This elegant, illuminated Carthusian Breviary comes from the library of the important Charterhouse of Valmanera, or Asti, in Northern Italy. The cycle of saints’ portraits may have been executed in the workshop of the Master of the Vitae Imperatorum, one of the most important illuminators in Northern Italy in the first half of the fifteenth century. The richness of this volume, surviving in fine condition, stands in marked contrast to its use, and possible origin, in an austere Charterhouse: for a Carthusian monk, living in strict solitude, a book like this one was his only companion.
1.The style of decoration within this manuscript dates to the second quarter of the fifteenth century, c. 1430-1450, and indicates that the volume was most likely produced, and was certainly illuminated, in Lombardy, perhaps in Milan (see Illustration, below). This dating is corroborated by the contents of the calendar, which includes observances instituted in the Order as late as 1420. A date before 1462, when the feast of Catherine of Siena (May 6), was added to the Carthusian liturgy, is likely (this important feast is not included in the calendar); certainly copied before 1470 when the feast of the Sanctification of the Blessed Virgin, celebrated on 8 December, was renamed the feast of the Conception of the Blessed Virgin.
This manuscript was definitely made for Carthusian use. The specification “candele” in the calendar refers to the Carthusian practice of lighting two candles for Mass, Lauds, and Vespers for particularly important feast days. The prominence in the calendar, litany, and Sanctorale of Saint Hugh of Grenoble, who aided Saint Bruno in founding the Carthusian Order, and of the Carthusian Saint Hugh of Lincoln also point to Carthusian use, as do the responsories in the Office of the Dead and, of course, the inclusion of Carthusian constitutions regarding liturgy. One of the historiated initials included within the volume features a Carthusian saint, most probably Hugh of Lincoln (f. 50).
The book belonged very early to the Charterhouse of Asti (also known as the Charterhouse of Valmanera), a Carthusian house in Asti, in Northwestern Italy, as indicated by an inscription in the lower margin of f. 4: “ccxliij. B. Monasterij cartusie Ast.” Founded in the first half of the twelfth century as a Vallombrosan monastery, the house passed to the Carthusian Order in the late fourteenth century, when important families in Asti called for the Carthusians to replace what had become a decadent community. This change was supported by the popes in both Avignon (in a papal bull of 1387) and Rome, and the new Carthusian foundation, dedicated to Saints James and Philip, was endowed with extensive properties. The only known catalogue of its library, now Vatican, Vatican Library, Cod. Vat. lat. 11276, lists 354 works, including works in print. The house was suppressed in 1801 when it was confiscated by the Napoleonic government, and many of its treasures were transferred or lost. By their own request, the monks were able to retain some of the library’s contents as personal possessions, but most of them appear to have been appropriated for the foundation of a public library (see Chiarle, 2011, pp. 253-254).
The book may also have been copied by a member of this house. The hand in which this inscription was written may belong to the scribe who copied the manuscript. The Carthusian Order placed a special emphasis on scribal work as an appropriate form of manual labor and as a standard practice for monks and nuns in the solitude of their own cells. Carthusian statutes offer a justification for this labor: “ut quia ore non possumus dei verbum manibus predicemus” (so that because we are not able to preach the word of God with our mouths, we may do so with our hands). This manuscript could well have been produced by a Carthusian scribe under such circumstances. The scribe shows an investment in the book’s accuracy and utility, having taken care to correct and expand the text and, in section III, cross-reference other folios in the manuscript. Carthusian statutes stressed the importance of establishing correct texts – chiefly the responsibility of the Grande Chartreuse – and of emending texts against these correct exemplars (Rouse and Rouse, 1991).

II. ff. 12-82v:
ff. 12-64, Gallican Psalter, beginning imperfectly, “// malignus neque permanebunt iniusti ante oculos tuos ...”; f. 12, [Psalm 6] Psalmus dauid, incipit, “Domine ne in furore tuo arguas me ... [f. 64, Psalm 150] ... omnis spiritus laudet dominum”;

Instructions for the observance of liturgical feasts specific to the Carthusians.
