描述
Serpent imagery occurs throughout the religious iconography of Mesoamerica. The serpent played a very important role in Aztec religion. The word for serpent in Nahuatl, the language spoken by the Aztecs, is coatl and is associated with several gods such as Quetzalcoatl (Feathered Serpent), Xiuhcoatl (Fire Serpent), Mixcoatl (Cloud Serpent) or Coatlicue (She of the Serpent Skirt), the mother of the Aztec god Huitzilopochtli. The habit of snakes to shed their skin each year probably led to them being used to convey ideas concerning renewal and transformation. Likewise the ability of many species to move freely between water, earth and the forest canopy helped underline their symbolic role as intermediaries between the different layers of the cosmos (underworld, earth and sky).
