What it is
A personal prayer book commissioned by Ercole I d'Este, Duke of Ferrara, and produced in his court scriptorium around 1482, this manuscript contains prayers and meditations drawn from the Pseudo-Augustinian Soliloquia animae ad Deum and related devotional compilations attributed to Augustine of Hippo. Written by court scribe Andrea delle Vieze and illuminated with sixty-eight gold-embellished miniatures and over 130 gilded initials by Tommaso da Modena, this small parchment codex (18 × 11.8 cm) was explicitly designed for intimate, daily personal use. It is one of four sumptuous devotional books ordered by Ercole I for his own private prayer life, attesting to an intense and consistent Augustinian spirituality at the heart of Este court piety. The manuscript is now at the Biblioteca Nazionale Marciana in Venice, having left Ferrara when the Este court relocated to Modena in 1598.
Why it still matters
The Augustinian meditations collected here — centred on self-knowledge, longing for God, and penitent love — are among the most prayed texts in Western Christianity and remain a living resource for personal contemplative prayer today; the Soliloquia are widely available and require no specialist knowledge to use.

Prison Meditations on Psalms 51 and 31
Savonarola composed these meditations on Psalm 51 (Miserere, known as 'Infelix ego') and Psalm 31 (In te, Domine, speravi) in Latin while imprisoned in the Palazzo della Signoria in 1498 awaiting trial and execution, his right hand temporarily spared from further torture so he could sign his confession. Approximately 15 Italian editions appeared by 1500, making them among the most rapidly disseminated devotional texts of the early print era and ensuring pan-European reach within a decade. Savonarola had preached at San Marco — the monastery Cosimo de' Medici built and patronized — from 1482 and was the friar summoned to Lorenzo de' Medici's deathbed in 1492, giving these works an indirect but real connection to the Medici devotional world. The Miserere meditation (Infelix ego) became one of the most reprinted Latin spiritual texts of the sixteenth century.
Infelix ego (Meditation on Psalm 51 / Miserere)
Infelix ego, omnium auxilio destitutus
A profound Latin meditation on Psalm 51 (Miserere) composed in his Florentine prison cell by the Dominican friar Savonarola shortly before his execution on 23 May 1498. Despite being the Medici's principal political opponent, his text circulated in fifteen Italian editions by 1500 in the very city where Giovanni de' Medici (future Leo X) and Giulio de' Medici (future Clement VII) were formed; Martin Luther endorsed it in 1523. Josquin des Prez, Cipriano de Rore, and William Byrd set versions to polyphony, securing its place across a century of European devotional music. Its connection to Medici piety is environmental rather than by commission or documented use.
Savonarola's De simplicitate Christianae vitae
De simplicitate Christianae vitae (On the Simplicity of the Christian Life)
Written in 1495 and first printed in Florence by October 1496, this five-book Latin treatise argues that authentic Christian life requires stripping away worldly wealth, ambition, and complexity to seek God through prayer, Scripture, and the sacraments. The Este connection rests on the documented personal and spiritual correspondence between Savonarola and Ercole I d'Este (approximately twelve surviving letters from the 1490s) and on Ercole's well-attested admiration for Savonarola, which prompted religious reforms in Ferrara during the same period. Girolamo Benivieni's vernacular Italian translation, circulated in Florence in late 1496, extended the text's reach well beyond the court. The claim of a manuscript copy dedicated specifically to Ercole in January 1496 is unconfirmed in available scholarly sources and should be treated as traditional attribution only.
