In Aztec mythology, Huitzilopchtli, also spelled Uitzilopochtli ("hummingbird of the south" or "he of the south" or "hummingbird on the left"), was a god of war and a sun god and the patron of the city of Tenochtitlan. His mother was Coatlicue, his father a ball of feathers (or, alternatively, Mixcoatl). He was sometimes said to have had a sister, Malinalxochi. His messenger was Paynal.
His sister, Coyolxauhqui, killed their mother, Coatlicue, because she became pregnant in a shameful way (by a ball of feathers). Her fetus, Huitzilopchtli, sprang from her stomach and killed Coyolxauhqui, along with many of the brothers and sisters. He then tossed her head into the sky, becoming the moon, so that his mother would be comforted in seeing her daughter in the sky every night.
