The name "Quetzalcoatl" literally means quetzal-bird snake or serpent with feathers of the Quetzal (which implies something divine or precious) in the Nahuatl language. The meaning of his local name in other Mesoamerican languages is similar.

The Maya knew him as Kukulkna; the Quiche as Gukumatz. The Feathered Serpent deity was important in art and religion in most of Mesoamerica for close to 2,000 years, from the Pre-Classic era until the Spanish Conquest.

Gukumatz was a culture hero who taught the Toltecs, and later the Maya, the arts of civilization, including codes of law, agriculture, fishing and medicine. He came from an ocean, and eventually returned to it. According to Mayan legend, Gukumatz will return to the Earth during the End Times. He also represents the forces of good and evil, similar to the ying-yang paradigm of Oriental religions.

Gukumatz was a god of the four elements of fire, earth, air and water, and each element was associated with a divine animal or plant:

Air — Vulture
Earth — Maize
Fire — Lizard
Water — Fish

Dragons
Sometimes serpents and dragons are used interchangeably, having similar symbolic functions. The venom of the serpent is thought to have a fiery quality similar to a fire spitting dragon. The Greek Ladon and the Norse Níðhöggr (Nidhogg Nagar) are sometimes described as serpents and sometimes as dragons. In Germanic mythology, serpent (Old English: wyrm, Old High German: wurm, Old Norse: ormr) is used interchangeable with the Greek borrowing dragon (OE: draca, OHG: trahho, ON: dreki). In China, the Indian serpent nāga was equated with the lóng or Chinese dragon. The Aztec and Toltec serpent god Quetzalcoatl also has dragon like wings, like its equivalent in Mayan mythology Gukumatz ("feathered serpent").
