Archaeologists have long known that ancient societies on Peru’s north coast killed male prisoners of war and drank their blood in grisly sacrifice ceremonies. Now researchers have found an unusual twist on that scene: the remains of six young women, sacrificed in a ritual in about A.D. 850. Their bones were found under the floor of a mudbrick temple complex in Pucalá, near the city of Chiclayo. The women show no signs of disease and had been wrenched into odd positions. Four lay atop each other in a single grave, and two others rested a few feet away, accompanied by a baby llama. Most are missing rib bones, indicating that their remains were left exposed and that their organs had been eaten by vultures after death, a “purification rite” that the bodies of male sacrifice victims were also subjected to, says archaeologist Edgar Bracamonte of the Royal Tombs of Sipán Museum.
