Rome is one of those large cities which are least able to exist upon their own resources, and having no port, and its immediate vicinity being rendered uninhabitable by miasmata, it has attached to it outlying places, and occupies a position similar to that of a spider in the centre of its web. Its gardens, rural retreats, and industrial establishments are all in the hill towns of Tivoli, Frascati (near which on a ridge are the ruins of Tusculum), Marino (near which the confederated nations of Latium held their meetings), Albano (joined by a magnificent viaduct to Ariccia), Velletri (the old city of the Volsci), and Palestrina (more ancient than either Alba Longa or Rome, and occupying the site of a famous temple of Fortune, the pride of ancient Præneste). Its watering-places are Palo, Fiumicino, and Porto d’Anzio, which adjoins the little town of Nettuno, so famous because of the {281} haughty beauty of its women. Its only seaport is Cività Vecchia, a dreary town on the Tyrrhenian Sea, with a magnificent harbour.[93] The ancient harbours to the south of the Tiber are very little resorted to in our day. Terracina, hidden amidst verdure at the foot of white cliffs, is only used by Rome-bound travellers coming by the coast road from the south.[94] Nearly every other town of Latium is built on one or other of the two great roads, of which one leads northward to Florence, whilst the other penetrates the valley of the Sacco towards the south-east, and finally issues upon the campagna of Naples. Viterbo, the “city of nice fountains and pretty girls,” is the principal town in the north. Alatri, on the slope of the Garigliano, and commanded by a superb necropolis enclosed by cyclopean walls, occupies a similar position in the south. In the east, in one of the most charming valleys of Sabina, traversed by the ever-cool waters of the Anio, lies Subiaco, the ancient Sublaqueum, thus named after the three reservoirs constructed by Nero, who used to fish trout in them with a golden net. It was in a holy cave (_sacro specu_) near Subiaco that St. Benedict established his famous monastery, which preceded the still more famous monastery of Monte Casino, and conjointly with that of Lérins, in Provence, became the cradle of monachism in the West.[95] [Illustration: Fig. 102.—CIVITÀ VECCHIA.
