The Rosetta Stone is an Ancient Egyptian artifact which was instrumental in advancing modern understanding of Egyptian hieroglyphic writing. The stone contains carved text made up of three translations of a single passage: two in Egyptian language scripts (hieroglyphic and Demotic) and one in classical Greek. It was created in 196 BC, discovered by the French in 1799 at Rosetta and contributed greatly to the deciphering of the principles of hieroglyph writing in 1822 by the British scientist Thomas Young and the French scholar Jean-François Champollion. Comparative translation of the stone assisted in understanding many previously undecipherable examples of hieroglyphic writing.
The stone now resides at the British Museum.
