Hermeticism

"Hermeticism, also called Hermetism, is a religious, philosophical, and esoteric tradition based primarily upon writings attributed to Hermes Trismegistus ('thrice-greatest Hermes'). These writings have greatly influenced the Western esoteric tradition and were considered to be of great importance during both the Renaissance and the Reformation. The tradition traces its origin to a prisca theologia, a doctrine that affirms the existence of a single, true theology that is present in all religions and that was given by God to man in antiquity."
