The Ballet of the Nuns
Ballet of the 18th century was based on rational thought and classical art. The French Revolution however ushered in a period that brought romantic ballet to the stage. Trapdoors, gas lighting, and other elements that became associated with the romantic ballet had been used in the popular theaters on the Paris boulevards for some time. Such elements would gain official sanction and prestige at the Paris Opéra in the middle decades of the 19th century.
