In 1842 Egyptologist
Karl Richard Lepsius first named the class of Egyptian papyrus known as
The Book of the Dead when he edited papyrus Turin 1791 as an exemplar, and had it published in Leipzig in 1842 as
Das Todtenbuch der Ägypter nach dem hieroglyphischen Papyrus in Turin mit einem Vorworte zum ersten Male Herausgegeben. This was the first printed edition of
The Book of the Dead. The modern numbering of the
Book of the Dead spells (BD 1-165) is derived from Lepsius's edition of this papyrus.
