[2] The ballet performed in act 2 of the opera was Médée et Jason, originally staged four months earlier by Jean-Georges Noverre for Stuttgart and restaged in an abridged form by Gaetano Vestris.
The part of Medea was danced by Marie Allard, that of Creusa, by Marie-Madeleine Guimard, and that of Jason, by Vestris.
[3] The ballet is described in Louis Petit de Bachaumont's Mémoires secrets: This pantomime, which lasts nearly 20 minutes and constitutes an entire play [un poême entière], received the warmest applause.
The passions are painted on his face with a nobility, a truth, a diversity that is inexpressible, and which shows he has a singular talent for the stage.
This choreography [chorégraphie] was devised [imaginée dans le principe] by Noverre, the man who has greatest genius in this genre.
