The country between the Euphrates and the Tigris, called Mesopotamia, or _between the rivers_, consisted of a region about five hundred miles long and fifty wide. It was an exceedingly fertile plain. The inhabitants called themselves Assyrians. Being wealthy and numerous, and far distant from the central power of Rome, they had not only raised the banner of revolt against the empire, but had sent large armies across the Euphrates, which ravaged the adjacent provinces, and returned enriched with plunder and slaves. To bring these Assyrians again into subjection to the Roman power, Julian commenced a campaign against them. He took with him sixty-five thousand veteran Roman soldiers and a vast body of Scythian auxiliaries and roving Arabs. Eleven hundred barges crowded the Euphrates, to float down the stream the emperor’s ponderous engines of war and his military supplies. These boats, flat-bottomed, were easily converted into pontoon-bridges. As this immense army crossed the Euphrates, and entered Assyria, Julian gathered the whole body around him, and, with the most imposing rites of pagan religion, offered sacrifices to the pagan gods, appealing to them for aid in his enterprise. The appeal, for a time, seemed not to be in vain. Signal success accompanied his arms. City after city fell before the terrible power of the Roman legions. The trail of the victorious army was marked by smouldering ruins and blood. Maogamalcha was one of the most important cities of this Assyrian realm. The wolfish Roman legions burst through the gates. Every conceivable outrage was inflicted upon the wretched inhabitants, and then they were consigned to indiscriminate massacre. The governor of the city was burned alive. There were in the suburbs three palaces, enriched with every thing which could minister to the pride of an Eastern monarch. Palaces, gardens, parks, statuary, paintings,――all were reduced to utter ruin. The devastation of a palace creates much emotion; but it is the burning of the cottage, of which history takes such little notice, which fills the world with weeping and woe. Julian became such a terror to this whole region, that the painters of the nation represented him as a lion vomiting fire. And yet this same man seemed to have his appetites and passions under perfect control: he was quite free from many of those vices which degrade humanity; he shared all the hardships of the soldiers, often traversing with them, on foot, the burning plains. But ere long the heathen gods, whose aid he had implored, and upon whom he had relied, seemed to abandon him. He was led to adopt the most insane measures, which could only result in his ruin. Troubles gathered thickly around him. He became so harassed with anxiety, that he could not sleep. One night, in troubled dreams, or in a revery, an angel appeared before him weeping, and covered with a funereal veil.
