Elwin Ransom
Elwin Ransom may be based on C. S. Lewis' friend J. R. R. Tolkien ("Elwin" means "Elf friend" in Anglo-Saxon), though he seems to have autobiographical elements. In "That Hideous Strength" Ransom, with his royal charisma and matter-of-fact breezy acceptance of the supernatural, appears less like Tolkien than like Charles Williams (or some of the heroes in Williams' books).
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.
