the part of the troops, and of resistance on the part of the people, the whole city was thrown into an uproar, and the prefect was hardly strong enough to carry on the government; the regular supply of grain for the poor citizens of Alexandria, and for Constantinople, was stopped; and the blame of the whole thrown upon Athanasius.  He was a second time obliged to leave Egypt, and he fled to Rome, where he was warmly received by the Emperor Constans and the Roman bishop.  But the zeal of the Athanasian party would not allow Gregory to keep possession of the church which he had gained only by force; they soon afterwards set fire to it and burned it to the ground, choosing that there should be no church at all rather than that it should be in the hands of the Arians; and the Arian clergy and bishops, though supported by the favour of the emperor and the troops of the prefect, were everywhere throughout Egypt driven from their churches and monasteries.  During this quarrel it seems to have been felt by both parties that the choice of the people, or at least of the clergy, was necessary to make a bishop, and that Gregory had very little claim to that rank in Alexandria.  Julius, the Bishop of Rome, warmly espoused the cause of Athanasius, and he wrote a letter to the Alexandrian church, praising their zeal for their bishop, and ordering them to re-admit him to his former rank, from which he had been deposed by the council of Antioch, but to which he had been restored by the Western bishops.  Athanasius was also warmly supported by Constans, the emperor of the West, who at the same time wrote to his brother Constantius, begging him to replace the Alexandrian bishop, and making the additional threat that if he would not reinstate him he should be made to do so by force of arms.

Constantius, after taking the advice of his own bishops, thought it wisest to yield to the wishes or rather the commands of his brother Constans, and he wrote to Athanasius, calling him into his presence in Constantinople.  But the rebellious bishop was not willing to trust himself within the reach of his offended sovereign; and it was not till after a second and a third letter, pressing him to come and promising him his safety, that he ventured within the limits of the Eastern empire.  Strong in his high character for learning, firmness, and political skill, carrying with him the allegiance of the Egyptian nation, which was yielded to him much rather than to the emperor, and backed by the threats of Constans, Athanasius was at least a match for Constantius.  At Constantinople the emperor and his subject, the Alexandrian bishop, made a formal treaty, by which it was agreed that, if Constantius would allow the Homoousian clergy throughout his dominions to return to their churches, Athanasius would in the same way throughout Egypt restore the Arian clergy; and upon this agreement Athanasius himself returned to Alexandria.
