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.
Miserere mei Deus secundum magnam misericordiam tuam, et secundum multitudinem miserationum tuarum dele iniquitatem meam.
Our renderingHave mercy on me, O God, according to your great mercy, and according to the multitude of your tender mercies, blot out my iniquity.
What it is
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.
Why it still matters
The Miserere meditation can be read directly alongside Psalm 51 as a personal examination of conscience and act of contrition; it remains among the most powerful Christian treatments of repentance and grace in the Latin tradition.

The Imitation of Christ
De Imitatione Christi
Written by Thomas à Kempis in the Netherlands in the circle of the Brethren of the Common Life — the same Devotio Moderna movement that directly shaped Margaret of York's documented devotional practice and the piety of Isabella of Portugal at the Burgundian court — the Imitation became the most copied vernacular religious text in 15th-century Europe, circulating in thousands of manuscripts and hundreds of early printed editions. Its four books move from the vanity of worldly learning through conformity to Christ, inward consolation, and finally the sacrament of the Eucharist, forming a complete program of interior conversion. No specific ducal inventory copy has been identified linking this text to Valois-Burgundy by name, but its presence in court circles of this era and region is established through movement history rather than document. It remains the second most widely read Christian book after the Bible.
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.
Sant'Agostino Estense (Orationes of St. Augustine for Ercole I d'Este)
Orationes ex Meditationibus et ex Soliloquiis Divi Patris Augustini Episcopi Hipponensis
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.
