The novel of Claude Simon dialogues with many texts through various composition procedures, especially due to the explicit intertextuality in many cases. In the aesthetic context of the nouveau roman, the French "new novel", the author deals in his writing with peculiar linguistic aspects, including the time perspective, which demonstrate its literary character. Thus, there is a clear need to the critics to understand how the various text organizational principles articulate among themselves in favor of a unit, made of fragments that stick and deform according to the demands of the writer, being thus a kind of palimpsest. The Latin intertext, the relationship between a text and the ancient Roman literature, plays a key role in the creation of the Simonian text, which also interferes in our reading of other elements that interact with it. One of the novels which sets out clearly that intertextual factor in Simon's literature is La Bataille de Pharsale (1969), our option for object of study, given the rise of problems posed by the presence of classical culture in the work by relations and transformations. In this novel, the war is one of the main points derived from the relations between ancient and modern in writing, so that other compositional aspects of the text, as time and enunciation, seem to establish a reciprocal interference with the intertext. Taking into account these factors, our analysis had the aim of reassessing the critical path on the author's work in a comparative and multidisciplinary approach to provide relevant conclusions about our object. From this study, we provide reading possibilities for the novel based on our discussion, as well as new perspectives for the understanding of Claude Simon's work and the modern novel in relation to the classical tradition.
