The paper examines diverse modalities of the myth related to the figure of Narkissos as represented in the French literature related to the aesthetical movement commonly called fin-de-siècle, mainly their functions in the writings of Andr é Gide and Paul Valéry in the view of past representations ("mythèmes") which were to participate as constituant of its nucleus in the works by Gourmont, Rodenbach and Jean Lorrain. The psychoanalytical and mythocritical approach make clear the affinities between the symbolical meanings of the related myth and the aesthetics fin-de-siècle.
