In 68 he won a victory over Tigranes and Mithradates, at the river Arsanias; but his legions refused to follow him farther, and he was obliged to lead them into winter quarters in Mesopotamia. The next year his soldiers again mutinied, and he was replaced by Pompey. Returning to Rome, Lucullus spent the rest of his days in retirement, dying about 57. He was very rich, and was famed for the luxurious dinners which he gave. POMPEY AND CRASSUS. The Sullan system stood for nine years, and was then overthrown, as it had been established, by a soldier. It was the fortune of Pompey, a favorite officer of Sulla, to cause the first violation of the laws laid down by his general. GNEIUS POMPEIUS MAGNUS (106-48) led a soldier's life from his boyhood to his death. When a youth of seventeen he fought by his father's side in the civil struggles between Marius and Sulla. He was a partisan of the latter, and connected himself with the cause of the aristocracy. He defeated the followers of Marius in Sicily and Africa, and in 81 was allowed to enjoy a triumph, though still an Eques and not legally qualified. Sulla then greeted him with the surname of Magnus, which he ever afterwards bore. He was then sent to Spain, with what success we have seen in the previous chapter. In 70 Pompey and MARCUS LICINIUS CRASSUS were elected Consuls amid great enthusiasm. Crassus (108-53), the conqueror of Spartacus, had amassed immense wealth by speculation, mining, dealing in slaves, and other methods. Avarice is said to have been his ruling passion, though he gave large sums to the people for political effect. Neither Pompey nor Crassus, according to the laws passed by Sulla, was eligible to the consulship. The former had never been Quaestor, and was only thirty-five years old; the latter was still Praetor, and ought to have waited two years. The work of Sulla was now quickly undone. The Tribunes regained their prerogative, the veto. The control of the criminal courts was transferred again from the Senate to the Equites, and the former body was cleared of its most worthless members, who had been appointed by Sulla. For three years (70-67) after the expiration of his consulship, Pompey remained quietly at Rome. He was then put in charge of an expedition against the Greek pirates. From the earliest times these marauders had been in the habit of depredating on the shores of the Mediterranean. During the civil wars of Rome they had become much bolder, so that the city was compelled to take an active part against them. They had paralyzed the trade of the Mediterranean, and even the coasts of Italy were not safe from their raids. GABINIUS, a Tribune, proposed that Pompey should hold his command for three years; that he should have supreme authority over all Roman magistrates in the provinces throughout the Mediterranean, and over the coasts for fifty miles inland. He was to have fifteen lieutenants, all ex-praetors, two hundred ships, and all the troops he needed.
