Middle-earth
Another example is C. S. Lewis's "Space Trilogy," in which Earth is also called Middle-earth. Lewis's novels are situated at the approximate time of World War II, with the last novel, "That Hideous Strength," taking place in post-war England, and they specifically bring in references to Tolkien's legendarium (at that time largely unpublished) and treats these references as primary fact within Lewis's fiction. Merlin, of King Arthur fame, is treated as a successor to the Atlantis magic found within "Numinor" (Lewis's unintentional misspelling of Númenor), and similarities can also be found in the Quenya name for Númenor, which is "Atalantë," and Lewis specifically references the earth as Middle-earth twice, both in Chapter 13, "They Have Pulled Down Deep Heaven on Their Heads". Lewis's borrowings came directly from Tolkien himself: they were close friends and shared each other's literary creations. Lewis encouraged Tolkien to persevere with his Middle-earth writings.A small selection from the many books about Tolkien and his created world:
C. S. Lewis
Many books have been inspired by Lewis, including "A Severe Mercy" by his correspondent and friend Sheldon Vanauken. "The Chronicles of Narnia" has been particularly influential. Modern children's literature has been more or less influenced by Lewis's series, such as Daniel Handler's "A Series of Unfortunate Events", Eoin Colfer's "Artemis Fowl", Philip Pullman's "His Dark Materials", and J. K. Rowling's "Harry Potter" . Pullman is an atheist and so fierce a critic of Lewis's work as to be dubbed "the anti-Lewis". He considers C. S. Lewis a negative influence and has accused Lewis of featuring religious propaganda, misogyny, racism, and emotional sadism in his books. Authors of adult fantasy literature such as Tim Powers have also testified to being influenced by Lewis's work.
