This work examines the hermeneutic work of theater directors as artists, a rarely considered aspect of contemporary theater in Argentina. It is in Spanish. The work analyzes different mise-en-scene aesthetics used by Argentinean theater directors at the end of the twentieth-century. The study demonstrates that there is not an aesthetic form that could be considered as dominant, but rather exist a plurality of methodologies for theater direction in Buenos Aires. When analyzing the mise-en-scene in the Argentina of the nineties, the interrelation of the theater with the culture of this country, the function of the director, the realistic and theatralistic mise-en-scene, and its transition to the emergence of postmodern theater in Buenos Aires are considered. The diversity of the existing strategies and direction methods used in Buenos Aires are studied within a democratic sociopolitical process. The different aesthetics that develop in Argentina from the 1980s, after the last military dictatorship (1976-1983), and that begin to consolidate in the 1990s, constitutes a historical phenomenon of singular importance.
