In Aztec mythology the Lords of the Day (Classical Nahuatl: Tonalteuctin)[citation needed] are a set of thirteen gods that ruled over a particular day corresponding to one of the thirteen heavens.[citation needed] They were cyclical, so that the same god recurred every thirteen days. In the Aztec calendar, the lords of the day are[1]
Quetzalcoatl, god of wisdom, life, knowledge, morning star, fertility, patron of the winds and the light, the lord of the West.
Tezcatlipoca, god of providence, matter and the invisible, ruler of the night, Great Bear, impalpable, ubiquity and the twilight, the lord of the North.
