Wherefore Phraates, marching against them, left one Hymerus, who had recommended himself to his favour by prostituting the bloom of his youth to his infamous lust, the care of his kingdom in his absence. This governor, forgetting his past life and the trust he was charged with, miserably harassed the Babylonians, and many other cities, by his tyrannical cruelties. But Phraates himself carried along with him to the war an army of Greeks, which he had taken in the war against Antiochus, and treated with great pride and barbarity; not at all considering that their hatred to him was so far from being lessened by their captivity, that they were rather more exasperated against him by the indignity of the outrages they had suffered. Wherefore, when they saw the army of the Parthians give ground, they joined their arms with those of the enemy, and executed their long wished-for revenge for their captivity by the bloody havoc they made on the Parthian army, and by the death of King Phraates himself. Artabanus his uncle was made king in his room; but the Scythians being content with victory, having laid waste Parthia, returned home. But Artabanus, in a war made upon the Thogarians, received a wound in his arm, of which he died immediately. He was succeeded by his son Mithridates, to whom his exploits gained the surname of Great; for, being fired with a brave emulation of his forefathers, he surpassed their fame by the greatness of his soul. Accordingly, he carried on many wars against his neighbours with signal gallantry, and added many provinces to the Parthian Empire. Not satisfied with this, he often had war with the Scythians; and by the victories he obtained over them revenged the injury his father had received from them. At last, he employed his arms against Ortoadistes, king of the Armenians. WARS WITH ROME [Sidenote: [54-36 B.C.]] After the war of Armenia, Mithridates, king of the Parthians, was banished his kingdom for his cruelty, by the Parthian senate. Orodes his brother, having possessed himself of the vacant throne, besieged Babylon, to which city this fugitive prince had fled; and after a long siege forced the people, by famine, to surrender. Mithridates, relying upon his being so nearly related to Orodes, voluntarily gave himself up to him; but Orodes, considering him rather as an enemy than a brother, commanded him to be killed in his own presence; and after these things carried on a war with the Romans, and cut to pieces their general Crassus, together with his son and all his army. His son Pacorus being sent to pursue the remainder of the Roman war, after he had performed very great actions in Syria was recalled by his father, who was become jealous of him. In his absence, the Parthian army left in Syria was cut off, with its commanders, by Cassius, paymaster to Crassus.
