A painting from Pompeii depicting a riot at the local amphitheater.
About the same time [59 AD] a trifling beginning led to frightful bloodshed between the inhabitants of Nuceria and Pompeii, at a gladiatorial show exhibited by Livineius Regulus, who had been, as I have related, expelled from the Senate. With the unruly spirit of townsfolk, they began with abusive language of each other; then they took up stones and at last weapons, the advantage resting with the populace of Pompeii, where the show was being exhibited. And so there were brought to Rome a number of the people of Nuceria, with their bodies mutilated by wounds, and many lamented the deaths of children or of parents. The emperor entrusted the trial of the case to the Senate, and the Senate to the consuls, and then again the matter being referred back to the Senators, the inhabitants of Pompeii were forbidden to have any such public gathering for ten years, and all associations they had formed in defiance of the laws were dissolved. Livineius and the others who had excited the disturbance, were punished with exile.
