The Silmarillion

She went then to the gardens of Lórien and lay down to sleep; but though she seemed to sleep, her spirit indeed departed from her body, and passed in silence to the halls of Mandos. The maidens of Estë tended the body of Míriel, and it remained unwithered; but she did not return. Then Finwë lived in sorrow; and he went often to the gardens of Lórien, and sitting beneath the silver willows beside the body of his wife he called her by her names. But it was unavailing; and alone in all the Blessed Realm he was deprived of joy. After a while he went to Lórien no more.

An his love he gave thereafter to his son; and Fëanor grew swiftly, as if a secret fire were kindled within him. He was tall, and fair of face, and masterful, his eyes piercingly bright and his hair raven-dark; in the pursuit of all his purposes eager and steadfast. Few ever changed his courses by counsel, none by force. He became of all the Noldor, then or after, the most subtle in mind and the most skilled in hand. In his youth, bettering the work of Rúmil, he devised those letters which bear his name, and which the Eldar used ever after; and he it was who, first of the Noldor, discovered how gems greater and brighter than those of the earth might be made with skill. The first gems that Fëanor made were white and colourless, but being set under starlight they would blaze with blue and silver fires brighter than Helluin; and other crystals he made also, wherein things far away could be seen small but clear, as with the eyes of the eagles of Manwë. Seldom were the hands and mind of Fëanor at rest.

While still in his early youth he wedded Nerdanel, the daughter of a great smith named Mahtan, among those of the Noldor most dear to Aulë; and of Mahtan he learned much of the making of things in metal and in stone. Nerdanel also was firm of will, but more patient than Fëanor, desiring to understand minds rather than to master them, and at first she restrained him when the fire of his heart grew too hot; but his later deeds grieved her, and they became estranged. Seven sons she bore to Fëanor; her mood she bequeathed in part to some of them, but not to all.

Now it came to pass that Finwë took as his second wife Indis the Fair. She was a Vanya, close kin of Ingwë the High King, golden-haired and tall, and in all ways unlike Míriel. Finwë loved her greatly, and was glad again. But the shadow of Míriel did not depart from the house of Finwë, nor from his heart; and of all whom he loved Fëanor had ever the chief share of his thought.

The wedding of his father was not pleasing to Fëanor; and he had no great love for Indis, nor for Fingolfin and Finarfin, her sons. He lived apart from them, exploring the land of Aman, or busying himself with the knowledge and the crafts in which he delighted. In those unhappy things which later came to pass, and in which Fëanor was the leader, many saw the effect of this breach within the house of Finwë, judging that if Finwë had endured his loss and been content with the fathering of his mighty son, the courses of Fëanor would have been otherwise, and great evil might have been prevented; for the sorrow and the strife in the house of Finwë is graven in the memory of the Noldorin Elves. But the children of Indis were great and glorious, and their children also; and if they had not lived the history of the Eldar would have been diminished.

Now even while Fëanor and the craftsmen of the Noldor worked with delight, foreseeing no end to their labours, and while the sons of Indis grew to their full stature, the Noontide of Valinor was drawing to its close. For it came to pass that Melkor, as the Valar had decreed, completed the term of his bondage, dwelling for three ages in the duress of Mandos, alone. At length, as Manwë had promised, he was brought again before the thrones of the Valar. Then he looked upon their glory and their bliss, and envy was in his heart; he looked upon the Children of Ilúvatar that sat at the feet of the Mighty, and hatred filled him; he looked upon the wealth of bright gems, and he lusted for them; but he hid his thoughts, and postponed his vengeance.

Before the gates of Valmar Melkor abased himself at the feet of Manwë and sued for pardon, vowing that if he might be made only the least of the free people of Valinor he would aid the Valar in all their works, and most of all in the healing of the many hurts that he had done to the world. And Nienna aided his prayer; but Mandos was silent
