperor larger than everything around him. The figures have weight and volume, the drapery falls in long, even curves, the modelling is soft and the colour luminous. The same calm recurs in the evangelists of Paris and Prague, and it is already present in the Crucifixion of the Lorsch Sacramentary. It is a classicising art, and its sources are plural. The Master drew on Late Antique forms, on Carolingian painting from Tours and from the court school of Charlemagne, and on at least one Byzantine composition, the Niketas Bible. He fused these into a language that corresponds to no single model.
The cycles of evangelists show how that language worked in practice. The Sainte-Chapelle portraits and the Strahov portraits share motifs, furniture and verses, and the Strahov Matthew opens with the same words as the Paris one. Yet the types are exchanged between the two books. Matthew is old in Paris and young in Prague, John is young in Paris and old in Prague, and Mark is a bishop in one book and an antique author in the other. The painter, or his workshop, disposed of a repertory of figures and varied it from page to page. The Manchester incipits show the same principle at the level of the initial. Each Gospel opens with a monogram or a monumental letter on a purple panel, while the structure and the frame change from Matthew to John. The art is one of controlled variation within a shared system, not of repetition.
These images were also instruments of meaning. The Registrum diptych joins the inspired pope to the wise emperor across an opening, and its quotation from Sirach acquires its full sense only when the two leaves are seen together. The ruler medallions of the Sainte-Chapelle Matthew, if they are read as members of the Ottonian house, place a Gospel incipit within the politics of 984. The four medallions of the Manchester Matthew, each inscribed Otto imperator augustus, bind the sacred text to the person for whom the book was made. The verses that accompany the evangelists, the Eusebian notes in the margins and the Lamb of God at the heart of the John incipit show that theology and learning were as much part of the design as splendour. In Egbert’s Trier the art of the book served devotion and the representation of power together.
The technical evidence adds a further dimension. The Master alone among the painters of the Codex Egberti used azurite, worked his underdrawings with washes and painted his backgrounds before the figures. He applied gold leaf cut to shape and glued on after the painting was finished, a practice recorded again in the Registrum leaves and the Strahov Gospels. He appears also to have been a scribe, since Hartmut Hoffmann recognised his hand in the rustic capitals of the Registrum and compared the inscription in the Luke portrait of Paris with his minuscule. These habits have suggested a training in the goldsmith’s craft, which would fit a city where metalwork and painting flourished side by side. The suggestion remains plausible but unproved, and the further attributions to charter, ivory and enamel belong to the speculative margin of the oeuvre.
The literature on the Master has itself passed through three phases. The first built the artist on stylistic grounds and placed him at the summit of Ottonian painting. The second refined the picture through palaeography, political history and technical study, and proposed a career with an early phase connected with Lorsch and Trier, a possible interlude at Reichenau, a mature phase in Trier and a late phase extending beyond 996. The third phase, represented by Ursula Prinz’s monograph of 2026, argues that the Gregory Master is above all a convenience name. In her view the model of a single master owes much to a lingering cult of artistic genius, and the evidence is better explained by a group of artists working closely together from shared models. Fixed schemes for drapery and flesh tones, and recurrent motifs such as the circular fold on the belly, then no longer prove the presence of one hand.
This reassessment does not diminish the works. It changes the question that they ask. Whether the Registrum leaves, the Paris and Prague evangelists and the Manchester incipits are the work of one painter, of a master directing collaborators, or of a specialised Trier workshop, their quality and coherence are not in doubt. Their influence is visible in the later history of the books themselves. The Sainte-Chapelle Gospels served as a model at Echternach, and the Manchester Gospels shaped the illumination of Cologne soon after they were made. Through such books the classicising art of Egbert’s Trier passed into the eleventh century. The name of the Master may remain a convenience, but the art it designates, and the workshop that made it, stand among the most accomplished achievements of Ottonian painting.
