The City and the Stars/The Sands of Mars

by Arthur C. Clarke

  It did not seem that the ruins could teach them anything, but they searched carefully among the piles of rubble and the great mounds of stone. Here, perhaps, lay the graves of buried machines— the machines that had done their work so long ago. They would be useless now, thought Alvin, if the Invaders returned. Why had they never come back? But that was yet another mystery: he had enough enigmas to deal with— there was no need to seek for any more.

  A few yards from the lake they found a small clearing among the rubble. It had been covered with weeds, but they were now blackened and charred by tremendous heat, so that they crumbled to ashes as Alvin and Hilvar approached, smearing their legs with streaks of charcoal. At the center of the clearing stood a metal tripod, firmly anchored to the ground, and supporting a circular ring which was tilted on its axis so that it pointed to a spot halfway up the sky. At first sight it seemed that the ring enclosed nothing; then, as Alvin looked more carefully, he saw that it was filled with a faint haze that tormented the eye by lurking at the edge of the visible spectrum. It was the glow of power, and from this mechanism, he did not doubt, had come the explosion of light that had lured them to Shalmirane.

  They did not venture any closer, but stood looking at the machine from a safe distance. They were on the right track, thought Alvin; now it only remained to discover who, or what, had set this apparatus here, and what their purpose might be. That tilted ring— it was clearly aimed out into space. Had the flash they had observed been some kind of signal? That was a thought which had breath-taking implications.

  “Alvin,” said Hilvar suddenly, his voice quiet but urgent, “we have visitors.”

  Alvin spun on his heels and found himself staring at a triangle of lidless eyes. That, at least, was his first impression, then behind the staring eyes he saw the outlines of a small but complex machine. It was hanging in the air a few feet above the ground, and it was like no robot he had ever before seen.

  Once the initial surprise had worn off, he felt himself the complete master of the situation. All his life he had given orders to machines, and the fact that this one was unfamiliar was of no importance. For that matter, he had never seen more than a few per cent of the robots that provided his daily needs in Diaspar.

  “Can you speak?” he asked.

  There was silence.

  “Is anyone controlling you?”

  Still silence.

  “Go away. Come here. Rise. Fall.”

  None of the conventional control thoughts produced any effect. The machine remained contemptuously inactive. That suggested two possibilities. It was either too unintelligent to understand him or it was very intelligent indeed, with its own powers of choice and volition. In that case, he must treat it as an equal. Even then he might underestimate it, but it would bear him no resentment, for conceit was not a vice from which robots often suffered.

  Hilvar could not help laughing at Alvin’s obvious discomfiture. He was just about to suggest that he should take over the task of communicating, when the words died on his lips. The stillness of Shalmirane was shattered by an ominous and utterly unmistakable sound— the gurgling splash of a very large body emerging from water.

  It was the second time since he had left Diaspar that Alvin wished he were at home. Then he remembered that this was not the spirit in which to meet adventure, and he began to walk slowly but deliberately toward the lake.

  The creature now emerging from the dark water seemed a monstrous parody, in living matter, of the robot that was still subjecting them to its silent scrutiny. That same equilateral arrangement of eyes could be no coincidence; even the pattern of tentacles and little jointed limbs had been roughly reproduced. Beyond that, however, the resemblance ceased. The robot did not possess— it obviously did not require— the fringe of delicate, feathery palps which beat the water with a steady rhythm, the stubby multiple legs on which the beast was humping itself ashore, or the ventilating inlets, if that was what they were, which now wheezed fitfully in the thin air.

  Most of the creature’s body remained in the water; only the first ten feet reared itself into what was clearly an alien element. The entire beast was about fifty feet long, and even anyone with no knowledge of biology would have realized that there was something altogether wrong about it. It had an extraordinary air of improvisation and careless design, as if its components had been manufactured without much forethought and thrown roughly together when the need arose.

