Hermes Trismegistus is considered the founder of science, religion, mathematics, geometry, alchemy, philosophy, medicine, and magic. He is a combination of the Egyptian Thoth – who was god of wisdom, learning and communications and the Greek Hermes – who was messenger of the gods. He is credited to have written somewhere between 20,000 to 36,525 works, of which 42 were kept in the great Library of Alexandria, which was destroyed multiple times.
