The English word 'magic' descends from the Old Persian maguš — a member of the Medes' priestly and scholarly caste, the Magi, who served as priests, astrologers, dream interpreters, and keepers of sacred fire in the Zoroastrian religious tradition. The Magi were one of the six tribes of the Median people and were so closely identified with religious and esoteric knowledge that their name became a synonym for those arts. The Greek historian Herodotus mentions the Magi repeatedly, noting that no Persian sacrifice was valid without a Magus present to chant the sacred hymns, and that the Magi were dream interpreters, fire tenders, and keepers of the cosmological calendar.

When Greeks encountered the Magi of Persia in the 6th–5th centuries BCE — during the Persian Wars and through diplomatic and commercial contacts — they were struck by the Magi's apparently supernatural abilities: divination, astrology, interpretation of omens, management of sacred fire, and knowledge of celestial movements. The Greek word for their practice, derived from their Persian title, was mageia — the arts of the Magi. Greek writers used mageia to describe the esoteric Persian priestly practices, but the word quickly generalized to mean any supernatural power, secret knowledge, or illusion-working. From Greek mageia came Latin magia, and from Latin the word spread through all European languages. Magic, magical, magician, mage — all trace back to the Persian priestly caste.

The Magi's most famous appearance in Western culture is in the Gospel of Matthew (2:1–12), where 'Magi from the East' follow a star to Bethlehem. The Greek text says mágoi — meaning Zoroastrian astrologer-priests from Persia or Mesopotamia, not 'three kings,' a detail the text does not provide. Medieval tradition elaborated the Magi into three named kings (Caspar, Melchior, Balthasar), but the original Matthew text describes exactly what the word means: Persian astrologer-priests, practitioners of mageia, who had read astronomical signs and traveled to investigate them.
