Magister vs Magus - What's the difference?
magister | magus |
Master; sir: -- a title of the Middle Ages, given to a person in authority, or to one having a license from a university to teach philosophy and the liberal arts.
The possessor of a master's degree.
(common usage) magician, and derogatorily sorcerer, trickster, conjurer, charlatan
(special usage) a Zoroastrian priest
: Note : the two meanings overlap in classical usage— both derive from the Greco-Roman identification of "Zoroaster" as the "inventor" of astrology and magic. The first meaning ('magician') derives from the sense of "practitioner of the Zoroaster's craft", and the second meaning ('priest') from the sense of "practitioner of Zoroaster's religion".
