This thesis investigates the aesthetic trajectory of Luiz Ruffato's literary project that is inscribed under the rubric of Provisional Inferno. In search of a novelistic composition that inserts him in a revolutionary way in the context of contemporary Brazilian literature, Luiz Ruffato embarks on his literary project when publishing the work Histories of remorse and rancor (1998). Continuing it with (the survivors) (2000), the writer reaches the series of five volumes that are interconnected by the rubric Provisório Inferno. In 2016, the novelist's romanesque project culminates, then, in the single volume work entitled Inferno Provisório. Taking the eight works as the corpus of analysis of this investigation, I infer that Luiz Ruffato's artistic-literary creation is based on what I call ‘palimpsychic aesthetics’. His humble origins, his experiences in the world of work, linked from an early age to the habit of reading corroborated the intellectual and critical training required of a literature writer. With an apparently defined literary content, Luiz Ruffato had faced a relatively common concern to the literate, that of ‘how’ to write. From this concern, a concern arises that makes him revisit the works that make up his literary project and put them back in tension. In the pursuit of this tension, I seek to ascertain an aesthetic that is shaped by dissatisfaction with its own finish. Aesthetics that finds in the image of the palimpsest a metaphor capable of showing both the successive inscriptions of the project Inferno Provisório, and the effect of transparency in their respective updates.
