Self-fiction The confession of Lúcio, by Mário de Sá-Carneiro, is a narrative in which the character Lúcio, a Portuguese writer, confesses, after ten years in prison, that he had not committed the crime for which he was paying. Faced with the question of what would be the commitment of the arts in the representation of time and space in the self-fiction of Mário de Sá-Carneiro, this article aims to associate the Bakhtinian chronotope with the mist metaphor, a symbolic form we created to analyze how the modernist and sensationalist writer built sensations, reflections of the characters, and actions from the images provided by the Parisian arts, combining time and space with daydreaming imagery. The methodological reflection will be restricted to the analysis of the moments/dia- logues in which the artists talk about themselves, the sensations, and the arts.
