In Egypt, when Timothy III died, Theodora enlisted the help of Dioscoros, the Augustal Prefect, and Aristomachos the duke of Egypt, to facilitate the enthronement of a disciple of Severus, Theodosius, thereby outmaneuvering her husband, who had intended a Chalcedonian successor as patriarch. But Pope Theodosius I of Alexandria, even with the help of imperial troops, could not hold his ground in Alexandria against Justinian's Chalcedonian followers. When he was exiled by Justinian along with 300 Miaphysites to the fortress of Delcus in Thrace, Theodora rescued him and brought him to the Hormisdas Palace. He lived under her protection and, after her death in 548, under Justinian's.
