One of the most intriguing activities depicted in Moche art is Ceremonial Badminton, an event where one team used spear throwers to propel feathered objects into the air, while a second team used spear throwers with attached cross pieces to entangle the feathered objects. Enacted by the Moche over a period of five centuries, Ceremonial Badminton appears to have been part of a large festival in which various ritual activities were performed, accompanied by music, dancing, drinking, and feasting. A detailed study of 16 depictions of this ceremony, combined with extensive experimentation and reenactments, provide a much greater understanding of it than was previously possible.
