Away south upon the Hornburg, in the middle night men heard a great noise, as a wind in the valley, and the ground trembled; and all were afraid and no one ventured to go forth. But in the morning they went out and were amazed; for the slain Orcs were gone, and the trees also. Far down into the valley of the Deep the grass was crushed and trampled brown, as if giant herdsmen had pastured great droves of cattle there; but a mile below the Dike a huge pit had been delved in the earth, and over it stones were piled into a hill. Men believed that the Orcs whom they had slain were buried there; but whether those who had fled into the wood were with them, none could say, for no man ever set foot upon that hill. The Death Down it was afterwards called, and no grass would grow there. But the strange trees were never seen in Deeping-coomb again; they had returned at night, and had gone far away to the dark dales of Fangorn. Thus they were revenged upon the Orcs.
The king and his company slept no more that night; but they saw and heard no other strange thing, save one: the voice of the river beside them suddenly awoke. There was a rush of water hurrying down among the stones; and when it had passed, the Isen flowed and bubbled in its bed again, as it had ever done.
At dawn they made ready to go on. The light came grey and pale, and they did not see the rising of the sun. The air above was heavy with fog, and a reek lay on the land about them. They went slowly, riding now upon the highway. It was broad and hard, and well-tended. Dimly through the mists they could descry the long arm of the mountains rising on their left. They had passed into Nan Curunír, the Wizard’s Vale. That was a sheltered valley, open only to the South. Once it had been fair and green, and through it the Isen flowed, already deep and strong before it found the plains; for it was fed by many springs and lesser streams among the rain-washed hills, and all about it there had lain a pleasant, fertile land.
It was not so now. Beneath the walls of Isengard there still were acres tilled by the slaves of Saruman; but most of the valley had become a wilderness of weeds and thorns. Brambles trailed upon the ground, or clambering over bush and bank, made shaggy caves where small beasts housed. No trees grew there; but among the rank grasses could still be seen the burned and axe-hewn stumps of ancient groves. It was a sad country, silent now but for the stony noise of quick waters. Smokes and steams drifted in sullen clouds and lurked in the hollows. The riders did not speak. Many doubted in their hearts, wondering to what dismal end their journey led.
After they had ridden for some miles, the highway became a wide street, paved with great flat stones, squared and laid with skill; no blade of grass was seen in any joint. Deep gutters, filled with trickling water, ran down on either side. Suddenly a tall pillar loomed up before them. It was black; and set upon it was a great stone, carved and painted in the likeness of a long White Hand. Its finger pointed north. Not far now they knew that the gates of Isengard must stand, and their hearts were heavy; but their eyes could not pierce the mists ahead.
Beneath the mountain’s arm within the Wizard’s Vale through years uncounted had stood that ancient place that Men called Isengard. Partly it was shaped in the making of the mountains, but mighty works the Men of Westernesse had wrought there of old; and Saruman had dwelt there long and had not been idle.
This was its fashion, while Saruman was at his height, accounted by many the chief of Wizards. A great ring-wall of stone, like towering cliffs, stood out from the shelter of the mountain-side, from which it ran and then returned again. One entrance only was there made in it, a great arch delved in the southern wall. Here through the black rock a long tunnel had been hewn, closed at either end with mighty doors of iron. They were so wrought and poised upon their huge hinges, posts of steel driven into the living stone, that when unbarred they could be moved with a light thrust of the arms, noiselessly. One who passed in and came at length out of the echoing tunnel, beheld a plain, a great circle, somewhat hollowed like a vast shallow bowl: a mile it measured from rim to rim. Once it had been green and filled with avenues, and groves of fruitful trees, watered by streams that flowed from the mountains to a lake. But no green thing grew there in the latter days of Saruman. The roads were paved with stone-flags, dark and hard; and beside their borders instead of trees there marched long lines of pillars, some of marble, some of copper and of iron, joined by heavy chains.
Many houses there were, chambers, halls, and passages, cut and tunnelled back into the walls upon their inner side, so that all the open circle was overlooked by countless windows and dark doors. Thousands could dwell there, workers, servants, slaves, and warriors with great store of arms; wolves were fed and stabled in deep dens beneath. The plain, too, was bored and delved. Shafts were driven deep into the ground; their upper ends were covered by low mounds and domes of stone, so that in the moonlight the Ring of Isengard looked like a graveyard of unquiet dead. For the ground trembled. The shafts ran down by many slopes and spiral stairs to caverns far under; there Saruman had treasuries, store-houses, armouries, smithies, and great furnaces. Iron wheels revolved there endlessly, and hammers thudded. At night plumes of vapour steamed from the vents, lit from beneath with red light, or blue, or venomous green.
To the centre all the roads ran between their chains. There stood a tower of marvellous shape. It was fashioned by the builders of old, who smoothed the Ring of Isengard, and yet it seemed a thing not made by the craft of Men, but riven from the bones of the earth in the ancient torment of the hills. A peak and isle of rock it was, black and gleaming hard: four mighty piers of many-sided stone were welded into one, but near the summit they opened into gaping horns, their pinnacles sharp as the points of spears, keen-edged as knives. Between them was a narrow space, and there upon a floor of polished stone, written with strange signs, a man might stand five hundred feet above the plain. This was Orthanc, the citadel of Saruman, the name of which had (by design or chance) a twofold meaning; for in the Elvish speech orthanc signifies Mount Fang, but in the language of the Mark of old the Cunning Mind.
A strong place and wonderful was Isengard, and long it had been beautiful; and there great lords had dwelt, the wardens of Gondor upon the West, and wise men that watched the stars. But Saruman had slowly shaped it to his shifting purposes, and made it better, as he thought, being deceived – for all those arts and subtle devices, for which he forsook his former wisdom, and which fondly he imagined were his own, came but from Mordor; so that what he made was naught, only a little copy, a child’s model or a slave’s flattery, of that vast fortress, armoury, prison, furnace of great power, Barad-dûr, the Dark Tower, which suffered no rival, and laughed at flattery, biding its time, secure in its pride and its immeasurable strength.
