The Book of Caverns is an important ancient Egyptian netherworld book of the New Kingdom. Like all other netherworld books, it is also attested on the inside of kings' tombs for the benefit of the deceased. It describes the journey of the sun god Ra through the six caverns of the underworld, focusing on the interaction between the sun god and the inhabitants of the netherworld, including rewards for the righteous and punishments for the enemies of the worldly order, those who fail their judgment in the afterlife.
