The Silmarillion

These Yavanna took; and then the Trees died, and their lifeless stems stand yet in Valinor, a memorial of vanished joy. But the flower and the fruit Yavanna gave to Aulë, and Manwë hallowed them, and Aulë and his people made vessels to hold them and preserve their radiance: as is said in the Narsilion, the Song of the Sun and Moon. These vessels the Valar gave to Varda, that they might become lamps of heaven, outshining the ancient stars, being nearer to Arda; and she gave them power to traverse the lower regions of Ilmen, and set them to voyage upon appointed courses above the girdle of the Earth from the West unto the East and to return.

These things the Valar did, recalling in their twilight the darkness of the lands of Arda; and they resolved now to illumine Middle-earth and with light to hinder the deeds of Melkor. For they remembered the Avari that remained by the waters of their awakening, and they did not utterly forsake the Noldor in exile; and Manwë knew also that the hour of the coming of Men was drawn nigh. And it is said indeed that, even as the Valar made war upon Melkor for the sake of the Quendi, so now for that time they forbore for the sake of the Hildor, the Aftercomers, the younger Children of Ilúvatar. For so grievous had been the hurts of Middle-earth in the war upon Utumno that the Valar feared lest even worse should now befall; whereas the Hildor should be mortal, and weaker than the Quendi to withstand fear and tumult. Moreover it was not revealed to Manwë where the beginning of Men should be, north, south, or east. Therefore the Valar sent forth light, but made strong the land of their dwelling.

Isil the Sheen the Vanyar of old named the Moon, flower of Telperion in Valinor; and Anar the Fire-golden, fruit of Laurelin, they named the Sun. But the Noldor named them also Rána, the Wayward, and Vása, the Heart of Fire, that awakens and consumes; for the Sun was set as a sign for the awakening of Men and the waning of the Elves, but the Moon cherishes their memory.

The maiden whom the Valar chose from among the Maiar to guide the vessel of the Sun was named Arien, and he that steered the island of the Moon was Tilion. In the days of the Trees Arien had tended the golden flowers in the gardens of Vána, and watered them with the bright dews of Laurelin; but Tilion was a hunter of the company of Oromë, and he had a silver bow. He was a lover of silver, and when he would rest he forsook the woods of Oromë, and going into Lórien he lay hi dream by the pools of Estë, in Telperion's flickering beams; and he begged to be given the task of tending for ever the last Flower of Silver. Arien the maiden was mightier than he, and she was chosen because she had not feared the heats of Laurelin, and was unhurt by them, being from the beginning a spirit of fire, whom Melkor had not deceived nor drawn to his service. Too bright were the eyes of Arien for even the Eldar to look on, and leaving Valinor she forsook the form and raiment which like the Valar she had worn there, and she was as a naked flame, terrible in the fullness of her splendour.

Isil was first wrought and made ready, and first rose into the realm of the stars, and was the elder of the new lights, as was Telperion of the Trees. Then for a while the world had moonlight, and many things stirred and woke that had waited long in the sleep of Yavanna. The servants of Morgoth were filled with amazement, but the Elves of the Outer Lands looked up in delight; and even as the Moon rose above the darkness in the west, Fingolfin let blow his silver trumpets and began his march into Middle-earth, and the shadows of his host went long and black before them.

Tilion had traversed the heaven seven times, and thus was in the furthest east, when the vessel of Arien was made ready. Then Anar arose in glory, and the first dawn of the Sun was like a great fire upon the towers of the Pelóri: the clouds of Middle-earth were kindled, and there was heard the sound of many waterfalls. Then indeed Morgoth was dismayed, and he descended into the uttermost depths of Angband, and withdrew his servants, sending forth great reek and dark cloud to hide his land from the light of the Day-star.

Now Varda purposed that the two vessels should journey in Ilmen and ever be aloft, but not together; each should pass from Valinor into the east and return, the one issuing from the west as the other turned from the east. Thus the first of the new days were reckoned after the manner of the Trees, from the mingling of the lights when Arien and Tilion passed in then- courses, above the middle of the Earth. But Tilion was wayward and uncertain in speed, and held not to his appointed path; and he sought to come near to Arien, being drawn by her splendour, though the flame of Anar scorched him, and the island of the Moon was darkened.
