[-25-] While Caesar was thus engaged he was also enacting many laws, passing over most of which I shall mention only those most deserving attention. The courts he entrusted to the senators and the knights alone so that the purest element of the population, so far as was possible, might always preside: formerly some of the common people had also joined with them in rendering decisions. The expenditures, moreover, of men of means which had been rendered enormous by their licentiousness he not only controlled by law but put a strong check upon them by practical measures. There was, on account of the numbers of warriors that had perished, a dangerous scarcity of population, as was proved both from the censuses (which he attended to, among other things, as if he were censor) and from actual observation, consequently he offered prizes for large families of children. Again, because he himself as a result of ruling the Gauls many years in succession had been attracted into a desire for dominion and had by it increased the equipment of his force, he limited by law the term of ex-praetors to one year, and that of ex-consuls to two consecutive years, and enacted in general that no one should be allowed to hold any office for a longer time. [-26-] After the passage of these laws he also established in their present fashion the days of the year (which were not definitely settled among the people, since even at that time they regulated their months according to the movements of the moon) by adding sixty-seven days, all that were necessary to bring the year out even. In the past some have declared that even more were interpolated, but the truth is as I have stated it. He got this improvement from his stay in Alexandria, save in so far as those people calculate their months as of thirty days each, afterward annexing the five days to the entire year as a whole, whereas Caesar distributed among seven months these five along with two other days that he took away from one month.[93] The one day, however, which is made up of four parts Caesar introduced every fourth year, so as to have the annual seasons no longer differ at all except in the slightest degree. In fourteen hundred and sixty-one years there is need of only one (additional) intercalary day.[94]
