The recovery of memory and testimony has become a vital requirement after the most brutal Argentine military dictatorship that took place between 1976 and 1983. Hauled historical trauma and deep wounds, individual and collective, resulted in numerous cultural events. We intend to analyze two different ways, within the dramaturgy of the post- dictatorship, narrate the question of re- pression and desaparecidos, like the paradigms of a whole trend of texts which the theatre as an instrument of political and social inquiry is considered. The work of Lola Arias calls for referential and ex- plicit language -their own political thea- ter- even though it contains an important symbolic sense. While the texts of Omar Pacheco manifest the crisis of the tradi- tional dramatic narration and the notion of semantics, and restrictive that it considers the word only in its psychological dimen- sion to instead highlight its materiality and its opacity means.
