The traditional Mayas generally assume the Moon to be female, and the Moon's perceived phases are accordingly conceived as the stages of a woman's life. The Maya moon goddess wields great influence in many areas. Being in the image of a woman, she is associated with sexuality and procreation, fertility and growth, not only of human beings, but also of the vegetation and the crops. Since growth can also cause all sorts of ailments, the moon goddess is also a goddess of disease. Everywhere in Mesoamerica, including the Mayan area, she is specifically associated with water, be it wells, rainfall, or the rainy season. In the codices, she has a terrestrial counterpart in goddess I.
