ORMAZD, or Ormuzd (O. Persian Auramazda or Ahuramazda), the supreme deity of Zoroastrianism. He is represented as the god and creator of good, light, intelligence, in perpetual opposition to Ahriman the lord of evil, darkness and ignorance. The dualism of the earlier Zoroastrians, which may be compared with the Christian doctrine of God and Satan, gradually tended in later times towards monotheism. At all times it was believed that Ormazd would ultimately vanquish Ahriman. See further Zoroaster.
