At times he stopped and rubbed his eyes. Tearing off the edge of his tunic, he covered his nose and mouth with it and ran on. As he approached the river the heat increased terribly. Vinicius, knowing that the fire had begun at the Circus Maximus, thought at first that that heat came from its cinders and from the Forum Boarium and the Velabrum, which, situated near by, must be also in flames. But the heat was growing unendurable. One old man on crutches and fleeing, the last whom Vinicius noticed, cried: "Go not near the bridge of Cestius! The whole island is on fire!" It was, indeed, impossible to be deceived any longer. At the turn toward the Vicus Judæorum the young tribune saw flames amid clouds of smoke. Not only the island was burning, but the Trans-Tiber and the other end of the street on which he ran. The thunder of the flames was more terrible than the roar of wild beasts, and the hour had come now in which he must think of his own safety, for the river of fire was flowing nearer and nearer from the direction of the island, and rolls of smoke covered the alley almost completely. The taper which he carried was quenched from the current of air. Vinicius rushed to the street, and ran at full speed toward the Via Portuensis, whence he had come; the fire seemed to pursue him with burning breath, now surrounding him with fresh clouds of smoke, now covering him with sparks, which fell on his hair, neck, and clothing. The tunic began to smoulder on him in places; he cared not, but ran forward lest he might be stifled from smoke. He had the taste of soot and burning in his mouth; his throat and lungs were as if on fire. The blood rushed to his head, and at moments all things, even the smoke itself, seemed red to him. Then he thought: "This is living fire! Better throw myself upon the ground and quickly perish." The running tortured him more and more. His head, neck, and shoulders were streaming with sweat, which scalded like boiling water. But he ran on as if drunk, staggering from one side of the street to the other. Meanwhile something changed in that monstrous conflagration which had embraced the giant city. Everything which till then had only glimmered, burst forth visibly into one sea of flame; the wind had ceased to bring smoke. That smoke which had collected in the streets was borne away by a mad whirl of heated air. That whirl drove with it millions of sparks, so that Vinicius was running in a fiery cloud, as it were. But he was able to see before him all the better, and in a moment, almost when he was ready to fall, he saw the end of the street. That sight gave him fresh strength. Passing the corner, he found himself in a street which led to the Via Portuensis and the Codetan Field. The sparks ceased to drive him. He understood that if he could run to the Via Portuensis he was safe, even were he to faint on it.
