The Nubians were far more civilised than their neighbours, the Blemmyes, whom they were usually able to drive back into their native deserts. We find an inscription in bad Greek, in the great temple at Talmis, now the village of Kalabshe, which was probably written about this time. A conqueror of the name of Silco there declares that he is king of the Nubians and all the Ethiopians; that in the upper part of his kingdom he is called Mars, and in the lower part Lion; that he is as great as any king of his day; that he has defeated the Blemmyes in battle again and again; and that he has made himself master of the country between Talmis and Primis. While such were the neighbours and inhabitants of the Thebaid, the fields were only half-tilled, and the desert was encroaching on the paths of man. The sand was filling up the temples, covering the overthrown statues, and blocking up the doors to the tombs; but it was at the same time saving, to be dug out in after ages, those records which the living no longer valued. On the death of the Emperor Marcian, the Alexandrians, taking advantage of the absence of the military prefect Dionysius, who was then fighting against the Nubades in Upper Egypt, renewed their attack upon the Bishop Proterius, and deposed him from his office. To fill his place they made choice of a monk named Timotheus AElurus, who held the Jacobite faith, and, having among them two deposed bishops, they got them to ordain him Bishop of Alexandria, and then led him by force of arms into the great church which had formerly been called Caesar's temple. Upon hearing of the rebellion, the prefect returned in haste to Alexandria; but his approach was only the signal for greater violence, and the enraged people murdered Proterius in the baptistery, and hung up his body at the Tetrapylon in mockery. This was not a rebellion of the mob. Timotheus was supported by the men of chief rank in the city; the _Honorati_ who had borne state offices, the _Politici_ who had borne civic offices, and the _Navicularii_, or contractors for the freight of the Egyptian tribute, were all opposed to the emperor's claim to appoint the officer whose duties were much more those of prefect of the city than patriarch of Egypt. With such an opposition as this, the emperor would do nothing without the greatest caution, for he was in danger of losing Egypt altogether. But so much were the minds of all men then engrossed in ecclesiastical matters that this political struggle wholly took the form of a dispute in controversial divinity, and the emperor wrote a letter to the chief bishops in Christendom to ask their advice in his difficulty. These theologians were too busily engaged in their controversies to take any notice of the danger of Egypt's revolting from the empire and joining the Persians; so they strongly advised Leo not to depart from the decrees of the council of Chalcedon, or to acknowledge as Bishop of Alexandria a man who denied the two natures of Christ.
