This thesis questions the representation of the hero by the realist and naturalist movements of the XIXth century. Transgressing six novels and short stories, it aims at highlighting the inherent tension of the heroic figure in the works of Honoré de Balzac, Gustave Flaubert, Guy de Maupassant and Émile Zola. Despite an apparent refusal of the classic antique model which is illustrated by a trivialization of the main character, the realist-naturalist novelists do not escape from the heroic temptation; by offering a journey of initiation and unusual forms of sacralization, they fabricate a new type of hero, both closer to the concerns of society at that era and influenced by mythical and eternal representations (whether from mythological, biblical, literary, psychoanalytical or religious fields). The dialectic between the societal temporality and the permanence of the legendary is thus to be read. This doctorate thesis therefore seeks to de! monstrate the immutable execution of a heroic symphony within the realist and naturalist poetry while recalling the specific nature of the hero in the work of each author studied
