Vico Varo and Lucretilis.

The other spots mentioned by Horace as near his farm, are the Chapel of Vacuna, the slopes of Ustica, and the mountain of Lucretilis. The first of these has been placed by the Italian topographers at Rocca Giovane, a village perched on a hill on the west side of the valley about two miles above Cantalupo Bardella. The evidence for this identification is, however, very doubtful.

The Ustica cubans of the poet is commonly with some probability supposed to be La Rustica, which lies on the hill close to Licenza on the eastern side of the valley. Lucretilis is probably a name applied to the whole range of hills connected with Monte Gennaro. Cav. Rosa, however, places it at Monte del Corynaleto just above Rocca Giovane. The name of Fons Bandusiæ has been given to most of the springs in this valley by the enthusiastic admirers of Horace, but it is quite uncertain whether the Fons Bandusiæ was not in Apulia.

(F) THE NORTH-WESTERN DISTRICT.

The principal roads which traversed the Campagna to the north and north-west of Rome are the Nomentana, the Salaria and the Flaminia. These roads offer but little, within the bounds of ancient Latium, which calls for remark.

The Via Nomentana diverged from the Via Salaria at the Collina gate in the Servian walls, and passed through the Aurelian wall at a gate which now stands a little to the south of the modern Porta Pia. The present road follows the line of the ancient Via Nomentana, as may be seen by the ruins of tombs which fringe it beyond S. Agnese. The Chapel of S. Constanza, opposite S. Agnese, is an interesting building of the Constantinian epoch, and the mosaics it contains, including a mixture of Christian and pagan emblems, are very remarkable. The Mons Sacer stands just beyond the bridge over the Anio, and the Villa of Phaon, where Nero ended his life, was at the Vigne Nuove, on a side road which branches off to the right, just beyond the Ponte Nomentano.
