About a half-hour before sunset, Melusine and Amanthis watch as Vavir sleeps at the foot of the sundial. The others have left to look for the missing Hilda and Florian. Vavir confesses that she fears to die without seeing Hilda again. Hilda reveals herself, and Vavir tells her how much Florian loves her, apologising for having loved him. Hilda tells Vavir that the prince had been sent to the island to save her life with his love. If Hilda disappears, she reasons, he would soon forget her.
