They would not let him stay as much as an hour. There is no food here, the robot said, no water, no shelter. This is not a place any longer. You may not stay. You may not stay. You may not stay.

  This is not a place any longer.

  Perhaps he could find her in New Chicago, then. He took to the air again, soaring northward and westward over the vast emptiness. The land below him curved away into the hazy horizon, bare, sterile. What had they done with the vestiges of the world that had gone before? Had they turned their gleaming metal beetles loose to clean everything away? Were there no ruins of genuine antiquity anywhere? No scrap of Rome, no shard of Jerusalem, no stump of Fifth Avenue? It was all so barren down there: an empty stage, waiting for its next set to be built. He flew on a great arc across the jutting hump of Africa and on into what he supposed was southern Europe: the little vehicle did all the work, leaving him to doze or stare as he wished. Now and again he saw another flitterflitter pass by, far away, a dark distant winged teardrop outlined against the hard clarity of the sky. He wished there was some way of making radio contact with them, but he had no idea how to go about it. Not that he had anything he wanted to say; he wanted only to hear a human voice. He was utterly isolated. He might just as well have been the last living man on Earth. He closed his eyes and thought of Gioia.

  “Like this?” Phillips asked. In an ivory-paneled oval room sixty stories above the softly glowing streets of New Chicago he touched a small cool plastic canister to his upper lip and pressed the stud at its base. He heard a foaming sound; and then blue vapor rose to his nostrils.

  “Yes,” Cantilena said. “That’s right.”

  He detected a faint aroma of cinnamon, cloves, and something that might almost have been broiled lobster. Then a spasm of dizziness hit him and visions rushed through his head: Gothic cathedrals, the Pyramids, Central Park under fresh snow, the harsh brick warrens of Mohenjo-daro, and fifty thousand other places all at once, a wild roller-coaster ride through space and time. It seemed to go on for centuries. But finally his head cleared and he looked about, blinking, realizing that the whole thing had taken only a moment. Cantilena still stood at his elbow. The other citizens in the room—fifteen, twenty of them—had scarcely moved. The strange little man with the celadon skin over by the far wall continued to stare at him.

  “Well?” Cantilena asked. “What did you think?”

  “Incredible.”

  “And very authentic. It’s an actual New Chicagoan drug. The exact formula. Would you like another?”

  “Not just yet,” Phillips said uneasily. He swayed and had to struggle for his balance. Sniffing that stuff might not have been such a wise idea, he thought.

  He had been in New Chicago a week, or perhaps it was two, and he was still suffering from the peculiar disorientation that that city always aroused in him. This was the fourth time that he had come here, and it had been the same every time. New Chicago was the only one of the reconstructed cities of this world that in its original incarnation had existed after his own era. To him it was an outpost of the incomprehensible future; to the citizens it was a quaint simulacrum of the archaeological past. That paradox left him aswirl with impossible confusions and tensions.

  What had happened to old Chicago was of course impossible for him to discover. Vanished without a trace, that was clear: no Water Tower, no Marina City, no Hancock Center, no Tribune building, not a fragment, not an atom. But it was hopeless to ask any of the million-plus inhabitants of New Chicago about their city’s predecessor. They were only temporaries; they knew no more than they had to know, and all that they had to know was how to go through the motions of whatever it was that they did by way of creating the illusion that this was a real city. They had no need of knowing ancient history.

  Nor was he likely to find out anything from a citizen, of course. Citizens did not seem to bother much about scholarly matters. Phillips had no reason to think that the world was anything other than an amusement park to them. Somewhere, certainly, there had to be those who specialized in the serious study of the lost civilizations of the past—for how, otherwise, would these uncanny reconstructed cities be brought into being? “The planners,” he had once heard Nissandra or Aramayne say, “are already deep into their Byzantium research.” But who were the planners? He had no idea. For all he knew, they were the robots. Perhaps the robots were the real masters of this whole era, who created the cities not primarily for the sake of amusing the citizens but in their own diligent attempt to comprehend the life of the world that had passed away. A wild speculation, yes; but not without some plausibility, he thought.

