The four Emperors: the composer Igor Stravinsky, the choreographer George Balanchine, the painter Henri Matisse and the entrepreneur Serge de Diaghilev. The Nightingale: the English ballerina Dame Alicia Markova who danced the role of the nightingale in 1925 in Monte-Carlo and Paris, when she was 14 years old. The lost ballet: Le Chant du Rossignol, based on a fairytale of Andersen, created in 1925, and reconstructed in 1999 by two English dancers Millicent Hodson and Kenneth Archer. (Fipa)
