When I had first come to realize, as a boy, that the green circle of the moon was in fact a sort of island hung in the sky, whose color derived from forests, now immemorially old, planted in the earliest days of the race of Man, I had formed an intention of going there, and had added to it all the other worlds of the universe as I came in time to realize their existence. I had abandoned that wish as a part (I thought) of growing up, when I learned that only people whose positions in society appeared to me unattainably high ever succeeded in leaving Urth.

Now that old longing was rekindled again, and though it seemed to have grown more absurd still with the passage of the years (for surely the little apprentice I had been had more chance of flashing between the stars at last than the hunted outcast I had become) it was immensely firmer and stronger because I had learned in the intervening time the folly of limiting desire to the possible. I would go, I was resolved. For the remainder of my life I would be sleeplessly alert for any opportunity, however slight. Already I had found myself once alone with the mirrors of Father Inire; then Jonas, wiser by far than I, had without hesitation cast himself on the tide of photons. Who could say that I would never find myself before those mirrors again?

With that thought, I snatched my cloak away from my head, resolved to look upon the stars once more, and found that the sunlight had come lancing over the crowns of the mountains to dim them almost to insignificance. The titan faces that loomed above me now were only those of the long-dead rulers of Urth, haggard by time, their cheeks fallen away in avalanches.

I stood and stretched. It was clear that I could not spend the day without food, as I had spent the day before; and clearer still that I could not spend the next night as I had spent this, with no shelter but my cloak. Thus, though I did not dare yet go down into the peopled valleys, I shaped my path to take me to the high forest I could see marching over the slopes below me.

It took most of the morning to reach it When at last I scrambled down to stand among the scrub birches that were its outriders, I saw that although it was more steeply pitched than I had supposed, it contained, toward its center where the ground was somewhat more level and the sparse soil thus a trifle richer, trees of very considerable height, so closely spaced that the apertures between their trunks were hardly wider than the trunks themselves. They were not, of course, the glossy-leaved hardwoods of the tropical forest we had left behind on the south bank of the Cephissus. These were shaggy-barked conifers for the most part, tall, straight trees that leaned, even in their height and strength, away from the shadow of the mountain, and showed plainly in at least a quarter of their number the wounds of their wars with wind and lightning.

I had come hoping to find woodcutters or hunters from whom I might claim the hospitality that everyone (as city people fondly believe) offers to strangers in the wilds. For a long time, however, I was disappointed in that hope. Again and again I paused to listen for the ringing of an ax or the baying of hounds. There was only silence, and indeed, though the trees would have provided a great quantity of lumber, I saw no signs that any had ever been cut.

At last I came across a little brook of ice-cold water that wandered among the trees, fringed with dwarfed and tender bracken and grass as fine as hair. I drank my fill, and for perhaps half a watch followed the water down the slope through a succession of miniature falls and tarns, wondering, as no doubt others have for countless chiliads, to observe it grown slowly larger, though it had recruited no others of its kind that I could see.

Eventually it was swollen until the trees themselves were no longer safe from it, and I saw ahead the trunk of one, four cubits thick at least, that had fallen across it, its roots undermined. I approached it with no great care, for there was no sound to warn me, and bracing myself on a projecting stub vaulted to the top.

Almost I tumbled into an ocean of air. The battlement of Acies Castle, from which I had seen Dorcas in her dejection, was a balustrade compared to that height. Surely the Wall of Nessus is the only work of hands that could rival it. The brook fell silently upon a gulf that blew it to spray, so that it vanished into a rainbow. The trees below might have been toys made for a boy by an indulgent father, and at the edge of them, with a little field beyond, I saw a house no bigger than a pebble, with a wisp of white smoke, the ghost of the ribbon of water that had fallen and died, curling up to disappear like it into nothingness.

