Prison Meditations on Psalms 51 and 31 (Infelix ego and Tristitia obsedit me)
Expositio in Psalmum Miserere mei Deus; Tristitia obsedit me (incomplete: Expositio in Psalmum In Te Domine Speravi)
In te, Domine, speravi, non confundar in aeternum.
Our renderingIn you, Lord, I have placed my hope; may I never be put to shame.
What it is
Two meditative expositions of Psalms 51 and 31 (Vulgate 50 and 30) written by Savonarola in a Florentine prison while awaiting execution. The Psalm 51 meditation ('Infelix ego') is complete; the Psalm 31 meditation ('Tristitia obsedit me') is unfinished, as Savonarola was executed before completing it—the latter opens a personified dialogue between the writer, Sadness, and Hope. Within two years the Psalm 51 text went through eight Latin editions; more than seventy-eight combined editions of both texts appeared in Latin and vernaculars by 1600. They circulated throughout Florence precisely during the formation of the future Medici popes but were not commissioned by the Medici.
Why it still matters
These meditations offer a direct model for praying through the Penitential Psalms as honest self-examination and trust in divine mercy; praying the two texts consecutively traces a movement from desolation into hope.

Girolamo Savonarola, Expositio in Psalmum Miserere mei Deus (Infelix ego)
Expositio ac meditatio in Psalmum Miserere mei Deus / Infelix ego
Written by Savonarola in May 1498 while imprisoned in Florence awaiting execution, this meditation on Psalm 51 (Miserere mei Deus) was smuggled from his cell and published in Ferrara the same year, reaching numerous Italian editions before 1500. It proceeds verse by verse through the psalm, weaving personal confession with theological reflection on divine mercy and human unworthiness. Savonarola had been the dominant preacher in Florence throughout the later Medici period, and this text became the most widely circulated spiritual writing in post-Medici Florence, carried by the Piagnoni lay reform movement as their central devotional text. Its composition under sentence of death gives it an intensity matched by few comparable documents of the Italian Renaissance.
Triumph of the Cross (Triumphus Crucis)
Triumphus Crucis seu De Veritate Fidei
Savonarola's major theological apologetic, arguing that the Christian faith rests on reason, history, Scripture, and the testimony of the Church Fathers, with a sustained central meditation on the Cross as the triumph of divine love over sin and death. First printed in Florence by Bartolommeo di Libri c. 1497 under the title Triumphus Crucis seu De Veritate Fidei, it was composed while Savonarola led San Marco—the convent patronised and rebuilt by the Medici—and it circulated throughout Florence during Leo X's youth and Clement VII's formation. It was not commissioned by the Medici; Savonarola remained their declared political adversary throughout its composition.
Theologia Platonica de Immortalitate Animae (Platonic Theology)
Ficino's eighteen-book systematic exposition of Neoplatonic philosophy in service of Christian theology, dedicated to Lorenzo de' Medici in its preface; the manuscript was circulated from the 1470s, and the editio princeps was printed in Florence by Antonio di Bartolommeo Miscomini on 7 November 1482. Its central argument — that the human soul is the copula mundi, the pivot of the cosmos, drawn upward through love and contemplation from body through mind to God — provided the intellectual and theological backbone of Medici court culture. While not a prayer manual, it was the philosophical foundation from which Ficino drew his personal letters of spiritual direction to Cosimo and Lorenzo and shaped the devotional atmosphere of the Careggi Academy.
