[5] 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.
"[2] Mellerio's papers, which include a great deal of biographical information about Redon, are now in the Ryerson and Burnham Archives at the Art Institute of Chicago, who purchased them from a dealer in 1991.
[3] Mellerio, with Noël Clément-Janin, was the editor in chief of L'Estampe et l'Affiche, an illustrated art magazine (Paris, 1897-1899).
