The thesis The word-landscape and the tensions of the colonial library: a study on the cosmogonies of the writing of Ruy Duarte de Carvalho aims to investigate the literary production of the Angolan writer and intellectual Ruy Duarte de Carvalho, considering the nuances of the landscape embodied and the impasses of crossing the western library in order to facing the emanations of a global civilizing system. These nuances are analysis matrices of, respectively, the last two volumes of the trilogy Os filhos de Próspero: As paisagens propícias (2005) and A terceira metade (2009). Duarte s half-fiction writings are constructed before the eyes of the reader, in other words, the author-narrator depictures the writing process, based on literary and narrative procedures that theorize and reference his own work. While the stories of the self, intertwined and confused with the other (main character), play with moving landscapes, due to the trip, with the I-narrator and with the other, as much the other considered only the different from the self (as the borders characters protagonists of the trilogy Os filhos de Próspero) as the other distinguished by the author in theoretical texts as traditional societies that did not have their customs and cosmovision totally modified by colonialism. Thenceforward, the research emerges questions in relation to why and how the relational triangle I-other-space contributes to other meanings in the works of Ruy Duarte de Carvalho. Can landscapes indicate the cosmovision of this Other? How to think about the post-colonial from an European experience in fiction? After the path of methodological deviations of the research and the close reading of the two novels and other works of the author, on the one hand, the word-landscape somehow differs from the theories of geography and philosophy about the landscape, since that one can apprehend epistemic landscapes arising from pastoral worldviews interfered with by Western epistemes. On the other hand, and in a similar way, there seems to be a dispute over the meanings of science through an epistemological polyphony, in which a blunting of western science and the colonial library appears, which mixes with the theories of pastoral cosmogonies depicturing by the main characters, Severo and Trindade. The question of power and the angles on which the gaze rests crosses the two approaches in both the epistemology of the landscape and the knowledge. As a result, the novels have complex plots that undo dichotomies through heterogeneous worldviews, in a literary and poetic game of otherness that turns to interlocution rather than representation.
