The earliest form of the Median religion is to be found in those sections of the Zendavesta which have been pronounced on internal evidence to be the most ancient portions of that venerable compilation; as, for instance, the first Fargard of the Vendidad, and the Gathas, or “Songs,” which occur here and there in the Yacna, or Book on Sacrifice. In the Gathas, which belong to a very remote era indeed, we seem to have the first beginnings of the Religion. We may indeed go back by their aid to a time anterior to themselves--a time when the Arian race was not yet separated into two branches, and the Easterns and Westerns, the Indians and Iranians, had not yet adopted the conflicting creeds of Zoroastrianism and Brahminism. At that remote period we seem to see prevailing a polytheistic nature-worship--a recognition of various divine beings, called indifferently Asuras (Ahuras) or Devas, each independent of the rest, and all seemingly nature-powers rather than persons, whereof the chief are Indra, Storm or Thunder; Mithra, Sunlight; Aramati (Armaiti), Earth; Vayu, Wind; Agni, Fire; and Soma (Homa), Intoxication. Worship is conducted by priests, who are called _kavi_, “seers;” _karapani_, “sacriflcers,” or _ricikhs_, “wise men.” It consists of hymns in honor of the gods; sacrifices, bloody and unbloody, some’ portion of which is burnt upon an altar; and a peculiar ceremony, called that of Soma, in which an intoxicating liquor is offered to the gods, and then consumed by the priests, who drink till they are drunken.
