Religions of the pre-Columbian cultures of Mexico and Central America, notably the Olmec , Maya , Toltec , and Aztec .
All religions of Mesoamerica were polytheistic. The gods had to be constantly propitiated with offerings and sacrifices. The religions also shared a belief in a multilevel universe that had gone through five creations and four destructions by the time of the Spanish conquest. Mesoamerican religions heavily emphasized the astral bodies, particularly the sun, the moon, and Venus, and the observations of their movements by astronomer-priests were extraordinarily detailed and accurate. The Aztecs approached the supernatural through a complex calendar of ceremonies that included songs, dances, acts of self-mortification, and human sacrifices performed by a professional priesthood, in the belief that the welfare of the universe depended on offerings of blood and hearts as nourishment for the sun. The Mayan religion likewise called for human sacrifices, though on a smaller scale. Information on the astronomical calculations, divination, and ritual of the Mayan priests has been gathered from the Maya Codices . See also Mesoamerican civilization .
