The scene shifts to a huge party the gods are having, where ambrosia, nectar, and propriety are nowhere to be seen ("Vive le vin! Vive Pluton!"). Eurydice is present, disguised as a bacchante ("J'ai vu le dieu Bacchus"), but Jupiter's plan to sneak her out is interrupted by calls for a dance. Jupiter insists on a minuet, which everybody else finds boring ("La la la. Le menuet n'est vraiment si charmant"). Things liven up as the most famous number in the opera, the "Galop infernal", begins, and all present throw themselves into it with wild abandon ("Ce bal est original").
