 The ultimate source of the story is a myth related by the Greek writer Pausanias in his "Guide to Greece".Rameau's first attempt at comic opera, the plot concerns an ugly water nymph who believes that Jupiter, the king of the gods, is in love with her.The work was initially called a "ballet bouffon", though it was later styled a "comédie lyrique", putting it in the same category as Rameau's "Les Paladins".
