And I thought it might be too easy!
But in fact, the original is much easier to recognize, because of the "thou" and "thy".
(In a German Tolkien Forum where I also am a member, we a have thread "Zitateraten" as well. But the quotes are much harder to recognize, because when translated, the typical styles of the different races and characters are hardly recognizable anymore. Besides, there are 2 different translations which often cause confusion!)
