The Silmarillon

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.

In the spring of the year after was born in Gondolin Earendil Halfelven, the son of Tuor and Idril Celebrindal; and that was five hundred years and three since the coming of the Noldor to Middle-earth. Of surpassing beauty was Earendil, for a light was in his face as the light of heaven, and he had the beauty and the wisdom of the Eldar and the strength and hardihood of the Men of old; and the Sea spoke ever in his ear and heart, even as with Tuor his father.

Then the days of Gondolin were yet full of joy and peace; and none knew that the region wherein the Hidden Kingdom lay had been at last revealed to Morgoth by the cries of Hurin, when standing in the wilderness beyond the Encircling Mountains and finding no entrance he called on Turgon in despair. Thereafter the thought of Morgoth was bent unceasing on the mountainous land between Anach and the upper waters of Sirion, whither his servants had never passed; yet still no spy or creature out of Angband could come there because of the vigilance of the eagles, and Morgoth was thwarted in the fulfilment of his designs. But Idril Celebrindal was wise and far-seeing, and her heart misgave her, and foreboding crept upon her spirit as a cloud. Therefore in that time she let prepare a secret way, that should lead down from the city and passing out beneath the surface of the plain issue far beyond the walls, northward of Amon Gwareth; and she contrived it that the work was known but to few, and no whisper of it came to Maeglin's ears.