  He felt oppressed by the party gaiety all about him. “I need some air,” he said to Cantilena, and headed toward the window. It was the merest crescent, but a breeze came through. He looked out at the strange city below.

  New Chicago had nothing in common with the old one but its name. They had built it, at least, along the western shore of a large inland lake that might even be Lake Michigan, although when he had flown over it had seemed broader and less elongated than the lake he remembered. The city itself was a lacy fantasy of slender pastel-hued buildings rising at odd angles and linked by a webwork of gently undulating aerial bridges. The streets were long parentheses that touched the lake at their northern and southern ends and arched gracefully westward in the middle. Between each of the great boulevards ran a track for public transportation—sleek aquamarine bubble-vehicles gliding on soundless wheels—and flanking each of the tracks were lush strips of park. It was beautiful, astonishingly so, but insubstantial. The whole thing seemed to have been contrived from sunbeams and silk.

  A soft voice beside him said, “Are you becoming ill?”

  Phillips glanced around. The celadon man stood beside him: a compact, precise person, vaguely Oriental in appearance. His skin was of a curious gray-green hue like no skin Phillips had ever seen, and it was extraordinarily smooth in texture, as though he were made of fine porcelain.

  He shook his head. “Just a little queasy,” he said. “This city always scrambles me.”

  “I suppose it can be disconcerting,” the little man replied. His tone was furry and veiled, the inflection strange. There was something feline about him. He seemed sinewy, unyielding, almost menacing. “Visitor, are you?”

  Phillips studied him a moment. “Yes,” he said.

  “So am I, of course.”

  “Are you?”

  “Indeed.” The little man smiled. “What’s your locus? Twentieth century? Twenty-first at the latest, I’d say.”

  “I’m from 1984. 1984 A.D.”

  Another smile, a self-satisfied one. “Not a bad guess, then.” A brisk tilt of the head. “Y’ang-Yeovil.”

  “Pardon me?” Phillips said.

  “Y’ang-Yeovil. It is my name. Formerly Colonel Y’ang-Yeovil of the Third Septentriad.”

  “Is that on some other planet?” asked Phillips, feeling a bit dazed.

  “Oh, no, not at all,” Y’ang-Yeovil said pleasantly. “This very world, I assure you. I am quite of human origin. Citizen of the Republic of Upper Han, native of the city of Port Ssu. And you—forgive me—your name—?”

  “I’m sorry. Phillips. Charles Phillips. From New York City, once upon a time.”

  “Ah, New York!” Y’ang-Yeovil’s face lit with a glimmer of recognition that quickly faded. “New York—New York—it was very famous, that I know—”

  This is very strange, Phillips thought. He felt greater compassion for poor bewildered Francis Willoughby now. This man comes from a time so far beyond my own that he barely knows of New York—he must be a contemporary of the real New Chicago, in fact; I wonder whether he finds this version authentic—and yet to the citizens this Y’ang-Yeovil too is just a primitive, a curio out of antiquity—

  “New York was the largest city of the United States of America,” Phillips said.

  “Of course. Yes. Very famous.”

  “But virtually forgotten by the time the Republic of Upper Ha
n came into existence, I gather.”

  Y’ang-Yeovil said, looking uncomfortable, “There were disturbances between your time and mine. But by no means should you take from my words the impression that your city was—”

  Sudden laughter resounded across the room. Five or six newcomers had arrived at the party. Phillips stared, gasped, gaped. Surely that was Stengard—and Aramayne beside him—and that other woman, half-hidden behind them—

  “If you’ll pardon me a moment—” Phillips said, turning abruptly away from Y’ang-Yeovil. “Please excuse me. Someone just coming in—a person I’ve been trying to find ever since—”

  He hurried toward her.

  “Gioia?” he called. “Gioia, it’s me! Wait! Wait!”

  Stengard was in the way. Aramayne, turning to take a handful of the little vapor-sniffers from Cantilena, blocked him also. Phillips pushed through them as though they were not there. Gioia, halfway out the door, halted and looked toward him like a frightened deer.

