Among the hills of the ancient Hernici round the source of the Sacco are—PALESTRINA, described in a separate article. Paliano, situated on an isolated rocky hill fortified with towers and bastions, and approached only by means of a drawbridge : population, 3700. Cari„ picturesquely situated on a rock of tufa above a torrent-feeder of the Sacco, over which a fine bridge of seven arches is thrown : population, 2000. Genezzano, built on a steep hill 4 miles E. from Cavi, is famous for its the Madonna, on whose feast the peasantry of all this part of the province assemble in the town : population 2500; on the summit of the hill is a baronial castle of the Cotentin, separated from the town by a drawbridge. Olcvano, a medimval town situated in the midst of the most romantic scenery, a few miles north of Genezzano, has about 3000 inhabitants. Zagarolo, a small town of 3600 inhabitants, situated on a long ridge that projects into the plain about 6 miles W. from Palestrina, has some handsome churches and a baronial castle, which formerly belonged to the Colonna. Castiglione, a small place west of Zagarolo, stands on the site of the citadel of ancient Gabii, of which there are still some remains. The Lake of (MU, which occupied an ancient crater, and is not mentioned till the 5th century, has been recently drained by Prince Borghese. Near the junction of the Osa with the Toveroue, a little north of Castiglione, stood Collatia, the scene of the death of Lucretia, the wife of Collatinus.
About 12 miles E. from Rome, situated on one of the lower eminences of the Alban Hills, is Frascati, surrounded by magnificent villas. [Feas Cart] North-east of Frascati is the ruined village of Colonna, which gave title to the historical family of the Colonna, and occupies tho site of the ancient Labicum. South of Frascati, on an isolated bill at the base of Monte Cavi, the ancient Moue Albanus, is Marino, which occupies the site of the ancient Caeirirecenium, and has about 5100 inhabitants; it is a well-built town with some interesting churches, which are adorned with fine pictures. Between the hill on which Marino stands and the ridge of Alba Longa is a deep wooded glen, called Farce di Colonna, in which the ancient Latine held their general assemblies. Tho stream called by Livy, Aqua Ferentina, still traverses it, and may bo traced to its source at the base of a mass of tufa. Near Marino also is Grotta Ferrata, a small village celebrated for its Basilian monastery, the chapel of which is decorated with magnificent frescoes by Domenichino. The region of the Alban Hills, the Alban Lake, the town of Albano, kke., are noticed under ALBA LOICOA. Separated by a deep ravine from Albano is L'Ariccia, a small place of 1400 inhabit ants, which occupies tho eite of the citadel of the ancient Arida, ruins of which are spread about the neighbourhood. The region of the Alban Hills abounds iu evidences of ancient volcanic action ; the hill elopes are in many parts covered with vineyards. From L'Ariccia is
seen beyond the broad crater of Vallericcia the hill of Monte Giove, famous as the site of Corioli ; and on another hill to the south-east the village of Cirita Leckie, the site of the ancient Lanuvium. East of L'Ariccia is the village of Nerni and the beautiful lake of the same name, the ancient Lucas Nensorentris, which occupies an extinct crater, and is 5 miles in circumfetence. Near the south shore of the lake is denzarso, a town of 4700 inhabitants, celebrated for its flower-mosaics on the octave of the feast of Corpus Christi The Appian Way between L'Ariecia and Genzano is carried across the crater of Vallericcia by a magnificent causeway.
The Campagna to the south-east of Ostia, which forms the subject of a separate article [Osrle], is covered near the sea with pine planta tions and with the great Laureotine forest, which skirts the Mediter. ranean for above 50 miles, with a breadth of about 3 miles from the coast, and abounds with buffaloes, wild boars, and wolves. This region, once dotted with cities, is now all but deserted on account of the malaria. Two miles from Ostia is Cased Pusan, a castellated mansion of the Chigi family, built on the site of Pliny's Laurentine Villa. Farther south, among gigantic groves of stone-pine, ilex, laurel, end wild olive, is Torre di Paterno, a solitary brick-tower, built about half a mile from the sea, among the ruins of an imperial villa. About a mile inland from Torre di Paterno is the site of Latsrentmes. The ancient Lanrentine Way still leads from this region to Rome, but the polygonal blocks with which it is paved have in places been displaced by the roots of the trees which have encroached upon it, and rendered it Impassable for carriages. Pratica, a small hamlet on a strip of table-land, separated from the plain by deep glens, except at one point, marks the site of the ancient Latinism. The Borghese family have a large mansion here, the tower of which commands a fine prospect of the coast, the plain of the Campagna, the Alban Hills, the Ciminian Wood, and the domes and palaces of Rome. Pratica is 18 miles south-southeast from Rome. A few miles south-east of Pratica is the small hamlet and castle of Arica, which marks the site of the ancient Ardea, the city of Turnus. A great castellated mansion of the Ceaarini occupies the site of the citadel. At the extreme south point of the coast are the towns of Porto d'Aazo, on the site of the ancient Asrrrnm, which is noticed in a separate article : and Nettaao, about a mile south of the preceding, which is the largest town now on the coast of Latium, although the population hardly exceeds 1000. The whole coast hereabouts is covered with ruins of Roman villas. The town contains remains of a temple of Neptune, and also an old fortress, now tenanted by the coast-guard. All this part of the coast belongs to the princely house of Borgheee. The malaria and swarms of mosquitos render it uninhabitable in the summer and autumn.
