In philology, decipherment is the discovery of the meaning of texts written in ancient or obscure languages or scripts.[1] Decipherment in cryptography refers to decryption.[2]

Ancient languages

In a few cases, a multilingual artifact has been necessary to facilitate decipherment, the Rosetta Stone being the classic example. Statistical techniques provide another pathway to decipherment, as does the analysis of modern languages derived from ancient languages in which undeciphered texts are written. Archaeological and historical information is helpful in verifying hypothesized decipherments.
