with disdain under the foreign government. The command of the army was bestowed on Artavasdes, whose father had saved the infancy of Tiridates, and whose family had been massacred for that generous action. The brother of Artavasdes obtained the government of a province. One of the first military dignities was conferred on the satrap Otas, a man of singular temperance and fortitude, who presented to the king his sister and a considerable treasure, both of which, in a sequestered fortress, Otas had preserved from violation. Among the Armenian nobles appeared an ally, whose fortunes are too remarkable to pass unnoticed. His name was Mamgo, his origin was Scythian, and the horde which acknowledge his authority had encamped a very few years before on the skirts of the Chinese empire, which at that time extended as far as the neighborhood of Sogdiana. Having incurred the displeasure of his master, Mamgo, with his followers, retired to the banks of the Oxus, and implored the protection of Sapor. The emperor of China claimed the fugitive, and alleged the rights of sovereignty. The Persian monarch pleaded the laws of hospitality, and with some difficulty avoided a war, by the promise that he would banish Mamgo to the uttermost parts of the West, a punishment, as he described it, not less dreadful than death itself. Armenia was chosen for the place of exile, and a large district was assigned to the Scythian horde, on which they might feed their flocks and herds, and remove their encampment from one place to another, according to the different seasons of the year. They were employed to repel the invasion of Tiridates; but their leader, after weighing the obligations and injuries which he had received from the Persian monarch, resolved to abandon his party. The Armenian prince, who was well acquainted with this merit as well as power of Mamgo, treated him with distinguished respect; and, by admitting him into his confidence, acquired a brave and faithful servant, who contributed very effectually to his restoration.

For a while, fortune appeared to favor the enterprising valor of Tiridates. He not only expelled the enemies of his family and country from the whole extent of Armenia, but in the prosecution of his revenge he carried his arms, or at least his incursions, into the heart of Assyria. The historian, who has preserved the name of Tiridates from oblivion, celebrates, with a degree of national enthusiasm, his personal prowess: and, in the true spirit of eastern romance, describes the giants and the elephants that fell beneath his invincible arm. It is from other information that we discover the distracted state of the Persian monarchy, to which the king of Armenia was indebted for some part of his advantages. The throne was disputed by the ambition of contending brothers; and Hormuz, after exerting without success the strength of his own party, had recourse to the dangerous assistance of the barbarians who inhabited the banks of the Caspian Sea. The civil war was, however, soon terminated, either by a victor or by a reconciliation; and Narses, who was universally acknowledged as king of Persia, directed his whole force against the foreign enemy. The contest then became too unequal; nor was the valor of the hero able to withstand the power of the monarch, Tiridates, a second time expelled from the throne of Armenia, once more took refuge in the court of the emperors. * Narses soon reestablished his authority over the revolted province; and loudly complaining of the protection afforded by the Romans to rebels and fugitives, aspired to the conquest of the East.

Neither prudence nor honor could permit the emperors to forsake the cause of the Armenian king, and it was resolved to exert the force of the empire in the Persian war. Diocletian, with the calm dignity which he constantly assumed, fixed his own station in the city of Antioch, from whence he prepared and directed the military operations. The conduct of the legions was intrusted to the intrepid valor of Galerius, who, for that important purpose, was removed from the banks of the Danube to those of the Euphrates. The armies soon encountered each other in the plains of Mesopotamia, and two battles were fought with various and doubtful success; but the third engagement was of a more decisive nature; and the Roman army received a total overthrow, which is attributed to the rashness of Galerius, who, with an inconsiderable body of troops, attacked the innumerable host of the Persians. But the consideration of the country that was the scene of action, may suggest another reason for his defeat. The same ground on which Galerius was vanquished, had been rendered memorable by the death of Crassus, and the slaughter of ten legions. It was a plain of more than sixty miles, which extended from the hills of Carrhæ to the Euphrates; a smooth and barren surface of sandy desert, without a hillock, without a tree, and without a spring of fresh water. The steady infantry of the Romans, fainting with heat and thirst, could neither hope for victory if they preserved their ranks, nor break their ranks without exposing themselves to the most imminent danger. In this situation they were gradually encompassed by the superior numbers, harassed by the rapid evolutions,
