d. c.408. Opponent of John Chrysostom.* Bishop of Gabala, Syria, who came to Constantinople about 401, Severian was well received by Chrysostom, but attempted to undermine the latter's authority during his absence in Asia. At the Synod of the Oak* (403), under Theophilus's influence, he acted as accuser and judge of Chrysostom. Again he accused him (404) and finally effected Chrysostom's exile to Cucusus, demanding in 407 his removal to a severer place of exile. He wrote several homilies, including six on the Hexaemeron.
