On the death of Constantius, in 361, Julian was at once acknowledged as emperor, and the Roman world was again, but for the last time, governed by a pagan. The Christians had been in power for fifty-five years under Constantine and his sons, during which time the pagans had been made to feel that their enemies had got the upper hand of them. But on the accession of Julian their places were again changed; and the Egyptians among others crowded to Constantinople to complain of injustice done by the Christian prefect and bishop, and to pray for a redress of wrongs. They were, however, sadly disappointed in their emperor; he put them off with an unfeeling joke; he ordered them to meet him at Chalcedon on the other side of the straits of Constantinople, and, instead of following them according to his promise, he gave orders that no vessel should bring an Egyptian from Chalcedon to the capital; and the Egyptians, after wasting their time and money, returned home in despair. But though their complaints were laughed at, they were not overlooked, and the author of their grievances was punished; Artemius, the prefect of Egypt, was summoned to Chalcedon, and not being able to disprove the crimes laid to his charge by the Alexandrians, he paid his life as the forfeit for his mis-government during the last reign. While Artemius was on his trial the pagans of Alexandria remained quiet, and in daily fear of his return to power, for after their treatment at Chalcedon they by no means felt sure of what would be the emperor's policy in matters of religion; but they no sooner heard of the death of Artemius than they took it as a sign that they had full leave to revenge themselves on the Christians. The mob rose first against the Bishop George, who had lately been careless or wanton enough publicly to declare his regret that any of their temples should be allowed to stand; and they seized him in the streets and trampled him to death. They next slew Dracontius, the prefect of the Alexandrian mint, whom they accused of overturning a pagan altar within that building. Their anger was then turned against Diodorus, who was employed in building a church on a waste spot of ground that had once been sacred to the worship of Mithra, but had since been given by the Emperor Constantius to the Christians. In clearing the ground, the workmen had turned up a number of human bones that had been buried there in former ages, and these had been brought forward by the Christians in reproach against the pagans as so many proofs of human sacrifices. In his Christian zeal, Diodorus also had wounded at the same time their pride and superstition by cutting off the single lock from the heads of the young Egyptians. This lock had in the time of Ramses been the mark of youthful royalty; under the Ptolemies the mark of high rank; but was now common to all. Diodorus treated it as an offence against his religion. For this he was attacked and killed, with George and Dracontius.
