Written by perhaps the most prolific, erudite Egyptologist of the 20th century, this solid guide to hieroglyphics remains the standard introduction. Budge gives the history of hieroglyphic writing, its evolution into hieratic and demotic scripts, and the fascinating tale of its decipherment by Young, Champollion, Åkerblad, and others.
