He assumed the sovereigntyPrinceps, principatus, are the terms gencrally used by Suetonius to describe the supreme authority vested in the Caesars, as before at the beginning of chapter xxiv., distinguished from any terms which conveyed an idea of kingly power, the forms of the republic, as we have lately seen, still subsisting. by slow degrees, and exercised it for a long time with great variety of conduct, though generally with a due regard to the public good. At first he only interposed to prevent ill management. Accordingly, he rescinded some decrees of the senate; and when the magistrates sat for the administration of justice, he frequently offered his service as assessor, either taking his place promiscuously amongst them, or seating himself in a corner of the tribunal. If a rumour prevailed, that any person under prosecution was likely to be acquitted by his interest, he would suddenly make his appearance, and from the floor of the court, or the praetor's bench, remind the judges of the laws, and of their oaths, and the nature of the charge brought before them. He likewise took upon himself the correction of public morals, where they tended to decay, either through neglect, or evil custom.

He reduced the expense of the plays and public spectacles, by diminishing the allowances to actors, and curtailing the number of gladiators. He made grievous complaints to the senate, that the price of Corinthian vessels was become enormous, and that three mullets had been sold for thirty thousand sesterces: upon which he proposed that a new sumptuary law should be enacted; that the butchers and other dealers in viands should be subject to an assize, fixed by the senate yearly; and the aediles commissioned to restrain eating-houses and taverns, so far as not even to permit the sale of any kind of pastry. And to encourage frugality in the public by his own example, he would often, at his solemn feasts, have at his tables victuals which had been served up the day before, and were partly eaten, and half a boar, affirming, It has all the same good bits that the whole had." He published an edict against the practice of people's kissing each other when they met; and would not allow new year's gifts Strenas; the French étrennes. to be presented after the calends [the first] of January was passed. He had been in the habit of returning these offerings four-fold, and making them with his own hand; but being annoyed by the continual interruption to which he was exposed during the whole month, by those who had not the opportunity of attending him on the festival, he returned none after that day.
