in East of the Sun and West of the Moon, or because the lover has been enchanted into forgetting the hero or heroine, as in The Master Maid, or merely from the belief that the true hero or heroine is dead or lost, as in Maid Maleen. In many such tales with "true brides" and "false brides", such as East of the Sun and West of the Moon, the true bride must bribe her way to the hero for three nights, where the false bride is holding him captive; the first two nights, the false bride drugs the hero, but her pleas are heard by someone else, who warns him. The false bride fails the test when the heroine, not plagued with greed, refuses to trade the bride for gold or treasure; the false bride's greed draws her to agree, and so loses the bridegroom. Another test is to determine which bride can carry out a domestic task to perfection; this, also, is found in East of the Sun and West of the Moon, where the heroine can wash the shirt that neither the false bride nor her mother can. The false bride is sometimes a usurping servant, as in The Goose Girl, The Sleeping Prince or The Love for Three Oranges, but overwhelmingly the substituted bride is the sister or stepsister of the true bride. The substitution is an integral part of Aarne-Thompson type 403A, The Black and the White Bride, including such fairy tales as The White and the Black Bride and Bushy Bride; this often opens with an episode of The Kind and the Unkind Girls (Aarne-Thompson type 480) where the girls' character is revealed. Other tales including this are Brother and Sister and The Wonderful Birch. Hans Christian Andersen's literary tale "The Little Mermaid" makes a variation not usually found in more traditional fairytales. The Temple Girl fits the above prototype, since she gets the credit (which actually belongs to the Mermaid) for saving the Prince's life and wins his love. But unlike in the above-mentioned examples, nobody knows of the Mermaid's role in the rescue (not even the Temple Girl herself, who genuinely thinks that she saved him), and there is no last-moment reprieve: she does get to marry the Prince, and additionally, as the Princess of a neighboring kingdom, she had been chosen as the Prince's bride by their parents. The Mermaid is given
