The first of all barbarians to present gifts to the Olympian Zeus was the Tuscan king Arimnus, perhaps a ruler of Ariminum.

Spina and Caere had their special treasuries in the temple of the Delphic Apollo, like other communities that had regular dealings with the shrine; and the sanctuary at Delphi, as well as the Cumaean oracle, is interwoven with the earliest traditions of Caere and of Rome.
These cities, where the Italians held peaceful sway and carried on friendly traffic with the foreign merchant, became preeminently wealthy and powerful, and were genuine marts not only for Hellenic merchandise, but also for the germs of Hellenic civilization.
Hellenes 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.