  Despite its size and their initial doubts, neither Alvin nor Hilvar felt the slightest nervousness once they had had a clear look at the dweller in the lake. There was an engaging clumsiness about the creature which made it quite impossible to regard it as a serious menace, even if there was any reason to suppose it might be dangerous. The human race had long ago overcome its childhood terror of the merely alien in appearance. That was a fear which could no longer survive after the first contact with friendly extraterrestrial races.

  “Let me deal with this,” said Hilvar quietly. “I’m used to handling animals.”

  “But this isn’t an animal,” whispered Alvin in return. “I’m sure it’s intelligent, and owns that robot.”

  “The robot may own it. In any case, its mentality must be very strange. I can still detect no sign of thought. Hello— what’s happening?”

  The monster had not moved from its half-raised position at the water’s edge, which it seemed to be maintaining with considerable effort. But a semitransparent membrane had begun to form at the center of the triangle of eyes— a membrane that pulsed and quivered and presently started to emit audible sounds. They were low-pitched, resonant boomings which created no intelligible words, though it was obvious that the creature was trying to speak to them.

  It was painful to watch this desperate attempt at communication. For several minutes the creature struggled in vain; then, quite suddenly, it seemed to realize that it had made a mistake. The throbbing membrane contracted in size, and the sounds it emitted rose several octaves in frequency until they entered the spectrum of normal speech. Recognizable words began to form, though they were still interspersed with gibberish. It was as if the creature was remembering a vocabulary it had known long ago but had had no occasion to use for many years.

  Hilvar tried to give what assistance he could.

  “We can understand you now,” he said, speaking slowly and distinctly. “Can we help you? We saw the light you made. It brought us here from Lys.”

  At the word “Lys” the creature seemed to droop as if it had suffered some bitter disappointment.

  “Lys,” it repeated; it could not manage the “s” very well, so that the word sounded like “Lyd.” “Always from Lys. No one else ever comes. We call the Great Ones, but they do not hear.”

  “Who are the Great Ones?” asked Alvin, leaning forward eagerly. The delicate, ever-moving palps waved briefly toward the sky.

  “The Great Ones,” it said. “From the planets of eternal day. They will come. The Master promised us.”

  This did not seem to make matters any clearer. Before Alvin could continue his cross-examination, Hilvar intervened again. His questioning was so patient, so sympathetic, and yet so penetrating that Alvin knew better than to interrupt, despite his eagerness. He did not like to admit that Hilvar was his superior in intelligence, but there was no doubt that his flair for handling animals extended even to this fantastic being. What was more, it seemed to respond to him. Its speech became more distinct as the conversation proceeded, and where at first it had been brusque to the point of rudeness, it presently elaborated its answers and volunteered information on its own.

  Alvin lost all consciousness of the passage of time as Hilvar pieced together the incredible story. They could not discover the whole truth; there was endless room for conjecture and debate. As the creature answered Hilvar’s questions ever more and more willingly, its appearance began to change. It slumped back into the lake, and the stubby legs that had been supporting it seemed to dissolve into the rest of its body. Prese
ntly a still more extraordinary change occurred; the three huge eyes slowly closed, shrank to pinpoints, and vanished completely. It was as if the creature had seen all that it wished to for the moment, and therefore had no further use for eyes.

  Other and more subtle alterations were continually taking place, and eventually almost all that remained above the surface of the water was the vibrating diaphragm through which the creature spoke. Doubtless this too would be dissolved back into the original amorphous mass of protoplasm when it was no longer required.

  Alvin found it hard to believe that intelligence could reside in so unstable a form— and his biggest surprise was yet to come. Though it seemed obvious that the creature was not of terrestrial origin, it was some time before even Hilvar, despite his greater knowledge of biology, realized the type of organism they were dealing with. It was not a single entity; in all their conversations with it, it always referred to itself as “we.” In fact, it was nothing less than a colony of independent creatures, organized and controlled by unknown forces.

  Animals of a remotely similar type— the medusae, for example— had once flourished in the ancient oceans of Earth. Some of them had been of great size, trailing their translucent bodies and forests of stinging tentacles over fifty or a hundred feet of water. But none of them had attained even the faintest flicker of intelligence, beyond the power to react to simple stimuli.

