Accordingly, the emperor again risked breaking the slender ties by which he held Egypt; he banished the popular bishop, and forced the Alexandrians to receive in his place one who held the Chalcedonian faith. On the death of Leo, he was succeeded by his grandson, Leo the Younger, who died in 473, after a reign of one year, and was succeeded by his father Zeno, the son-in-law of the elder Leo. Zeno gave himself up at once to debauchery and vice, while the empire was harassed on all sides by the barbarians, and the provinces were roused into rebellion by the cruelty of the prefects. The rebels at last found a head in Basilicus, the brother-in-law of Leo. He declared himself of the Jacobite faith, which was the faith of the barbarian enemies, of the barbarian troops, and of the barbarian allies of the empire, and, proclaiming himself emperor, made himself master of Constantinople without a battle, and drove Zeno into banishment in the third year of his reign. The first step of Basilicus was to recall from banishment Timotheus AElurus, the late Bishop of Alexandria, and to restore him to the bishopric (A.D. 477). He then addressed to him and the other recalled bishops a circular letter, in which he repeals the decrees of the council of Chalcedon, and re-establishes the Nicene creed, declaring that Jesus was of one substance with the Father, and that Mary was the mother of God. The march of Timotheus to the seat of his own government, from Constantinople whither he had been summoned, was more like that of a conqueror than of a preacher of peace. He deposed some bishops and restored others, and, as the decrees of the council of Chalcedon were the particular objects of his hatred, he restored to the city of Ephesus the patriarchal power which that synod had taken away from it. Basilicus reigned for about two years, when he was defeated and put to death by Zeno, who regained the throne. As soon as Zeno was again master of the empire, he re-established the creed of the council of Chalcedon, and drove away the Jacobite bishops from their bishoprics. Death, however, removed Timotheus AElurus before the emperor's orders were put in force in Alexandria, and the Egyptians then chose Peter Mongus as his successor, in direct opposition to the orders from Constantinople. But the emperor was resolved not to be beaten; the bishopric of Alexandria was so much a civil office that to have given up the appointment to the Egyptians would have been to allow the people to govern themselves; so he banished Peter, and recalled to the head of the Church Timotheus Salophaciolus, who had been living at Canopus ever since his loss of the bishopric.
