Not only has Proto-Indo-European been traced back to Turkish farmers, but now the links between Sumerian and Lemnite Etruscan and Turkish have been enumerated. [And there’s plenty more information at the Caucasus Foundation.] This is what happens when you try to figure out when the hero known as Gilgamesh got his new pronunciation: Bilgamesh. Philologists should take heart and always remember the Sumerian proverb: hurum titi ursãgene. (Fools are the ribcages of heroes.) [via ETCSL (The Electronic Text Corpus of Sumerian Literature)]
