After a brief struggle known as the Alexandrine War, which closed in March, 47, Cæsar placed the queen and her brother on the throne. It was at this time that the great Library and Museum at Alexandria were destroyed by fire. Four hundred thousand volumes were said to have been burned. The next month Cæsar was called from Egypt to Pontus, where a son of Mithridates was in arms, and, after a campaign of five days, he gained a decisive victory at a place called Zela, boastfully announcing his success to the senate in three short words: "_Veni, vidi, vici_" (I came, I saw, I overcame). In September, Cæsar was again in Rome, where he remained only three months, arranging affairs. There were fears lest he should make a proscription, but he proceeded to no such extremity, exercising his characteristic clemency towards those who had been opposed to him. A revolt occurred at this time among the soldiers at Capua, and they marched to Rome, but Cæsar cowed them by a display of haughty coolness. The remnant of the adherents of Pompey gathered together and went to Africa, whither Cæsar followed, and after a short campaign defeated them on the field of Thapsus, April 6, 46. They were commanded by Scipio, father-in-law of Pompey, and by Cato, who had accepted the position after it had been declined by Cicero, his superior in rank. After the defeat of Thapsus Cato retreated to Utica, where he deliberately put an end to his life after occupying several hours in reading Plato's _Phædo_, a dialogue on the immortality of the soul. From the place of his death he is known in history as Cato of Utica. When the news of this final victory reached Rome Cæsar was appointed dictator for ten years, and a thanksgiving lasting forty days was decreed. He was also endowed with a newly created office-that of Overseer of Public Morals (_Præfectus Morum_). Temples and statues were dedicated to his honor; a golden chair was assigned for his use when he sat in the senate; the month Quintilis was renamed after him Julius (July); and other unheard of honors were thrust upon him by a servile senate. He was also called the Father of his Country (a title that had been before borne by Camillus and Cicero), and four triumphs were celebrated for him. On his own part, Cæsar feasted the people at twenty-two thousand tables, and caused combats of wild animals and gladiators to be celebrated in the arenas beneath awnings of the richest silks.
