The name of the deity Quetzalcoatl comes from the Nahuatl language, and it means "Precious Serpent," which is a reference to the serpent that is associated with the god. Quetzalcoatl was a prominent deity in the Aztec pantheon, as he was related to various phenomenon such as the planet Venus, the wind, and the sun and was also the patron of the Aztec priesthood. Aside from these, he was also associated with other gods such as Tlaloc, Huitzilopochtli, and Tezcatlipoca.

In ancient Mesoamerica, Quetzalcoatl was one of the most important gods. He was known for his role in the creation of the world and its inhabitants. His name combines the Nahuatl words coatl and quetzal. From 1200, Quetzalcoatl was regarded as the patron deity of merchants and priests in Central Mexico. He was also known for inventing the calendar and was associated with various animals, such as the opossum and also the Morning Star Venus. He also discovered a mountain full of seeds and grains.
