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.
