Les Sylphides
During these years, his work with Diaghilev's Ballets Russes was groundbreaking. His sets and costumes for the productions of "Les Sylphides" (1909), "Giselle" (1910), and "Petrushka" (1911), are counted among his greatest triumphs. Although Benois worked primarily with the Ballets Russes, he also collaborated with the Moscow Art Theatre and other notable theatres of Europe.
