Rosetta Stone 1

Above is how the stone is shown displaying by language.

Rosetta Stone was the original key to the decipherment of hieroglyphics. It was a damaged stone (much of the top is missing), found by Napoleon's invading army, at Rosetta (apparently French for Rashid) in northern Egypt, in 1799. It was captured by the British while still in Egypt, and is now in the British Museum. It is a stela (or stele, a stone with writing carved on it) with the same message (a decree from Ptolemy V) repeated three times, in hieroglyphics (Late Egyptian), in Demotic (another version of Egyptian), and in Greek. The first 26 or so lines are missing from the hieroglyphic part. The Rosetta Stone enabled Champollion and others to finally make progress deciphering hieroglyphics. Here are all 14 lines, as best I can do from examining photographs (with a few question marks for signs that couldn't be figure out):
