APION, Greek grammarian and commentator on Homer, born at Oasis in Libya. He was head of the school at Alexandria and led a deputation sent to Caligula (in A.D. 38) by the Alexandrians to complain of the Jews (see Philo, head of the Jewish deputa tion, Legatio ad Gaium). The charges which he brought in his books against the Jews were answered by Josephus in his Contra Apionem. He settled at Rome and taught rhetoric till the reign of Claudius. The story of Androclus and the lion, preserved in Aulus Gellius, is from his Alytnrriarca; fragments of his I'Awvaac are printed in the Etymologicum Gudianum, ed. Sturz (1818).
