A primarily religious amalgam of Greek philosophy with Egyptian and other Near Eastern elements, Hermetism takes its name from Hermes Trismegistus, ‘thrice greatest Hermes’, alias the Egyptian god Thoth. Numerous texts on philosophical theology and various occult sciences, ascribed to or associated with this primeval figure, were produced in Greek by Egyptians between roughly ad 100 and 300, and are a major document of late pagan piety. Reintroduced into Western Europe during the Renaissance, they provided considerable inspiration to philosophers, scientists and magicians of the fifteenth and sixteenth centuries.
