_Picenum_ consisted of a flat, fertile plain along the Adriatic, and a hilly region, consisting of twisted spurs of the Apennines, in the interior. Poets praised the apples of Picenum, and its olives were among the choicest in Italy. The _Sabine_ territory, at its greatest extension, was 200 miles in length, and reached nearly from sea to sea. It was inhabited by many tribes, probably of common origin. Beside the Sabines proper, were the Sam´nites, the Frenta´ni, and the Marsi, Mar´ruci´ni, Pelig´ni, and Vesti´ni, who formed the League of the Four Cantons. The Sabine country, though rough, was fertile, and its wine and oil chiefly supplied the common people of Rome. =6.= SOUTHERN ITALY included four countries: Luca´nia and Brut´tium on the west, Apulia and Cala´bria on the east. _Lucania_ is a picturesque and fertile country, watered by many rivers. _Bruttium_ is of similar character, and was especially valued in old times for its pine forests, which, from their timber and pitch, yielded an important revenue to the Roman government. Both countries attracted multitudes of Greek colonists, whose cities early rose to a high degree of wealth and civilization. (See Book III, §§ 87, 90.) _Apulia_, unlike any other division of central or southern Italy, consists chiefly of a rich, unbroken plain, from twenty to forty miles in width, gently sloping from the mountains to the sea. In ancient times it maintained great numbers of horses and sheep, the latter of which were famed for the fineness of their wool. When the plain became parched by summer heats, the flocks were driven to the neighboring mountains of Samnium; while, in winter, the Samnite flocks forsook their bleak and snowy heights to find pasturage in the rich meadows of Apulia. The northern portion of Apulia is mountainous, being traversed by two strong spurs of the Apennines, one of which projects into the sea and forms the rocky headland of Mount Garga´nus. _Calabria_,[62] called by the Greeks Iapyg´ia or Messa´pia, occupied the long peninsula which is commonly called the heel of Italy. Its soft limestone soil quickly absorbs moisture, rendering the country arid, and the heats of summer intense. The products of the soil were, however, in ancient times, abundant and of great value. Its oil, wine, and honey were widely celebrated, the wool afforded by its flocks was of the finest quality, and the horses which recruited the Tarentine cavalry were among the most excellent in the world. =7.= Italy possessed three islands of great importance: Sicily, noted for its excellent harbors and inexhaustible soil; Sardin´ia, for its silver mines and harvests of grain; and Cor´sica, for its dense forests of pine and fir. The position as well as the valuable productions of these islands, early tempted the enterprise of both Greeks and Carthaginians; and rivalry in their possession first drew these nations into hostility with each other, and with the ultimately victorious power of Rome.
