Fire was closely related to the Underworld. Much like the medieval Christian concept of Hell, the Egyptian Underworld was filled with fiery rivers and lakes. The Underworld was also inhabited by many fire demons who threatened the wicked dead. These demons wear depicted with the hieroglyph of the brazier on their heads. The Lakes of Fire in the Underworld were drawn like normal pools of water, but with braziers on each side and fiery red (instead of blue) wavy lines transversing them. The Lakes of Fire were also shown with baboons seated at each corner. These lakes were only troublesome for the wicked, the righteous could drink of them and be refreshed. The righteous could also transform into shooting flames and destroy their enemies.
