In this seminar, we will dive into the reports and letters of missionaries who left testimonies related to the Jesuit Provinces of Peru (1568), the New Kingdom of Granada (1611, 1696), Quito (1696), and others. We will oscillate between texts, drawings and other mediums of representation as we speculate about the spatialities of the Jesuit missions through the window of these early colonial documents. Our main objective will be to understand how the spatial paradigms of the castrum, the City of the Sun, and Renaissance ideals became hybridized with vernacular Indigenous architectures and spatial planning in the syncretic Missions of Mojos and Chiquitos, the Guaraní territories, California, Florida, Chiloé, the Araucanía, and most importantly, in Maynas. This will include the agricultural and livestock paradigms characteristic of Europe and the polycultural agroforestries that embody Amazonian cosmologies. An overview of Jesuit syncretic architecture, agriculture, and planning will allow us to illustrate to the best of our ability the Maynas Mission, whose visual history will be included in an exhibition to be inaugurated in April of 2026 in the Metropolitan Cultural Center (Centro Cultural Metropolitano, CCM) of the city of Quito.
