(Abracax from Collin de Plancy's Dictionnaire Infernal)

The name of this demon is probably a corruption of Abrasax, also known as Abraxas, a god of the Gnostics who had the head of either a cock or a lion, the body of a man, and serpents for legs. Note that the legs of Abracax are depicted as serpents.

The numerical values of the Greek letters in the Gnostic name Abrasax sum 365, the number of days in the year. This is also the number value of the Greek letters in the name Mithras, inviting the speculation that these two gods are one.

E. A. Wallis Budge wrote about this Gnostic deity: "Abrasax represented the 365 Aeons or emanations from the First Cause, and as a Pantheus, i.e. All-God, he appears on the amulets with the head of a cock (Phoebus) or of a lion (Ra or Mithras), the body of a man, and his legs are serpents which terminate in scorpions, types of the Agathodaimon. In his right hand he grasps a club, or a flail, and in his left is a round or oval shield." (Amulets and Talismans, p. 209)

It was common for the gods and goddesses of pagan religions and heretic sects to be reduced to the status of demons by Christian writers. Indeed, deities of heretic religions formed the primary source for Christian demons.
