The Silmarillion

Now Beren lay in a swoon within the perilous Gate, and death drew nigh him for there was venom on the fangs of the wolf. Lúthien with her lips drew out the venom, and she put forth her failing power to staunch the hideous wound. But behind her in the depths of Angband the rumour grew of great wrath aroused. The host of Morgoth were awakened.

Thus the quest of the Silmaril was like to have ended in ruin and despair; but in that hour above the wall of the valley three mighty birds appeared, flying northward with wings swifter than the wind. Among all birds and beasts the wandering and need of Beren had been noised, and Huan himself had bidden all things watch, that they might bring him aid. High above the realm of Morgoth Thorondor and his vassals soared, and seeing now the madness of the Wolf and Beren's fall they came swiftly down, even as the powers of Angband were released from the toils of sleep.

Then they lifted up Lúthien and Beren from the earth, and bore them aloft into the clouds. Below them suddenly thunder rolled, lightnings leaped upward, and the mountains quaked. Fire and smoke belched forth from Thangorodrim, and flaming bolts were hurled far abroad, falling ruinous upon the lands; and the Noldor in Hithlum trembled. But Thorondor took his way far above the earth, seeking the high roads of heaven, where the sun daylong shines unveiled and the moon walks amid the cloudless stars. Thus they passed swiftly over Dor-nu-Fauglith, and over Taur-nu-Fuin, and came above the hidden valley of Tumladen. No cloud nor mist lay there, and looking down Lúthien saw far below, as a white light starting from a green jewel, the radiance of Gondolin the fair where Turgon dwelt. But she wept, for she thought that Beren would surely die, he spoke no word, nor opened his eyes, and knew thereafter nothing of his flight. And at the last the eagles set them down upon the borders of Doriath; and they were come to that same dell whence Beren had stolen in despair and left Lúthien asleep.

There the eagles laid her at Beren's side and returned to the peaks of Crissaegrim and their high eyries; but Huan came to her, and together they tended Beren, even as before when she healed him of the wound that Curufin gave to him. But this wound was fell and poisonous. Long Beren lay, and his spirit wandered upon the dark borders of death, knowing every an anguish that pursued him from dream to dream. Then suddenly, when her hope was almost spent, he woke again, and looked up, seeing leaves against the sky; and he heard beneath the leaves singing soft and slow beside him Lúthien Tinúviel. And it was spring again.

Thereafter Beren was named Erchamion, which is the One-handed; and suffering was graven in his face. But at last he was drawn back to life by the love of Lúthien, and he arose, and together they walked in the woods once more. And they did not hasten from that place, for it seemed fair to them. Lúthien indeed was willing to wander in the wild without returning, forgetting house and people and all the glory of the Elf-kingdoms, and for a time Beren was content; but he could not for long forget his oath to return to Menegroth, nor would he withhold Lúthien from Thingol for ever. For he held by the law of Men, deeming it perilous to set at naught the will of the father, save at the last need; and is seemed also to him unfit that one so royal and fair as Lúthien should live always in the woods, as the rude hunters among Men, without home or honour or the fair things which are the delight of the queens of the Eldalië. Therefore after a while he persuaded her, and their footsteps forsook the houseless lands; and he passed into Doriath, leading Lúthien home. So their doom willed it.

Upon Doriath evil days had fallen. Grief and silence had come upon all its people when Lúthien was lost. Long they had sought for her in vain. And it is told that in that time Daeron the minstrel of Thingol strayed from the land, and was seen no more. He it was that made music for the dance and song of Lúthien, before Beren came to Doriath; and he had loved her, and set all his thought of her in his music. He became the greatest of all the minstrels of the Elves east of the Sea, named even before Maglor son of Fëanor. But seeking for Lúthien in despair he wandered upon strange paths, and passing over the mountains he came into the East of Middle-earth, where for many ages he made lament beside dark waters for Lúthien, daughter of Thingol, most beautiful of all living things.
