§ Of Beren and Lúthien The Silmarillion

Then Thingol's mood was softened; and Beren sat before his throne upon the left, and Lúthien upon the right, and they told all the tale of the Quest, while all there listened and were filled with amazement. And it seemed to Thingol that this Man was unlike all other mortal Men, and among the great in Arda, and the love of Lúthien a thing new and strange; and he perceived that their doom might not be withstood by any power of the world. Therefore at the last he yielded his will, and Beren took the hand of Lúthien before the throne of her father.
