I’m not in the know, but given that nothing in Etruscan has ever been translated and it is considered a “lost language” (even in the thread title), I’d guess a heck of a long time. If these 70 characters somehow help decode the whole language, I’d be surprised, but this stele does seem to have some context to work with.

Thanks. These ancient mysteries are fascinating.
