Also known as the "Sabbatic Goat
An excellent picture of Baphomet (and a classic on at that) may be found in Eliphas Levi's Trancendental Magic (Translated by A.E. Waite). There he is shown sitting upon a cube (the symbol of Salt, also of Malkuth). His legs are crossed, one hand points upward-the other downward; each indicating a Light and Dark Moon. Between his great horns rests a burning torch. Baphomet has both breasts and a phallus, these are complimented by two feathery wings.
Upon assuming the position of Supreme and Holy King in the O.T.O., Aleister Crowley took on the name Baphomet and upon speaking the Word of the Aeon, began to spread the doctrine of Thelema.
