The _Subura_ is still called by the same name. Nardini is quite mistaken in his assertion, that the ancient Subura was situated in a different locality, near the Lateran; no man in his senses can admit this, for it is opposed to all our evidence. We even have the express testimony of Varro, that its site is identical with that of the present Subura, that is, in the plain north of the Esquiliae, whence it had the advantage of being completely built on both sides. In it stood the house of Caesar, and in the times of the republic the aristocracy generally lived there and in the Carinae on the Esquiline. Afterwards, in the time of emperors, a change took place in this respect, and every one removed to the new quarters, whence, in the days of Juvenal and Martial, the Subura was inhabited only by the lowest classes; at present, too, it is the abode of poverty. The _Carinae_ were a quarter rather than a single street, in the district of S. Pietro in Vincola. After the great fire, Nero built a palace (not the golden house) there; and not far from it was the palace of Titus and the thermae of Trajan. The Quirinal had no remarkable buildings; at a later period Aurelian erected there the temple of the Sun, the most gigantic building in all Rome, of which vast ruins still exist in the garden of the Colonna family. At that time there was a taste for everything gigantic, because architects were no longer able to produce the beautiful. The _Viminal_, too, contained nothing worth noticing. The Carinae, as I have already remarked, were on the _Esquiline_. Within the walls of Servius Tullius, I know of no particularly remarkable edifice belonging to the early period, though it contained a large number of small temples. The same must be said of the _Caelius_ in its narrower sense; only one arch still exists there; in the middle ages it contained many buildings. On the rugged side of the _Aventine_, towards the river, stood the temple of Diana, which, according to tradition, Servius Tullius had built as a point of union for the Romans and Latins, and in which the table containing the ancient treaty was preserved. On the same hill there existed the thermae of Decius and a number of other buildings. I have already observed, that the Porta Trigemina was on the Aventine towards the river. On the side of the Palatine towards the Aventine there was a flight of marble steps, called the _Scala Caci_; one tradition assigned it to the Palatine, and another to the Aventine, a discrepancy which probably arose from the opposition between the inhabitants of the two hills.
