As for the Etruscans, its often debated that they where either Mycenaean Greeks, western ANATOLIANS or even more exotic elements such as Armenians. They competed with the Greeks but received much cultural influence from them, even slightly "hellenizing" their gods and religious beliefs. If the Etruscans where in fact related to Lydians as is assumed, it becomes easy to see, through Lydian religious gods and customs, how we start getting much closer to the Middle East, sharing gods with Assyrians and such people's. as for linguistic evidence, Etruscan is not very as greek is, upon analyzing modern day Armenian although, it becomes clear that Etruscan is shockingly similar to Armenian, which has already been proposed as being home of the original pelasgians, Phrygians, etc. an excellent book to read would be Robert Ellis's " The Armenian origin of the Etruscans" written based on cultural, historical and linguistic evidence. Once upon a time, the roman tongue expanded and killed off most expanding Celtic languages. And once upon a time, the greek tongue expanded, killing off "Armenian" dialects which where spread from Italy to Asia Minor and in Armenia, until the only dialect akin to Armenian left was Armenian itself, still spoken upon the throne of its origin in Armenia herself. The Thracian race was traced from the far frontiers of Medea to the doorstep of central Italy. Some of the furthest to the east of this race where the Armenians. The furthest to th west where the Etruscans and raetians.
