What is the name of the Aztec goddess of obsidian and sacrifice?

Itzpapalotl is the Aztec goddess associated with obsidian, sacrifice, war, and death.

Her Nahuatl name is commonly translated as “Obsidian Butterfly,” although some interpretations favor “Clawed Butterfly.” She was often represented as a frightening skeletal or warrior-like figure with wings edged by sharp obsidian or flint blades. These attributes connect her to both butterflies and the dangerous, cutting power of ritual stone.

Itzpapalotl was also queen of the Tzitzimimeh, star beings feared as destructive demons during solar eclipses. She was linked with Tamoanchan, a sacred paradise associated in some traditions with creation and with people who died in infancy. Myths also describe her as the mother of Mixcoatl, an important hunting and ancestral deity.

She is sometimes confused with Mictlantecuhtli, the male ruler of the underworld, or Coyolxauhqui, the moon-associated warrior goddess dismembered by Huitzilopochtli. Xipe Totec was another major deity connected with renewal and sacrifice, but he was not the obsidian goddess.
