This compendium contains Volumes 1-3 of the original work. Volumes 1 and 2 are concerned with the Rosetta Stone, one of the most interesting and important objects in the National Collection of Egyptian Antiquities preserved in the British Museum. From it came the correct values of several of the letters of the Egyptian alphabet and it supplied many of the fundamental facts upon which the great superstructure of Egyptian decipherment was based. In the original Volume 3, the texts, with translations, from the Stele of Canopus are found.
