Giselle (French: Giselle ou les Wilis) is a ballet in two acts with a libretto by Jules-Henri Vernoy de Saint-Georges and Théophile Gautier, music by Adolphe Adam, and choreography by Jean Coralli and Jules Perrot. The librettist took his inspiration from a poem by Heinrich Heine. The ballet tells the story of a peasant girl named Giselle whose ghost, after her premature death, protects her lover from the vengeance of a group of evil female spirits called Wilis (a type of Slavic fairy also spelled Vila, Wila, Wiła, Veela). Giselle was first presented by the Ballet du Théâtre de l’Académie Royale de Musique at the Salle Le Peletier in Paris, France, on 28 June 1841. The choreography in modern productions generally derives from the revivals of Marius Petipa for the Imperial Russian Ballet (1884, 1899, 1903).
The pervasive atmosphere of the ballet was indebted to the works of Victor Hugo, Heinrich Heine, and the ballet critic Théophile Gautier. The librettist Verney de Saint-Georges had first been attracted to Hugo’s Orientales with its evocation of a ballroom where dancers were condemned to dance all night, and to Heine’s De l’Allemagne and its depiction of the Wilis, Slavonic supernatural beings who lured young men to death by dancing. The notion may have been based on St. Vitus’s dance, the dancing mania of the Middle Ages.
