Fires were frequent enough in Rome; during these conflagrations violence and robbery were rampant, particularly so in those sections of the city inhabited by needy half-barbarian peoples, a folk comprising rabble from every part of the world. The fear of servile rebellion was like a nightmare, which had stifled Rome for many years. It was believed that hundreds of thousands of those people were thinking of the times of Spartacus, and merely waiting for a favorable moment to seize arms against their oppressors and Rome. Now the moment had come! Perhaps war and slaughter were raging in the city together with fire. It was possible even that the prætorians had hurled themselves on the city and were slaughtering at command of Cæsar. And that moment the hair rose on Vinicius' head from terror. He recalled all the conversations about burning cities which for some time had been repeated at Cæsar's court with wonderful persistence; well he recalled Cæsar's complaints that he was forced to describe a burning city without having seen an actual fire; his contemptuous answer to Tigellinus, who offered to burn Antium or an artificial wooden city; finally, his complaints against Rome, and the pestilential alleys of the Subura. Yes; truly Cæsar has commanded the burning of the city! Only he could give such a command, as Tigellinus alone could accomplish it. But if Rome is burning at command of Cæsar, who can be sure that the population will not be slaughtered at his command? The monster is capable of just such a deed. Conflagration, a servile revolt, and slaughter! What a horrible chaos, what a letting loose of destructive elements and horrid, universal frenzy! The night had paled long since, the dawn had passed into light, and on all the nearer summits golden, rosy gleams were shining, which might come either from burning Rome or the rising daylight. Vinicius ran to the hill, the summit was reached, and then a terrible sight struck his eyes. All the lower region was covered with smoke, forming, as it were, one gigantic cloud lying close to the earth. In this cloud towns, aqueducts, villas, trees, disappeared; but farther beyond this gray, ghastly plain the city was burning on the hills. The conflagration had not the form of a pillar of fire, as happens when a single building is burning, even when of the greatest size. That was a long belt, rather, shaped like the belt of dawn. Above this belt rose a wave of smoke, in places entirely black, in places looking rose-colored, in places like blood, in places turning in on itself, in some places inflated, in others squeezed and squirming, like a serpent which is unwinding and extending.
