Codes, cyphers, and the National Cryptologic Museum

Outside the National Cryptologic Museum gift store is this replica of the Rosetta Stone. Created around 196 BC, it displays a decree from an Egyptian king, written in Egyptian hieroglyphs, Demotic script and ancient Greek. Discovered by a French soldier during France's invasion of Egypt in 1799, it provided the key to unlocking Egyptian hieroglyphs, much as modern code breakers look for keys in breaking coded texts. The real Rosetta Stone is on display at the British Museum in London.
