The Statue of Chac Mool. Chac Mool is the term used to refer to a particular form of pre-Columbian Mesoamerican sculpture depicting a reclining figure with its head facing 90 degrees from the front, supporting itself on its elbows and supporting a bowl or a disk upon its stomach. These figures possibly symbolised slain warriors carrying offerings to the gods; the bowl upon the chest was used to hold sacrificial offerings, including pulque, tamales, tortillas, tobacco, turkeys, feathers and incense. In an Aztec example the receptacle is a cuauhxicalli (a stone bowl to receive sacrificed human hearts). Chacmools were often associated with sacrificial stones or thrones. Aztec chacmools bore water imagery and were associated with Tlaloc, the rain god. Their symbolism placed them on the frontier between the physical and supernatural realms, as intermediaries with the gods. The chacmool form of sculpture first appeared around the 9th century AD in the Valley of Mexico and the northern Yucatán Peninsula.
