Quetzalcoatl is a composite name in the Nahuatl language derived from 'quetzalli' and used to describe the large, precious green feathers of the sacred quetzal bird; and 'coatl', meaning snake. It is one of the main divinities of the Mesoamerican civilizations and the feathered serpent, its most iconic incarnation, reigned for many long centuries over pre-Columbian America. This powerful symbol of Mesoamerican culture was the core of worship and sacred rituals. The related myths and legends appear in the writings of the colonial period. In conjunction with the evening star, it was considered to govern the cycle of time from dawn to dusk. This deity of the summer winds was naturally closely associated with agriculture and in particular with corn farming, as well as being the sovereign protector of goldsmiths and artisans, and the inventor of the calendar.
