Le Jugement de Midas (The Judgement of Midas) is a French comédie mêlée d'ariettes (a kind of opéra comique), in three acts by André Grétry dedicated to Madame de Montesson. It was first performed, with amateur singers, on 28 March 1778 in the private little theatre set up by Madame de Montesson in the apartments of her secret husband Louis Philippe, Duke of Orléans, at the Palais-Royal in Paris.[1] The libretto is by the Irish playwright Thomas Hales (also known by the French name Thomas d'Hèle) with additional contributions by Louis Anseaume. It was based on the burlesque opera Midas (1760) by Kane O'Hara. The public premiere at the Comédie-Italienne took place on 27 June 1778.[2]
