Diario de la expedicion reduccional del ano 1780, mandada practicar por orden del Virey de Buenos Aires
by Francisco Gavino de Arias
About the author
Best known as the author of Diario de la expedición reduccional del año 1780, he was a soldier and explorer active in the Río de la Plata region during the late colonial period. Library and public-domain catalog records connect his name with that expedition diary, which has survived as his principal known work.
Reference sources are not fully consistent about his life dates: some cataloging records give an uncertain death date, while other reference pages identify him as having died in 1808. What can be said with confidence is that he is associated with Salta and with a 1780 campaign ordered from Buenos Aires, and that his diary is valued today as a historical account of the Gran Chaco frontier.
For readers interested in early South American history, his work stands out less as polished literature than as vivid documentary writing. It preserves the language and concerns of a colonial officer on expedition, making it useful both as a historical source and as a window into the world he moved through.
