In Gnostic and late antique magical tradition, a potent name often inscribed on engraved gems and amulets. The name was associated with a composite, lion-headed or cock-headed figure and invoked as a symbol of cosmic power and protection.

From Late Greek Abrasax/Abraxas (Ἀβραξάς), a name occurring in Gnostic contexts (notably Basilidian) and widely disseminated on so-called "magical gems." Antiquarians noted that its Greek letters can be read numerically as 365, binding the name to the circuit of days. The deeper origin remains obscure, though its afterlife is clear: a word made talisman, carried forward by syncretic religion and later revived in modern occult and literary imagination.
