Aztec skull wall of Templo Mayor in Tenochtitlan (Mexico City) Sacrificial victims were usually war captives but children were also sacrificed as their tears were considered a favorable link with the life-giving raindrops from Tlaloc. The priests who carried out this carnage, on occasion, ate the flesh of the victims, with the heart being the most prized, if it had not already been burned in offering to the gods. The Aztec ruler, privileged nobles, and those who had captured the victims in war also participated in this symbolic feast.~ image courtesy Wolfgang Sauber, info courtesy http://www.ancient.eu/Templo_Mayor/
