§ Of Beren and Lúthien The Silmarillion

Then Lúthien stood upon the bridge, and declare her power: and the spell was loosed that bound stone to stone, and the gates were thrown down, and the walls opened, and the pits laid bare; and many thralls and captives came forth in wonder and dismay, shielding their eyes against the pale moon light, for they had lain long in the darkness of Sauron. But Beren came not. Therefore Huan and Lúthien sought him in the isle; and Lúthien found him mourning by Felagund. So deep was his anguish that he lay still, and did not hear her feet. Then thinking him already dead she put her arms about him and fell into a dark forgetfulness. But Beren coming back to the light out of the pits of despair lifted her up, and they looked again upon one another; and the day rising over the dark hills shone upon them.
