The Purpose Death Serves: Trauma Analysis of Human Sacrifices at El Pollo, Moche Valley, Peru

Abstract Human sacrifice is one of the most dramatic and enduring rituals known to ancient societies. Death of the victim represents the climax of the event because lethal violence produces vivid images that articulate power relations between the organizers, audience, and those sacrificed. This study reconstructs burial treatments, biological profiles, and trauma patterns on 49 human sacrifices excavated from the site El Pollo located 13 km from Chan Chan, the capital city of the Chimú Empire (AD 1050/1100–1450), in the Moche Valley, Peru. Children and adolescents ( n = 31/37) exhibit cutmarks to the anterior chest, which mirror the victim profiles and patterning of skeletal trauma documented at other Chimú sacrificial sites. Sacrifice at El Pollo also involved opening the chest cavities of adult males, dispatching bound male captives, and administering incisions to victim torsos to release blood. Given the administrative capacity and imperial enterprises of the Chimú Empire, these data indicate that sacrifice at El Pollo was part of a highly systematic ritual program staged throughout the Moche Valley and overseen by ruling elites at Chan Chan. This study provides evidence that sacrifice was modified to suit the civic-ceremonial needs of the empire and supported imperial efforts of militaristic expansion.
