Skeletons found at an unearthed site in Mexico show Aztecs captured, ritually sacrificed and partially ate several hundred people traveling with invading Spanish forces in 1520.

Skulls and bones from the Tecuaque archeological site near Mexico City show about 550 victims had their hearts ripped out by Aztec priests in ritual offerings, and were dismembered or had their bones boiled or scraped clean, experts say.

The prisoners were kept in cages for months while Aztec priests from what is now Mexico City selected a few each day at dawn, held them down on a sacrificial slab, cut out their hearts and offered them up to various Aztec gods.

Teeth marks

"It was a continuous sacrifice over six months. While the prisoners were listening to their companions being sacrificed, the next ones were being selected," Martinez said, standing in his lab amid boxes of bones, some of young children.

"You can only imagine what it was like for the last ones, who were left six months before being chosen, their anguish."

The priests and town elders, who performed the rituals on the steps of temples cut off by a perimeter wall, sometimes ate their victims' raw and bloody hearts or cooked flesh from their arms and legs once it dropped off the boiling bones.

Knife cuts and even teeth marks on the bones show which ones had meat stripped off to be eaten, Martinez said.
