What deity is the Mesoamerican counterpart of the Aztec god Q'uq'umatz?
Quetzalcoatl Quetzalcoatl ( ; ] ) (,    ) forms part of Mesoamerican literature and is a deity whose name comes from the Nahuatl language and means "feathered serpent". The worship of a feathered serpent is first documented in Teotihuacan in the first century BC or first century AD. That period lies within the Late Preclassic to Early Classic period (400 BC – 600 AD) of Mesoamerican chronology, and veneration of the figure appears to have spread throughout Mesoamerica by the Late Classic period (600–900 AD).
