Throughout the remainder of the few years during which the reign of Caius continued, Seneca, warned in time, withdrew himself into complete obscurity, employing his enforced leisure in that unbroken industry which stored his mind with such encyclopaedic wealth. "None of my days," he says, in describing at a later period the way in which he spent his time, "is passed in complete ease. I claim even a part of the night for my studies. I do not _find leisure_ for sleep, but I _succumb_ to it, and I keep my eyes at their work even when they are wearied and drooping with watchfulness. I have retired, not only from men, but from affairs, and especially from my own. I am doing the work for posterity; I am writing out things which may prove of advantage to them. I am intrusting to writing healthful admonitions--compositions, as it were, of useful medicines." But the days of Caius drew rapidly to an end. His gross and unheard-of insults to Valerius Asiaticus and Cassius Chaereas brought on him condign vengeance. It is an additional proof, if proof were wanting, of the degradation of Imperial Rome, that the deed of retribution was due, not to the people whom he taxed; not to the soldiers, whole regiments of whom he had threatened to decimate; not to the knights, of whom scores had been put to death by his orders; not to the nobles, multitudes of whom had been treated by him with conspicuous infamy; not even to the Senate, which illustrious body he had on all occasions deliberately treated with contumely and hatred,--but to the private revenge of an insulted soldier. The weak thin voice of Cassius Chaereas, tribune of the praetorian cohort, had marked him out for the coarse and calumnious banter of the imperial buffoon; and he determined to avenge himself, and at the same time rid the world of a monster. He engaged several accomplices in the conspiracy, which was nearly frustrated by their want of resolution. For four whole days they hesitated, while day after day, Caius presided in person at the bloody games of the amphitheatre. On the fifth day (Jan. 24, A.D. 41), feeling unwell after one of his gluttonous suppers, he was indisposed to return to the shows, but at last rose to do so at the solicitation of his attendants. A vaulted corridor led from the palace to the circus, and in that corridor Caius met a body of noble Asiatic boys, who were to dance a Pyrrhic dance and sing a laudatory ode upon the stage. Caius wished them at once to practice a rehearsal in his presence, but their leader excused himself on the grounds of hoarseness. At this moment Chaereas asked him for the watchword of the night. He gave the watchword, "Jupiter." "Receive him in his wrath!" exclaimed Chaereas, striking him on the throat, while almost at the same moment the blow of Sabinus cleft the tyrant's jaw, and brought him to his knee. He crouched his limbs together to screen himself from further blows, screaming aloud, "I live! I live!" The bearers of his litter
