"Cinderella", or "The Little Glass Slipper", is a folk tale with 69 variants that are told throughout the world. The protagonist is a young girl living in forsaken circumstances who is suddenly blessed by remarkable fortune, with her ascension to the throne via marriage. The story of Rhodopis, recounted by the Greek geographer Strabo sometime between 7 BC and AD 23, about a Greek slave girl who marries the king of Egypt, is usually considered to be the earliest known variant of the Cinderella story.
