Abstract
This essay presents the articulation established between two researches: one of an artist and professor of printmaking and the other of my master's and doctorate. The first is dedicated to the proofs of state, to the interpretation of chance and senses, of what has been substracted and or added (of what is lost and what is gained) to the printed image mediated by the matrix that had led it. The second, in an analogous way, takes the printed book as a matrix that reproduces writting and which, mediated by it, may also have something that is subtracted or added to it. The hypothesis of João Guimarães Rosa that “the book might be worth as much as what did not fit in it”, presented at the end of the preface Aletria and Hermeneutics, from the book Tutaméia: third stories, runs through both researches and meets at Para-Luz Library, a work that, with its empty books, untied and stacked, shelters and unshelters images of the emptiness of the world in the world of the book.
