Abstract: Claude Simon, fatherless, then motherless, had no real family. Throughout his work he strove to recreate it, or rather to create it. The Proustian narrative was a model in this regard, which he nevertheless undertook to deconstruct in order to succeed in building his own family universe. It is the twists and turns of this problematic strategy that are studied, in order to understand the multiple variations of tonality that characterize the Simonian work.
