The Book of Caverns is an important Ancient Egyptian funerary text of the New Kingdom. Like many funerary texts, it was written on the inside of tombs for reference by the deceased. It describes the journey of the sun god Ra through the six caverns of the underworld, focusing on rewards and punishments in the afterlife. The earliest appearance of this work is in the left hand wall of the Osireion in Abydos. It first appears in the Valley of the Kings, in the tomb of Ramesses IV, in place of Amduat, where it was recorded by Jean Francois Champollion in his letters from Egypt.
