Anianus a native of Campania and ardent adherent of Pelagius, whose cause he defended at the council of Diospolis in 415. He wrote a work, Contra Elpistolca Hieronymni ad Ctesphontem, which is lost, and translated the homilies of Chrysostom on the Gospel of Matthew. According to the testimony of Richard Simon, Huet, and Casaubon, he was one of the ablest translators of the ancient church. His translation of Chrysostom is reprinted in the Benedictine edition. — Dupin, Eccl. Writers, vol. 3.
