The longest Etruscan text in existence, the Zagreb mummy wrapping, was written on a linen cloth later used in the mummification of a person in Egypt. Someone brought the mummy to Croatia in the 19th century and the text was later discovered.
Liber Linteus, oddly enough, I’ve got something on deck about the Etruscans, there’s a big ‘do’ going on at the Fine Arts in SF.
“One of the most exciting things in the exhibition is the Liber linteus.”
