What it is
Created around 1469 for the marriage of Ferrarese diplomat Andrea Gualengo to Orsina d'Este, a niece of the ruling marquis, this book of hours is among the most important Italian manuscripts at the J. Paul Getty Museum (Ms. Ludwig IX 13). Painted chiefly by Taddeo Crivelli with contributions from Guglielmo Giraldi, both leading court illuminators of Ferrara, it contains the Hours of the Virgin, Penitential Psalms, Hours of the Holy Cross, Office of the Dead, and suffrages — short votive prayers to individual saints. The full-page miniatures blend Ferrarese Renaissance naturalism with classical architectural framing, making this one of the finest secular-devotional commissions of the Quattrocento. Its creation at the intersection of diplomacy and dynastic alliance gives it an unusual social depth for a personal prayer book.
Why it still matters
The suffrages and Hours of the Virgin it contains are among the most intimate and widely practised devotional prayers of the medieval tradition; Christians today can use these same texts to structure morning and evening prayer or to pray before particular saints.

Llangattock Breviary (Breviary of Leonello d'Este)
Breviarium ad usum Ferrariensem (Breviary of Leonello d'Este)
Commissioned by Leonello d'Este, Marquis of Ferrara (r. 1441–1450), for his private chapel, this sumptuous breviary contains the Calendar, Temporale, Psalter, Sanctorale, Common of Saints, and Auxiliary Texts, written in Gothic textualis rotunda on parchment. Illuminated by four leading Ferrarese artists, it served as the principal liturgical book of the Este chapel under Leonello and represents the fullest flowering of the first generation of Ferrarese court illumination. Broken up and sold as individual leaves at Christie's in December 1958, its folios are now tracked by the Broken Books digital project and survive in Harvard, the Bibliothèque nationale de France, the Museo Schifanoia in Ferrara, and other collections. Its dispersal makes it one of the most prominent cautionary cases in the history of manuscript disbound for the art market.
Hours / Officium Beatae Mariae Virginis of Anna Sforza and Cardinal Ippolito d'Este
Officium Beatae Mariae Virginis (Hours of Anna Sforza / Cardinal Ippolito d'Este)
Produced in Milan around 1491–1500 by the Sforza court illuminator Francesco Binasco, this luxury Book of Hours links the Sforza and Este dynasties through the marriage of Anna Sforza to Alfonso I d'Este in January 1491. Scholarly debate continues over whether it was commissioned by Cardinal Ippolito d'Este — whose cardinal's hat appears in the manuscript — or prepared as a wedding gift for Anna Sforza; the cardinal's hat strongly suggests Ippolito as the primary patron. It contains a Roman-rite calendar, privately ordered prayers of devotion, twelve full-page miniatures of the Virgin and female saints, and 146 historiated initials. Now preserved at the Biblioteca Estense Universitaria in Modena (MS Lat. 74 / alfa Q.9.31), it is a rare documented case of a Book of Hours that bridges the devotional cultures of two of northern Italy's most powerful courts.
Borso d'Este Bible (Bibbia di Borso d'Este)
Bibbia di Borso d'Este
Commissioned by Borso d'Este, first Duke of Ferrara (r. 1450–1471), between 1455 and 1461, this two-volume illuminated Bible is regarded as one of the supreme masterpieces of Renaissance manuscript illumination, with 1,202 decorated pages produced by a workshop led by Taddeo Crivelli and Franco dei Russi. Its primary function was dynastic and representational: it was designed as a public demonstration of Este magnificence and legitimacy rather than a personal devotional text, and it was displayed in the chapel as a symbol of ducal piety rather than carried privately for daily prayer. The complete Latin Vulgate text it contains — including all 150 Psalms — meant it also served as a liturgical and devotional reference, but scholarly consensus is that prestige rather than prayer was its animating purpose. It is preserved at the Biblioteca Estense Universitaria in Modena (MS Lat. 422–423) and was exhibited in Rome in 2024–2025.
