Magic appears to have had its origin on the plains of Assyria, and the worship of the stars was the creed of those pastoral tribes who, pouring down from the mountains of Kurdistan into the wide level where Babylon afterwards raised its thousand towers, founded the sacerdotal race of the _Chasdim_ or _Chaldeans_. To these men were soon alloted peculiar privileges and ascribed peculiar attributes, until, under the name of Magi, they acquired a vast and permanent influence. Their temples were astronomical observatories as well as holy places; and the legendary tower of Babel, in the Book of Genesis, is probably but the mythical equivalent of a vast edifice consecrated to the study of the seven planets, or perhaps, as the _Bab_ (court or palace) of _Bel_, to the brilliant star of good fortune alone. Availing themselves of the general adoration of the stars, they appear to have invented a system of astrology--the apotelesmatic science--by which they professed to decide upon the nature of coming events and the complexion of individual fortunes, with especial reference to the planetary aspects. In Persia magic assumed a yet more definite development. The Chaldeans had attributed the origin of all things to a great central everlasting fire. The foundation of the Persian system, usually ascribed to Zerdusht or Zoroaster, was the existence of two antagonistic principles--Ormuzd, the principle of good, and Ahriman, the principle of evil. In Persia everything associated with science or religion was included under the denomination "magic." The Persian priests were named the Magnise or Magi, but they did not arrogate to themselves the entire credit of intercourse with the gods. Zoroaster, who was King of Bactria, made some reservations for the sake of exalting the regal power, and taught that the kings were illuminated by a celestial fire which emanated from Ormuzd. Hence the sacred fire always preceded the monarch as a symbol of his illustrious rank; and Plato says the Persian kings studied magic, which is a worship of their gods.
