The Liber Linteus Zagrabiensis is the longest Etruscan text and the only extant linen book, dated to the 3rd century BC, making it arguably the oldest extant European book. Much of it is untranslated because of the lack of knowledge about the Etruscan language, though the words and phrases which can be understood indicate that the text is most likely a ritual calendar. Miles Beckwith points out with regard to this text that "in the last thirty or forty years, our understanding of Etruscan has increased substantially," and L. B. van der Meer has published a word-by-word analysis of the entire text.

Etruscan was the language of the Etruscan civilization in the ancient region of Etruria, in Etruria Padana and Etruria Campana in what is now Italy. Etruscan influenced Latin but was eventually completely superseded by it. The Etruscans left around 13,000 inscriptions that have been found so far, only a small minority of which are of significant length; some bilingual inscriptions with texts also in Latin, Greek, or Phoenician; and a few dozen purported loanwords. Attested from 700 BC to AD 50, the relation of Etruscan to other languages has been a source of long-running speculation and study, with it mostly being referred to as one of the Tyrsenian languages, at times as an isolate and a number of other less well-known theories.
