Greeks and Etruscans - Etruscan Maritime Power
Matters stood on a different footing with the "wild Tyrrhenians." The same causes, which in the province of Latium, and in the districts on the right bank of the Tiber and along the lower course of the Po that were perhaps rather subject to Etruscan supremacy than strictly Etruscan, had led to the emancipation of the natives from the maritime power of the foreigner, led in Etruria proper to the development of piracy and maritime ascendency, in consequence possibly of the difference of national character disposing the people to violence and pillage, or it may be for other reasons with which we are not acquainted.
The Etruscans were not content with dislodging the Greeks from Aethalia and Populonia; even the individual trader was apparently not tolerated by them, and soon Etruscan privateers roamed over the sea far and wide, and rendered the name of the Tyrrhenians a terror to the Greeks. It was not without reason that the Greeks reckoned the grapnel as an Etruscan invention, and called the western sea of Italy the sea of the Tuscans.
The rapidity with which these wild corsairs multiplied and the violence of their proceedings in the Tyrrhene Sea in particular, are very clearly shown by their establishment on the Latin and Campanian coasts. The Latins indeed maintained their ground in Latium proper, and the Greeks at Vesuvius; but between them and by their side the Etruscans held sway in Antium and in Surrentum.
The Volscians became clients of the Etruscans; their forests contributed the keels for the Etruscan galleys; and seeing that the piracy of the Antiates was only terminated by the Roman occupation, it is easy to understand why the coast of the southern Volscians bore among Greek mariners the name of the Laestrygones. The high promontory of Sorrento with the cliff of Capri which is still more precipitous but destitute of any harbour--a station thoroughly adapted for corsairs on the watch, commanding a prospect of the Tyrrhene Sea between the bays of Naples and Salerno--was early occupied by the Etruscans.
They are affirmed even to have founded a "league of twelve towns" of their own in Campania, and communities speaking Etruscan still existed in its inland districts in times quite historical. These settlements were probably indirect results of the maritime dominion of the Etruscans in the Campanian sea, and of their rivalry with the Cumaeans at Vesuvius.
