1. The Liber Linteus Linen Codex 
The Liber Linteus, also known as the Linen Book of Zagreb, is the only surviving book of its kind in the world and the longest known example of Etruscan writing ever found. It survives only because the Roman Empire, which came into being years after the Etruscans had vanished, had a great affection for linen cloth.
