One of the most horrible deities of the underworld comes from the violent and frightening cosmology of the Maya civilization of Central America. The Mayan god of darkness, violence and sacrifice was Camazotz a flying bat god who inhabited Xibalba, the Mayan hell. Originally an anthropomorphic bat monster worshipped by the Zapotec Indians of Oaxaca, Camazotz was adopted into the Mayan pantheon as a vampire killer who reveled in slaughter. The deity appears throughout classical Mayan art and sculpture. Camazotz also features in the post-classical compendium of Mayan myths, the Popul Vuh, where he is master of a house of were-bats like himself.  There he (or one of his minions) claws off the heads of one of the story’s twin heroes during their attempt to defeat the lords of Xibalba in a marathon ball tournament.
