Etruscan language
In 1998 the German linguist Helmut Rix proposed that three then unclassified ancient languages belonged to a common linguistic family he called 'Tyrrhenian': the Etruscan language spoken in Etruria, the Rhaetic language of the southern Alps, and the Lemnian language, only attested by a small number of inscriptions from the Greek island of Lemnos in the Aegean Sea.
