Genealogy of Perennial Wisdom — Part 3: Zoroaster, the Neoplatonists and the Lost Dreams of the Renaissance

This part of the genealogy begins with a major historical rupture: the fall of Constantinople in 1453 and the movement of Greek scholars and manuscripts into Italy. Byzantine intellectual culture retained more direct access to Greek texts and language, whereas the Latin West often knew major works through translation. The movement of books and teachers toward Florence is presented as one important condition of the Renaissance revival of Plato and Neoplatonism. Within this setting, Cosimo de’ Medici and the Florentine circle launched a new effort to recover ancient wisdom.

Georgios Gemistos Plethon is central to the story. He restored Plato’s prestige against the dominant medieval Aristotelian frame and believed in a primordial wisdom connecting Zoroaster with Plato. The Chaldean Oracles, then strongly associated with the name of Zoroaster, were treated by Plethon and many Renaissance readers as evidence of that lineage. His influence in Italy was substantial enough that the Florentine Platonic revival is difficult to narrate without him.

Marsilio Ficino developed the project as a prisca theologia, an “ancient theology” according to which fragments of primordial truth existed among ancient sages before Christianity and ultimately converged with Christian revelation. Zoroaster posed a difficulty. If the source of this wisdom was placed in an Iranian prophet and a tradition outside biblical genealogy, the relationship to Moses and Christian revelation became more complicated. The European association of the Magi with magic and alchemy also made Zoroastrian primacy theologically uncomfortable for a committed Christian intellectual.

The seminar follows a gradual shift in Ficino’s later writings and prefaces from Zoroaster toward Hermes Trismegistus. Hermes offered an ancestry that could be made more compatible with Christian theological history and later became central to accounts of Western esotericism. In the twentieth century, especially through Frances Yates’s work on Giordano Bruno and Hermeticism, the Renaissance was increasingly narrated as “Hermetic,” while Zoroaster’s place in the popular genealogy faded.

The seminar treats this shift as more than neutral correction: it illustrates how intellectual ancestries are rewritten according to theological and cultural needs. At the same time, historical Zoroaster must be distinguished from works such as the Chaldean Oracles, whose attribution to Zoroaster is contested and in modern scholarship is generally treated as pseudonymous or symbolic. The deeper value of the seminar lies in showing how Renaissance thinkers imagined the past: as a chain of ancient wisdom in which philosophy, religion, magic, science, and transformation of the soul had not yet become separate domains.
