Cinderella, or The Little Glass Slipper, is a folk tale with thousands of variants that are told throughout the world. The protagonist is a young girl living in unfortunate circumstances who is suddenly blessed with remarkable fortune, ultimately ascending to the throne through marriage. The earliest known version of the Cinderella story is usually considered to be the Greek story of Rhodopis, as described by the scholar Strabo sometime between 7 BC and 23 AD, about a Greek slave girl who marries the king of Egypt.
