The literary writing of Silviano Santiago questions the conception of modern literature, problematizes the literary making from a meta theoric perspective and makes use of an enunciating voice in the first person speech, that unfolds continuously in the literary tissue. The selected works for the corpus of the thesis – Stella Manhattan, Uma história de família, O falso mentiroso e Histórias mal contadas – present an wavering enunciate that organizes itself through the unfolding of the narrative voice in a fictional self, delineated from the alternation between the projection of the writer s biographic references and the projection of his critic-theoric speech. The selected corpus makes relative the subject representation and erects the discursive enunciate at the same time that theorizes about the enunciation process by means of the wavering narrator. In face of this new perspective of the literary making, the study, conscious that new reading strategies have become essential, broadens its analytical field, extending a look into the extraliterary speech of the interviews, conceded by the writer to ratify his essay line of thought and to propose a reorganization of the fictional frontiers.
