Back in the day when I was studying ancient history at Columbia, one of the professors had a course on the Etruscans. Her father was a famous academician and archaeologist who worked on some of the earliest digs of Etruscan tombs and cities.
I remember that there was no translation of the Etruscan language and the aricle refers to it as a lost language still. Apparently no Rosetta stone has been found?
There’s at least one — but the relative lengths differ by a bit:
The Pyrgi Tablets: Bilingual Etruscan and Phoenician Text Inscribed in Gold (Circa 500 BCE)
