10. Now as the beginning of each year varies, one commencing at the sixth hour of the day, another at the same hour of the night, to prevent the calculation from throwing all science into confusion by its perplexing diversity, and the months of autumn from sometimes being found to come in the spring, it has been settled that those six hours which in a period of four years amount to twenty-four shall be put together so as to make one day and night.
11. And after much consideration it has been so arranged with the concurrence of many learned men, that thus the revolutions of the year may come to one regular end, removed from all vagueness and uncertainty, so that the theory of the heavens may not be clouded by any error, and that the months may retain their appointed position.
12. Before their dominions had reached any wide extent, the Romans were for a long time ignorant of this fact, and having been for many years involved in obscure difficulties, they were in deeper darkness and error than ever, when they gave the priests the power of intercalating, which they, in profligate subservience to the interests of the farmers of the revenue, or people engaged in lawsuits, effected by making additions or subtractions at their own pleasure.
13. And from this mode of proceeding many other expedients were adopted, all of which were fallacious, and which I think it superfluous now to enumerate. But when they were given up, Octavianus Augustus, in imitation of the Greeks, corrected these disorderly arrangements and put an end to these fluctuations, after great deliberation fixing the duration of the year at twelve months and six hours, during which the sun with its perpetual movement runs through the whole twelve signs, and concludes the period of a whole year.
14. This rule of the bissextile year, Rome, which is destined to endure to the end of time, established with the aid of the heavenly Deity. Now let us return to our history.
II.
§ 1. When this day, so little fit in the opinion of many for beginning any great affair, had passed, at the approach of evening, by the advice of the prefect Sallust, an order was issued by general consent, and with the penalty of death attached to any neglect of it, that no one of higher authority, or suspected of aiming at any objects of ambition, should appear in public the next morning.
2. And when, while the numbers who allowed their own empty wishes to torment them were weary of the slowness of time, the night ended at last, and daylight appeared, the soldiers were all assembled in one body, and Valentinian advanced into the open space, and mounting a tribunal of some height which had been erected on purpose, he was declared ruler of the empire as a man of due wisdom by this assembly, bearing the likeness of a comitia, with the unanimous acclamations of all present.
3. Presently he was clothed with the imperial robe, and crowned, and saluted as Augustus with all the delight which the pleasure of this novelty could engender; and then he began to harangue the multitude in a premeditated speech. But as he put forth his arm to speak more freely, a great murmur arose, the centuries and maniples beginning to raise an uproar, and the whole mass of the cohorts presently urging that a second emperor should be at once elected.
4. And though some people fancied that this cry was raised by a few corrupt men in order to gain the favour of those who had been passed over, it appeared that that was a mistake, for the cry that was raised did not resemble a purchased clamour, but rather the unanimous voice of the whole multitude all animated with the same wish, because recent examples had taught them to fear the instability of this high fortune. Presently the murmurs of the furious and uproarious army appeared likely to give rise to a complete tumult, and men began to fear that the audacity of the soldiers might break out into some atrocious act.
