Caesar now proceeded to correct the various evils which had crept into the state, and to obtain the enactment of several laws suitable to the altered condition of the commonwealth. He attempted, by severe sumptuary laws, to restrain the extravagance which pervaded all classes of society. But the most important of his changes this year (B.C. 40) was the reformation of the Calendar, which was a real benefit to his country and the civilized world, and which he accomplished in his character as Pontifex Maximus. The regulation of the Roman calendar had always been intrusted to the College of Pontiffs, who had been accustomed to lengthen or shorten the year at their pleasure for political purposes; and the confusion had at length become so great that the Roman year was three months behind the real time. To remedy this serious evil, Caesar added 90 days to the current year, and thus made it consist of 445 days; and he guarded against a repetition of similar errors for the future by adapting the year to the sun's course. In the midst of these labors Caesar was interrupted by intelligence of a formidable insurrection which had broken out in Spain, where the remains of the Pompeian party had again collected a large army under the command of Pompey's sons, Cneius and Sextus. Caesar set out for Spain at the end of B.C. 46. With his usual activity he arrived at Obulco, near Corduba, in 27 days from the time of his leaving Rome. He found the enemy able to offer stronger opposition than he had anticipated; but he brought the war to a close by the battle of Munda, on the 17th of March, B.C. 46, in which he entirely defeated the enemy. It was, however, a hard-fought battle: Caesar's troops were at first driven back, and were only rallied by their general's exposing his own person, like a common soldier, in the front line of the battle. Cn. Pompeius was killed shortly afterward, but Sextus made good his escape. The settlement of the affairs in Spain detained Caesar in the province some months longer, and he consequently did not reach Rome till September. At the beginning of October he entered the city in triumph on account of his victories in Spain, although the victory had been gained over Roman citizens. The Senate received him with the most servile flattery. They had in his absence voted a public thanksgiving of fifty days, and they now vied with each other in paying him every kind of adulation and homage. He was to wear, on all public occasions, the triumphal robe; he was to receive the title of "Father of his Country;" statues of him were to be placed in all the temples; his portrait was to be struck on coins; the month of Quintilis was to receive the name of Julius in his honor, and he was to be raised to a rank among the gods. But there were still more important decrees than these, which were intended to legalize his power, and confer upon him the whole government of the Roman world. He received the title of
