Ecclesiastical History

On war being waged against the Romans by Sapor King of Persia, Constantius mustered his forces and marched to Antioch. But the enemy were driven forth, not by the Roman army, but by Him whom the pious in the Roman host worshipped as their God. How the victory was won I shall now proceed to relate.

Nisibis, sometimes called Antiochia Mygdonia, lies on the confines of the realms of Persia and of Rome. In Nisibis Jacobus whom I named just now was at once bishop, guardian, and commander in chief. He was a man who shone with the grace of a truly apostolic character. His extraordinary and memorable miracles, which I have fully related in my religious history, I think it superfluous and irrelevant to enumerate again.

One however I will record because of the subject before us. The city which Jacobus ruled was now in possession of the Romans, and besieged by the Persian Army. The blockade was prolonged for seventy days. “Helepoles” and many other engines were advanced to the walls. The town was begirt with a palisade and entrenchment, but still held out. The river Mygdonius flowing through the middle of the town, at last the Persians dammed its stream a considerable distance up, and increased the height of its bank on both sides so as to shut the waters in. When they saw that a great mass of water was collected and already beginning to overflow the dam, they suddenly launched it like an engine against the wall. The impact was tremendous; the bulwarks could not sustain it, but gave way and fell down. Just the same fate befell the other side of the circuit, through which the Mygdonius made its exit; it could not withstand the shock, and was carried away. No sooner did Sapor see this than he expected to capture the rest of the city, and for all that day he rested for the mud to dry and the river to become passable. Next day he attacked in full force, and looked to enter the city through the breaches that had been made. But he found the wall built up on both sides, and all his labour vain. For that holy man, through prayer, filled with valour both the troops and the rest of the townsfolk, and both built the walls, withstood the engines, and beat off the advancing foe. And all this he did without approaching the walls, but by beseeching the Lord of all within the church. Sapor, moreover, was not only astounded at the speed of the building of the walls but awed by another spectacle. For he saw standing on the battlements one of kingly mien and all ablaze with purple robe and crown. He supposed that this was the Roman emperor, and threatened his attendants with death for not having announced the imperial presence; but on their stoutly maintaining that their report had been a true one and that Constantius was at Antioch, he perceived the meaning of the vision and exclaimed “their God is fighting for the Romans.” Then the wretched man in a rage flung a javelin into the air, though he knew that he could not hit a bodiless being, but unable to curb his passion. Therefore the excellent Ephraim (he is the best writer among the Syrians) besought the divine Jacobus to mount the wall to see the barbarians and to let fly at them the darts of his curse. So the divine man consented and climbed up into a tower but when he saw the innumerable host he discharged no other curse than to that mosquitoes and gnats might be sent forth upon them, so that by means of these tiny animals they might learn the might of the Protector of the Romans. On his prayer followed clouds of mosquitoes and gnats; they filled the hollow trunks of the elephants, and the ears and nostrils of horses and other animals. Finding the attack of these little creatures past endurance they broke their bridles, unseated their riders and threw the ranks into confusion. The Persians abandoned their camp and fled head-long. So the wretched prince learned by a slight and kindly chastisement the power of the God who protects the pious, and marched his army home again, reaping for all the harvest of the siege not triumph but disgrace.
