Abstract: This study proposes a rereading of Fragments d’un paradis and Noé, novels by Jean Giono published after the Second World War, in the light of Isidore Ducasse’s work. It explores, on the one hand, the intertextual links that unite them and, on the other hand, the mentions of Lautréamont in Jean Giono’s diary, his preparatory notebooks, and his correspondence.
