A chacmool is a Mayan, Toltec, or Aztec statue of a reclining man holding a bowl over his abdomen. The chacmool's knees and elbows are bent, and the figure is made of clay or stone.
Because chacmools are often found at the entrances to shrines, archeologists speculate that sacred offerings were put into the bowl. The chacmool may have been a messenger bewteen humans and gods. There is some wilder speculation that chacmools near Mayan altars were used to hold the hearts cut out from human sacrifices.
Chac is the Mayan god of rain and fertility.
