These fantastic stories have travelled across cultural borders, and been passed on from generation to generation, ever-changing, renewed with each re-telling. Few forms of literature have greater power to enchant us and rekindle our imagination than a fairy tale. But what is a fairy tale? Where do they come from and what do they mean? What do they try and communicate to us about morality, sexuality, and society? The range of fairy tales stretches across great distances and time; their history is entangled with folklore and myth, and their inspiration draws on ideas about nature and the supernatural, imagination and fantasy, psychoanalysis, and feminism. In this Very Short Introduction, Marina Warner digs into a rich hoard of fairy tales in all their brilliant and fantastical variations, in order to define a genre and evaluate a literary form that keeps shifting through time and history. Drawing on a glittering array of examples, from classics such as Red Riding Hood, Cinderella, and The Sleeping Beauty, the Grimm Brothers' Hansel and Gretel, and Hans Andersen's The Little Mermaid, to modern-day realizations including Walt Disney's Snow White, Warner forms a persuasive case for fairy tale as a crucial repository of human understanding and culture.
