Cinderella
A fairy tale from the collection of Charles Perrault. Cinderella, a young girl, is forced by her stepmother and stepsisters to do heavy housework and relaxes by sitting among the cinders by the fireplace. One evening, when the prince of the kingdom is holding a ball, Cinderellas fairy godmother visits her, magically dresses her for the ball, turns a pumpkin into a magnificent carriage for her, warns her not to stay past midnight, and sends her off. Cinderella captivates the prince at the ball but leaves just as midnight is striking, and in her haste she drops a slipper; as the story is usually told in English, the slipper is made of glass. She returns home with her fine clothes turned back into rags and her carriage a pumpkin again. The prince searches throughout the kingdom for the owner of the slipper. Cinderella is the only one whom it fits, and the prince marries her.
The name Cinderella is sometimes applied to a person or group that undergoes a sudden transformation, such as an athletic team that loses frequently and then starts to win steadily.
