The essay performs a reading of the poem “Autobiogeografia” by Fernanda Vieira, highlighting the act of literary creation as an element that inaugurates a space of identity (re)foundation, marked by the process of decolonization of subjectivity and the claim of ancestral heritage. Emphasis will be given to the characteristics of a writing-praxis (Olivieri-Godet, 2000) through which the affirmation of ethnic identity in the literary landscape is carried out. The theoretical basis essentially resorts to the concepts of decoloniality (Mignolo, 2010; 2015), coloniality of power (Quijano, 2007; 2015) and transgenerational memory (Bernd, 2018).
