Ahriman, the principle of evil in Persian mythology, was personified as Angra Mainya, "the destructive spirit," who introduced death into the world. He led the forces of evil against the host of Spenta Mainya, "the holy spirit," who assisted Ahura Mazdah, "the wise lord" and final victor in the cosmic war.
