Xiuhcoatl

In Aztec religion, Xiuhcōātl [ʃiʍˈkoːaːt͡ɬ] was a mythological serpent, regarded as the spirit form of Xiuhtecuhtli, the Aztec fire deity sometimes represented as an atlatl or a weapon wielded by Huitzilopochtli. Xiuhcoatl is a Classical Nahuatl word that translates as "turquoise serpent" and also carries the symbolic and descriptive translation of "fire serpent".

Xiuhcoatl was a common subject of Aztec art, including illustrations in Aztec codices, and was used as a back ornament on representations of both Xiuhtecuhtli and Huitzilopochtli.^[1] Xiuhcoatl is interpreted as the embodiment of the dry season and was the weapon of the sun.^[2] Apparently, the royal diadem (or xiuhuitzolli, "pointed turquoise thing") of the Aztec emperors represented the tail of the Xiuhcoatl, the fire serpent.^[3]
