[9] Rix's Tyrsenian family is supported by a number of linguists such as Stefan Schumacher,[10][11] Carlo De Simone,[12] Norbert Oettinger,[13] Simona Marchesini,[8] and Rex E.

[15] On the other hand, few lexical correspondences are documented, at least partly due to the scant number of Raetic and Lemnian texts and possibly also to the early date at which the languages split.

[17] Carlo De Simone and Simona Marchesini have proposed a much earlier date, placing the Tyrsenian language split before the Bronze Age.

[22][23] Scholars such as Norbert Oettinger, Michel Gras and Carlo De Simone think that Lemnian is the testimony of an Etruscan commercial settlement on the island that took place before 700 BC, not related to the Sea Peoples.

[24][12][25] Alternatively, the Lemnian language could have arrived in the Aegean Sea during the Late Bronze Age, when Mycenaean rulers recruited groups of mercenaries from Sicily, Sardinia and various parts of the Italian peninsula.

[28] The lack of recent Anatolian-related admixture and Iranian-related ancestry among the Etruscans, who are genetically closely related to the European cluster, might also suggest that the presence of a handful of inscriptions found at Lemnos, in a language related to Etruscan and Raetic, "could represent population movements departing from the Italian peninsula".

[31] Apollonius of Rhodes mentioned an ancient settlement of Tyrrhenians on Lemnos in his Argonautica (IV.1760), written in the third century BC, in an elaborate invented aition of Kalliste or Thera: in passing, he attributes the flight of Sintian Lemnians to the island Kalliste to "Tyrrhenian warriors" from the island of Lemnos.

[35][36] T. B. Jones proposed in 1950 reading of Eteocypriot texts in Etruscan, which was refuted by most scholars but gained popularity in the former Soviet Union.
