bishop of Beroea, 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.

Eustathius, archbishop of Thessalonica, was a native of Constantinople, and flourished during the latter half of the twelfth century. Such of his works as have descended to our times display a comprehensiveness and variety of erudition that fairly entitle him to the praise of being the most learned man of his day. The most important of these is his Commentary on the Iliad and Odyssey of Homer, a work valuable as comprising large extracts from the scholiæ of other critics whose works have now perished, such as Apion, Heliodorus, Aristarchus, Aristophanes of Byzantium, &c. This commentary was first published at Rome, 1542–50, in 4 vols., and was reprinted at Leipzig in 1825–29, under the editorial care of G. Stalbaum. Eustathius also wrote a Commentary on Dionysius the Geographer, first printed by Robert Stephens in 1547, and frequently reprinted since. A Commentary on Pindar, which he is known to have written, has been lost. Eustathius died in 1198. The funeral orations pronounced in his honour by Euthynius and Michael Choniates are still in MS. in the Bodleian Library.

famous Graeco-Roman jurist, who flourished at Constantinople in the latter half of the tenth century, and filled various high offices under the emperors who reigned during that period. He is frequently mentioned under the names of Patricius, Magister, and Romanus. Besides his Romanae, frequently quoted by later jurists, Eustathius wrote a number of other works never published, the MSS. of which are still extant in the Vatican at Rome, in Paris, and elsewhere.
