“In Auxerre Cathedral in northern France, and most likely in cathedrals in Sens and Amiens (and perhaps Chartres, as well), clergy gathered around the labyrinth [patterned into the floor of the nave], danced in a circle, and tossed a ball from person to person. These games, according to medieval religious observers, had ties to pagan practices. In certain places, they were incorporated into church rituals for hundreds of years.”
