EUSTATHIUS, yu-stê'thi-us, OF ANTIOCH : Bishop of Antioch; d. probably c. 337. He was apparently a native of Side in Pamphylia, was bishop of Bera about 320, and was transferred to Antioch before the first Council of Nicæa. He was one of the few decided anti-Arians in the East, and carried on a literary polemic against Eusebius of Cæsarea (q.v.) which made him well hated by the unorthodox party. They succeeded in effecting his deposition in 330, and he was banished to Trajanopolis in Thrace, where he died and was buried. Jerome says that "he composed many works against the doctrine of the Arians"; but only one is preserved entire, De Engastrimytho contra Origenem (best edition by Jahn, TU, ii. 4, Tübingen, 1886). Fragments are preserved of a De anima mentioned by Jerome ; of another work in eight books Contra Arianos; of treatises on Prov. viii. 22 and ix. 5; of one on Melchisedek; of two In inscriptiones psalmorum ; and of expositions of certain separate psalms. The commentary on the first part of Genesis (MPG, xviii. 705-1066) is generally considered spurious, and the "Liturgy of St. Eustathius" (ib. 697-704 is hardly more authentic.
