Two very different satyrs appear in C.S. Lewis’s works, one in his early pre-conversion poem “The Satyr” in Spirits in Bondage and one in his more mature Narnia books (Mr. Tumnus, but Narnia is also home to a whole race of Fauns). Lewis handles the imagery and associations of the satyr or faun quite differently at these points in his writing career, but both represent a split in the psychology of the human male.
