The Silmarillion - J. R. R. Tolkien [23]
And when Valinor was full-wrought and the mansions of the Valar were established, in the midst of the plain beyond the mountains they built their city, Valmar of many bells. Before its western gate there was a green mound, Ezellohar, that is named also Corollairë; and Yavanna hallowed it, and she sat there long upon the green grass and sang a song of power, in which was set all her thought of things that grow in the earth. But Nienna thought in silence, and watered the mould with tears. In that time the Valar were gathered together to hear the song of Yavanna, and they sat silent upon their thrones of council in the Máhanaxar, the Ring of Doom near to the golden gates of Valmar; and Yavanna Kementári sang before them and they watched.
And as they watched, upon the mound there came forth two slender shoots; and silence was over all the world in that hour, nor was there any other sound save the chanting of Yavanna. Under her song the saplings grew and became fair and tall, and came to flower; and thus there awoke in the world the Two Trees of Valinor. Of all things which Yavanna made they have most renown, and about their fate all the tales of the Elder Days are woven.
The one had leaves of dark green that beneath were as shining silver, and from each of his countless flowers a dew of silver light was ever falling, and the earth beneath was dappled with the shadows of his fluttering leaves. The other bore leaves of a young green like the new-opened beech; their edges were of glittering gold. Flowers swung upon her branches in clusters of yellow flame, formed each to a glowing horn that spilled a golden rain upon the ground; and from the blossom of that tree there came forth warmth and a great light. Telperion the one was called in Valinor, and Silpion, and Ninquelótë, and many other names; but Laurelin the other was, and Malinalda, and Culúrien, and many names in song beside.
In seven hours the glory of each tree waxed to full and waned again to naught; and each awoke once more to life an hour before the other ceased to shine. Thus in Valinor twice every day there came a gentle hour of softer light when both trees were faint and their gold and silver beams were mingled. Telperion was the elder of the trees and came first to full stature and to bloom; and that first hour in which he shone, the white glimmer of a silver dawn, the Valar reckoned not into the tale of hours, but named it the Opening Hour, and counted from it the ages of their reign in Valinor. Therefore at the sixth hour of the First Day, and of all the joyful days thereafter, until the Darkening of Valinor, Telperion ceased his time of flower; and at the twelfth hour Laurelin her blossoming. And each day of the Valar in Aman contained twelve hours, and ended with the second mingling of the lights, in which Laurelin was waning but Telperion was waxing. But the light that was spilled from the trees endured long, ere it was taken up into the airs or sank down into the earth; and the dews of Telperion and the rain that fell from Laurelin Varda hoarded in great vats like shining lakes, that were to all the land of the Valar as wells of water and of light. Thus began the Days of the Bliss of Valinor; and thus began also the Count of Time.
But as the ages drew on to the hour appointed by Ilúvatar for the coming of the Firstborn, Middle-earth lay in a twilight beneath the stars that Varda had wrought in the ages forgotten of her labours in Eä. And in the darkness Melkor dwelt, and still often walked abroad, in many shapes of power and fear, and he wielded cold and fire, from the tops of the mountains to the deep furnaces that are beneath them; and whatsoever was cruel or violent or deadly in those days is laid to his charge.
