Abraxas

Abrasax (Gk. ΑΒΡΑΣΑΞ, which is far more common in the sources than the variant form Abraxas, ΑΒΡΑΞΑΣ) was a word of mystic meaning in the system of the Gnostic Basilides, being there applied to the “Great Archon” (Gk., megas archōn), the princeps of the 365 spheres (Gk., ouranoi). In Gnostic cosmology, the 7 letters spelling its name represent each of the 7 classic planets—Sun, Moon, Mercury, Venus, Mars, Jupiter, and Saturn.
