One of three major myths about the sun god compiled in the New Kingdom(1550–1069 B.C.), the Book of Gates refers to the 12 gates separating the hours of the night.
It is a vast body of writings, spells, and incantations collected from the religious literature stored in temple libraries. The Gates divide the 12 hours of the night and separate the enemies that the sun god will encounter.
Similar myths tell a slightly different story of RE's perilous journey through the 12 hours of the night, and of his joyous rebirth in the eastern sky each morning.
