What happened

The Inca practiced capacocha, a ritual in which selected children, often from elite or provincial families, were taken from their communities, brought through a period of ceremony, and then sacrificed, frequently at high-altitude shrines on mountain summits considered sacred. In 1999, archaeologists Johan Reinhard and Constanza Ceruti discovered three child mummies near the 22,110-foot summit of the Llullaillaco volcano on the Argentina-Chile border, since named the Llullaillaco Maiden, the Llullaillaco Boy, and the Lightning Girl. National Geographic reported that hair analysis of the Maiden showed she had consistently used coca at a high level during the last year of her life, with alcohol consumption surging sharply only in her final weeks, a pattern researchers read as evidence of a year of preparatory ceremonies that ended with the children being deliberately sedated, allowed to fall asleep, and left in a stone tomb roughly 1.5 meters underground to die of exposure.

Why it matters

The Llullaillaco mummies give direct physical evidence, rather than only Spanish written testimony, for how capacocha actually worked, showing a months-long ritual process rather than a single violent act, and the mummies' near-perfect preservation at extreme altitude has let scientists reconstruct details of Inca diet, textile-making, and ritual practice that no written source records.

How we know

The evidence is direct physical and chemical analysis: hair segments record a chronological log of what each child consumed in the months before death, since hair grows at a known rate, and the mummies themselves were naturally freeze-dried and preserved by the high-altitude cold and low humidity, not through any embalming process.
