Itzpapalotl

This Aztec deity is typically in the form of a butterfly. When in this form, it represents the soul, which all life forms share. She, at times, takes on the form of a dear and linked with agriculture. Itzpapalotl is a female, and her male counterpart is Itzlacoliohqui (Carved Obsidian Knife), representing matter in its unconscious state. Tezcatlipoca is responsible for the spark of life. These three Aztec divinities form a trinity that guards the different conditions of life.
