Inka Ritual Uncovered: Coca Leaves Found on Sacrificed Llamas
Archaeologists discover coca leaves stuck in the wool of sacrificed llamas at Tambo Viejo in Peru, contradicting previous reports from Spanish chroniclers

Archaeologists have made a significant discovery at the Inka provincial center of Tambo Viejo in Peru, uncovering coca leaves stuck in the wool of sacrificed llamas. This finding provides the first direct evidence of coca use in rituals at the site.
The discovery was made during excavations in 2024, specifically at Structure 4, where three sacrificed llamas were found with coca leaves stuck in their wool. This finding is notable, as it contradicts previous reports from Spanish chroniclers that coca was burned or bundled up during ritual offerings.
Tambo Viejo, located in Peru's Acarí Valley, has been the subject of ongoing excavations since 2018. The site, founded in the early 1400s, has yielded a range of significant discoveries, including tasseled sacrificial llamas and brightly adorned guinea pigs.
The Inka people believed that the world was filled with spirits that needed ritual offerings in return for good favor. Coca was considered a sacred plant and was used in almost every single ritual activity. The discovery of coca leaves at Tambo Viejo provides valuable insight into the rituals and practices of the Inka people.
## Why it matters The discovery of coca leaves at Tambo Viejo is significant, as it provides a unique glimpse into the rituals and practices of the Inka people. The finding also highlights the importance of preserving archaeological sites, as the dry climate of Tambo Viejo has allowed for the preservation of fragile plants like coca leaves. This discovery will likely contribute to a greater understanding of Inka culture and rituals, and will be of interest to historians and archaeologists studying the region.
The excavation of Tambo Viejo is ongoing, and it is likely that further discoveries will be made in the future. The site's unique preservation conditions make it an important location for archaeological research, and the discovery of coca leaves is a significant addition to our understanding of Inka rituals and practices.
