Juan Carlos G Mantilla is an Ecuadorian PhD candidate at Columbia University in the Department of Latin American and Iberian Cultures, the Institute of Comparative Literature and Society, and the Medieval and Renaissance Studies Program. His research focuses on the cultural history of the early modern Americas. Bringing together literary studies, art history, archaeology, and sources in Romance, classical, and Indigenous languages, his doctoral project entitled “Repleta est Terra: World Landscapes and Chronologies of Early Modern Andean Historical Cosmography” studies how in the early modern period, Indigenous pre-Columbian material culture and narrative traditions transformed into sources for novel global cosmographical theories, world historical narratives, and scholarly innovations. In 2021, he was a doctoral fellow in Freie Universitat Berlin’s EXC 2020 “Temporal Communities,” and in 2022, a Social Science Research Council’s International Dissertation Research Fellow.
