Epistolae (Letters of Marsilio Ficino)
quasi ad contemplationi sacrarium rite celebrandum me confero.
Our renderingI betake myself, as it were, to celebrate duly at a shrine of contemplation.
What it is
Twelve books of letters addressed to Cosimo de' Medici, Lorenzo de' Medici, Cristoforo Landino, Poliziano, and the wider Platonic Academy circle, begun in the 1460s, circulated in manuscript widely from the 1470s, and printed in Venice in 1495. In a letter of September 1462 to Cosimo, Ficino describes his work at Careggi as worship 'at a kind of shrine of contemplation,' revealing the devotional character of the entire philosophical enterprise. The letters function as living instruments of moral and spiritual formation, repeatedly urging rulers and scholars to integrate contemplation with the demands of active public life. They constitute the most immediate surviving record of the Ficino-Medici relationship as a real spiritual direction.
Why it still matters
Ficino's letters offer a practical model of integrated spiritual direction for people in public and professional life — making them directly useful for Christian leaders or anyone seeking to weave contemplation into active responsibility.

Letters of Marsilio Ficino (Epistolae)
Epistolae Marsili Ficini Florentini
Ficino's twelve books of spiritual correspondence, addressed to members of the Medici household and the Platonic Academy, are masterpieces of devotional spiritual direction in a Neoplatonic Christian register. Lorenzo de' Medici received numerous letters on the soul, love, and the ascent to God, and Ficino read Plato's dialogues to the dying Cosimo de' Medici in 1464, demonstrating the texts' integration into Medici piety at the most solemn moments of life. The Venetian first printing of 1495 reflects the fact that Savonarola's faction then dominated Florence and was hostile to Ficino's Medici patrons. A modern selection is accessible in English as Meditations on the Soul (Shepheard-Walwyn).
Antoninus of Florence, Confessionale (Defecerunt / Curam illius habe)
Confessionale volgare et Curam illius habe
Archbishop Antoninus Pierozzi OP (1389–1459), the Dominican prior of San Marco whose rebuilding Cosimo de' Medici funded, wrote both a lay Confessionale and the companion Curam illius habe (also known as Medicina de la anima) for use in personal confession and spiritual direction. He served as confessor and spiritual director to the Medici family, and Cosimo maintained a private cell at the monastery Antoninus governed; Antoninus also wrote the Opera a ben vivere, a guide to virtuous living composed specifically for women of the Medici household. These works represent the most direct pastoral link between the Medici family and Dominican moral theology, organized around the Ten Commandments and the seven deadly sins.
Marsilio Ficino, Epistolae (Letters)
Epistolae Marsilii Ficini Florentini
Ficino's twelve published books of letters, many addressed directly to Lorenzo de' Medici and members of the Medici intellectual circle, blend Platonic philosophical instruction with intimate spiritual counsel, forming a unique corpus of Christian humanist correspondence. Devotional letters addressed to the Camaldolese order treat contemplative ascent, divine love, and the soul's orientation toward God with unusual warmth and precision. As the household philosopher and tutor of the Medici circle, Ficino used these letters as an ongoing instrument of spiritual formation, and they circulated in manuscript before their 1495 printing.
