The Samnite nation, which, at the time of the expulsion of the Tarquins from Rome, had doubtless already been for a considerable period in possession of the hill-country which rises between the Apulian and Campanian plains and commands them both, had hitherto found its further advance impeded on the one side by the Daunians --the power and prosperity of Arpi fall within this period--on the other by the Greeks and Etruscans. But the fall of the Etruscan power towards the end of the third, and the decline of the Greek colonies in the course of the fourth century, made room for them towards the west and south; and now one Samnite host after another marched down to, and even moved across, the south Italian seas. They first made their appearance in the plain adjoining the bay, with which the name of the Campanians has been associated from the beginning of the fourth century; the Etruscans there were suppressed, and the Greeks were confined within narrower bounds; Capua was wrested from the former (330), Cumae from the latter (334). About the same time, perhaps even earlier, the Lucanians appeared in Magna Graecia: at the beginning of the fourth century they were involved in conflict with the people of Terina and Thurii; and a considerable time before 364 they had established themselves in the Greek Laus. About this period their levy amounted to 30,000 infantry and 4000 cavalry. Towards the end of the fourth century mention first occurs of the separate confederacy of the Bruttii,(19) who had detached themselves from the Lucanians--not, like the other Sabellian stocks, as a colony, but through a quarrel --and had become mixed up with many foreign elements. The Greeks of Lower Italy tried to resist the pressure of the barbarians; the league of the Achaean cities was reconstructed in 361; and it was determined that, if any of the allied towns should be assailed by the Lucanians, all should furnish contingents, and that the leaders of contingents which failed to appear should suffer the punishment of death. But even the union of Magna Graecia no longer availed; for the ruler of Syracuse, Dionysius the Elder, made common cause with the Italians against his countrymen. While Dionysius wrested from the fleets of Magna Graecia the mastery of the Italian seas, one Greek city after another was occupied or annihilated by the Italians. In an incredibly short time the circle of flourishing cities was destroyed or laid desolate. Only a few Greek settlements, such as Neapolis, succeeded with difficulty, and more by means of treaties than by force of arms, in preserving at least their existence and their nationality. Tarentum alone remained thoroughly independent and powerful, maintaining its ground in consequence of its more remote position and its preparation for war--the result of its constant conflicts with the Messapians. Even that city, however, had constantly to fight for its existence with the Lucanians, and was compelled to
