This article is about the relation between history and literature in a specific historical novel, Marco Zero, written by Oswald de Andrade in the first half of 1940. Discussing the concept of historical novel and what João Alexandre Barbosa defined as "interval reading" - in which the literary discourse is understood as a way to produce knowledge, and not only as a reflection of it - I tried to comprehend how Oswald builds his narrative - creating a historical context and interpreting it -, how he works with categories such as space and time and establishes relations among his diverse and numerous characters. Oswald's writing is close to the concept of historical novel defined by Marilene Weinhardt, as he works on the limitations of the hegemonic historical discourse. So, analyzing aspects that were ignored by the critics of Oswald's books, that commonly considered Marco Zero a defective novel and/or a creative decline in Oswald's career, this article offers the chance to consider the Oswaldian's novel as a topic of historical discussion, paying attention to the different uses of history made by varied discourses that are in society.
