By connecting the ancient maritime commerce of the Etruscans with the piracy of the Lydians, and then by confounding (Thucydides is the first who has demonstrably done so) the Torrhebian pirates, whether rightly or wrongly, with the bucaneering Pelasgians who roamed and plundered on every sea, there has been produced one of the most mischievous complications of historical tradition.

The term Tyrrhenians denotes sometimes the Lydian Torrhebi--as is the case in the earliest sources, such as the Homeric hymns; sometimes under the form Tyrrheno-Pelasgians or simply that of Tyrrhenians, the Pelasgian nation; sometimes, in fine, the Italian Etruscans, although the latter never came into lasting contact with the Pelasgians or Torrhebians, or were at all connected with them by common descent.
Settlements of the Etruscans in Italy It is, on the other hand, a matter of historical interest to determine what were the oldest traceable abodes of the Etruscans, and what were their further movements when they issued thence.
Various circumstances attest that before the great Celtic invasion they dwelt in the district to the north of the Po, being conterminous on the east along the Adige with the Veneti of Illyrian (Albanian ?) descent, on the west with the Ligurians.

This is proved in particular by the already-mentioned rugged Etruscan dialect, which was still spoken in the time of Livy by the inhabitants of the Raetian Alps, and by the fact that Mantua remained Tuscan down to a late period.
To the south of the Po and at the mouths of that river Etruscans and Umbrians were mingled, the former as the dominant, the latter as the older race, which had founded the old commercial towns of Atria and Spina, while the Tuscans appear to have been the founders of Felsina (Bologna) and Ravenna.

A long time elapsed ere the Celts crossed the Po; hence the Etruscans and Umbrians left deeper traces of their existence on the right bank of the river than they had done on the left, which they had to abandon at an early period.
All the regions, however, to the north of the Apennines passed too rapidly out of the hands of one nation into those of another to permit the formation of any continuous national development there.
Etruria Far more important in an historical point of view was the great settlement of the Tuscans in the land which still bears their name.
Although Ligurians or Umbrians were probably at one time( 5) settled there, the traces of them have been almost wholly effaced by the Etruscan occupation and civilization.

In this region, which extends along the coast from Pisae to Tarquinii and is shut in on the east by the Apennines, the Etruscan nationality found its permanent abode and maintained itself with great tenacity down to the time of the empire.
