Ormazd \Or"mazd\or Ahura-Mazda \A`hu*ra-Maz"da\, n. [Zend
   Ahuramazda.] (Zoroastrianism)
   The supreme deity, the principle of good, creator of the
   world, and guardian of mankind. He is the opponent of
   Ahriman, the spirit of evil, both being sprung from Eternity,
   or, according to another version, Ahriman being the offspring
   of a moment of doubt on the part of Ormazd. Ormazd is
   attended by angels and archangels. He is represented as a
   bearded man inclosed in a winged circle, a conception
   probably derived from the Assyrian representations of Ashur.
