The Via Flaminia is here bordered for a long distance on the left-hand side by tufa rocks of a reddish hue, whence the district had obtained, in Livy’s time, the name of Saxa Rubra. The Cremera, now the Valca, is one of the streams which enter the Tiber in this district, and beyond it, where the road turns to the left, and, leaving the valley of the Tiber, ascends the hill through a cutting, is the stream and hamlet of Prima Porta. On the right of the road here, and between it and the Tiber, lie the ruins of a large villa, the various terraces of which, raised one above the other, occupy the whole of the top of the hill, and command magnificent views of the Sabine and Æquian highlands. There can be no doubt that these ruins are the remains of the villa of Livia called ad Gallinas, mentioned by Pliny and by Suetonius as situated at the ninth milestone on the Via Flaminia. The style of construction in the walls which remain corresponds to that of the Mausoleum of Augustus in the Campus Martius. The reticulated work has that peculiar irregularity about it which indicates the transition from the opus incertum to the more regularly formed opus reticulatum. Nibby had pointed out this spot in 1837 as one in which a rich harvest might be reaped from excavating, but it was not till 1863 that the splendid Statue of Augustus, now in the Braccio Nuovo of the Vatican with other interesting sculptures, was dug up here.[161] At the same time some rooms were excavated at a depth of ten feet, under the level of the ancient villa. They had apparently been closed at a very early time and filled with earth, in order to erect a building over them. The largest of these was apparently intended as a cool retreat during the summer heats, and the walls are painted with trees and birds, in imitation of a rustic bower. These paintings have attracted great attention as being some of the most ancient now in existence, and also on account of their intrinsic beauty, and the wonderful way in which they have preserved their freshness of colour. The pavement of this painted room was of marble, which was, however, removed when the earth was thrown in at the time of building the rooms above. The legend about this villa connects it with the death of Nero, relating that the laurel bushes and the white fowls, for which the villa had been celebrated since the days of Livia, withered and died out during Nero’s last days. [Sidenote: Veii.] Beyond Prima Porta, to the west, is the site of Veii. This is about twelve miles from Rome, and now bears the name of Isola Farnese. But little remains of the ancient city have been found, but no doubt is now felt by antiquaries that the city occupied the rocky ground between the Cremera and the Fosso de’ due Fossi.
