New chemical analysis of eight Inca mummies has revealed a sophisticated use of psychoactive substances during ritual sacrifices. The University of Warsaw study shows that cocaine, alcohol, and harmine were used to assist children in their spiritual transition.
The cocaine, alcohol, and harmine ritual cocktail
The University of Warsaw study identified a complex pharmacological approach used to prepare children for their transition to the divine. by analyzing keratin structures in hair and nails, researchers found that while cocaine derived from coca leaves was present in all eight mummies, the specific mixtures varied. According to the research team, the substances identified included:
- Cocaine: Found universally across all studied remains.
- Alcohol: Detected in approximately 50% of the mummies.
- Harmine: A hallucinogenic compound found in several remains.
This chemical evidence is bolstered by archaeological finds at sites like Llullaillaco and Ampato, where male figurines feature cheek bulges that experts believe represent the chewing of coca pulp. The presence of vessels containing these drinks buried alongside the children further supports the theory of a multi-substance ritual approach.
A six-month chemical shift for the Chuscha girl
Forensic reconstruction of the children's final months provides a granular look at how these riutals were staged . For one eight-year-old girl from Chuscha, the toxicological data revealed a progressive change in her physiological state. Researchers identified a consistent pattern of coca consumption over a six-month period leading up to her death, but alcohol traces only appeared during her final month.
This timeline suggests that the Inca did not simply administer substances at the moment of sacrifice. Instead, as Katarzyna Socha, the study's lead bioarchaeologist, noted, the preparation was not uniform and likely involved altering the child's state of consciousness in stages as the ritual date approached.
Imperial authority and the Cusco-led religious system
These sacrificial rites served a vital political function for the Inca Empire by reinforcing the state's connection to the divine.. The ceremonies were often triggered by environmental or social crises, such as droughts, famines, or political instability, which threatened the cosmic order. By conducting these rituals, the Inca state could integrate regional deities into their own imperial religious framework.
The selection of children for these sanctified roles occurred across the vast empire, with ceremonies taking place at the capital in Cusco or at various provincial oracles and temples. This practice allowed the central government to establish and maintain deep religious and political ties with local communities throughout their territory.
Uncertainties in the specific dosages at Llullaillaco
While modern forensic toxicology has corrected several historical misconceptions, significant gaps in the narrative remain. Although the study successfully identified the presence of substances, it remains unclear what the exact dosages or concentrations were for each individual ritual.. Furthermore, while the research highlights that preparations were not uniform,the specific reasons for why one region might favor alcohol while another favored harmine are not yet fully understood.
The researchers have not yet determined if the variations in substance use were dictated by the specific deity being appeased or by the local traditions of the provinces where the sacrifices occurred. As the team plans to revisit other aspects of Inca religious practices, these questions regarding the precise "cocktail" used at sites like Llullaillaco remain central to the investigation.
