Cinderella was a classic folk tale from Earth. It was the story of a young girl who found true love and happiness after a period of neglect and abuse at the hands of her evil stepmother and stepsisters.
Pavel Chekov believed the story to be of Russian origin. In 2293, he made a reference to this story to Crewman Dax upon informing him that the magnetic boots used to board Kronos One were discovered in his locker, not realizing Dax's feet were not able to fit into standard boots. He stated that, perhaps on his planet, Dax knew of the tale. (Star Trek VI: The Undiscovered Country)
