Read the excerpt from The Riddle of the Rosetta Stone.

Along with such insights, de Guignes advanced other ideas about the hieroglyphs that were as silly as any that had been proposed by Kircher or Horapollo. After comparing some Egyptian hieroglyphs with examples of Chinese picture writing, de Guignes announced that settlers from Egypt must have colonized China in ancient times.
