3. A bishop of Heracleia in Thrace, and a follower of the heresy of Macedonius, was one of the earliest writers on ecclesiastical councils. His work, entitled Συναγωγὴ τῶν Συνοδῶν
, is frequently quoted by Socrates and other ecclesiastical historians. (Soc. H. E.
1.5, 2.11, 13, 16; Sozom. H. E.
Praef.; Niceph. Call. ix.; Epiphan. Haer.
2.8, 9, 17.)
He appears to have lived about the end of the reign of Theodosius II., who reigned from A. D. 424 to 450. (Vossius, de Hist. Graec.
pp. 307, 314, 494; Fabric. Bibl. Graec.
vol. xii. pp. 182,183.)
