Aphtho'nius
(
*)Afqo/nios) of Alexandria is mentioned by Philostorgius (3.15) as a learned and eloquent bishop of the Manichacans.
He is mentioned as a disciple and commentator of Mani by Photius and Peter of Sicily, and in the form of abjuring Manichaeism. Philostorgius adds, that Aetius had a public disputation with Aphthonius, in which the latter was defeated, and died of grief seven days afterwards.
