Beginning in the sixth century B.C., varying versions of a ball game spread across Mesoamerica, and ball courts can be found in many pre-Hispanic cities. Stone rings, with openings just wide enough to allow the ball to pass through, hung vertically on each side of the court and opposing players tried to knock the ball through the rings using only their hips, buttocks and knees. By Elisa Camarena, this sculpture replicates a ball court ring from the Maya culture; It is displayed on a pinewood stand.
