Lucianus, the presbyter of Antioch, who became the head of the theological school of that city in which the leaders of the Arian heresy were trained, after the deposition of Paulus refused to hold communion with his three successors in the patriarchate, Domnus, Timæus, and Cyril. During the episcopate of the last named he once more entered into communion with the church of Antioch. On the importance of Lucianus as founder of the Arians, Vide Newman’s Arians of the Fourth Century, Chap. I. Sec. i. and cf. the letter of Arius post. Chap. iv.
