The Silmarillion

It is not said that Aredhel was wholly unwilling, nor that her life in Nan Elmoth was hateful to her for many years. For though at Eol's command she must shun the sunlight, they wandered far together under the stars or by the light of the sickle moon; or she might fare alone as she would, save that Eol forbade her to seek the sons of Feanor, or any others of the Noldor. And Aredhel bore to Eol a son in the shadows of Nan Elmoth, and in her heart she gave him a name in the forbidden tongue of the Noldor, Lomion, that signifies Child of the Twilight; but his father gave him no name until he was twelve years old. Then he called him Maeglin, which is Sharp Glance, for he perceived that the eyes of his son were more piercing than his own, and his thought could read the secrets of hearts beyond the mist of words.

As Maeglin grew to full stature he resembled in face and form rather his kindred of the Noldor, but in mood and mind he was the son of his father. His words were few save in matters that touched him near, and then his voice had a power to move those that heard him and to overthrow those that withstood him. He was tall and black-haired; his eyes were dark, yet bright and keen as the eyes of the Noldor, and his skin was white. Often he went with Eol to the cities of the Dwarves in the east of Ered Lindon, and there he learned eagerly what they would teach, and above all the craft of finding the ores of metals in the mountains.

Yet it is said that Maeglin loved his mother better, and if Eol were abroad he would sit long beside her and listen to all that she could tell him of her kin and their deeds in Eldamar, and of the might and valour of the princes of the House of Fingolfin. All these things he laid to heart, but most of all that which he heard of Turgon, and that he had no heir; for Elenwe his wife perished in the crossing of the Helcaraxe, and his daughter Idril Celebrindal was his only child.

In the telling of these tales there was awakened in Aredhel a desire to see her own kin again, and she marvelled that she had grown weary of the light of Gondolin, and the fountains in the sun, and the green sward of Tumladen under the windy skies of spring; moreover she was often alone in the shadows when both her son and her husband were away.

Of these tales also grew the first quarrels of Maeglin and Eol. For by no means would his mother reveal to Maeglin where Turgon dwelt, nor by what means one might come thither, and he bided his time, trusting yet to wheedle the secret from her, or perhaps to read her unguarded mind; but ere that could be done he desired to look on the Noldor and speak with the sons of Feanor, his kin, that dwelt not far away. But when he declared his purpose to Eol, his father was wrathful. 'You are of the house of Eol, Maeglin, my son,' he said, 'and not of the Golodhrim. All this land is the land of the Teleri, and I will not deal nor have my son deal with the slayers of our kin, the invaders and usurpers of our homes.

In this you shall obey me, or I will set you in bonds.' And Maeglin did not answer, but was cold and silent, and went abroad no more with Eol; and Eol mistrusted him.

It came to pass that at the midsummer the Dwarves, as was their custom, bade Eol to a feast in Nogrod; and he rode away. Now Maeglin and his mother were free for a while to go where they wished, and they rode often to the eaves of the wood, seeking the sunlight; and desire grew hot in Maeglin's heart to leave Nan Elmoth for ever. Therefore he said to Aredhel: 'Lady, let us depart while there is time? What hope is there in this wood for you or for me? Here we are held in bondage, and no profit shall I find here; for I have learned all that my father has to teach, or that the Naugrim will reveal to me. Shall we not seek for Gondolin? You shall be my guide, and I will be your guard!'

Then Aredhel was glad, and looked with pride upon her son; and telling the servants of Eol that they went to seek the sons of Feanor they departed and rode away to the north eaves of Nan Elmoth. There they crossed the slender stream of Celon into the land of Himlad and rode on to the Fords of Aros, and so westward along the fences of Doriath.

Now Eol returned out of the east sooner than Maeglin had foreseen, and found his wife and his son but two days gone; and so great was his anger that he followed after them even by the light of day. As he entered the Himlad he mastered his wrath and went warily, remembering his danger, for Celegorm and Curufin were mighty lords who loved Eol not at all, and Curufin moreover was of perilous mood; but the scouts of Aglon had marked the riding of Maeglin and Aredhel to the Fords of Aros, and Curufin perceiving that strange deeds were afoot came south from the Pass and encamped near the Fords. And before Eol had ridden far across the Himlad he was waylaid by the riders of Curufin, and taken to their lord.

Then Curufin said to Eol: 'What errand have you, Dark Elf, in my lands? An urgent matter, perhaps, that keeps one so sun-shy abroad by day.'

And Eol knowing his peril restrained the bitter words that arose in his mind. 'I have learned. Lord Curufin,' he said. 'that my son and my wife, the White Lady of Gondolin, have ridden to visit you while I was from home; and it seemed to me fitting that I should join them on this errand.'

Then Curufin laughed at Eol, and he said: 'They might have found their welcome here less warm than they hoped, had you accompanied them; but it is no matter, for that was not their errand. It is not two days since they passed  over the Arossiach, and thence rode swiftly westward. It seems that you would deceive me; unless indeed you yourself have been deceived.'

And Eol answered: 'Then, lord, perhaps you will give me leave to go, and discover the truth of this matter.'

'You have my leave, but not my love,' said Curufin. 'The sooner you depart from my land the better will it please me.'

Then Eol mounted his horse, saying: 'It is good, Lord Curufin, to find a kinsman thus kindly at need. I will remember it when I return.' Then Curufin looked darkly upon Eol. 'Do not flaunt the title of your wife before me,' he said. 'For those who steal the daughters of the Noldor and wed them without gift or leave do not gain kinship with their kin. I have given you leave to go. Take it, and be gone. By the laws of the Eldar I may not slay you at this time. And this counsel I add: return now to your dwelling in the darkness of Nan El-moth; for my heart warns me that if you now pursue those who love you no more, never will you return thither.'

Then Eol rode off in haste, and he was filled with hatred of all the Noldor; for he perceived now that Maeglin and Aredhel were fleeing to Gondolin. And driven by anger and the shame of his humiliation he crossed the Fords of Aros and rode hard upon the way that they had gone before; but though they knew not that he followed them, and he had the swiftest steed, he came never in sight of them until they reached the Brithiach, and abandoned their horses.
