Seven bronze tables found near Eugubium (Gubbio) in Italy, in 1444. Of the inscriptions, five are Umbrian and Etruscan, and two are Latin.
“The Umbrian, the tongue of north-eastern Italy, is yet more fully represented to us by the Eugubine tablets ... supposed to be as old as the third and fourth centuries before our era.” -
