The purpose of this article is to undertake a reading of Gracia y el forastero, a novel by Guillermo Blanco (1926-2010), helped by the notion of mimesis that Paul Ricoeur offers for the narrative works. Ricoeur develops a triple mimesis of the narrative experience that covers the world of the reader and of the story. The experience begins before the first moment of reading, passes through the reading itself, and later returns back to the world of the reader, weighing up the contribution of story reading. However, the experience of the mimesis is approached here in the case of Gabriel Romero the reader, who is the main character and narrator of the novel, and also, as a narrator, the reader of the developing story. The world of story is, for us, the world of Gabriel, narrator-reader of himself. It interests us to determine the transformation that he experiences by the story assumed for him: how he lives the triple mimesis. We so conclude that Gabriel gains a new self-image, richer, more complex, perhaps more tensioned; whose development gets strong by that narrative identity, according to Ricoeur. Finally, the I gains a better self-comprehension by setting himself as the object of a story which puts him out of, and turns back to himself.
