Sometimes he engaged Roman knights to act upon the stage, or to fight as gladiators; but only before the practice was prohibited by a decree of the senate. Thenceforth, the only exhibition he made of that kind, was that of a young man named Lucius, of a good family, who was not quite two feet in height, and weighed only seventeen pounds, but had a stentorian voice. In one of his public spectacles, he brought the hostages of the Parthians, the first ever sent to Rome from that nation, through the middle of the amphitheatre, and placed them in the second tier of seats above him. He used likewise, at times when there were no public entertainments, if any thing was brought to Rome which was uncommon, and might gratify curiosity, to expose it to public view, in any place whatever; as he did a rhinoceros in the Septa, a tiger upon a stage, and a snake fifty cubits lung in the Comitium. It happened in the Circensian games, which he performed in consequence of a vow, that he was taken ill, and obliged to attend the Thensae [185], reclining on a litter. Another time, in the games celebrated for the opening of the theatre of Marcellus, the joints of his curule chair happening to give way, he fell on his back. And in the games exhibited by his (107) grandsons, when the people were in such consternation, by an alarm raised that the theatre was falling, that all his efforts to re-assure them and keep them quiet, failed, he moved from his place, and seated himself in that part of the theatre which was thought to be exposed to most danger.
