Emma Livry
in La sylphide

The French ballerina Emma Livry is seen here as she appeared in the 1862 production of La sylphide, a romantic ballet in two acts. 

There were two versions of the ballet; the original choreographed by Filippo Taglioni in 1832, and a second version choreographed by August Bournonville in 1836. Bournonville's is the only version known to have survived and is one of the world's oldest surviving ballets.
