In 1965, the filmmaker Jorge Prelorán began to develop a vast documentary series, entitled Relevamiento Cinematográfico de Expresiones Folklóricas Argentinas, dedicated to the study and filming of inlands regions of the country. The project, which was sponsored by Universidad Nacional de Tucumán and Fondo Nacional de las Artes, took place in the midst of an intellectual and artistic context marked both by the emergence of diverse proposals for the renewal of cinematographic language, and by the cultural phenomenon known as boom of the folk movement, which occurred in the 1960s in Argentina. Therefore, the purpose of this thesis was to investigate how Jorge Prelorán reformulated, in the films he made for the project between 1965 and 1975, a set of themes, topics, methodologies, narrative resources and discursive procedures originated from three broad domains, with which the director maintained close contacts: the long tradition of Argentine essays, dedicated to the interpretation of the nation; the fields of folklore and anthropology prevailing in the country, in its multiple phases; and the modalities of ethnographic cinema with which the director related in those years. The dialogues that were established between Prelorán s work and the intellectual and artistic traditions mentioned previously – dialogues that were almost always based on the strategies of describing nature, on the different modes of representing time and space and on the models of depicting art and culture used by the filmaker – were conceived throughout this research as variations around four major themes: cartography, travel, compendium and empathic filming methodology.
