The Hermetica, or Corpus Hermeticum, is the codification of many tracts and dialogues that are believed to be the beliefs, religion, and philosophy of ancient Egypt.

A prime product of the Hellenistic culture of Alexandra, Egypt, the Hermetica was the foundation of a Graeco-Egyptian religion. It has had a profound influence on philosophy, theology, and occultism. As a "secret document", the Hermetica has influenced many great European thinkers across the centuries and is credited as being one of the prime catalysts of the Renaissance.
