The rituals of the Aztec
As you may already know, the Aztec had many strange rituals, the most common being sacrifice. They also would have a priest dress as a god once a year. The impersonator was called a "ixiptlatli." They also would reenact myths. My favorite Aztec myth is the one of their creation. Some gods, with really long names, destroyed the old earth and made a new one, even sacrificing a god for the creation of the sun. Just like this story says, the Aztec had strong believes about rebirth.
