The Amduat, also called "Book of What is in the Underworld", is a corpus of funerary texts and vignettes. It describes the journey of the sun god through the 12 hours of the night, from its setting to its rising in the morning.
The Amduat (literally "That Which Is In the Afterworld") is an important Ancient Egyptian funerary text of the New Kingdom. Like many funerary texts, it was written on the inside of the tomb for reference by the deceased. Unlike other funerary texts, however, it was reserved only for pharaohs or very favored nobility.
