It was an error. She grew ill in the foul air, surrounded by the misery of the prisoners. That night, as I have already recounted, she told me she had gone to the public baths (a rare thing for her, whose fear of water was so great that she washed herself bit by bit with a sponge dipped in a bowl no deeper than a dish of soup) to free her hair and skin from the odor of the shaft, and that she had heard the bath attendants pointing her out to the other patrons.

CHAPTER TWO - UPON THE CATARACT

THE FOLLOWING MORNING, before she left the bartizan, Dorcas cut her hair until she almost seemed a boy, and thrust a white peony through the circulet that confined it. I labored over documents until afternoon, then borrowed a layman's jelab from the sergeant of my clavigers and went out hoping to encounter her. The brown book I carry says there is nothing stranger than to explore a city wholly different from all those one knows, since to do so is to explore a second and unsuspected self. I have found a thing stranger: to explore such a city only after one has lived in it for some time without learning anything of it.

I did not know where the baths Dorcas had mentioned stood, though I had surmised from talk I had heard in court that they existed. I did not know where the bazaar where she bought her cloth and cosmetics was located, or even if there were more than one. I knew nothing, in short, beyond what I could see from the embrasure, and the brief route from the Vincula to the archon's palace. I had, perhaps, a too-ready confidence in my own ability to find my way about in a city so much smaller than Nessus; even so I took the precaution of making certain from time to time, as I trod the crooked streets that straggled down the cliff between cave-houses excavated from the rock and swallow-houses jutting out from it, that I could still see the familiar shape of the bartizan, with its barricaded gate and black gonfalon.

In Nessus the rich live toward the north where the waters of Gyoll are purer, and the poor to the south where they are foul. Here in Thrax that custom no longer held, both because the Acis flowed so swiftly that the excrement of those upstream (who were, of course, but a thousandth part as numerous as those who lived about the northern reaches of Gyoll) hardly affected its flood, and because water taken from above the cataract was conveyed to the public fountains and the homes of the wealthy by aqueducts, so that no reliance had to be put upon the river save when the largest quantities of water - as for manufacturing or wholesale washing -

were required.

Thus in Thrax the separation was by elevation. The wealthiest lived on the lowest slopes near the river, within easy reach of the shops and public offices, where a brief walk brought them to piers from which they could travel the length of the city in slave-rowed caiques. Those somewhat less well off had their houses higher, the middle class in general had theirs higher still, and so on until the very poorest dwelt just below the fortifications at the cliff tops, often in jacals of mud and reeds that could be reached only by long ladders.

I was to see something of those miserable hovels, but for the present I remained in the commercial quarter near the water. There the narrow streets were so thronged with people that I at first thought a festival was in progress, or perhaps that the war - which had seemed so remote while I remained in Nessus but had become progressively more immediate as Dorcas and I journeyed north -

was now near enough to fill the city with those who fled before it. Nessus is so extensive that it has, as I have heard said, five buildings for each living inhabitant. In Thrax that ratio is surely reversed, and on that day it seemed to me at times that there must have been fifty for each roof. Too, Nessus is a cosmopolitan city, so that although one saw many foreigners there, and occasionally even cacogens come by ship from other worlds, one was always conscious that they were foreigners, far from their homes. Here the streets swarmed with diverse humanity, but they merely reflected the diverse nature of the mountain setting, so that when I saw, for example, a man whose hat was made from a bird's pelt with the wings used for ear flaps, or a man in a shaggy coat of kaberu skin, or a man with a tattooed face, I might see a hundred more such tribesmen around the next corner.

These men were eclectics, the descendants of settlers from the south who had mixed their blood with that of the squat, dark autochthons, adopted certain of their customs, and mingled these with still others acquired from the amphitryons farther north and those, in some instances, of even less-known peoples, traders and parochial races. Many of these eclectics favor knives that are curved - or as they are sometimes called, bent - having two relatively straight sections, with an elbow a little toward the point. This shape is said to make it easier to pierce the heart by stabbing beneath the breastbone; the blades are stiffened with a central rib, are sharpened on both sides, and are kept very sharp; there is no guard, and their hafts are commonly of bone. (I have described these knives in detail because they are as characteristic of the region as anything can be said to be, and because it is from them that Thrax takes another of its names: the City of Crooked Knives. There is also the resemblance of the plan of the city to the blade of such a knife, the curve of the defile corresponding to the curve of the blade, the River Acis to the central rib, Acies Castle to the point, and the Capulus to the line at which the steel vanishes into the haft.)

