Which evidence from "The Rosetta Stone” supports the claim that Thomas Young played a key role in helping to decipher the hieroglyphs on the Rosetta Stone? Unfortunately, Young abandoned his research, believing that the letters in the cartouche were just an exception . . . Young used an old code breaker's technique of looking for a crib, or a word that can be identified in the text. Champollion deciphered the cartouche by identifying hieroglyphs translated by Young, and he used his knowledge of Coptic to discover that it belonged to the pharaoh Ramses. Young's results were published and fell into the hands of a talented linguist, Jean-Francois Champollion.
