Magus (n.)

c. 1200, "skilled magicians, astrologers," from Latin magi, plural of magus "magician, learned magician," from Greek magos, a word used for the Persian learned and priestly class as portrayed in the Bible (said by ancient historians to have been originally the name of a Median tribe), from Old Persian magush "magician" (see magic). Also, in Christian history, the "wise men" who, according to Matthew, came from the east to Jerusalem to do homage to the newborn Christ (late 14c.). Related: Magian.