One of the keepers of the Bear Tower once told me that there is no animal so dangerous or so savage and unmanageable as the hybrid resulting when a fighting dog mounts a she-wolf. We are accustomed to think of the beasts of the forest and mountain as wild, and to think of the men who spring up, as it seems, from their soil as savage. But the truth is that there is a wildness more vicious (as we would know better if we were not so habituated to it) in certain domestic animals, despite their understanding so much human speech and sometimes even speaking a few words; and there is a more profound savagery in men and women whose ancestors have lived in cities and towns since the dawn of humanity. Vodalus, in whose veins flowed the undefiled blood of a thousand exultants -

exarchs, ethnarchs, and starosts - was capable of violence unimaginable to the autochthons that stalked the streets of Thrax, naked beneath their huanaco cloaks.

Like the dog-wolves (which I never saw, because they were too vicious to be useful), these eclectics took all that was most cruel and ungovernable from their mixed parentage; as friends or followers they were sullen, disloyal, and contentious; as enemies, fierce, deceitful, and vindictive. So at least I had heard from my subordinates at the Vincula, for eclectics made up more than half the prisoners there.

I have never encountered men whose language, costume, or customs are foreign without speculating on the nature of the women of their race. There is always a connection, since the two are the growths of a single culture, just as the leaves of a tree, which one sees, and the fruit, which one does not see because it is hidden by the leaves, are the growths of a single organism. But the observer who would venture to predict the appearance and flavor of the fruit from the outline of a few leafy boughs seen (as it were) from a distance, must know a great deal about leaves and fruit if he is not to make himself ridiculous.

Warlike men may be born of languishing women, or they may have sisters nearly as strong as themselves and more resolute. And so I, walking among crowds composed largely of these eclectics and the townsmen (who seemed to me not much different from the citizens of Nessus, save that their clothing and their manners were somewhat rougher) found myself speculating on dark-eyed, darkskinned women, women with glossy black hair as thick as the tails of the skewbald mounts of their brothers, women whose faces I imagined as strong yet delicate, women given to ferocious resistance and swift surrender, women who could be won but not bought - if such women exist in this world.

From their arms I traveled in imagination to the places where they might be found, the lonely huts crouched by mountain springs, the hide yurts standing alone in the high pastures. Soon I was as intoxicated with the thought of the mountains as I had been once, before Master Palaemon had told me the correct location of Thrax, with the idea of the sea. How glorious are they, the immovable idols of Urth, carved with unaccountable tools in a time inconceivably ancient, still lifting above the rim of the world grim heads crowned with mitres, tiaras, and diadems spangled with snow, heads whose eyes are as large as towns, figures whose shoulders are wrapped in forests.

Thus, disguised in the dull jelab of a townsman, I elbowed my way down streets packed with humanity and reeking with the odors of ordure and cookery, with my imagination filled with visions of hanging stone, and crystal streams like carcanets. Thecla must, I think, have been taken at least into the foothills of these heights, no doubt to escape the heat of some particularly torrid summer; for many of the scenes that rose in my mind (as it seemed, of their own accord) were noticeably childlike. I saw rock-loving plants whose virginal flowers I beheld with an immediacy of vision no adult achieves without kneeling; abysses that seemed not only frightening but shocking, as though their existence were an affront to the laws of nature; peaks so high they appeared to be literally without summit, as though the whole world had been falling forever from some unimaginable Heaven, which yet retained its hold on these mountains.

Eventually I reached Acies Castle, having walked almost the entire length of the city. I made my identity known to the postern guards there and was permitted to enter and climb to the top of the donjon, as I had once climbed our Matachin Tower before taking my leave of Master Palaemon.

