The objective of the article is double. On the one hand, it is aimed at examining the reworking of the Prisca Theologia, by Marsilio Ficino, Florentine neoplatonic of the XV century. That is: a wisdom whose origins date back to the Egypt of the Pharaohs and the Persia of Zoroaster. A millenary tradition that contained within it the doctrines of a true pia philosophia. On the other hand, to analyze the reception of hermeticism in the thought of Ficino and his (...) attempt to generate a concord between christianity and paganism. We consider also that in this attempt, Ficino elaborates along his works three images of Hermes Trismegisto which are condensed in his main purpose, to prove the manifest harmony between the doctrines of the ancient pagan theologians and Christian Theology.
