摘要:This paper analyses the relationship between the fictional and factual discourse in the Spanish American narrative of the nineteenth century. This analysis considers that both discourses establish a close relationship inside the texts that have been seen as part of science fiction literature, as well as in those classified as essayistic. From this perspective, it opens up the possibility of analyzing those works in narrative terms that have historically been placed in between the historiographical critique and the literary critic. The proposed analysis suggests the study of two texts: El Periquillo Sarniento (1816), by José Joaquín Fernández de Lizardi, and Mariluán (1862), by Alberto Blest Gana.
