Aiming at the study of the novel O Delfim, this dissertation lines off the singularity of Jose Cardoso Pires` fictional creation that with its impact on the reader, works as a conductor of the imaginary, yet raising awareness of the reader’s surrounding reality. While treating the existing proximity between both, based on the studies of Wolfgang Iser, my goal is the identification of the role of the imaginary and the fictional texts in the forming of societies and the construction of reality. This work presents an analogy between the reading process and the textual creation as well as the renewal of the imaginary as a fundamental part of reality. Such analogy is then compared with the fiction of José Cardoso Pires. In the creation process of this novel, the prominent position granted by the author to the narrator as well as to the ideal reader and the recreation of the literary styles are easily noticed. These are nothing but writing mechanisms to create building perspectives of reality through literary representation.
