The narratives by Teixeira de Sousa (1919-2006) are part of the Claridade and Certeza movements, particularly in what concerns their proposed reading of historicity. These two movements clearly exemplify Realism in Cape Verde, and they voice national identity and the (re) discovery of Cape Verdean reality. One should note as well the presence of an aesthetics affiliated to the political and ideological positions of Portuguese Neo-realism. The focus of this dissertation is the analysis of Teixeira de Sousa’s narratives (short stories and two trilogies of novels). We elaborate on the extension of the above-referred topics for the representation of socio-historical and cultural phenomena as well as on their interaction with two insular microcosms in different colonial and postcolonial periods. In the first trilogy we refer to the universe of Fogo island; the decadence of the ruling class, the social differences, migration, identity. In the second case, we discuss the urban reality of the island of S. Vicente, framed by the sea, the docks, and the ethnic and cultural diversity. We also consider the emergence of national sovereignty, literary creation, and human essence in general in these writings. This dissertation deals as well with the discussion of realist and neorealist enunciation, through the author’s particular style.
