Lady Hilda has come to tell her fountain about Vavir's now-incarnate lover, and begs it, if it can, to take human form. Mousta, now with the veil, answers for the fountain, telling her that he can take such form, but fears if he does, she will despise him. He is roughly-hewn, ugly: much like their wretched serving-man. Hilda reassures the "spirit of the fountain" that she has loved him for his generous spirit, not his appearance. The "fountain" presses her for a token. She casts her ring in the pool, pledging to be his bride. Mousta takes the ring and reveals himself. Hilda is stunned with horror and amazement. Mousta confesses a genuine love for her goodness and generosity. She wheedles from him the veil of invisibility. Putting it on, she violently scorns him: she will keep her promise to be his bride, but he will never see her again. Wrapped in the veil, she exits, to Mousta's eloquent despair.
