Mayan or Maya mythology is part of Mesoamerican mythology and comprises all of the Maya tales in which personified forces of nature, deities, and the heroes interacting with these play the main roles. The myths of the era have to be reconstructed from iconography. Other parts of Mayan oral tradition (such as animal tales, folk tales, and many moralising stories) are not considered here.
In Maya narrative, the origin of many natural and cultural phenomena is set out, often with the moral aim of defining the ritual relationship between humankind and its environment. In such a way, one finds explanations about the origin of the heavenly bodies (Sun and Moon, but also Venus, the Pleiades, the Milky Way); the mountain landscape; clouds, rain, thunder and lightning; wild and tame animals; the colors of the maize; diseases and their curative herbs; agricultural instruments; the steam bath, etc. The following more encompassing themes can be discerned.
The Popol Vuh describes the creation of the earth by a group of creator deities, as well as its sequel. The Book of Chilam Balam of Chumayel relates the collapse of the sky and the deluge, followed by the slaying of the earth crocodile, the raising of the sky and the erection of the five World Trees. The Lacandons also knew the tale of the creation of the Underworld.
The Popol Vuh gives a sequence of four efforts at creation: First were animals, then wet clay, wood, and then last, the creation of the first ancestors from maize dough. To this, the Lacandons add the creation of the main kin groupings and their 'totemic' animals. A Verapaz myth preserved by Las Casas in his 'Apologética Historia Sumaria' assigns the creation of humankind to artisan gods similar to the Popol Vuh monkey brothers. The creation of humanity is concluded by the Mesoamerican tale of the opening of the Maize (or Sustenance) Mountain by the Lightning deities.
The best-known hero myth, included in the Popol Vuh, is about the defeat of a bird demon and of the deities of disease and death by the Hero Twins, Hunahpu and Xbalanque.
