In Aztec mythology, Patecatl is a god of healing and fertility, and the discoverer of peyote as well as the `lord of the root of pulque `. With Mayahuel, he was the father of the Centzon Totochtin. In the Aztec calendar, Patecatl is the lord of the thirteen days from 1 Monkey to 13 House. The preceding thirteen days are ruled over by Mictlantecu.....
