Baphomet was said to have been worshipped by the inner circles of several occult brotherhoods in the Middle Ages, a d was identified with the Devil card of The Tarot by by magickal philosopher Eliphas Levi.

Satanists and Devil-Worshipping cults revere the symbol of Baphomet. In the 19th century Eliphas Levi erroneously inverted the pentacle inscribing within it the head of the goat with horns. He described it as the goat of lust battering the Heavens with its horns. The Church of Satan founded in America in 1966, adopted the Baphomet as its symbol. It is inscribed in an inverted pentacle with the goat's head and symbols of the Kabbalah spelling "Leviathan."

The symbol of Baphomet, also known as the mysterious "Bearded Demon" and the "Satanic Coat," has often been misinterpreted as one of The Craft. However, Wiccan and Pagan do not use this symbol in our rituals. In fact, we do not believe in or worship The Devil created by the Christian faith as a way to discredit the Horned God, known as Herne or Cernunnos.
