Belisarius took no account of the oaths which he had sworn, and made no effort to avenge Photius's sufferings, in spite of the solemn vows which he had made to do so. Hereafter, probably by God's will, all his warlike enterprises failed. Some time afterwards he was dispatched against the Medes and Chosroes, who had for the third time invaded the Roman Empire, and fell under suspicion of treachery, although he was considered to have performed a notable achievement in driving the enemy away from the frontier; but when Chosroes, after crossing the Euphrates, took the populous city of Callinikus without a blow, and made slaves of tens of thousands of Romans, Belisarius remained quiet, and never so much as offered to attack the enemy, whereby he incurred the reproach of either treachery or cowardice. CHAPTER IV About this time Belisarius underwent another disgrace. The people of Byzantium were ravaged by the pestilence of which I have already spoken. The Emperor Justinian was attacked by it so severely that it was reported that he had died. Rumour spread these tidings abroad till they reached the Roman camp, whereupon some of the chief officers said that, if the Romans set up any other emperor in Byzantium, they would not acknowledge him. Shortly after this, the Emperor recovered from his malady, whereupon the chiefs of the army accused one another of having used this language. The General Peter, and John, surnamed "The Glutton," declared that Belisarius and Buzes had used the words which I have just quoted. The Empress Theodora, thinking that these words applied to herself, was greatly enraged. She straightway summoned all the commanders to Byzantium to make an inquiry into the matter, and suddenly sent for Buzes to come into her private apartments, on the pretext of discussing important matters of business with him. There was in the palace an underground building, which was securely fastened, and as complicated as a labyrinth, and which might be compared to the nether world, wherein she kept imprisoned most of those who had offended her. Into this pit she cast Buzes; and although he was of a consular family, nothing was known for certain concerning him; as he sat in the darkness, he could not tell day from night; nor could he ask, for he who flung him his daily food never spoke, but acted like one dumb beast with another. All thought him dead, but none dared to mention him or allude to him. Two years and four months afterwards, Theodora relented and released him, and he appeared in the world like one raised from the dead; but ever afterwards he was short-sighted and diseased in body. Such was the fate of Buzes.
