He is known for his collections of poems in which he showed a perfect mastery of prosody, a perfection of form, a wealth of inspiration and emotion: L'Enivrante Angoisse, La Tempête, La Chanson des Deux Jeunes Filles or Perséphone.
It is undoubtedly his Le Bestiaire sentimental which popularized him with the general public after the war and which comprises three volumes: Vie de Grillon, La Chauve-Souris and Émile et les autres.
