Hermeticism or Hermetism is a philosophical system based on the teachings of the ancient Egyptian God known as Thoth. In Egyptian mythology, the god Thoth was often depicted as having many forms, but the most well-known was that of a humanoid with the head of an Ibis bird or sometimes depicted with the head of a baboon primate since animals were sacred to him. Other times he is seen wearing the Atef crown or a double crown.
