Undine (1811). Undine is a fairy-tale novella by Friedrich de la Motte Fouqué in which Undine, a water spirit, marries a knight named Huldebrand in order to gain a soul. It is an early German romance, which has been translated into English and other languages. During the nineteenth century the book was very popular and was, according to The Times in 1843, a book which, of all others, if you ask for it at a foreign library, you are sure to find engaged. The story is descended from Melusine, the French folk-tale of a water-sprite who marries a knight on condition that he shall never see her on Saturdays, when she resumes her mermaid shape. It was also inspired by works by the occultist Paracelsus. An unabridged English translation of the story by William Leonard Courtney and illustrated by Arthur Rackham was published in 1909. George MacDonald thought Undine the most beautiful of all fairy stories, while Lafcadio Hearn referred to Undine as a fine German story in his essay The Value of the Supernatural in Fiction. The references to Undine in such works as Charlotte Yonge's The Daisy Chain and Louisa Alcott's Little Women show that it was one of the best loved of all books for many 19th-century children. The first adaptation of Undine was E. T. A. Hoffmann's opera in 1816. It was a collaboration between Hoffmann, who composed the score, and Friedrich de la Motte Fouqué who adapted his own work into a libretto. The opera proved highly successful, and Carl Maria von Weber admired it in his review as the kind of composition which the German desires: an art work complete in itself, in which partial contributions of the related and collaborating arts blend together, disappear, and, in disappearing, somehow form a new world. In the 1830s, the novella was translated into Russian dactylic hexameter verse by the Romantic poet Vasily Zhukovsky. This verse translation became a classic in its own right and later provided the basis for the libretto to Tchaikovsky's operatic adaptation. The novella has since inspired numerous similar adaptions in various genres and traditions.
