One of the most popular versions of Cinderella was written in French by Charles Perrault in 1697, under the name Cendrillon. The popularity of his tale was due to his additions to the story, including the pumpkin, the fairy-godmother and the introduction of glass slippers.
The first moral of the story is that beauty is a treasure, but graciousness is priceless. Without it, nothing is possible; with it, one can do anything.
However, the second moral of the story mitigates the first one and reveals the criticism that Perrault is aiming at: "Another moral: Without doubt it is a great advantage to have intelligence, courage, good breeding, and common sense. These, and similar talents come only from heaven, and it is good to have them. However, even these may fail to bring you success, without the blessing of a godfather or a godmother."
