Iolanta
Princess Iolanta has been blind since birth, but her father King René has kept this from her. Physician Ibn-Hakia says she can be cured only if she learns she is blind and wants to see. Count Vaudémont enters her garden and falls in love with her; when she cannot distinguish a red rose from a white one, he explains light and color. René threatens Vaudémont to motivate Iolanta, who agrees to treatment. It succeeds, and she rejoices in seeing the world. René releases her from her betrothal to Robert and gives her to Vaudémont.
