Cuauhxicalli

A cuauhxicalli or quauhxicalli (Nahuatl: [kʷaːʍʃiˈkalːi], meaning "eagle gourd bowl") was an altar-like stone vessel used by the Aztec in sacrificial ceremonies, believed to be for holding human hearts. A cuauhxicalli would often be decorated with animal motifs, commonly eagles or jaguars. Another kind of cuauhxicalli is the Chacmool-type, which is shaped as a reclining person holding a bowl on his belly.
