This is the third of three volumes, first published in 1906, which treat the Egyptian theology of the afterlife. The first volume contains the complete hieroglyphic text of the Book Åm-?uat, with translations and reproductions of all the illustrations; the second, the hieroglyphic text of the short form of the Åm-Tuat and the Book of Gates. This volume explores the origin of the Books of the Other World, highlighting and comparing the most remarkable features, with prefatory remarks and a full index to the whole work.

The object of all the Books of the Other World was to provide the dead with a 'guide' or 'handbook, ' containing a description of the regions through which their souls would have to pass on their way to the Kingdom of Osiris, and which would supply them with the words of power and magical names necessary for an unimpeded journey from this world to the next.
