And Tuor came into Nevrast, and looking upon Belegaer the Great Sea he was enamoured of it, and the sound of it and the longing for it were ever in his heart and ear, and an unquiet was on him that took him at last into the depths of the realms of Ulmo. Then he dwelt in Nevrast alone, and the summer of that year passed, and the doom of Nargothrond drew near; but when the autumn came he saw seven great swans flying south, and he knew them for a sign that he had tarried overlong, and he followed their flight along the shores of the sea. Thus he came at length to the deserted halls of Vinyamar beneath Mount Taras, and he entered in, and found there the shield and hauberk, and the sword and helm, that Turgon had left there by the command of Ulmo long before; and he arrayed himself in those arms, and went down to the shore. But there came a great storm out of the west, and out of that storm Ulmo the Lord of Waters arose in majesty and spoke to Tuor as he stood beside the sea. And Ulmo bade him depart from that place and seek out the hidden kingdom of Gondolin; and he gave Tuor a great cloak, to mantle him in shadow from the eyes of his enemies.
But in the morning when the storm was passed, Tuor came upon an Elf standing beside the walls of Vinyamar; and he was Voronwe, son of Aranwe, of Gondolin, who sailed in the last ship that Turgon sent into the West. But when that ship returning at last out of the deep ocean foundered in the great storm within sight of the coasts of Middle-earth, Ulmo took him up, alone of all its mariners, and cast him onto the land near Vinyamar; and learning of the command laid upon Tuor by the Lord of Waters Voronwe was filled with wonder, and did not refuse him his guidance to the hidden door of Gondolin. Therefore they set out together from that place, and as the Fell Winter of that year came down upon them out of the north they went warily eastward under the eaves of the Mountains of Shadow/ At length they came in their journeying to the Pools of Ivrin, and looked with grief on the defilement wrought there by the passage of Glaurung the Dragon; but even as they gazed upon it they saw one going northward in haste, and he was a tall Man, clad in black, and bearing a black sword. But they knew not who he was, nor anything of what had befallen in the south; and he passed them by, and they said no word.
And at the last by the power that Ulmo set upon them they came to the hidden door of Gondolin, and passing down the tunnel they reached the inner gate, and were taken by the guard as prisoners. Then they were led up the mighty ravine of Orfalch Echor, barred by seven gates, and brought before Ecthelion of the Fountain, the warden of the great gate at the end of the climbing road; and there Tuor cast aside his cloak, and from the arms that he bore from Vinyamar it was seen that he was in truth one sent by Ulmo. Then Tuor looked down upon the fair vale of Tumladen, set as a green jewel amid the encircling hills; and he saw far off upon the rocky height of Amon Gwareth Gondolin the great, city of seven names, whose fame and glory is mightiest in song of all dwellings of the Elves in the Hither Lands.
At the bidding of Ecthelion trumpets were blown on the towers of the great gate, and they echoed in the hills; and far off but clear there came a sound of answering trumpets blown upon the white walls of the city, flushed with the rose of dawn upon the plain.
Thus it was that the son of Huor rode across Tumladen, and came to the gate of Gondolin; and passing up the wide stairways of the city he was brought at last to the Tower of the King, and looked upon the images of the Trees of Valinor. Then Tuor stood before Turgon son of Fingolfin, High King of the Noldor, and upon the King's right hand there stood Maeglin his sister-son, but upon his left hand sat Idril Celebrindal his daughter; and all that heard the voice of Tuor marvelled, doubting that this were in truth a Man of mortal race, for his words were the words of the Lord of Waters that came to him in that hour. And he gave warning to Turgon that the Curse of Mandos now hastened to its fulfilment, when all the works of the Noldor should perish; and he bade him depart, and abandon the fair and mighty city that he had built, and go down Sirion to the sea.
Then Turgon pondered long the counsel of Ulmo, and there came into his mind the words that were spoken to him in Vinyamar: 'Love not too well the work of thy hands and the devices of thy heart; and remember that the true hope of the Noldor lieth in the West, and cometh from the Sea.' But Turgon was become proud, and Gondolin as beautiful as a memory of Elven Tirion, and he trusted still in its secret and impregnable strength, though even a Vala should gainsay it; and after the Nirnaeth Arnoediad the people of that city desired never again to mingle in the woes of Elves and Men without, nor to return through dread and danger into the West. Shut behind their pathless and enchanted hills they suffered none to enter, though he fled from Morgoth hate-pursued; and tidings of the lands beyond came to them faint and far, and they heeded them little. The spies of Angband sought for them in vain; and their dwelling was as a rumour, and a secret that none could find. Maeglin spoke ever against Tuor in the councils of the King, and his words seemed the more weighty in that they went with Turgon's heart; and at the last he rejected the bidding of Ulmo and refused his counsel. But in the warning of the Vala he heard again the words that were spoken before the departing Noldor on the coast of Araman long ago; and the fear of treason was wakened in Turgon's heart. Therefore in that time the very entrance to the hidden door in the Encircling Mountains was caused to be blocked up; and thereafter none went ever forth from Gondolin on any errand of peace or war, while that city stood. Tidings were brought by Thorondor Lord of Eagles of the fall of Nargothrond, and after of the slaying of Thingol and of Dior his heir, and of the ruin of Doriath; but Turgon shut his ear to word of the woes without, and vowed to march never at the side of any son of Feanor; and his people he forbade ever to pass the leaguer of the hills.
And Tuor remained in Gondolin, for its bliss and its beauty and the wisdom of its people held mm enthralled; and he became mighty in stature and in mind, and learned deeply of the lore of the exiled Elves. Then the heart of Idril was turned to him, and his to her; and Maeglin's secret hatred grew ever greater, for he desired above all things to possess her, the only heir of the King of Gondolin. But so high did Tuor stand in the favour of the King that when he had dwelt there for seven years Turgon did not refuse him even the hand of his daughter; for though he would not heed the bidding of Ulmo, he perceived that the fate of the Noldor was wound with the one whom Ulmo had sent; and he did not forget the words that Huor spoke to him before the host of Gondolin departed from the Battle of Unnumbered Tears.
Then there was made a great and joyful feast, for Tuor had won the hearts of all that people, save only of Maeglin and his secret following; and thus there came to pass the second union of Elves and Men.