f. 19v, King David, crowned and bearded, shown half-length in a red robe with a blue and green mantle, holding a pale orb and golden scepter (Psalm 26: “Dominus illuminatio mea ...”);
f. 22, King David, crowned and bearded, shown half-length in a red robe, playing a harp (Psalm 32: “Exultate iusti in domino ...”; Feria secunda);
f. 28, young man, crowned, shown half-length in a red garment holding a golden rod (Psalm 52: “Dixit insipiens in corde suo ...”);
f. 30v, Saint Jerome as a penitent, shown half-length baring his chest under a brown robe and holding a stone in one hand (Psalm 59: “Deus repulisti nos ...”; Feria iiij);
f. 32, young man with a halo (possibly Saint George?), shown half-length in a red garment, holding a sword and a lance (Psalm 65: “Iubilate deo omnis terra ...”);
f. 33v, King David (?), bearded and wearing a hat, shown half-length in a red robe with his arms crossed over his chest (Psalm 68: “Saluum me fac deus ...”);
f. 36v, Saint John the Baptist, shown half-length and in partial profile in an animal skin, point toward a scroll (Psalm 73: “Ut quid deus repulisti in finem ...”; Feria quinta);
f. 40v, balding, grey-bearded man with a halo, shown half-length in a green robe with a red mantle, his hands clasped in prayer (Psalm 79: “Qui regis ysrael intende ...”);
f. 42v, tonsured Franciscan monk with a halo (Saint Francis or Saint Anthony of Padua?), shown half-length in a brown habit, holding a golden book and a golden cross (Psalm 85: “Incline domine aurem tuam ...”);
f. 46v, Saint Nicholas, shown half-length in profile wearing a mitre and a red cope decorated with gold over a white robe, holding three golden balls and a golden crosier (Psalm 95: “Cantate domino canticum nouum ...”; Feria vj);
f. 50, Saint Hugh of Lincoln (?), shown half-length with a bishop’s mitre and a red cope over a white scapular and robe, arms raised, with one hand open and a crosier the other (Psalm 105: “Confitemini domino ...”);
f. 53v, Saint Bernard of Clairvaux, shown half-length in white habit, holding a red book and a golden crosier (Psalm 118: “Beati immaculati in uia ...”; Ad primam de dominica);
f. 64, balding, grey-bearded man with halo (St. Paul?), shown half-length in a dark red robe with a red mantle, holding a red book in one hand and a sword in the other (opening of the canticles);
f. 74v, Saint Ambrose, shown half-length with a bishop’s mitre and a red chasuble decorated with gold, holding a scourge in one hand and an open book and golden crosier in the other (opening of the hymns).
All but three of these fourteen initials were painted in green or mauve, decorated with delicate white highlighting and dark shading, with blue backgrounds decorated in liquid gold in swirling patterns or radiating lines and on burnished gold grounds outlined in black. The first initial (f. 19v) follows the same pattern but with the initial apparently painted in blue (somewhat obscured now by oxidation?) with a black ground decorated with radiating lines painted in liquid gold. In the other two cases (ff. 32 and 42v), both the initial ‘I’, the initial itself has been executed in burnished gold on a blue ground decorated with radiating lines painted in liquid gold. All of these initials are adorned with gently curving acanthus extensions of blue, green, red, and mauve, highlighted and shaded with delicate pen decoration. Burnished gold bezants appear in the margins alongside these foliate extensions.
With the exception of Saint Nicholas, shown in strict profile, and Saint John the Baptist, shown with his face in profile, these historiated initials present bust-portraits whose subjects face mostly forward, but always slightly toward the text. Their features are similarly delineated with slight dark strokes setting off their brows, eyes, lips, and noses. The haloes of the saints have been executed in burnished gold, outlined in black. Much care has been lavished on highlighting the drapery and folds of the figures’ clothing.
Aside from the three initials depicting King David, hardly surprising given that nearly all of these initials fall within the volume’s Psalter, this cycle of historiated initials is notable in its subject matter, focused as it is on important monastic saints and doctors of the Church. Historiated initials with bust-portraits of saints or teachers are typical in Lombard and Milanese book illumination of the fifteenth century. The portraits of kings, teachers, and prophets in the cuttings of London, British Library, Add. MS 18196, ff. 71-77, executed in the circle of the Master of the Arcimboldi Missal, produced at the end of the fifteenth century, bear witness to the longevity of a number of patterns that are rooted deeply in Milanese illumination of the fifteenth century.
