Under Guimarães Rosas Tapatrava: the mysticism in Joãozitos life and literature, is an attempt to, based on his private notebooks, letters, interviews and friends and familys testimonies, prove how important mysticism was in Guimarães Rosas life and how this has influenced his way of perceiving and writing literature. Based on biographic texts, reading indications found in his private library and the revelations done by the author himself, this project tries to change the idea that the mysticism was only used as an intertextual resource and prove that it was a personal belief conveyed in his literature. The way this rosian literature is made is also discussed in this essay, presenting its relation to mystic intuition and a pre-babelian alchemical language, very much like Walter Benjamins adamitic language.
