MEXICO CITY, MEXICO—A figure of the fire god Huehueteotl carved from volcanic stone has been found buried in the top of the Pyramid of the Sun at Teotihuacan. “Once we didn’t find the bottom of the platform, upon further digging we figured out it was a pit,” said Nelly Nuñez of the National Institute of Anthropology and History. The sculpture, which weighs more than 400 pounds, had been placed in the pit beneath a platform that was probably the foundation for a temple. Two stone pillars were also found in the pit. Huehueteotl is associated with wisdom and rulership, and is depicted as a seated old man wearing a fire source on his head.
