J.R.R. Tolkien’s close friend and fellow Inklings member who wrote The Chronicles of Narnia was C.S. Lewis.
Tolkien and Lewis met at Oxford and became close friends. They were both members of the Inklings, an informal literary group that met mainly at Oxford’s Eagle and Child pub and in Lewis’s rooms at Magdalen College.
Lewis encouraged Tolkien’s writing, and Tolkien helped Lewis return to Christianity. Their friendship included reading drafts aloud and discussing mythology, literature, language, and religion. Tolkien’s The Lord of the Rings and Lewis’s Narnia books developed independently, despite some shared interests.
The Inklings also included writers such as Charles Williams and Owen Barfield. However, Lewis is the member most directly associated with Tolkien in popular accounts because of their long friendship and major fantasy works.
