“Coca says that the hill fell out of jealousy”: testimonies about a threatened practice and episteme in Ancash, Peru

Purpose This study aims to promote the preservation of endangered traditional knowledge and practices in the Andes of Peru by documenting, publishing and disseminating them. Design/methodology/approach Based on a literature review of coca and coca divination, the author will describe these types of divination practices. Subsequently, the author will address the context and characteristics of a coca reading conducted in October 2022. Afterwards, the threats and prejudices faced by this type of indigenous knowledge and practice are discussed. Findings Coca divination in the Andean region of Ancash differs from the most common form of divination with coca leaves performed in northern Argentina, Bolivia, northern Chile, Colombia and southern Peru. The results of the coca reading conducted in October 2022 align with Andean worldviews. These practices and the associated episteme face various threats from academic, social and political actors and their discourses. Practical implications Scientific and academic researchers should be aware that their work can foster and maintain epistemic colonialism in Latin American territories. Archaeological excavations and interpretations should respect ancestral and traditional worldviews and practices. Originality/value This study advances the understanding of coca divination in the Andes of Ancash, Peru, by providing nuanced insights into this cultural practice in relation to a landslide event that occurred near a 3,000-year-old temple. The implications extend beyond academic discourse, offering valuable perspectives for conducting archaeological excavation activities that respect ancestral and traditional local beliefs. Future research should build on these findings to deepen comprehension of threats to traditional beliefs and practices.
