Of the Noldor in Beleriand
It has been told how by the guidance of Ulmo Turgon of Nevrast discovered the hidden vale of Tumladen; and that (as was after known) lay east of the upper waters of Sirion, in a ring of mountains tall and sheer, and no living thing came there save the eagles of Thorondor. But there was a deep way under the mountains delved in the darkness of the world by waters that flowed out to join the streams of Sirion; and this way Turgon found, and so came to the green plain amid the mountains, and saw the island-hill that stood there of hard smooth stone; for the vale had been a great lake in ancient days. Then Turgon knew that he had found the place of his desire, and he resolved to build there a fair city, a memorial of Tirion upon Tъna; but he returned to Nevrast, and remained there in peace, though he pondered ever in his thought how he should accomplish his design.
Now after the Dagor Aglareb the unquiet that Ulmo set in his heart returned to him, and he summoned many of the hardiest and most skilled of his people, and led them secretly to the hidden vale, and there they began the building of the city that Turgon had devised; and they set a watch all about it, that none might come upon their work from without, and the power of Ulmo that ran in Sirion protected them. But Turgon dwelt still for the most part in Nevrast, until it came to pass that at last the city was full-wrought, after two and fifty years of secret toil. It is said that Turgon appointed its name to be Ondolindл in the speech of the Elves of Valinor, the Rock of the Music of Water, for there were fountains upon the hill; but in the Sindarin tongue the name was changed, and it became Gondolin, the Hidden Rock. Then Turgon prepared to depart from Nevrast and leave his halls in Vinyamar beside the sea; and there Ulmo came to him once again, and spoke with him. And he said: 'Now thou shalt go at last to Gondolin, Turgon; and I will maintain my power in the Vale of Sirion, and in all the waters therein, so that none shall mark thy going, nor shall any find there the hidden entrance against thy will. Longest of all the realms of the Eldaliл shall Gondolin stand against Melkor. But 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.'
And Ulmo warned Turgon that he also lay under the Doom of Mandos, which Ulmo had no power to remove. 'Thus it may come to pass,' he said, 'that the curse of the Noldor shall find thee too ere the end, and treason awake within thy walls. Then they shall be in peril of fire. But if this peril draweth nigh indeed, then even from Nevrast one shall come to warn thee, and from him beyond ruin and fire hope shall be born for Elves and Men. Leave therefore in this house arms and a sword, that in years to come he may find them, and thus shalt thou know him, and not be deceived.' And Ulmo declared to Turgon of what kind and stature should be the helm and mail and sword that he left behind.
Then Ulmo returned to the sea, and Turgon sent forth all his people, even to a third part of the Noldor of Fingolfin's following, and a yet greater host of the Sindar; and they passed away, company by company, secretly, under the shadows of Ered Wethrin, and they came unseen to Gondolin, and none knew whither they had gone. And last of all Turgon arose, and went with his household silently through the hills, and passed the gates in the mountains, and they were shut behind him.
Through many long years none passed inward thereafter, save Hъrin and Huor only; and the host of Turgon came never forth again until the Year of Lamentation after three hundred and fifty years and more. But behind the circle of the mountains the people of Turgon grew and throve, and they put forth their skill in labour unceasing, so that Gondolin upon Amon Gwareth became fair indeed and fit to compare even with Elven Tirion beyond the sea. High and white were its walls, and smooth its stairs, and tall and strong was the Tower of the King. There shining fountains played, and in the courts of Turgon stood images of the Trees of old, which Turgon himself wrought with elven-craft; and the Tree which he made of gold was named Glingal, and the Tree whose flowers he made of silver was named Belthil. But fairer than all the wonders of Gondolin was Idril, Turgon's daughter, she that was called Celebrindal, the Silver-foot, whose hair was as the gold of Laurelin before the coming of Melkor. Thus Turgon lived long in bliss; but Nevrast was desolate, and remained empty of living folk until the ruin of Beleriand.

Now while the city of Gondolin was building in secret, Finrod Felagund wrought in the deep places of Nargothrond; but Galadriel his sister dwelt, as has been told, in Thingol's realm in Doriath. And at times Melian and Galadriel would speak together of Valinor and the bliss of old; but beyond the dark hour of the death of the Trees Galadriel would not go, but ever fell silent. And on a time Melian said: 'There is some woe that lies upon you and your kin. That I can see in you, but all else is hidden from me; for by no vision or thought can I perceive anything that passed or passes in the West: a shadow lies over all the land of Aman, and reaches far out over the sea. Why will you not tell me more?'
'For that woe is past,' said Galadriel; 'and I would take what joy is here left, untroubled by memory. And maybe there is woe enough yet to come, though still hope may seem bright.'
Then Melian looked in her eyes, and said: 'I believe not that the Noldor came forth as messengers of the Valar, as was said at first: not though they came in the very hour of our need. For they speak never of the Valar, nor have their high lords brought any message to Thingol, whether from Manwл, or Ulmo, or even from Olwл the King's brother, and his own folk that went over the sea. For what cause, Galadriel, were the high people of the Noldor driven forth as exiles from Aman? Or what evil lies on the sons of Fлanor that they are so haughty and so fell? Do I not strike near the truth?'
"Near,' said Galadriel; 'save that we were not driven forth, but came of our own will, and against that of the Valar. And through great peril and in despite of the Valar for this purpose we came: to take vengeance upon Morgoth, and regain what he stole.'
Then Galadriel spoke to Melian of the Silmarils, and of the slaying of King Finwл at Formenos: but still she said no word of the Oath, nor of the Kinslaying, nor of the burning of the ships at Losgar. But Melian said: 'Now much you tell me, and yet more I perceive. A darkness you would cast over the long road from Tirion, but I see evil there, which Thingol should learn for his guidance.'
