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 Rana, the Wayward, and Vasa, 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 Vana, and watered them with the bright dews of Laurelin; but Tilion was a hunter of the company of Orome, and he had a silver bow. He was a lover of silver, and when he would rest he forsook the woods of Orome, and going into Lorien he lay hi dream by the pools of Este, 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 m 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 Pelori: 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.
Because of the waywardness of Tilion, therefore, and yet more because of the prayers of Lorien and Este, who said that sleep and rest had been banished from the Earth, and the stars were hidden, Varda changed her counsel, and allowed a time wherein the world should still have shadow and half-light. Anar rested therefore a while in Valinor, lying upon the cool bosom of the Outer Sea; and Evening, the time of the descent and resting of the Sun, was the hour of greatest light and joy in Aman. But soon the Sun was drawn down by the servants of Ulmo, and went then in haste under the Earth, and so came unseen to the east and there mounted the heaven again, lest night be over-long and evil walk under the Moon. But by Anar the waters of the Outer Sea were made hot and glowed with coloured fire, and Valinor had light for a while after the passing of Arien. Yet as she journeyed under the Earth and drew towards the east the glow faded and Valinor was dim, and the Valar mourned then most for the death of Laurelin. At dawn the shadows of the Mountains of Defence lay heavy on the Blessed Realm.
Varda commanded the Moon to journey in like manner, and passing under Earth to arise in the east, but only after the Sun had descended from heaven. But Tilion went with uncertain pace, as yet he goes, and was still drawn towards Arien, as he shall ever be; so that often both may be seen above the Earth together, or at times it will chance that he comes so nigh that his shadow cuts off her brightness and there is a darkness amid the day.
Therefore by the coming and going of Anar the Valar reckoned the days thereafter until the Change of the World.
For Tilion tamed seldom in Valinor, but more often would pass swiftly over the western land, over Avathar, or Araman, or Valinor, and plunge in the chasm beyond the Outer Sea, pursuing his way alone amid the grots and caverns at the roots of Arda. There he would often wander long, and late would return.
Still therefore, after the Long Night, the light of Valinor was greater and fairer than upon Middle-earth; for the Sun rested there, and the lights of heaven drew nearer to Earth in that region. But neither the Sun nor the Moon can recall the light that was of old, that came from the Trees before they were touched by the poison of Ungoliant That light lives now in the Silmarils alone.
But Morgoth hated the new lights, and was for a while confounded by this unlooked-for stroke of the Valar.
Then he assailed Tilion, sending spirits of shadow against him, and there was strife in Ilmen beneath the paths of the stars; but Tilion was victorious. And Arien Morgoth feared with a great fear, but dared not come nigh her, having indeed no longer the power; for as he grew in malice, and sent forth from himself the evil that he conceived in lies and creatures of wickedness, his might passed into them and was dispersed, and he himself became ever more bound to the earth, unwilling to issue from his dark strongholds. With shadows he hid himself and his servants from Arien, the glance of whose eyes they could not long endure; and the lands near his dwelling were shrouded in fumes and great clouds.
But seeing the assault upon Tilion the Valar were in doubt, fearing what the malice and cunning of Morgoth might yet contrive against them. Being unwilling to make war upon him in Middle-earth, they remembered nonetheless the ruin of Almaren; and they resolved that the like should not befall Valinor. Therefore at that time they fortified their land anew, and they raised up the mountain-walls of the Pelori to sheer and dreadful heights, east, north, and south.
Their outer sides were dark and smooth, without foothold or ledge, and they fell in great precipices with faces hard as glass, and rose up to towers with crowns of white ice. A sleepless watch was set upon them, and no pass led through them, save only at the Calacirya: but that pass the Valar did not close, because of the Eldar that were faithful, and in the city of Tirion upon the green hill Finarfin yet ruled the remnant of the Noldor in the deep cleft of the mountains. For all those of elven-race, even the Vanyar and Ingwe their lord, must breathe at times the outer air and the wind that comes over the sea from the lands of their birth; and the Valar would not sunder the Teleri wholly from their kin. But in the Calacirya they set strong towers and many sentinels, and at its issue upon the plains of Valmar a host was encamped, so that neither bird nor beast nor elf nor man, nor any creature beside that dwelt in Middle-earth, could pass that leaguer.
