Archaeologists have identified the first known case of deliberate mummification of a child sacrificed during the Inca capacocha ritual.
The discovery was made by an international research team led by Dagmara Socha of the University of Warsaw. Comprehensive examinations showed not only deliberate postmortem alteration of the body, but many injuries and pathological changes, including an enlarged oesophagus and calcifications in the lungs.
Capacocha was one of the most infamous rituals of the Inca Empire, involving the sacrifice of children and young women to major deities. Although Spanish chroniclers documented the practice after the conquest of South America, physical archaeological evidence for the ritual has remained sparse.
In the 1990s, archaeologist Johan Reinhard uncovered remarkably well-preserved frozen mummies on the summits of Peruvian volcanoes. Building on this work, recent bioarchaeological research focused on four naturally mummified children found on the Ampato and Sara Sara volcanoes in Peru, offering new insights into both the ritual itself and the treatment of victims after death.
Using computed tomography (CT) scanning, scientists for the first time have a non-invasive examination of capacocha victims. The extreme high-altitude conditions here, according to Dr. Socha — low temperatures; dry air; low microbial population — allowed remarkable preservation of soft tissues.
“CT imaging unveiled information that wouldn’t have been visible through conventional means,” Dr. Socha said. “This resulted in the first case of intentional mummification of a capacocha victim confirmed, along with many injuries and pathological disease states.”
Whereas some of the mummies appeared to be naturally preserved by freezing temperatures, others were damaged by lightning strikes — a common hazard on exposed Andean peaks.
Analysis showed that all the children died because of blows to the head. One 8-year-old girl suffered an intracerebral hematoma and had symptoms of Chagas disease. In yet another investigation, the famous mummy of the Lady of Ampato, or Juanita, was discovered with injuries to the chest and pelvis.
The presence of pre-existing diseases questions traditional beliefs — largely as based on historical evidence — about who chose children for sacrifice simply because they were physically “perfect.”
The most striking find pertained to a mummy named Ampato 4. CT scans showed displaced bones, missing skeletal elements, stones, and fragments of textile found inside the abdominal cavity. These discoveries point to intentional mummification and post-mortem manipulation. Researchers suspect the girl herself may have been sacrificed before being relocated with her body symbolically “repaired.”
These practices are in keeping with historical descriptions of population displacements in the Inca Empire, in which cities and settlements removed sacred objects — ancestor mummies included — in search of spiritual connections to new territory.
The results indicate that long after their death, capacocha victims continued to perform ritual and remained an integral feature of the religious life and collective memory of the empire. The study is part of a larger research project by Poland’s National Science Centre, which has recently resumed explorations of Andean peaks since 2024.
