The influence of Cæsar was now becoming very conspicuous. His military career in Gaul, his generosity, and the universality of his talents, gave him at length a pre-eminence over Pompey in the public estimation. Pompey and Crassus had entered into the consulship with little observance of constitutional forms; and, with as little deference to the senate, had caused provinces to be assigned to them for five years. Spain and Africa to Pompey. Syria and the fatal Parthian war to Crassus. This triumvirate had now almost the whole Roman military force at their command. It was in the spring of the next year, that Cicero at his Cuman villa, began his famous work on government. He was now advancing into his fifty-fourth year, and it appears that he had completed his work before he entered upon his command in Cilicia. His military career was distinguished by great activity and judgment. He was saluted emperor by the army upon one of his military successes, and returned gladly to Rome at the end of the year. During the remainder of his eventful life, he appears to have found comfort only in the cultivation of philosophy and letters. The corruption of the Romans, the ruin of the republic, the death of his beloved daughter, and his separation from the wife he had lived with thirty years, embittered his days. He was too conspicuous a man not to be affected by all the political changes which took place. Crassus perished in the Parthian war; and Cæsar, as soon as he felt himself strong enough, crossed the Rubicon, which was the limit of his military command, and marched upon Rome, from which Pompey and the senate ingloriously fled. Cicero at length felt himself also constrained to follow the fortunes of Pompey, because he believed the dignity of the Roman name was alone to be found under his banners. And when the battle of Pharsalia left Cæsar sole master of the Roman world, he submitted to Cæsar, because there was no other government to submit to. But he rejoiced in his death, of which he was a spectator, and to the last, gave all the aid in his power to the patriots who sought to raise the liberties of his country. In his latter days, he showed an invincible spirit, defying the profligate Anthony in the plenitude of his power. And when the assassins of the second and more bloody triumvirate surprised him, he ordered his servants to set down the litter in which they were carrying him, and forbade them to defend him. Then undauntedly stretching out his neck, he bade his executioners do their pleasure; happy to escape from so much misery, to the immortality he had always believed in. This occurred when he was just entering his sixty-fourth-year.
