“And here we may as well mention the works of Hermes Trismegistus. Who, or how many have had the opportunity to read them as they were in the Egyptian sanctuaries? In his Egyptian Mysteries, Iamblichus attributes to Hermes 1,100 books, and Seleucus reckons no less than 20,000 of his works before the period of Menes.
Eusebius saw but forty-two of these “in his time”, he says, and the last of the six books on medicine treated on that art as practiced in the darkest ages; and Diodorus says that it was the oldest of the legislators Mnevis, the third successor of Menes, who received them from Hermes. Of such manuscripts as have descended to us, most are but Latin retranslations of Greek translations, made principally by the Neo-platonists from the original books preserved by some adepts.
