Articles relating to Magi, priests in Zoroastrianism and the earlier religions of the western Iranians. Pervasive throughout the Eastern Mediterranean and Western Asia until late antiquity and beyond, mágos was influenced by (and eventually displaced) Greek goēs (γόης), the older word for a practitioner of magic, to include astronomy/astrology, alchemy and other forms of esoteric knowledge. This association was in turn the product of the Hellenistic fascination for Pseudo-Zoroaster, who was perceived by the Greeks to be the Chaldean founder of the Magi and inventor of both astrology and magic, a meaning that still survives in the modern-day words "magic" and "magician".
