According to Aztec mythology, Xolotl was a deity normally associated with Quetzalcoatl, one of the most important gods in the Aztec pantheon. As a matter of fact, Xolotl was regarded to be the twin of Quetzalcoatl. Unlike his twin, however, Xolotl is traditionally given negative attributes, which is evident in his physical form as well as how he is symbolized elsewhere.
