surnamed, probably from his occupation, MAGISTER, was a schoolmaster and grammarian, teaching Greek to Roman youths. He lived under Septimius Severus and Ant. Caracalla, about the beginning of the third century of our era. This appears by a passage in his Ἑρμηνεύματα, where he states that he copied the Geneologia of Hyginus in the consulship of Maximus and Aprus, which occurred A. D. 207.
