This is a three volume collection of texts and commentary about the Ancient Egyptian alternate reality called the Tuat. The Tuat was both the region that the boat of the Sun God Ra traversed during the night, and the place where inhabitants of this world went after death.
A description of the Tuat, and its inhabitants and portals, was inscribed on the walls of the tombs of all social strata.
Vol. I: The Book of Am-Tuat
