What it is
The Soliloquia animae ad Deum is a widely circulated anthology of pseudo-Augustinian devotional prayers — interior dialogues between the soul and God — that served as the direct textual source for the Sant'Agostino Estense, the personal illuminated prayer book commissioned by Ercole I d'Este in 1482. The full manuscript title, 'Orationes ex Meditationibus et ex Soliloquiis Divi Patris Augustini,' confirms the text used. Among the most frequently copied devotional compilations of the medieval West, the Soliloquia survives in at least eighty-four Latin manuscripts and draws extensively on the Confessions, the genuine Soliloquia of Augustine, and related Augustinian material, though it is not itself by Augustine. The Este court's commission of an illuminated version for Ercole's private use represents a documented and characteristic act of aristocratic lay devotion.
Why it still matters
Still read widely today within the Augustinian devotional tradition, the Soliloquia's intimate form of prayer as direct address to God is commended by the modern Church and available in modern editions; it is particularly suited to meditative evening prayer.

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.
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.
Savonarola's Infelix ego (Expositio in Psalmum Miserere)
Expositio ac meditatio in Psalmum Miserere, fratris Hieronymi de Ferraria
Written by the Dominican friar Girolamo Savonarola in his Florentine prison cell in May 1498, days before his execution, this meditation on Psalm 51 (Miserere mei Deus) became one of the most widely read devotional texts of the Renaissance, appearing in fifteen Italian editions by 1500. Its first printed edition was produced in Ferrara in 1498 by Laurentius de Rubeis, the city of Savonarola's birth and seat of the Este court, whose Duke Ercole I maintained approximately twelve documented letters of spiritual and political correspondence with Savonarola through the 1490s. Ercole I later commissioned Josquin des Prez to set the Infelix ego text musically around 1503–1504, resulting in Josquin's celebrated Miserere, most likely first performed for Holy Week 1504 at the Ferrarese court. The text belongs to the great tradition of penitential psalm commentary and stands as one of the most searing personal confessions in Renaissance devotional literature.
