A gem engraved with the word Abrasax or Abraxas.
A theonym of unclear signification, commonly invoked as a magic word on amulets, talismans, and papyri in the Mediterranean basin from the 2nd century B.C. until the 13th century, and viewed in Gnosticism as one of the Archons who follows Sabaoth when he leaves the ranks of the Demiurge to become an aeon alongside Sophia.
