Though his health was very infirm during the former part of his life, yet, after he became emperor, he enjoyed a good state of health, except only that he was subject to a pain of the stomach. In a fit of this complaint, he said he had thoughts of killing himself.

He gave entertainments as frequent as they were splendid, and generally when there was such ample room, that very often six hundred guests sat down together. At a feast he gave on the banks of the canal for draining the Fucine Lake, he narrowly escaped being drowned, the water at its discharge rushing out with such violence, that it overflowed the conduit. At supper he had always his own children, with those of several of the nobility, who, according to an ancient custom, sat at the feet of the couches. One of his guests having been suspected of purloining a golden cup, he invited him again the next day, but served him. with a porcelain jug. It is said, too, that he intended to publish an edict, "allowing to all people the liberty of giving vent at table to any distension occasioned by flatulence," upon hearing of a person whose modesty, when under restraint, had nearly cost him his life.

He was always ready to eat and drink at any time or in any place. One day, as he was hearing causes in the forum of Augustus, he smelt the dinner which was preparing for the Salii, The Salii, the priests of Mars, twelve in number, were instituted by Numa. Their dress was an embroidered tunic, bound with a girdle ornamented with brass. They wore on their head a conical cap, of a considerable height; carried a sword by their side; in their right hand a spear or rod, and in their left, one of the Ancilia, or shields of Mars. On solemn occasions, they used to go to the Capitol, through the forum and other public parts of the city, dancing and singing sacred songs, said to have been composed by Numa; which, in the time of Horace, could hardly be understood by any one, even the priests themselves. The most solemn procession of the Salii was on the first of March, in commemoration of the time when the sacred shield was believed to have fallen from heaven, in the reign of Numa. After their procession, they had a splendid entertainment, the luxury of which was proverbial. in the temple of Mars adjoining, whereupon he quitted the tribunal, and went to partake of the feast with the priests. He scarcely ever left the table until he had thoroughly crammed himself and drank to intoxication; and then he would immediately fall asleep, lying upon his back with his'mouth open. While in this condition, a feather was put down his throat, to make him throw up the contents of his stomach. Upon composing himself to rest, his sleep was short, and he usually awoke before midnight; but he would sometimes sleep in the daytime, and that, even, when he was upon the tribunal; so that the advocates often found it difficult to wake him, though they raised their voices for that purpose. He set no bounds to his libidinous intercourse with women, but never betrayed any unnatural desires for the other sex. He was fond of gaming, and published a book upon the subject. He even used to play as he rode in his chariot, having the tables so fitted, that the game was not disturbed by the motion of the carriage.

His cruel and sanguinary disposition was exhibited upon great as well as trifling occasions. When any person was to be put to the torture, or criminal punished for parricide, he was impatient for the execution, and would have it performed in his own presence. When he was at Tibur, being desirous of seeing an example of the old way of putting malefactors to death, some were immediately bound to a stake for the purpose; but there being no executioner to be had at the place, he sent for one from Rome, and waited for his coming until night. In any exhibition of gladiators, presented either by himself or others, if any of the combatants chanced to fall, he ordered them to be butchered, especially the Retiaii, that he might see their faces in the agonies of death. Two gladiators happening to kill each other, he immediately ordered some little knives to be made of their swords for his own use. He took great pleasure in seeing men engage with wild beasts, and the combatants who appeared on the stage at noon. He woul I therefore come to the theatre by break of day, and at noon, dismissing the people to dinner, continued sitting himself; and besides those who were devoted to that sanguinary fate, he would match others with the beasts, upon slight or sudden occasions; as, for instance, the carpenters and their assistants, and people of that sort, if a machine, or any piece of work in which they had been employed about the theatre did not answer the purpose for which it had been intended. To this desperate kind of encounter he forced one of his nomenclators, even encumbered as he was by wearing the toga.

But the characteristics most predominant in him were fear and distrust. In the beginning of his reign, though he much affected a modest and humble appearance, as has been already observed, yet he durst not venture himself at an entertainment without being attended by a guard of spearmen, and made soldiers wait upon him at table instead of servants. He never visited a sick person, until the chamber had been first searched, and the bed and bedding thoroughly examined. At other times, all persons who came to pay their court to him were strictly searched by officers appointed for that purpose; nor was it until after a long time, and with much difficulty, that he was prevailed upon to excuse women, boys, and girls from such rude handling, or suffer their attendants or writing-masters to retain their cases for pens and styles. When Camillus formed his plot against him, not doubting but his timidity might be worked upon without a war, he wrote to him a scurrilous, petulant, and threatening letter, desiring him to resign the government, and betake himself to a life of privacy. Upon receiving this requisition, he had some thoughts of complying with it, and summoned together the principal men of, the city, to consult with them on the subject.
