A invenção de Bispo do Rosario, by potentializing possible senses of the word invention, evokes the creative act and the discovery, as operations of the author and the reader (receiver), simultaneously. By this way, Bispo do Rosario is seen as an inventor and as an object of invention. In the scope of the object of invention, are projected the adventure of the discovery and of the translation of his world, engendered by the filter of the reading, not only as an other text, but as an other reality, emphasizing the conception of the deed as surface of alteration. This work is organized in three tomes: the first one relates to the invention of a fictional place, in which occurs the encounter of Arthur Bispo do Rosario, Antonin Artaud - who is visited by the theoretical approach of some important questions - and Cecilia, the blind. The encounter of these three characters, considering the theatrical performance, will put into play subjects like representation, authority of language and creative potence. The second one tells the history of the invention of Arthur Bispo do Rosario as an artist, introduced in the sphere of the Fine Arts by the critic and art historian Frederico Morais. The trajectory to legitimate Bispo as an artist is considered through the analysis of press publications together with some interviews, which were realized specifically to focus the strategic points awoken by the reading of the selected materials. In the last tome, Arthur Bispo do Rosario is apprehended as an inventor of a expressive universe, in the perspective of my analysis, stressing, in this way, the irrevocable mark of the writing as an invention.
