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.
Found it out while watching ancient aliens... hope no re-post but found it interesting that apparently they think vampires actually existed at one point... Start watching at around 20 mins in on this video:
oh and apparently also zombies existed at some point too... found this information interesting and thought I'd share.
But anyways thats a bit off topic, i'd rather go home and eat some fancy dish soaps.
