As the Fairytale evolved, emphasis began to be given to it as Story. Madame d'Aulnoy and Charles Perrault were the first to write deliberate fairytales, intended as much for adults as for children. These stories were the first LFs and one of the geneses for written Fantasy outside the oral tradition.
LFs almost always draw on the Motifs, Plot Devices and images of Folktales in order to contextualize their story. Nearly all Revisionist Fantasies are LFs. In that continuum of the Wonder Tale which runs from the oral to the literary tradition, the LF is the highest form of development. Many Fables, too, are LFs. [MA]
