The Adriatic commerce carried on by Corinth and Corcyra was shared by the most easterly mercantile city of Magna Graecia, the Doric Tarentum, which by the possession of Hydrus (Otranto) had the command, on the Italian side, of the entrance of the Adriatic.

Since, with the exception of the ports at the mouth of the Po, there were in those times no emporia worthy of mention along the whole east coast--the rise of Ancona belongs to a far later period, and later still the rise of Brundisium--it may well be conceived that the mariners of Epidamnus and Apollonia frequently discharged their cargoes at Tarentum.

The Tarentines had also much intercourse with Apulia by land; all the Greek civilization to be met with in the south-east of Italy owed its existence to them.
That civilization, however, was during the present period only in its infancy; it was not until a later epoch that the Hellenism of Apulia was developed.
Relations of the Western Italians to the Greeks It cannot be doubted, on the other hand, that the west coast of Italy northward of Vesuvius was frequented in very early times by the Hellenes, and that there were Hellenic factories on its promontories and islands.

Probably the earliest evidence of such voyages is the localizing of the legend of Odysseus on the coasts of the Tyrrhene Sea.( 4) When men discovered the isles of Aeolus in the Lipari islands, when they pointed out at the Lacinian cape the isle of Calypso, at the cape of Misenum that of the Sirens, at the cape of Circeii that of Circe, when they recognized in the steep promontory of Terracina the towering burial-mound of Elpenor, when the Laestrygones were provided with haunts near Caieta and Formiae, when the two sons of Ulysses and Circe, Agrius, that is the "wild," and Latinus, were made to rule over the Tyrrhenians in the "inmost recess of the holy islands," or, according to a more recent version, Latinus was called the son of Ulysses and Circe, and Auson the son of Ulysses and Calypso--we recognize in these legends ancient sailors' tales of the seafarers of Ionia, who thought of their native home as they traversed the Tyrrhene Sea.
The same noble vividness of feeling, which pervades the Ionic poem of the voyages of Odysseus, is discernible in this fresh localization of the same legend at Cumae itself and throughout the regions frequented by the Cumaean mariners.
Other traces of these very ancient voyages are to be found in the Greek name of the island Aethalia (Ilva, Elba), which appears to have been (after Aenaria) one of the places earliest occupied by Greeks, perhaps also in that of the seaport Telamon in Etruria; and further in the two townships on the Caerite coast, Pyrgi (near S.

Severa) and Alsium (near Palo), the Greek origin of which is indicated beyond possibility of mistake not only by their names, but also by the peculiar architecture of the walls of Pyrgi, which differs essentially in character from that of the walls of Caere and the Etruscan cities generally.
