Pierre-Louis Moline (1739 – 1820) was a prolific French dramatist, poet and librettist. His play La Réunion du six août was one of the longest-running patriotic pieces during the time of the French Revolution with 52 performances at the Paris Opéra. He is best remembered today for having adapted Calzabigi’s libretto for Gluck’s Orphée et Euridice. Wikipedia
