EUSTATHIUS, bishop of Berea, was a native of Side in Pamphylia. By the council of Nice, in which he distinguished himself by his zeal against the Arians, he was promoted to the patriarchate of Antioch. So violent was the feeling among the Arians against him, that a synod of Arian prelates convened at Antioch brought about his deposition and banishment through a series of heavy charges founded on evidence which they themselves knew to be false. This villany was not discovered till a woman, whose evidence had told very heavily against Eustathius, confessed on her deathbed her own perjury, and that of the other witnesses, who had been suborned. Her confession came too late to benefit the deposed bishop, who had died at Trajanopolis in Thrace, A.D. 329 or 330. Of several works attributed to Eustathius there is only one which can with certainty be pronounced his—an address, namely, to the Emperor Constantine, during the sitting of the council of Nice.
