3. PICENUM extended along the Adriatic from the mouth of the AEsis to that of the Matrinus and inland as far as the central ridge of the Apennines. It was bounded on the north by Umbria, on the south by the Vestini, and on the west by Umbria and the Sabini. Its inhabitants, the Picentes, were a Sabine race, as is mentioned below. 4. The SABINI inhabited the rugged mountain-country in the central chain of the Apennines, lying between Etruria, Umbria, Picenum, Latium, and the country of the Marsi and Vestini. They were one of the most ancient races of Italy, and the progenitors of the far more numerous tribes which, under the names of Picentes, Peligni, and Samnites, spread themselves to the east and south. Modern writers have given the general name of _Sabellians_ to all these tribes. The Sabines, like most other mountaineers, were brave, hardy, and frugal; and even the Romans looked up to them with admiration on account of their proverbial honesty and temperance. 5. The MARSI, PELIGNI, VESTINI, and MARRUCINI inhabited the valleys of the central Apennines, and were closely connected, being probably all of Sabine origin. The MARSI dwelt inland around the basin of the Lake Fucinus, which is about thirty miles in circumference, and the only one of any extent in the central Apennines. The PELIGNI also occupied an inland district east of the MARSI. The VESTINI dwelt east of the Sabines, and possessed on the coast of the Adriatic a narrow space between the mouth of the Matrinus and that of the Aternus, a distance of about six miles. The MARRUCINI inhabited a narrow strip of country on the Adriatic, east of the Peligni, and were bounded on the north by the Vestini and on the south by the Frentani. 6. The FRENTANI dwelt upon the coast of the Adriatic from the frontiers of the Marrucini to those of Apulia. They were bounded on the west by the Samnites, from whom they were originally descended, but they appear in Roman history as an independent people.
