The aim of this work is the configuration of a constellation of delirious fictions in contemporaneous Latin American Literature, from the conceptualization of literary delirium and the analysis of the process of construction of the delirious story. Since some Latin American narrators display delirious fictions today, we propose an analysis of the pertinence of a wide number of cases where delirium is evidenced as a literary fact. Such phenomenon is confirmed in authors like Mario Bellatin, Roberto Bolano, Rita Indiana Hernandez, Horacio Castellanos Moya, Cristina Rivera Garza, among others. Therefore, our main focus will be the creation of a critical base for the interpretation of the delirium of some characters of contemporaneous Latin American Literature, as a cultural construct that transgresses the social order, being assumed as a resistance and articulation of a creative praxis.
