§ Akallabêth The Silmarillion

Of them was sprung, upon the side of his fathers, Bright Eärendil; and in the Lay of Eärendil it is told how at the last, when the victory of Morgoth was almost complete, he built his ship Vingilot, that Men called Rothinzil, and voyaged upon the unsailed seas, seeking ever for Valinor; for he desired to speak before the Powers on behalf of the Two Kindreds, that the Valar might have pity on them and send them help in their uttermost need. Therefore by Elves and Men he is called Eärendil the Blessed, for he achieved his quest after long labours and many perils, and from Valinor there came the host of the Lords of the West. But Eärendil came never back to the lands that he had loved.
