Oxomoco is an Aztec deity, the goddess of astrology and the calender. Oxomoco and Cipactonal were said to be the first human couple, and the Aztec comparison to Adam and Eve in regards to human creation and evolution.
They bore a son named Piltzin-tecuhtli, who married a maiden, daughter of Xochiquetzal. As an older woman she was also known as Itzpapalotl.
