Based on the analysis of self-translation done by Álvaro Cunqueiro, a recognized author in both Galician and Spanish literature, possible implications of endogenous bilingualism in self-translation are studied. One observes increased tension between the trend of literal and literacy preservation of heterolingualism and the desire to be accepted in the target language. These two competing forces, taken to the extreme by an author-translator freed from the spectre of invisibility, ultimately offer an excessively heterogeneous text, marked by expository strategies of a diverse nature which, at the same time, clearly show the “unique” voice of the self-translator as a second interlocutor.
