The Padlock (fairy tale)
The Padlock (Italian: Lo catenaccio) is a literary fairy tale written by the Italian poet Giambattista Basile in the Pentamerone, as the ninth story of the second day. It is considered to be one of two rewritings of the Graeco-Roman myth of "Cupid and Psyche" by Basile, the other being "Lo turzo d'oro".
In spite of its origins as a literary tale, it is related to the international cycle of Animal as Bridegroom or The Search for the Lost Husband, in that a human girl marries a supernatural or enchanted husband, loses him and must search for him. Similar stories have been collected from oral tradition across the Mediterranean, in Italy, Greece and Spain, and nearby countries.
