(singular magus) Priests of the Zoroastrian religion of ancient Persia, noted for their knowledge of astrology. The term is used in the New Testament of the Latin Vulgate Bible where the King James Version gives “wise men”. The magi who came to visit the infant Jesus with gifts of gold, frankincense, and myrrh (the Adoration of the Magi) were in later tradition described as “the three kings”—Caspar, Melchior, and Balthazar.
