This Æmilianus, prefect of Egypt, under whom the persecution was carried on in Alexandria during Valerian’s reign, later, during the reign of Gallienus, was induced (or compelled) by the troops of Alexandria to revolt against Gallienus, and assume the purple himself. He was defeated, however, by Theodotus, Gallienus’ general, and was put to death in prison, in what year we do not know. Cf. Tillemont’s Hist. des Emp. III. p. 342 sq.
