Mictlantecutli
It was said that if you died and were doomed to the underworld that a person traveled four years and cross nine rivers on the back of a dog. When the corpse was buried a dog would be sacrificed and laid besides the victim's body. The dog would be useful in aiding his master across the wide stretch of water called the chicunauhapan ("ninefold stream") that flows around the final abode of the dead. To entrance to Mictlan was said to be to be through a cave conceived as the gaping jaws of a reptilian Earth monster.Their are nine levels to the underworld with each level the soul is challenged on its way to the ninth layer. When it reached Mictlan it would rest their for eternity. (Neumann 1975)
