The Rosetta Stone and Behistun Inscription, both multilingual writings, were instrumental to deciphering the ancient writing systems of Egypt and Mesopotamia, respectively

In epigraphy, a multilingual inscription is an inscription that includes the same text in two or more languages. A bilingual is an inscription that includes the same text in two languages (or trilingual in the case of three languages, etc.). Multilingual inscriptions are important for the decipherment of ancient writing systems, and for the study of ancient languages with small or repetitive corpora.
