(1.) an imaginary bishop of Corinth, referred to by Prsedestinatus (i, 23).
(2.) An imaginary bishop of Ephesus (ibid. 26, 27). He is perhaps the same spoken-of by St. Jerome as a person of great wisdom who lived about the end of the 2d century, under the emperors Commodus and Severus. He wrote in Greek against the heresiarch Montanus, and Priscilla and Maxilla, the two women whom he induced to forsake their husbands and to follow him as his prophetesses. He reproached them for their avarice, and ridiculed their doctrine and their prophecies. A fragment of this work will be found in Eusebius, lib. v, cap. 18. Tertullian, after his fall, wrote a book, now lost-the seventh book De Ecstasi--which was specially directed against this work of Apollonius. One writer makes Apollonius to have been bishop of Antioch; but nothing at all certain is known about his country. See Cave, Hist. Lit. I, i, 86.--Landon, Eccles. Diet. s.v. (3.) A " companion" of one of the Antonines, who vainly tried to persuade Bardeisan to abjure Christianity (Epiphanius, Haer. 477). (4.) A correspondent of Theodoret, probably not a Christian, to whom he wrote, commending the excellence of his natural endowments, and urging an acknowledgment of the Giver (Theodoret, iEp. 73). (5.) Count, praefect of the East in 442, and great chamberlain, to whom Theodoret wrote with reference to the calumnies spread against him at Constantinople (ibid. 103). He was in office at the Council of Chalcedon, 451 (Labbe, Concil. 4:851, etc.).
