Abstract
In this article, the author offers a panorama of the narrative work of Juan Agustín Morfi, a Franciscan friar with a vast culture, not only theological, but with an evident desire of cultivating the historical memory of the Mexican northem border near the end of the 18th century. Through his extensive work, father Morfi leaves behind evidence of the processes of exploration, evangelization and colonization of the New Hispanic Septentrion, in which he and other Franciscan friars intervened. Thus, with documents such as the Memorias para la historia de la provincia de Texas or the Descripción geográfica del Nuevo México. Año de 1782, Juan Agustín Morfi shows himself as a pioneer of the former history of our northem border, that at the time went all as far as New Mexico, Texas, Nuevo León, Tamaulipas, Coahuila and California.
