An obscure occult artist even among catalogues of obscure occult artists, Julien Champagne (also listed as Jean-Julian) is known principally for his associations with the persistently elusive 20th century alchemist Fulcanelli. Champagne provided a frontispiece (below) for Fulcanelli’s examination of architectural symbolism, Le Mystère des Cathédrales (1926), and is continually rumoured to have been Fulcanelli himself. Whatever the solution to that mystery, the alchemist’s book is rather more visible than the artist’s distinctly Symbolist paintings. There’s a French blog devoted to his life and works here but little else around. I wouldn’t mind seeing a decent online gallery of his pictures at some point.
