    • n Zoroastrianism The system of religious doctrine taught by Zoroaster and his followers in the Avesta; the religion prevalent in Persia till its overthrow by the Mohammedans in the seventh century, and still held by the Guebers and Parsees, and commonly, though incorrectly, called fire-worship. The religion is dual, recognizing two creative powers—Ormuzd (Ahuramazda), the god of light and creator of all that is good, with six principal and innumerable inferior amshaspands, or ministers of good, and Ahriman (Angramainyus), the god of darkness and creator of evil, with a corresponding number of devs, or ministers of evil. Zoroaster taught that Ormuzd created man with free will; that his state after death depends upon the preponderance of good or evil in his life, an intermediate state being provided for those in whom these principles are evenly balanced; and that Ormuzd will finally prevail over Ahriman in the constant war between them, and redeem him and his ministers, as well as man, from all evil.
