under the walls of Amida, during the continuance of a siege, which lasted seventy-three days; and the disappointed monarch returned to his capital with affected triumph and secret mortification. It is more than probable, that the inconstancy of his Barbarian allies was tempted to relinquish a war in which they had encountered such unexpected difficulties; and that the aged king of the Chionites, satiated with revenge, turned away with horror from a scene of action where he had been deprived of the hope of his family and nation. The strength as well as the spirit of the army with which Sapor took the field in the ensuing spring was no longer equal to the unbounded views of his ambition. Instead of aspiring to the conquest of the East, he was obliged to content himself with the reduction of two fortified cities of Mesopotamia, Singara and Bezabde; the one situate in the midst of a sandy desert, the other in a small peninsula, surrounded almost on every side by the deep and rapid stream of the Tigris. Five Roman legions, of the diminutive size to which they had been reduced in the age of Constantine, were made prisoners, and sent into remote captivity on the extreme confines of Persia. After dismantling the walls of Singara, the conqueror abandoned that solitary and sequestered place; but he carefully restored the fortifications of Bezabde, and fixed in that important post a garrison or colony of veterans; amply supplied with every means of defence, and animated by high sentiments of honor and fidelity. Towards the close of the campaign, the arms of Sapor incurred some disgrace by an unsuccessful enterprise against Virtha, or Tecrit, a strong, or, as it was universally esteemed till the age of Tamerlane, an impregnable fortress of the independent Arabs.

The defence of the East against the arms of Sapor required and would have exercised, the abilities of the most consummate general; and it seemed fortunate for the state, that it was the actual province of the brave Ursicinus, who alone deserved the confidence of the soldiers and people. In the hour of danger, Ursicinus was removed from his station by the intrigues of the eunuchs; and the military command of the East was bestowed, by the same influence, on Sabinian, a wealthy and subtle veteran, who had attained the infirmities, without acquiring the experience, of age. By a second order, which issued from the same jealous and inconstant councils, Ursicinus was again despatched to the frontier of Mesopotamia, and condemned to sustain the labors of a war, the honors of which had been transferred to his unworthy rival. Sabinian fixed his indolent station under the walls of Edessa; and while he amused himself with the idle parade of military exercise, and moved to the sound of flutes in the Pyrrhic dance, the public defence was abandoned to the boldness and diligence of the former general of the East. But whenever Ursicinus recommended any vigorous plan of operations; when he proposed, at the head of a light and active army, to wheel round the foot of the mountains, to intercept the convoys of the enemy, to harass the wide extent of the Persian lines, and to relieve the distress of Amida; the timid and envious commander alleged, that he was restrained by his positive orders from endangering the safety of the troops. Amida was at length taken; its bravest defenders, who had escaped the sword of the Barbarians, died in the Roman camp by the hand of the executioner: and Ursicinus himself, after supporting the disgrace of a partial inquiry, was punished for the misconduct of Sabinian by the loss of his military rank. But Constantius soon experienced the truth of the prediction which honest indignation had extorted from his injured lieutenant, that as long as such maxims of government were suffered to prevail, the emperor himself would find it is no easy task to defend his eastern dominions from the invasion of a foreign enemy. When he had subdued or pacified the Barbarians of the Danube, Constantius proceeded by slow marches into the East; and after he had wept over the smoking ruins of Amida, he formed, with a powerful army, the siege of Bezabde. The walls were shaken by the reiterated efforts of the most enormous of the battering- rams; the town was reduced to the last extremity; but it was still defended by the patient and intrepid valor of the garrison, till the approach of the rainy season obliged the emperor to raise the siege, and ingloriously to retreat into his winter quarters at Antioch. The pride of Constantius, and the ingenuity of his courtiers, were at a loss to discover any materials for panegyric in the events of the Persian war; while the glory of his cousin Julian, to whose military command he had intrusted the provinces of Gaul, was proclaimed to the world in the simple and concise narrative of his exploits.

In the blind fury of civil discord, Constantius had abandoned to the Barbarians of Germany the countries of Gaul, which still acknowledged the authority of his rival. A numerous swarm of Franks and Alemanni were invited to cross the Rhine by presents and promises, by the hopes of spoil, and by a perpetual grant of all the territories which they should be able to subdue. But the emperor, who for a temporary
