The prologue sets the stage for the action: Thespis, Momus and Thalie announce the subject of the play. It is a comedy mocking the folly of man...and the story of a trap set by Jupiter to cure Juno of her jealousy. The trap? It consists in convincing the water nymph Platée that Jupiter is in love with her. Mercury officially declares Jupiter’s love to Platée. When the god appears before her – first as a donkey, then an owl - the nymph calls on the birds of the marshes, but they scare Jupiter away. Luckily he quickly returns and declares his love for Platée. He even wants to marry her. La Folie comes to sing for the fiancée during an absolutely chaotic scene. However, as the couple prepares for the wedding, Juno arrives. Furious, she puts an end to the farce and ascends to the heavens with Jupiter. Humiliated, Platée understands she has been duped. She swims off into the marshes, as the chorus sings an ironic song in her honour.
