 In several of the manuscripts Xolotl is depicted striving at this game against other gods.For example, in the Codex Mendoza we see him playing with the moon-god, and can recognize him by the sign ollin which accompanies him, and by the gouged-out eye in which that symbol ends.Seler thinks "that the root of the name ollin suggested to Mexicans the motion of the rubber ball "olli" and, as a consequence, ball-playing."
