But reverses were at hand. During the existence of the political combination of Pompey, Caesar, and Crassus, known as the first triumvirate, P. Clodius, an enemy of Cicero's, proposed a law banishing "any one who had put Roman citizens to death without trial." This was aimed at Cicero on account of his share in the Catiline affair, and in March, 58 B. C., he left Rome. The same day a law was passed by which he was banished by name, and his property was plundered and destroyed, a temple to Liberty being erected on the site of his house in the city. During his exile Cicero's manliness to some extent deserted him. He drifted from place to place, seeking the protection of officials against assassination, writing letters urging his supporters to agitate for his recall, sometimes accusing them of lukewarmness and even treachery, bemoaning the ingratitude of his country or regretting the course of action that had led to his outlawry, and suffering from extreme depression over his separation from his wife and children and the wreck of his political ambitions. Finally in August, 57 B. C., the decree for his restoration was passed, and he returned to Rome the next month, being received with immense popular enthusiasm. During the next few years the renewal of the understanding among the triumvirs shut Cicero out from any leading part in politics, and he resumed his activity in the law-courts, his most important case being, perhaps, the defence of Milo for the murder of Clodius, Cicero's most troublesome enemy. This oration, in the revised form in which it has come down to us, is ranked as among the finest specimens of the art of the orator, though in its original form it failed to secure Milo's acquittal. Meantime, Cicero was also devoting much time to literary composition, and his letters show great dejection over the political situation, and a somewhat wavering attitude towards the various parties in the state. In 55 B. C. he went to Cilicia in Asia Minor as proconsul, an office which he administered with efficiency and integrity in civil affairs and with success in military. He returned to Italy in the end of the following year, and he was publicly thanked by the senate for his services, but disappointed in his hopes for a triumph. The war for supremacy between Caesar and Pompey which had for some time been gradually growing more certain, broke out in 49 B.C., when Caesar led his army across the Rubicon, and Cicero after much irresolution threw in his lot with Pompey, who was overthrown the next year in the battle of Pharsalus and later murdered in Egypt. Cicero returned to Italy, where Caesar treated him magnanimously, and for some time he devoted himself to philosophical and rhetorical writing. In 46 B.C. he divorced his wife Terentia, to whom he had been married for thirty years and married the young and wealthy Publilia in order to relieve himself from financial difficulties; but her also he shortly divorced.