To descend the cliff appeared at first only too easy, for the momentum of my vault had nearly carried me over the fallen trunk, which itself hung half over the edge. When I had regained my balance, however, it seemed close to impossible. The rock face was sheer over large areas, so far as I could see, and though perhaps if I had carried a rope I could have let myself down and so reached the house well before night, I of course had none, and in any case would have been very slow to trust a rope of such immense length as would have been required.

I spent some time exploring the top of the cliff, however, and eventually discovered a path that, though very precipitous and very narrow, showed unmistakable signs of use. I will not recount the details of the climb down, which really have little to do with my story, although they were as may be imagined deeply absorbing at the time. I soon learned to watch only the path and the face of the cliff, to my right or left as the path wound back and forth. For most of its length it was a steep descent about a cubit wide or a little less. Occasionally it became a series of descending steps cut into the living rock, and at one point there were only hand and foot holes, which I descended like a ladder. These were far easier-viewed objectively - than the crevices to which I had clung by night at the mouth of the mine of the man-apes, and at least I was spared the shock of crossbow quarrels exploding about my ears; but the height was a hundred times greater, and dizzying.

Perhaps because I was forced to labor so hard to ignore the drop on the opposite side, I became acutely conscious of the vast, sectioned sample of the world's crust down which I crawled. In ancient times - so I read once in one of the texts Master Palaemon set me - the heart of Urth herself was alive, and the shifting motions of that living core made plains erupt like fountains, and sometimes opened seas in a night between islands that had been one continent when last seen by the sun. Now it is said she is dead, and cooling and shrinking within her stony mantle like the corpse of an old woman in one of those abandoned houses Dorcas had described, mummifying in the still, dry air until her clothing falls in upon itself. So it is, it is said, with Urth; and here half a mountain had dropped away from its mating half, falling a league at least.

Chapter 14

The Widow's House

IN SALTUS, WHERE Jonas and I stayed for a few days and where I performed the second and third public decollations of my career, the miners rape the soil of metals, building stones, and even artifacts laid down by civilizations forgotten for chiliads before the Wall of Nessus ever rose. This they do by narrow shafts bored into the hillsides until they strike some rich layer of ruins, or even (if the tunnelers are particularly fortunate) a building that has preserved some part of its structure so that it serves them as a gallery already made.

What was done with so much labor there might have been accomplished on the cliff I descended with almost none. The past stood at my shoulder, naked and defenseless as all dead things, as though it were time itself that had been laid open by the fall of the mountain. Fossil bones protruded from the surface in places, the bones of mighty animals and of men. The forest had set its own dead there as well, stumps and limbs that time had turned to stone, so that I wondered as I descended, if it might not be that Urth is not, as we assume, older than her daughters the trees, and imagined them growing in the emptiness before the face of the sun, tree clinging to tree with tangled roots and interlacing twigs until at last their accumulation became our Urth, and they only the nap of her garment.

Deeper than these lay the buildings and mechanisms of humanity. (And it may be that those of other races lay there as well, for several of the stories in the brown book I carried seemed to imply that colonies once existed here of those beings whom we call the cacogens, though they are in fact of myriad races, each as distinct as our own.) I saw metals there that were green and blue in the same sense that copper is said to be red or silver white, colored metals so curiously wrought that I could not be certain whether their shapes had been intended as works of art or as parts for strange machines, and it may be indeed that among some of those unfathomable peoples there is no distinction.

At one point, only slightly less than halfway down, the line of the fault had coincided with the tiled wall of some great building, so that the windy path I trod slashed across it. What the design was those tiles traced, I never knew; as I descended the cliff I was too near to see it, and when I reached the base at last it was too high for me to discern, lost in the shifting mists of the falling river. Yet as I walked, I saw it as an insect may be said to see the face in a portrait over whose surface it creeps. The tiles were of many shapes, though they fit together so closely, and at first I thought them representations of birds, lizards, fish and suchlike creatures, all interlocked in the grip of life. Now I feel that this was not so, that they were instead the shapes of a geometry I failed to comprehend, diagrams so complex that the living forms seemed to appear in them as the forms of actual animals appear from the intricate geometries of complex molecules.

