§ Of the Coming of the Elves and the Captivity of Melkor The Silmarillion

In the beginning the Elder Children of Ilúvatar were stronger and greater than they have since become; but not more fair, for though the beauty of the Quendi in the days of their youth was beyond all other beauty that Ilúvatar has caused to be, it has not perished, but lives in the West, and sorrow and wisdom have enriched it. And Oromë loved the Quendi, and named them in their own tongue Eldar, the people of the stars; but that name was after borne only by those who followed him upon the westward road.
