The impressionism is not only a painting movement. Painters share with writers, musicians, and sometimes filmmakers, the same motifs.
But everyone has its effects related to his art, and sometimes appears a synesthesia when Mallarmé, Manet, Debussy and Nijinsky interact or when Degas share the same stage with Maupassant and Meyerbeer.
This is the thread of Les Guides MAF, in other words :
Perfumes, colours and sounds respond to each other
Baudelaire: Fleurs du Mal
