and from springs. But when his devices came to nothing effectual for him, he devised something else. 36 Having gone up the river, which, as has been said, flowed through the city, and having come to the ravines, where the place through which it flowed was narrow, he blocked the place and held back its current. And when the water flooded, suddenly removing the things blocking the outlet of the water, he released the current against the city; and it, having accumulated in great quantity and falling upon the wall with violent force, broke down a part of it. But the barbarian did not immediately enter the city, but as if it were already captured, since it was also toward evening, he postponed taking the city until the morrow, with no one opposing. But those in the city were thrown into confusion by the breach of the wall, but when they saw the Persians postponing their entry, they spent the night sleeplessly and with many hands fortified the place, raising another wall within. When Sapor saw this in the morning, he attributed the misfortune to his own carelessness. But not even so did he desist from the siege. And having devised many other things against the city and having lost very many of his own men (for it is said that over twenty thousand of the Persian army perished while Nisibis was being besieged), he withdrew with shame. For already 37 the Massagetae had also attacked Persia and were ravaging it. But the emperor Constantius fortified Nisibis and won back its citizens, and he himself, since a truce with the Persians had now been made in the East, set out for the western regions. And it is announced to him that Vetranio had made common cause with Magnentius. For this man, being commander of the armies in Illyricum and learning of Magnentius' rebellion and the murder of Constans, did not submit to the one who had become tyrant, but he himself on the other hand had attempted a tyranny. And writing to Constantius he said that he was opposing the tyrant and urged him to come for his overthrow. Therefore Vetranio and Magnentius, having made a truce with each other on terms, both send envoys jointly to Constantius, asking him to lay down his arms and to hold the first honor. So the envoys, meeting the emperor near Heraclea in Thrace, reported to him what had been communicated. And he, becoming concerned because of these things, when night came on, sees such a dream. It seemed that his father 38 stood beside him, holding his son Constans by the hand, and said to him: "Constantius, behold Constans your brother, descendant of many emperors, who perished by a tyrant. It is necessary, therefore, for you both to avenge him and not to overlook the empire being broken apart nor the state being overthrown, but to hasten to destroy the tyranny and not to allow your brother to go unavenged." Upon this Constantius, having woken up, detained the envoys and handed them over to a guard; and he himself, delaying not at all, immediately arrives at Sardica. And Vetranio, dismayed at the unexpected arrival of Constantius, went to meet him as his master, having both abandoned his former plans and broken his treaty with Magnentius. And Constantius received him genuinely and made him a companion at his table. For Vetranio, having laid aside the insignia of imperial power, in the dress of a private citizen, took hold of the emperor's feet. And he both embraced Vetranio and called him father, and extending a hand to him and supporting him as he was an old man, he made him a dinner companion 39; then Prusa (this is a city of the Bithynians) was set apart for him as a residence and lands were assigned for the supply of his necessities. There, living in luxury for six years, he ended his life. And the affairs concerning Vetranio came to such an end; but the emperor Constantius set out against Magnentius. He was staying in Mediolanum, having proclaimed his brother Decentius as Caesar and having sent him to guard the Gallic provinces. Meanwhile Sapor again, seizing the opportunity, plundered the eastern regions and, taking booty and many captives, returned. Thus on both sides the emperor, being surrounded by the from
