Reforming the calendar · 改革历法
reported-in-source
Suetonius describes regulating the year by the sun, intercalation and the insertion of additional months in the reform year.
Evidence limit: The timeline adopts conventional historical years. It does not silently convert pre-reform calendar days to Julian or Gregorian equivalents.

Turning afterwards his attention to the regulation of the commonwealth, he corrected the calendar, which had for some time become extremely confused, through the unwarrantable liberty which the pontiffs had taken in the article of intercalation. To such a height had this abuse proceeded, that neither the festivals designed for the harvest fell in summer, nor those for the vintage in autumn. He accommodated the year to the course of the sun, ordaining that in future it should consist of three hundred and sixty-five days without any intercalary month; and that every fourth year an intercalary day should be inserted. That the year might thenceforth commence regularly with the calends, or first of January, he inserted two months between November and December; so that the year in which this regulation was made consisted of fifteen months, including the month of intercalation, which, according to the division of time then in use, happened that year.
Edition note
Julius Caesar was assisted by Sosigenes, an Egyptian philosopher, in correcting the calendar. For this purpose he introduced an additional day every fourth year, making February to consist of twenty-nine days instead of twenty-eight, and, of course, the whole year to consist of three hundred and sixty-six days. The fourth year was denominated Bissextile, or leap year, because the sixth day before the calends, or first of March, was reckoned twice. The Julian year was introduced throughout the Roman empire, and continued in general use till the year 1582. But the true correction was not six hours, but five hours, forty-nine minutes; hence the addition was too great by eleven minutes. This small fraction would amount in one hundred years to three-fourths of a day, and in a thousand years to more than seven days. It had, in fact, amounted, since the Julian correction, in 1582, to more than seven days. Pope Gregory XIII., therefore, again reformed the calendar, first bringing forward the year ten days, by reckoning the 5th of October the 15th, and then prescribing the rule which has gradually been adopted throughout Christendom, except in Russia, and the Greek church generally.

The spectacles he exhibited to the people were of various kinds; namely, a combat of gladiators, and stage-plays in the several wards of the city, and in different languages; likewise Circensian games, wrestlers, and the representation of a sea-fight. In the conflict of gladiators presented in the Forum, Furius Leptinus, a man of praetorian family, entered the lists as a combatant, as did also Quintus Calpenus, formerly a senator, and a pleader of causes. The Pyrrhic dance was performed by some youths, who were sons to persons of the first distinction in Asia and Bithynia. In the plays, Decimus Laberius, who had been a Roman knight, acted in his own piece; and being presented on the spot with five hundred thousand sesterces, and a gold ring, he went from the stage, through the orchestra, and resumed his place in the seats allotted for the equestrian order. In the Circensian games, the circus being enlarged at each end, and a canal sunk round it, several of the young nobility drove chariots, drawn, some by four, and others by two horses, and likewise rode races on single horses. The Trojan game was acted by two distinct companies of boys, one differing from the other in age and rank. The hunting of wild beasts was presented for five days successively; and on the last day a battle was fought by five hundred foot, twenty elephants, and thirty horse on each side. To afford room for this engagement, the goals were removed, and in their space two camps were pitched, directly opposite to each other. Wrestlers likewise performed for three days successively, in a stadium provided for the purpose in the Campus Martius. A lake having been dug in the little Codeta, ships of the Tyrian and Egyptian fleets, containing two, three, and four banks of oars, with a number of men on board, afforded an animated representation of a sea-fight. To these various diversions there flocked such crowds of spectators from all parts, that most of the strangers were obliged to lodge in tents erected in the streets, or along the roads near the city. Several in the throng were squeezed to death, amongst whom were two senators.

He filled up the vacancies in the senate, by advancing several plebeians to the rank of patricians, and also increased the number of praetors, aediles, quaestors, and inferior magistrates; restoring, at the same time, such as had been degraded by the censors, or convicted of bribery at elections. The choice of magistrates he so divided with the people, that, excepting only the candidates for the consulship, they nominated one half of them, and he the other. The method which he practised in those cases was, to recommend such persons as he had pitched upon, by bills dispersed through the several tribes to this effect: Caesar the dictator to such a tribe (naming it). I recommend to you (naming likewise the persons), that by the favour of your votes they may attain to the honours for which they sue. He likewise admitted to offices the sons of those who had been proscribed. The trial of causes he restricted to two orders of judges, the equestrian and senatorial; excluding the tribunes of the treasury who had before made a third class. The revised census of the people he ordered to be taken neither in the usual manner or place, but street by street, by the principal inhabitants of the several quarters of the city; and he reduced the number of those who received corn at the public cost, from three hundred and twenty, to a hundred and fifty, thousand. To prevent any tumults on account of the census, he ordered that the praetor should every year fill up by lot the vacancies occasioned by death, from those who were not enrolled for the receipt of corn.
