Shirtless men perform for Charles V with a red object made of this material in Christoph Weiditz’s “Costume Book.” That object made of this material is replaced with a blue man near a mountain in the “Paradise” Mural 3 at Tepantitla. To create this material, juice from the morning glory was mixed with Castilla elastica. In the Nahuatl language, the Olmecs were named for producing this material. A nine-pound object made of this material was struck with a manopla handstone and the (*) hips of players in ōlla·malīztli, (10[1])which was played on an I-shaped court. A ball made of this material was hit through a horizontal stone hoop in pok-ta-pok, a ballgame whose losers were often decapitated. For 10 points, name this material that Mesoamerican civilizations created by extracting and drying tree sap. ■END■
