During the course of his life J. R. R. Tolkien composed a lot of poems. He tried his hand at various styles, applying them successfully to show where the poem belonged, what inspired it or which culture it could be related to. One of the most interesting examples of Tolkien’s verse is The Hoard.
Mysteries are something that in many ways appeals to humans: the unknown is always intriguing. In the world of Arda there are some unresolved mysteries that inspire a lot of questions. Even in such a detailed and thought-out world not everything was explained by Tolkien, so these lacunae often offer a great freedom for speculation. One of the greatest mysteries of Arda is Tom Bombadil.
