Xolotl: god of fire and of bad luck. He was the twin of Quetzalcoatl, the pair being sons of the virgin Coatlicue, and was the dark personification of Venus, the evening star. He guarded the sun when it went through the underworld at night. He also assisted Quetzalcoatl in bringing humankind and fire from the underworld. He is depicted with physical deformities, is associated with dwarves and hunchbacks, and is the patron god of twins, who were considered monstrous and were feared.
