But all human efforts, all the lavish gifts of the emperor, and the propitiations of the gods, did not banish the sinister belief that the conflagration was the result of an order. Consequently, to get rid of the report, Nero fastened the guilt and inflicted the most exquisite tortures on a class hated for their abominations, called Christians by the populace. Christus, from whom the name had its origin, suffered the extreme penalty during the reign of Tiberius at the hands of one of our procurators, Pontius Pilatus, and a most mischievous superstition, thus checked for the moment, again broke out not only in Judea, the first source of the evil, but even in Rome, where all things hideous and shameful from every part of the world find their centre and become popular. Accordingly, an arrest was first made of all who pleaded guilty; then, upon their information, an immense multitude was convicted, not so much of the crime of firing the city as of hatred against mankind. Mockery of every sort was added to their deaths. Covered with the skins of beasts, they were torn by dogs and perished, or were nailed to crosses, or were doomed to the flames and burnt, to serve as a nightly illumination when daylight had expired. Nero offered his gardens for the spectacle, and was exhibiting a show in the circus while he mingled with the people in the dress of a charioteer or stood aloft on a car. Hence, even for criminals who deserved extreme and exemplary punishment, there arose a feeling of compassion; for it was not, as it seemed, for the public good but rather to glut the cruelty of one man that they were being destroyed.
Agricola did not see the senate-house besieged, or the senate hemmed in by armed men, or so many of Rome's noblest ladies exiles and fugitives. Carus Metius had as yet the distinction of but one victory, and the noisy counsels of Messalinus were not heard beyond the walls of Alba, and Massa Baebius was then answering for his life. It was not long before our hands dragged Helvidius to prison, before we gazed on the dying looks of Manricus and Rusticus, before we were steeped in Senecio's innocent blood. Even Nero turned his eyes away, and did not gaze upon the atrocities which he ordered; with Domitian it was the chief part of our miseries to see and to be seen, to know that our sighs were being recorded, to have, ever ready to note the pallid looks of so many faces, that savage countenance reddened with the hue with which he defied shame.
