This article analyzes the novel Em breve cárcere, by Sylvia Molloy, focusing on the reading and writing scenes that configure fragmentary autobiographical experiences, here understood as autobiographemes, a concept derived from the idea of “biographeme” proposed by Barthes. Writing emerges as an attempt at subjective elaboration, in which the narrator seeks to access both her interiority and the other. Based on the concept of obliqueness, discussed by Wisnik, the article examines how the self is constituted in relation to the other, and how this tension permeates the text. Marked by uncertainties, lapses and inventions, writing presents itself as a process of search and resistance in the face of the impossibility of fully grasping memory.
