Féerie, sometimes translated as "fairy play", was a French theatrical genre known for fantasy plots and spectacular visuals, including lavish scenery and mechanically worked stage effects. Féeries blended music, dancing, pantomime, and acrobatics, as well as magical transformations created by designers and stage technicians, to tell stories with clearly defined melodrama-like morality and an extensive use of supernatural elements. The genre developed in the early 19th century and became immensely popular in France throughout the nineteenth century, influencing the development of burlesque, musical comedy and film.
