Coppélia (sometimes subtitled: La Fille aux Yeux d'Émail (The Girl with the Enamel Eyes)) is a comic ballet from 1870 originally choreographed by Arthur Saint-Léon to the music of Léo Delibes, with libretto by Charles-Louis-Étienne Nuitter. Nuitter's libretto and mise-en-scène was based upon E. T. A. Hoffmann's short story Der Sandmann (The Sandman). In Greek, κοπέλα (or κοπελιά in some dialects) means young woman. Coppélia premiered on 25 May 1870 at the Théâtre Impérial de l'Opéra, with the 16-year-old Giuseppina Bozzacchi in the principal role of Swanhilda and ballerina Eugénie Fiocre playing the part of Frantz en travesti. The costumes were designed by Paul Lormier and Alfred Albert, the scenery by Charles-Antoine Cambon (Act I, scene 1; Act II, scene 1), and Édouard Desplechin and Jean-Baptiste Lavastre (Act I, scene 2). The ballet's first flush of success was interrupted by the Franco-Prussian War and the siege of Paris (which also led to the early death of Giuseppina Bozzacchi, on her 17th birthday), but eventually it became the most-performed ballet at the Opéra. Modern-day productions are traditionally derived from the revivals staged by Marius Petipa for the Imperial Ballet of St. Petersburg in the late 19th century. Petipa's choreography was documented in the Stepanov method of choreographic notation at the turn of the 20th century. These notations were later used to stage the St. Petersburg version for such companies as the Vic-Wells Ballet (precursor of today's Royal Ballet). Plot Dr. Coppélius is a doctor who has made a life-size dancing doll. It is so lifelike that Franz, a village youth, becomes infatuated with it and sets aside his heart's true desire, Swanhilda. She shows him his folly by dressing as the doll, pretending to make it come to life and ultimately saving him from an untimely end at the hands of the inventor. Act I The story begins during a town festival to celebrate the arrival of a new bell. The town crier announces that, when it arrives, anyone who becomes married will be awarded a special gift of money. Swanhilda and Franz plan to marry during the festival. However, Swanhilda becomes unhappy with Franz because he seems to be paying more attention to a girl named Coppélia, who sits motionless on the balcony of a nearby house. The house belongs to a mysterious and faintly diabolical inventor, Doctor Coppélius. Although Coppélia spends all of her time sitting motionless and reading,
