The Danza de los Voladores (Dance of the Flyers) is a ceremony/ritual which has its roots in the pre-Hispanic period and presently best known as associated with the town of Papantla, Veracruz. It is believed to have originated with the Nahua, Huastec and Otomi peoples in central Mexico, and then spread throughout most of Mesoamerica. The ritual consists of dance and the climbing of a 30 meter pole from which four of the five participants then launch themselves tied with ropes to descend to the ground. (from Wikipedia)
