The collection includes Iamblichus' famous On the mysteries of the Egyptians, along with numerous other neo platonic and hermetic works, many dealing with demonology, magic, and other occult matters. Authors include Proclus, Porphyry, Michael Psellus, Pythagoras, Xenocrates, Hermes; plus commentary contributions by Ficino. The volume includes, among other works, the Asclepius, and the first fourteen treatises of the Corpus Hermeticum (under the collective title Poemander); as well as De Operatione Daemonum, a discourse on the nature and classification of demons, by Michael Psellus, a Byzantine monk. The myth of Hermes Trismegistus is fully outlined in this book, translated by Ficino, from a manuscript purchased by Cosimo de Medici. The manuscript, printed in Macedonia, was the beginning of the Hermetic tradition in the West. Hermes, the teacher of wisdom to the Egyptians, was such a power, he changed the direction of Western civilization in terms of spirituality and religious philosophy, ushering in modern occultism. Hermes' legend transformed science, mathematics, religion, and the entirety of Western culture. 
 
Without any doubt, this is the foundational book of Western Esotericism, Hermeticism and Occultism.  Gathered in these pages are the summation of ancient Pagan esoteric wisdom selected and translated by the leading Renaissance mystical philosopher, Marsilio Ficino - see list of titles below - printed by the most celebrated printer of the period, an absolute tour de force.  Printed within the first 100 of printing itself, this very rare volume represents the dawn of how print would introduce a radically new spirituality into the west and would be the crown of an occult book collection.
