The Pharaoh's Daughter
The Sergeyev Collection, housed in the Harvard University Theatre Collection, contains choreographic notations of Petipa's 1898 production of "The Pharaoh's Daughter" for Mathilde Kschessinskaya. The notations document Petipa's choreography for the dances of the principal roles, while the rest of the choreography (i.e. for the "corps de ballet" and much of the action sequences) is only vaguely documented. It was this documentation that helped Pierre Lacotte revive the production in the year 2000.
