In this essay I offer a reading of Hijo de ladron from its intertextuality with masonic discourse. In addition to the edited novel and the manuscript from 1950, the corpus includes records of the Masonic meetings in which Rojas participated, as well as unpublished and little known texts by the author. My thesis is that Rojas turns to Masonic symbolism and anthropology to rethink the concepts of subject and community in the novel. Considering the initiation ritual and the spatiality of the lodge, I reflect on a battery of symbols that strongly influence the representation of Aniceto's life path and the human groups which he is part of. In the development I discuss the relationships of these symbols with others of an anarchist nature.
