The wor Abraxas (or Abrasax or Abracax) was engraved on certain antique stones, called on that account Abraxas stones, which were used as amulets or charms. The name is found in the Greek Magical Papyri, and the word may be related to the word abracadabra, although other explanations exist. The name is also found in Gnostic texts such as the Gospel of the Egyptians. Abraxas has also been variously claimed throughout the centuries to be an Egyptian god, a demon, and to represent God and Satan in one entity and the dual nature of its essence.
