Etruscan remains one of the very few ancient Mediterranean languages that specialists can read only partially even after two centuries of sustained scholarly effort, since it is not clearly related to any other known language family in a way that would allow the kind of comparative reconstruction that helped decipher many other ancient scripts, meaning Etruscan decipherment has proceeded slowly through internal analysis of bilingual inscriptions, careful comparison across the roughly thirteen thousand surviving Etruscan texts, and identification of loan words and proper names rather than through a single decisive breakthrough comparable to the Rosetta Stone's role in deciphering Egyptian hieroglyphics. This incomplete decipherment directly limits confident translation of surviving Etruscan religious material, including the Liber Linteus, catalogued elsewhere in this atlas as the longest surviving Etruscan text, and shorter ritual inscriptions such as the petition to Nethuns also catalogued separately, meaning scholarly translations of this material carry more inherent uncertainty than translations of comparably ancient but better understood languages such as Akkadian or Egyptian, discussed in their own corpus entries elsewhere in this atlas.
