“Wagner was one of the masters of Symbolism; his conception of art, his philosophy, his very formula were at the origin of Symbolism. It was impossible to get to the bottom of Wagnerism without encountering Symbolism; that is to say, it was impossible to expound the Wagnerian conception without recognizing in it the doctrine, or at least one of the primordial elements of the new poetic doctrine.”

Édouard Dujardin, 1936
