Book of Amduat

The Amduat is an ancient Egyptian funerary text of the New Kingdom that tells the story of Ra, the Egyptian sun god, who makes a daily journey through the underworld, from the time the sun sets in the west till it rises again in the east. This journey is associated with imagery of continual death and rebirth, and the deceased Pharaoh is said to take this same journey through the underworld to be reborn and become one with Ra, residing with him forever. The Amduat names the inhabitants of the Duat, both good and bad, and its illustrations show the topography of the underworld, divided into 12 hours of the night, each representing different allies and enemies for the Pharaoh/sun god to encounter. The text provides information about the geography of the underworld and the names and descriptions of gods and monsters to aid the Ba (or soul) of the dead Pharaoh.learn more on wikipedia
