The study is divided into three parts. The first discusses the common features of both poets: their lartpourlartism and opposition to the utilitarian conceptions of art.
The second part focuses on a romantic iconology (sacrifice of the poet, its figures and symbols) used by Ch. Baudelaire and T.
Gautier to represent a role of poetry as well as tragic situations of the contemporary subjects. The last part analyses some transformations in the Baudelaire's poetics through the mediation of the concepts of modernity, every day, singularity and reversibility.
