The scene changes to Olympus, where the Gods are sleeping ("Dormons, dormons"). Cupidon and Vénus enter separately from amatory nocturnal escapades and join their sleeping colleagues, but everyone is soon woken by the sound of the horn of Diane, supposedly chaste huntress and goddess. She laments the sudden absence of Actaeon, her current love ("Quand Diane descend dans la plaine"); to her indignation, Jupiter tells her he has turned Actaeon into a stag to protect her reputation. Mercury arrives and reports that he has visited the Underworld, to which Pluton has just returned with a beautiful woman. Pluton enters, and is taken to task by Jupiter for his scandalous private life. To Pluton's relief the other Gods choose this moment to revolt against Jupiter's reign, their boring diet of ambrosia and nectar, and the sheer tedium of Olympus ("Aux armes, dieux et demi-dieux!"). Jupiter's demands to know what is going on lead them to point out his hypocrisy in detail, poking fun at all his mythological affairs ("Pour séduire Alcmène la fière").
