Zéphire
Zéphire (or Zéphyre) is an opera by Jean-Philippe Rameau in the form of a one-act acte de ballet. Nothing is known about the date of its composition and in all likelihood it was probably not performed in Rameau's lifetime. The name of its librettist is also unknown but may possibly have been Louis de Cahusac.
The first known performance of Zéphire did not take place until modern times when it was performed on 15 June 1967 at the Jubilee Hall in Aldeburgh, Suffolk, England.
