§ Of the Voyage of Eärendil and the War of Wrath The Silmarillion

Now Eärendil became fast in friendship with Círdan the Shipwright, who dwelt on the Isle of Balar with those of his people who escaped from the sack of the Havens of Brithombar and Eglarest. With the aid of Círdan Eärendil built Vingilot, the Foam-flower, fairest of the ships of song; golden were its oars and white its timbers, hewn in the birchwoods of Nimbrethil, and its sails were as the argent moon. In the Lay of Eärendil is many a thing sung of his adventures in the deep and in lands untrodden, and in many seas and in many isles; but Elwing was not with him, and she sat in sorrow by the mouths of Sirion.
