We now come to the fourth region, which includes the most valiant probably of all the nations of Italy. Upon the coast, in the territory of the Frentani[1726], after the river Tifernus, we find the river Trinium[1727], with a good harbour at its mouth, the towns of Histonium[1728], Buca[1729], and Ortona, and the river Aternus[1730]. In the interior are the Anxani surnamed Frentani, the Higher and Lower Carentini[1731], and the Lanuenses; in the territory of the Marrucini, the Teatini[1732]; in that of the Peligni, the Corfinienses[1733], the Superæquani[1734], and the Sulmonenses[1735]; in that of the Marsi, the Anxantini[1736], the Atinates[1737], the Fucentes[1738], the Lucenses[1739], and the Marruvini[1740]; in that of the Albenses, the town of Alba on Lake Fucinus; in that of the Æquiculani, the Cliternini[1741], and the Carseolani[1742]; in that of the Vestini, the Angulani[1743], the Pinnenses, and the Peltuinates, adjoining to whom are the Aufinates[1744] Cismontani; in that of the Samnites, who have been called Sabelli[1745], and whom the Greeks have called Saunitæ, the colony of old Bovianum[1746], and that of the Undecumani, the Aufidenates[1747], the Esernini[1748], the Fagifulani, the Ficolenses[1749], the Sæpinates[1750], and the Tereventinates; in that of the Sabini, the Amiternini[1751], the Curenses[1752], Forum Decî[1753], Forum Novum, the Fidenates, the Interamnates[1754], the Nursini[1755], the Nomentani[1756], the Reatini[1757], the Trebulani, both those called Mutusci[1758] and those called Suffenates[1759], the Tiburtes, and the Tarinates. In these districts, the Comini[1760], the Tadiates, the Cædici, and the Alfaterni, tribes of the Æquiculi, have disappeared. From Gellianus we learn that Archippe[1761], a town of the Marsi, built by Marsyas, a chieftain of the Lydians, has been swallowed up by Lake Fucinus, and Valerianus informs us that the town of the Viticini in Picenum was destroyed by the Romans. The Sabini (called, according to some writers, from their attention to religious[1762] observances and the worship of the gods, Sevini) dwell on the dew-clad hills in the vicinity of the Lakes of the Velinus[1763]. The Nar, with its sulphureous waters, exhausts these lakes, and, descending from Mount Fiscellus[1764], unites with them near the groves of Vacuna[1765] and Reate, and then directs its course towards the Tiber, into which it discharges itself. Again, in another direction, the Anio[1766], taking its rise in the mountain of the Trebani, carries into the Tiber the waters of three lakes remarkable for their picturesque beauty, and to which Sublaqueum[1767] is indebted for its name. In the territory of Reate is the Lake of Cutiliæ[1768], in which there is a floating island, and which, according to M. Varro, is the navel or central point of Italy. Below the Sabine territory lies that of Latium, on one side Picenum, and behind it Umbria, while the range of the Apennines flanks it on either side.
