Quetzalcóatl

Quetzalcóatl (pron. Quet-zal-co-at) or 'Plumed Serpent' was one of the most important gods in ancient Mesoamerica. Quetzalcóatl was the god of winds and rain, and the creator of the world and humanity. A mix of bird and rattlesnake, his name is a combination of the Nahuatl words quetzal (the emerald plumed bird) and coatl (serpent).

In Central Mexico from 1200, the feathered serpent god was considered the patron god of priests and merchants as well as the god of learning, science, agriculture, crafts and the arts. He also invented the calendar, was identified with the Morning Star Venus, the rising morning star, he was associated with opossums and even discovered corn (maize) with the help of giant red ant that led him to a mountain packed full of grain and seeds. He was known as Kukulkán to the Maya, Gucumatz to the Quiché of Guatemala, and Ehecatl to the Gulf Coast Huastecs.

Quetzalcóatl was the son of the primordial androgynous god Ometeotl. In Aztec mythology he was the brother of Tezcatlipoca, Huizilopochtli and Xipe Totec. He is the 9th of the 13 Lords of the Day and is often associated with the rain god Tláloc. The god was particularly associated with the sacred site of Cholula, an important place of pilgrimage from 1200, and all round buildings of the Aztec culture were dedicated to the deity.
