Aquilino Ribeiro and João Guimarães Rosa are among the most important writers in Portuguese and Brazilian Literature of 20th century. They have been often compared each other for their baroque and expressionist prose, and because of the mostly rural and regional setting of their major works, usually classifying them as Literary Regionalism. The present study aims to analyze, through significant examples, the relationships and similarities between these writers, highlighting all the centrifugal forces that (through a Bakhtinian point of view) work in contrast to the standardized literary language.
