High Quality Content by WIKIPEDIA articles! The Amduat (literally "That Which Is In the Afterworld", also translated as "Text of the Hidden Chamber Which is in the Underworld" and "Book of What is in the Underworld") is an important Ancient Egyptian funerary text of the New Kingdom. Like many funerary texts, it was found written on the inside of the pharaoh`s tomb for reference. Unlike other funerary texts, however, it was reserved only for pharaohs (until the 21st Dynasty almost exclusively) or very favored nobility.
