2. Bishop of Hierapolis, A. D. 431. He was sent by John, bishop of Antioch, to advocate the cause of Nestorius at the Council of Ephesus. His hostility to St. Cyril was such, that he openly charged him with Apollinaranism, and rejected the communion of John, Theodoret, and the other Eastern bishops, on their reconciliation with him. He appealed to the pope, but was rejected, and was at last banished by the emperor to Famothis in Egypt. Twenty-three letters of his are extant in Latin in the p. 670, &c. Paris, 1683.
