"But the jewel burned the hand of Maedhros in pain unbearable; and he perceived that it was as Eonwe had said, and that his right thereto had become void, and that the oath was vain. And being in anguish and despair he cast himself into a gaping chasm filled with fire, and so ended; and the Silmaril that he bore was taken into the bosom of the Earth." (J.R.R. Tolkien "The Silmarillion")
