This is the first collection of essays to explore the wide dimensions and influence of eighteenth-century opera. In a series of fresh articles by leading scholars in the field, new perspectives are offered on the important figures of the day, including Handel, Vivaldi, Gluck, Rameau, and Mozart, and on the fundamental problems of creation, revision, borrowing, influence, and intertextuality. Other essays reinterpret librettos of serious opera in the French and Italian theater during the later eighteenth century. Sister arts, notably painting, the novel, ballet, and the spoken stage are also examined in their relationship to the development of opera. Bracketing the collection are studies of the early pastoral opera and of Prokofief, which expand our historical view of operatic life during the Age of Reason. The book contains numerous rare illustrations, and will be of interest to scholars and students of opera and theater history.
