If you’re fan, you should, at your earliest convenience, go read this essay over at neil Gaiman’s site, about the influence of C. S. Lewis, J. R. R. Tolkien, and G. K. Chesterton on his literary development. It’s completely brilliant and wonderful.
Also, it includes photographs of all three. If you are like me, and read Sandman when you were younger, and perhaps had not at that time or since actually seen a picture of Chesterton, you will be astonished by how obvious the correlation is between the author and Gaiman’s character “Fiddler’s Green.”
