I'd like to recommend this article, "
Why there is no Jewish Narnia," for all speculative fiction aficionados out there. A good read, some interesting food for thought.
Although it might seem unlikely that anyone would wonder whether the author of The Lord of the Rings was Jewish, the Nazis took no chances. When the publishing firm of Ruetten & Loening was negotiating with J. R. R. Tolkien over a German translation of The Hobbit in 1938, they demanded that Tolkien provide written assurance that he was an Aryan. Tolkien chastised the publishers for “impertinent and irrelevant inquiries,” and-ever the professor of philology- lectured them on the proper meaning of the term: “As far as I am aware none of my ancestors spoke Hindustani, Persian, Gypsy, or any related dialects.” As to being Jewish, Tolkien regretted that “I appear to have no ancestors of that gifted people.”
