Correct me if I'm wrong:
Tolkien and C.S. Lewis were good friends. After The Hobbit was written, C.S. Lewis prompted him to write and "adult" version, which is LOTR. Conversely, after C.S. Lewis had written The Space Trilogy Tolkien prompted Lewis to write a novel for children, which produced Lewis' The Chronicles of Narnia.
I've read 'em all and Lewis' Christian paradigm in his trilogy blew my mind. The third novel is spot on for what's currently happening in higher education institutions.
that sounds about right
and I read the Narnia books as a kid (after having had the FOTR books read to me as bed time stories by my mom), and never saw the whole Christianity thing iin them. I was in my 20's when someone brought that up, and I re-read them again, and thought 'hmm...I guess I can see that...", but it still didn't jump out at me