When I had gone there to make my farewell to the only place I had known, I had stood at one of the loftiest points of the Citadel, which was itself poised atop one of the highest elevations in the whole area of Nessus. The city had been spread before me to the limits of vision, with Gyoll traced across it like the green slime of a slug across a map; even the Wall had been visible on the horizon at some points, and nowhere was I beneath the shadow of a summit much superior to my own.

Here the impression was far different. I bestrode the Acis, which leaped toward me down a succession of rocky steps each twice or three times the height of a tall tree. Beaten to a foaming whiteness that glittered in the sunlight, it disappeared beneath me and reappeared as a ribbon of silver racing through a city as neatly contained in its declivity as one of those toy villages in a box that I (but it was Thecla) recalled receiving on a birthday. Yet I stood, as it were, at the bottom of a bowl. On every side the walls of stone ascended, so that to look at any one of them was to believe, for a moment at least, that gravity had been twisted until it stood at right angles to its proper self by some sorcerer's multiplication with imaginary numbers, and the height I saw was properly the level surface of the world. For a watch or more, I think, I stared up at those walls, and traced the spidery lines of the waterfalls that dashed down them in thunder and clean romance to join the Acis, and watched the clouds trapped among them that seemed to press softly against their unyielding sides like sheep bewildered and dismayed among pens of stone.

Then I grew weary at last of the magnificence of the mountains and my mountain dreams - or rather, not weary, but dizzied by them until my head reeled with vertigo, and I seemed to see those merciless heights even when I closed my eyes, and felt that in my dreams, that night and for many nights, I would fall from their precipices, or cling with bloody fingers to their hopeless walls. Then I turned in earnest to the city and reassured myself with the sight of the bartizan of the Vincula, a very modest little cube now, cemented to a cliff that was hardly more than a ripple among the incalculable waves of stone around it. I plotted the courses of the principal streets, seeking (as in a game, to sober myself from my long gazing on the mountains) to identify those I had walked in reaching the castle, and to observe from this new perspective the buildings and market squares I had seen on the way. By eye I looted the bazaars, finding that there were two, one on either side of the river; and I marked afresh the familiar landmarks I had learned to know from the embrasure of the Vincula - the harena, the pantheon, and the archon's palace. Then, when everything I had seen from the ground had been confirmed from my new vantage point, and I felt I understood the spatial relationship of the place at which I stood to what I had known earlier of the plan of the city, I began to explore the lesser streets, peering along the twisted paths that climbed the upper cliffs and probing narrow alleys that often seemed no more than mere bands of darkness between buildings.

In seeking them out, my gaze came at last to the margins of the river again, and I began to study the landings there, and the storehouses, and even the pyramids of barrels and boxes and bales that waited there to be carried aboard some vessel. Now the water no longer foamed, save when it was obstructed by the piers. Its color was nearly indigo, and like the indigo shadows seen at evening on a snowy day, it seemed to slip silently along, sinuous and freezing; but the motion of the hurrying caiques and laden feluccas showed how much turbulence lay concealed beneath that smooth surface, for the larger craft swung their long bowspirits like fencers, and both yawed crabwise at times while their oars threshed the racing eddies.

When I had exhausted all that lay farther downstream, I leaned from the parapet to observe the closest reach of the river and a wharf that was no more than a hundred strides from the postern gate. Looking down at the stevedores there who toiled to unburden one of the narrow river boats, I saw near them, unmoving, a tiny figure with bright hair. At first I thought her a child because she seemed so small beside the burly, nearly naked laborers; but it was Dorcas, sitting at the very edge of the water with her face in her hands.

CHAPTER THREE - OUTSIDE THE JACAL

WHEN I REACHED Dorcas I could not make her speak. It was not simply that she was angry with me, although I thought so at the time. Silence had come upon her like a disease, not injuring her tongue and lips but disabling her will to use them and perhaps even her desire to, just as certain infections destroy our desire for pleasure and even our comprehension of joy in others. If I did not lift her face to mine, she would look at nothing, staring at the ground beneath her feet without, I think, seeing even that, or covering her face with her hands, as she had been covering it when I found her.