However that might be, these forms seemed to have little connection with the picture or design. Lines of color crossed them, and though they must have been fired into the substance of the tiles in eons past, they were so willful and bright that they might have been laid on only a moment before by some titanic artist's brush. The shades most used were beryl and white, but though I stopped several times and strove to understand what might be depicted there (whether it was writing, or a face, or perhaps a mere decorative design of lines and angles, or a pattern of intertwined verdure) I could not; and perhaps it was each of those, or none, depending on the position from which it was seen and the predisposition the viewer brought to it. Once this enigmatic wall was passed, the way down grew easier. It was never necessary again for me to climb down a sheer drop, and though there were several more flights of steps, they were not so steep or so narrow as before. I reached the bottom before I expected it, and looked up at the path down which I had traveled with as much wonder as if I had never set foot on it - indeed, I could see several points at which it appeared to have been broken by the spalling away of sections of the cliff, so that it seemed impassable.

The house I had beheld so clearly from above was invisible now, hidden among trees; but the smoke of its chimney still showed against the sky. I made my way through a forest less precipitous than the one through which I had followed the brook. The dark trees seemed, if anything, older. The great ferns of the south were absent there, and in fact I never saw them north of the House Absolute, except for those under cultivation in the gardens of Abdiesus; but there were wild violets with glossy leaves and flowers the exact color of poor Thecla's eyes growing between the roots of the trees, and moss like the thickest green velvet, so that the ground seemed carpeted, and the trees themselves all draped in costly fabric.

Some time before I could see the house or any other sign of human presence, I heard the barking of a dog. At the sound, the silence and wonder of the trees fell back, present still but infinitely more distant. I felt that some mysterious life, old and strange, yet kindly too, had come to the very moment of revealing itself to me, then drawn away like some immensely eminent person, a master of the musicians, perhaps, whom I had struggled for years to attract to my door but who in the act of knocking had heard the voice of another guest who was unpleasing to him and had put down his hand and turned away, never to come again.

Yet how comforting it was. For almost two long days I had been utterly alone, first upon the broken fields of stone, then among the icy beauty of the stars, and then in the hushed breath of the ancient trees. Now that harsh, familiar sound made me think once more of human comfort - not only think of it, but imagine it so vividly that I seemed to feel it already. I knew that when I saw the dog himself he would be like Triskele; and so he was, with four legs instead of three, somewhat longer and narrower in the skull, and more brown than lion-colored, but with the same dancing eyes and wagging tail and lolling tongue. He began with a declaration of war, which he rescinded as soon as I spoke to him, and before I had gone twenty strides he was presenting his ears to be scratched. I came into the little clearing where the house stood with the dog romping about me.

The walls were of stone, hardly higher than my head. The thatched roof was as steep as I have ever seen, and dotted with flat stones to hold down the thatch in high winds. It was, in short, the home of one of those pioneering peasants who are the glory and despair of our Commonwealth, who in one year produce a surplus of food to support the population of Nessus, but who must themselves be fed in the next lest they starve.

When there is no paved path before a door, one can judge how often feet go out and in by the degree to which the grass encroaches on the trodden ground. Here there was only a little circle of dust the size of a kerchief before the stone step. When I saw it, I supposed that I might frighten the person who lived in that cabin (for I supposed there could only be one) if I were to appear at the door unannounced, and so since the dog had long ago ceased to bark, I paused at the edge of the clearing and shouted a greeting.

The trees and the sky swallowed it, and left only silence.

I shouted again and advanced toward the door with the dog at my heels, and had almost reached it when a woman appeared there. She had a delicate face that might easily have been beautiful had it not been for her haunted eyes, but she wore a ragged dress that differed from a beggar's only by being clean. After a moment, a round-faced little boy, larger-eyed even than his mother, peeped past her skirt.

I said, "I am sorry if I startled you, but I have been lost in these mountains."
