Among the Chaldeans the most famous name is that of Zoroaster, who is
held to have been the author of their religion, their civil policy,
their sciences, and their magic. He taught the doctrine of two great
principles, the one the author of good, the other of evil. He
prohibited the use of images in the ceremonies of religion, and
pronounced that nothing deserved homage but fire, and the sun, the
centre and the source of fire, and these perhaps to be venerated not
for themselves, but as emblematical of the principle of all good
things. He taught astronomy and astrology. We may with sufficient
probability infer his doctrines from those of the Magi, who were his
followers. He practised enchantments, by means of which he would send
a panic among the forces that were brought to make war against him,
rendering the conflict by force of arms unnecessary. He prescribed the
use of certain herbs as all-powerful for the production of supernatural
effects. He pretended to the faculty of working miracles, and of
superseding and altering the ordinary course of nature.--There was,
beside the Chaldean Zoroaster, a Persian known by the same name, who
is said to have been a contemporary of Darius Hystaspes.
