The aim of this work is to analyze the poetics of spaces in the novel Pretérito perfecto (1983), created by the argentinian writer Hugo Foguet (1923-1985). Starting from this main idea, we are going to distinguish the designs of interior and public spaces, which constitute the plot, and reveal multiple and yuxtaposed temporalities. The novel connects the family narrative and configures the imagery of a peripheral nation. The telling of the history about a provincial city cannot be torn apart from an aristocratic lineage which is in decadence.
