The article starts with a group of four short-stories ("Um músico extraordinário", "Um que vendeu a sua alma", "Dentes negros e cabelos azuis") penned by Lima Barreto featuring a friend of the narrator as a protagonist. The formal and semantic analysis of this body of texts shows progressive fictionalization of Lima Barreto as a representative of a double exclusion and points out the role of the fantastic in the transition of the biographic to the social.
At a superior level, the analysis contributes to the reflection of the dilemmas and internal divisions brought by the modernity of Brazilian Belle Époque.
