A sect of Gnostic heretics, followers of Basilds, an Alexandrian Gnostic, who taught that from the unborn Father Mind was begotten; from Mind proceeded The Word; from the Word or Logos proceeded Understanding; from Understanding Wisdom and Power; from Wisdom and Power Excellencies, Princes, and Angels, the agents which created heaven. Next to these high mightinesses come 365 celestial beings, the chief of whom is Abraxas (q.v.), and each of whom has his special heaven. What we call Christ is what the Basilidians term The first-begotten Mind.