  “Don’t go,” he said. He took her hand in his.

  He was startled by her appearance. How long had it been since their strange parting on that night of mysteries in Chang-an? A year? A year and a half? So he believed. Or had he lost all track of time? Were his perceptions of the passing of the months in this world that unreliable? She seemed at least ten or fifteen years older. Maybe she really was; maybe the years had been passing for him here as in a dream, and he had never known it. She looked strained, faded, worn. Out of a thinner and strangely altered face her eyes blazed at him almost defiantly, as though saying, See? See how ugly I have become?

  He said, “I’ve been hunting for you for—I don’t know how long it’s been, Gioia. In Mohenjo, in Timbuctoo, now here. I want to be with you again.”

  “It isn’t possible.”

  “Belilala explained everything to me in Mohenjo. I know that you’re a short-timer—I know what that means, Gioia. But what of it? So you’re beginning to age a little. So what? So you’ll only have three or four hundred years, instead of forever. Don’t you think I know what it means to be a short-timer? I’m just a simple ancient man of the twentieth century, remember? Sixty, seventy, eighty years is all we would get. You and I suffer from the same malady, Gioia. That’s what drew you to me in the first place. I’m certain of that. That’s why we belong with each other now. However much time we have, we can spend the rest of it together, don’t you see?”

  “You’re the one who doesn’t see, Charles,” she said softly.

  “Maybe. Maybe I still don’t understand a damned thing about this place. Except that you and I—that I love you—that I think you love me—”

  “I love you, yes. But you don’t understand. It’s precisely because I love you that you and I—you and I can’t—”

  With a despairing sigh she slid her hand free of his grasp. He reached for her again, but she shook him off and backed up quickly into the corridor.

  “Gioia?”

  “Please,” she said. “No. I would never have come here if I knew you were here. Don’t come after me. Please. Please.”

  She turned and fled.

  He stood looking after her for a long moment. Cantilena and Aramayne appeared, and smiled at him as if nothing at all had happened. Cantilena offered him a vial of some sparkling amber fluid. He refused with a brusque gesture. Where do I go now, he wondered? What do I do? He wandered back into the party.

  Y’ang-Yeovil glided to his side. “You are in great distress,” the little man murmured.

  Phillips glared. “Let me be.”

  “Perhaps I could be of some help.”

  “There’s no help possible,” said Phillips. He swung about and plucked one of the vials from a tray and gulped its contents. It made him feel as if there were two of him, standing on either side of Y’ang-Yeovil. He gulped another. Now there were four of him. “I’m in love with a citizen,” he blurted. It seemed to him that he was speaking in chorus.

  “Love. Ah. And does she love you?”

  “So I thought. So I think. But she’s a short-timer. Do you know what that means? She’s not immortal like the others. She ages. She’s beginning to look old. And so she’s been running away from me. She doesn’t want me to see her changing. She thinks it’ll disgust me, I suppose. I tried to remind her just now that I’m not immortal either, that she and I could grow old together, but she—”

  “Oh, no,” Y’ang-Yeovil said quietly. “Why do you think you will age? Have you grown any older in all the time you have been here?”

  Phillips was nonplussed. “Of course I have. I—I—”

  “Have you?” Y’ang-Yeovil smiled. “Here. Look at yourself.” He did something intricate with his fingers and a shimmering zone of mirror-like light appeared between them. Phillips stared at his reflection. A youthful face stared back at him. It was true, then. He had simply not thought about it. How many years had he spent in this world? The time had simply slipped by: a great deal of time, though he could not calculate how much. They did not seem to keep close count of it here, nor had he. But it must have been many years, he thought. All that endless travel up and down the globe—so many cities had come and gone—Rio, Rome, Asgard, those were the first three that came to mind—and there were others; he could hardly remember every one. Years. His face had not changed at all. Time had worked its harshness on Gioia, yes, but not on him.

  “I don’t understand,” he said. “Why am I not aging?”

  “Because you are not real,” said Y’ang-Yeovil. “Are you unaware of that?”

  Phillips blinked. “Not—real?”

