Paris, 1910-1915. Artists, intellectuals, and international celebrities crowd the city as never before. Decadent dreams and avant-garde manifestos celebrate the marriage between art and life. Creative experiments and vital joy dance hand in hand ?on the edge of the abyss of WWI. Gabriele D ?Annunzio is one of the highly influential yet semi-forgotten protagonists of this season and an emblem of its contradictions. A child of the Decadence, but also a forerunner of Modernism, the Italian poet defies the barriers between art forms, languages, and aesthetic practices. Tellingly, some of the period ?s major figures across the arts are involved in D ?Annunzio ?s projects, including Canudo, Bakst, Brooks, Debussy, Montesquiou, and Rubinstein. In particular, in his sacred drama Le Martyre de Saint S©?bastien , the poet combines French, Italian, literature, theater, mime, dance, music, painting, and cinema in a way that fuses old and new. D ?Annunzio ?s hybrid experiments challenge Wagner ?s ?total artwork ? theories, search for a synthesis between pictorial stillness and filmic movement, and anticipate contemporary multimedia experiences. These artistic collaborations end suddenly at the outbreak of the Great War, when Dannunzian total artworks migrate from the stage to the battlefield, generating a controversial legacy that calls for renewed critical investigations.
