The Tabula Capuana, is an ancient terracotta slab, 50 by 60 cm, with a long inscribed text in Etruscan, dated to around 470 BCE, apparently a ritual calendar. About 390 words are legible, making it the second-most extensive surviving Etruscan text. The longest is the linen book (Liber Linteus), also a ritual calendar, used in ancient Egypt for mummy wrappings, now at Zagreb. The Tabula Capuana is located in the Altes Museum, Berlin.

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.
