Book of Gates
The most famous part of the "Book of Gates" today refers to the different races of humanity known to the Egyptians, dividing them up into four categories that are now conventionally labelled "Reth" (Egyptians), "Aamu" (Asiatics), "Nehesu" (Nubians), and "Themehu" (Libyans). These are depicted in procession entering the next world.
