There is thus evidence that there was indeed at least a linguistic relationship between the Lemnians and the Etruscans. The circumstances of this are disputed; most scholars would ascribe Aegean Tyrrhenians to the Etruscan expansion from the 8th to the 6th centuries, putting the homeland of the Etruscans in Italy and the Alps, particularly because of their relation to the Alpine Rhaetian population. Another hypothesis connecting the Tyrrhenians and the Etruscans posits that the Etruscans derive at least partially from a 12th century BC invasion from the Aegean and Anatolia imposing itself over the Villanovan culture, with some scholars claiming a relationship or at least evidence of close contact between the Anatolian languages and the Etruscan language and adherents of the latter school of thought point to the legend of Lydian origin of the Etruscans referred to by Herodotus and Livy's statement that the Rhaetians were Etruscans driven into the mountains by the invading Gauls. Critics of the theory point to the very scanty evidence of a linguistic relationship of Etruscan with Anatolian and to Dionysius of Halicarnassus, who decidedly argues against an Etruscan-Lydian relationship. Furthermore, there is no archaeological evidence from material culture of such a cultural shift and of an eastern origins of the Etruscans, in modern times, all the evidence gathered so far by etruscologists points to an indigenous origin of the Etruscans. Just as the archaeological evidence is against the idea that the Rhaetians are descended from the Etruscans who fled from northern Italy because of the Gallic invasions, as the Rhaetians are archaeologically attested in their Alpine sites long before.
