The first interpretation is that the chacmool is an offering table (or "tlamanalco") to receive gifts such as pulque, tamales, tortillas, tobacco, turkeys, feathers and incense. The second is that the chacmool was a "cuauhxicalli" to receive blood and human hearts; this use is particularly relevant to the Aztecs, who used a "cuauhxicalli" bowl in place of the usual disc-altar. These bowls may have accepted these blood offerings directly or may have been holders for portable "cuauhxicalli" bowls that were placed within them. A chacmool from Tlaxcala has a bloodied heart sculpted on the underside, supporting this interpretation.
