In the Maya creation story of the Popol Vuh, we are told that the decapitated head of the Hero Twins father Hun Hunahpu after being sacrificed in the Underworld by the Lords of Xibalba, after a ballgame, was placed in a tree, and that the daughter of one of the Lords of Xibalba named Xquic becomes impregnated when she visits the decapitated head for herself, and that the severed head of Hun Hunahpu spits in the palm of her hand, impregnating her, thus creating the miraculous birth of the legendary Hero Twins. According to Wasson (in Furst 1976, p.85) divine spittle is also related to the origin of the Amanita mushroom in Siberia.
We also are told in the Popol Vuh that one of the creator gods named Gucumatz, whose name literally means feathered serpent, (the Quiche Mayan translation of Quetzalcoatl) created the earth, raised the sky, and fashioned humans from maize.
