God of a Roman mystery cult.
He was originally a Hittite-Hurrian god of fertility and thunder worshiped at Doliche in Anatolia. He also became identified with the Zoroastrian god Ahura Mazda as a lord of the universe. Returning legions carried his cult to Rome, where it became popular in the 2nd–3rd century AD. In Roman mystery religion he was believed to control military success and safety. He was usually represented standing on a bull holding a double ax and thunderbolt.
