Tolkien’s world is like a song, with repeating scenes and themes throughout the ages. Events repeat themselves with new characters, relationships are formed anew (Beren & Luthien, Aragorn & Arwen). The Ainulindalë plays forever. Which makes it all the more enjoyable to think that Maedros casting himself into a fiery chasm holding a Silmaril was repeated millennia later as Gollum, falling into Mt. Doom, holding the One Ring.