  “Did you think you were lifted bodily out of your own time?” the little man asked. “Ah, no, no, there is no way for them to do such a thing. We are not actual time travelers: not you, not I, not any of the visitors. I thought you were aware of that. But perhaps your era is too early for a proper understanding of these things. We are very cleverly done, my friend. We are ingenious constructs, marvelously stuffed with the thoughts and attitudes and events of our own times. We are their finest achievement, you know: far more complex even than one of these cities. We are a step beyond the temporaries—more than a step, a great deal more. They do only what they are instructed to do, and their range is very narrow. They are nothing but machines, really. Whereas we are autonomous. We move about by our own will; we think, we talk, we even, so it seems, fall in love. But we will not age. How could we age? We are not real. We are mere artificial webworks of mental responses. We are mere illusions, done so well that we deceive even ourselves. You did not know that? Indeed, you did not know?”

  He was airborne, touching destination buttons at random. Somehow he found himself heading back toward Timbuctoo. This city is closed. This is not a place any longer. It did not matter to him. Why should anything matter?

  Fury and a choking sense of despair rose within him. I am software, Phillips thought. I am nothing but software.

  Not real. Very cleverly done. An ingenious construct. A mere illusion.

  No trace of Timbuctoo was visible from the air. He landed anyway. The gray sandy earth was smooth, unturned, as though there had never been anything there. A few robots were still about, handling whatever final chores were required in the shutting-down of a city. Two of them scuttled up to him. Huge bland gleaming silver-skinned insects, not friendly.

  “There is no city here,” they said. “This is not a permissible place.”

  “Permissible by whom?”

  “There is no reason for you to be here.”

  “There’s no reason for me to be anywhere,” Phillips said. The robots stirred, made uneasy humming sounds and ominous clicks, waved their antennae about. They seemed troubled, he thought. They seem to dislike my attitude. Perhaps I run some risk of being taken off to the home for unruly software for debugging. “I’m leaving now,” he told them. “Thank you. Thank you very much.” He backed away from them and climbed into his flitterflitter. He touched more destination buttons.

  We move about by ou
r own will. We think, we talk, we even fall in love.

  He landed in Chang-an. This time there was no reception committee waiting for him at the Gate of Brilliant Virtue. The city seemed larger and more resplendent: new pagodas, new palaces. It felt like winter: a chilly cutting wind was blowing. The sky was cloudless and dazzlingly bright. At the steps of the Silver Terrace he encountered Francis Willoughby, a great hulking figure in magnificent brocaded robes, with two dainty little temporaries, pretty as jade statuettes, engulfed in his arms. “Miracles and wonders! The silly lunatic fellow is here, too!” Willoughby roared. “Look, look, we are come to far Cathay, you and I!”

  We are nowhere, Phillips thought. We are mere illusions, done so well that we deceive even ourselves.

  To Willoughby he said, “You look like an emperor in those robes, Francis.”

  “Aye, like Prester John!” Willoughby cried. “Like Tamburlaine himself! Aye, am I not majestic?” He slapped Phillips gaily on the shoulder, a rough playful poke that spun him halfway about, coughing and wheezing. “We flew in the air, as the eagles do, as the demons do, as the angels do! Soared like angels! Like angels!” He came close, looming over Phillips. “I would have gone to England, but the wench Belilala said there was an enchantment on me that would keep me from England just now; and so we voyaged to Cathay. Tell me this, fellow, will you go witness for me when we see England again? Swear that all that has befallen us did in truth befall? For I fear they will say I am as mad as Marco Polo, when I tell them of flying to Cathay.”

  “One madman backing another?” Phillips asked. “What can I tell you? You still think you’ll reach England, do you?” Rage rose to the surface in him, bubbling hot. “Ah, Francis, Francis, do you know your Shakespeare? Did you go to the plays? We aren’t real. We aren’t real. We are such stuff as dreams are made on, the two of us. That’s all we are. O brave new world! What England? Where? There’s no England. There’s no Francis Willoughby. There’s no Charles Phillips. What we are is—”

  “Let him be, Charles,” a cool voice cut in.
