According to Aztec mythology, where did the sun and the moon originate?

In Aztec mythology, the origins of the sun and the moon are intricately tied to the narrative of Tecuciztecatl and Nanahuatzin. According to the myth, the gods convened and decided that a great sacrifice was necessary to create the sun. Tecuciztecatl, a wealthy and proud god, and Nanahuatzin, a humble and poor god, both volunteered to make this sacrifice.

Ultimately, it was Nanahuatzin, after demonstrating his willingness and humility, who transformed into the sun. Tecuciztecatl, although initially reluctant, followed suit and became the moon. This act of sacrifice not only embodies themes of dualism within the mythology but also establishes a symbolic relationship between the sun, the moon, and the qualities of their respective deities.