The style of the initials on square burnished golden grounds, with their extending and curling acanthus leaves, resembles that in a Book of Hours produced c. 1430-1440, Les Enluminures, BOH 101, and a Breviary produced c. 1430, Baltimore, Walters Art Museum MS W. 332 (Online Resources), both of which contain similar portraits, almost certainly produced around the same time as those in the present manuscript. The Hours of the Virgin of the former and the Sanctorale of the latter include similar programs of illuminated initials with saints’ half-length portraits. The form of the initials, the blue backgrounds with delicate radiating lines drawn in liquid gold (see in particular ff. 37v, 210v, 222v, and 396 in the Baltimore Breviary), and the foliate extensions are similar enough that it is possible that the same workshop executed the secondary decoration in all of these manuscripts. The figures themselves, though similar in their haloes, crosiers, and draperies, differ somewhat from those in the other manuscripts, with softer faces (more akin to those of the Baltimore Breviary than the Book of Hours, but with proportionally smaller heads and darker modeling).
The illumination in the Baltimore Breviary has been attributed to the Master of the Vitae Imperatorum, and that of the Book of Hours to his workshop (on this illuminator, see Alexander, 2002, Melograni, 1990 and 1996; Palladino, 2003). Active from 1430 to 1453 in Milan, the Master of the Vitae Imperatorum counts among the most significant Lombard artists of his time. He is named after a copy of Suetonius, now Paris, BnF, MS it. 131, dated December 1431. The master was trained by Tomasino de Vimercate and worked for Filippo Maria Visconti, duke of Milan, and his court. Among his known masterpieces are the Bible of Mary of Savoy, Chambéry, Bibliothèque municipale (in collaboration with Belbello da Pavia) and the illustrations of Dante’s Inferno for Filippo Visconti, now Paris, BnF, MS it. 2017.
The opulence of this Breviary stands in marked contrast to the austere conditions in which it must have been used. Furthermore, the arrangement of its contents is highly uncommon. Breviaries contain the complete text of the Divine Office, encompassing a program of readings, prayers, hymns, canticles, and Psalms arranged according to the canonical hours of the Divine Office (Matins, Lauds, Prime, Terce, Sext, None, Vespers, and Compline). This is a monastic Breviary, which includes twelve lessons at Matins for major feasts. Unlike many monastic Breviaries, which include the texts for only part of the year, this manuscript includes the entire year in one rather lengthy, but not very large volume. Even more strange is this book’s organization: though it contains the texts that would have been read or chanted in the Divine Office, it does not present them, as most do, in anything approximating the order in which they would have been read, organized chiefly according to the hours of the Office. Instead, the separate presentation of capitula, collects, antiphons and responses, and longer readings would have necessitated constant navigation of this substantial volume.
A careful system of internal references, using the folio numbers that are original to the manuscript, would have facilitated the use of this lengthy Breviary and aided a reader in navigating this Breviary’s segmented organization. Still, this book’s arrangement calls into question whether it would have been used on a daily basis by a monk participating in the Office. It is possible, instead, that this fine and notably well-preserved volume was intended chiefly to preserve the correct text of the Carthusian Office, to be consulted as an exemplar for the copying and correction of more workaday Breviaries (recalling the importance of correct texts to the Carthusians). In this light, it is worth noting that this Breviary’s odd arrangement was not unheard of in Carthusian Breviaries. Grenoble, Bibliothèque muncipale, MSS 73 and 74, datable to the fourteenth- and a fifteenth-centuries, respectively, contain a similarly extensive range of contents organized quite similarly (see Leroquais, 1934, II, pp.115-117) and may have been put to a similar use.
The Carthusian Order, founded by St. Bruno of Cologne around 1084 and celebrated for the purity and austerity of its version of the religious life, is characterized by a unique combination of the eremetical and cenobitic life. Each Carthusian monk spends most of his life living as a hermit in his own cell, but at the same time lives under the rule and discipline of a community and participates in the communal liturgy of the monastery. The success of the Carthusians at creating a balanced life and maintaining this life through their statutes and the guidance of the Prior of the Grande Chartreuse and the Order’s General Chapter allows the Order to make the famous claim, “numquam reformata, quia numquam deformata” (never reformed because never deformed).
Carthusians embrace the strictest separation from the world, characterized by total dedication to contemplation through silence, prayer, penance, and almost continuous occupancy of a solitary cell. According to the Carthusian rite, the only offices sung collectively were Matins (and sometimes Lauds) and Vespers. The remaining Hours were recited (or sung?) in the privacy and solitude of each monk’s cell. Thus, the liturgical day of a Carthusian monk in the Middle Ages centered around the recitation of the Divine Office in his cell in between periods of work, study, and personal prayer, and attendance of the long night office of Matins and the evening office of Vespers in the church.
