Pierre Puvis de Chavannes
Mellerio elaborated the rise of "idealist art" in "Le Mouvement idéaliste en peinture", published in Paris in 1896. He traced the emergence of the form to the "Exposition des Peintres du Groupe Impressionniste et Synthétiste" of the Pont-Aven group at the Café Volpini in Paris, 1889, and attributed its origins to Gustave Moreau, Paul Gauguin, Pierre Puvis de Chavannes and Odilon Redon.
