From Evidence May Back Human Sacrifice Claims:
Indian pictorial texts known as “codices,” as well as Spanish accounts from the time, quote Indians as describing multiple forms of human sacrifice.Victims had their hearts cut out or were decapitated, shot full of arrows, clawed, sliced to death, stoned, crushed, skinned, buried alive or tossed from the tops of temples.
Children were said to be frequent victims, in part because they were considered pure and unspoiled.
“Many people said, ‘We can’t trust these codices because the Spaniards were describing all these horrible things,’ which in the long run we are confirming,” said Carmen Pijoan, a forensic anthropologist who found some of the first direct evidence of cannibalism in a pre-Aztec culture over a decade ago: bones with butcher-like cut marks.
There’s more:
“The sacrifice involved burning or partially burning victims,” Velez Saldana said. “We found a burial pit with the skeletal remains of four children who were partially burned, and the remains of four other children that were completely carbonized.”While the remains don’t show whether the victims were burned alive, there are depictions of people — apparently alive — being held down as they were burned.
The dig turned up other clues to support descriptions of sacrifices in the Magliabecchi codex, a pictorial account painted between 1600 and 1650 that includes human body parts stuffed into cooking dishes, and people sitting around eating, as the god of death looks on.
“We have found cooking dishes just like that,” said archaeologist Luis Manuel Gamboa. “And, next to some full skeletons, we found some incomplete, segmented human bones.” However, researchers don’t know whether those remains were cannibalized.
In 2002, government archaeologist Juan Alberto Roman Berrelleza announced the results of forensic testing on the bones of 42 children, mostly boys around age 6, sacrificed at Mexico City’s Templo Mayor, the Aztec’s main religious site, during a drought.
All shared one feature: serious cavities, abscesses or bone infections painful enough to make them cry.
“It was considered a good omen if they cried a lot at the time of sacrifice,” which was probably done by slitting their throats, Roman Berrelleza said.