  There was certainly intelligence here, though it was a failing, degenerating intelligence. Never was Alvin to forget this unearthly meeting, as Hilvar slowly pieced together the story of the Master, while the protean polyp groped for unfamiliar words, the dark lake lapped at the ruins of Shalmirane, and the trioptic robot watched them with unwavering eyes.

  CHAPTER

  13

  The Master had come to earth amid the chaos of the Transition Centuries, when the Galactic Empire was crumbling but the lines of communication among the stars had not yet completely broken. He had been of human origin, though his home was a planet circling one of the Seven Suns. While still a young man, he had been forced to leave his native world, and its memory had haunted him all his life. His expulsion he blamed on vindictive enemies, but the fact was that he suffered from an incurable malady which, it seemed, attacked only Homo sapiens among all the intelligent races of the Universe. That disease was religious mania.

  Throughout the earlier part of its history, the human race had brought forth an endless succession of prophets, seers, messiahs, and evangelists who convinced themselves and their followers that to them alone were the secrets of the Universe revealed. Some of them succeeded in establishing religions that survived for many generations and influenced billions of men; others were forgotten even before their deaths.

  The rise of science, which with monotonous regularity refuted the cosmologies of the prophets and produced miracles which they could never match, eventually destroyed all these faiths. It did not destroy the awe, nor the reverence and humility, which all intelligent beings felt as they contemplated the stupendous Universe in which they found themselves. What it did weaken, and finally obliterate, were the countless religions, each of which claimed with unbelievable arrogance that it was the sole repository of the truth and that its millions of rivals and predecessors were all mistaken.

  Yet, though they never possessed any real power once humanity had reached a very elementary level of civilization, all down the ages isolated cults had continued to appear, and however fantastic their creeds they had always managed to attract some disciples. They thrived with particular strength during periods of confusion and disorder, and it was not surprising that the Transition Centuries had seen a great outburst of irrationality. When reality was depressing, men tried to console themselves with myths.

  The Master, even if he was expelled from his own world, did not leave it unprovided. The Seven Suns had been the center of galactic power and science, and he must have possessed influential friends. He had made his hegira in a small but speedy ship, reputed to be one of the fastest ever built. With him into exile he had taken another of the ultimate products of galactic science— the robot that was looking at Alvin and Hilvar even now.

  No one had ever known the full talents and functions of this machine. To some extent, indeed, it had become the Master’s alter ego; without it, the religion of the Great Ones would probably have collapsed after the Master’s death. Together they had roved among the star clouds on a zigzag trail which led at last, certainly not by accident, back to the world from which the Master’s ancestors had sprung.

  Entire libraries had been written about that saga, each work therein inspiring a host of commentaries until, by a kind of chain reaction, the original volumes were lost beneath mountains of exegesis and annotation. The Master had stopped at many worlds, and made disciples among many races. His personality must have been an immensely powerful one for it to have inspired humans and nonhumans alike, and there was no doubt that a religion of such wide appeal must have contained much that was fine and noble. Probably the Master was the most successful— as he was also the last— of all mankind’s messiahs. None of his predecessors could have won so many converts or had their teachings carried across such gulfs of time and space.

  What those teachings were neither Alvin nor Hilvar could ever discover with any accuracy. The great polyp did its desperate best to convey them, but many of the words it used were meaningless and it had a habit of repeating sentences or whole speeches with a kind of swift mechanical delivery that made them very hard to follow. After a while Hilvar did his best to steer the conversation away from these meaningless morasses of theology in order to concentrate on ascertainable facts.

  The Master and a band of his most faithful followers had arrived on Earth in the days before the cities had passed away, and while the Port of Diaspar was still open to the stars. They must have come in ships of many kinds; the polyps, for example, in one filled with the waters of the sea which was their natural home. Whether the movement was well received on Earth was not certain; but at least, it met no violent opposition, and after further wanderings it set up its final retreat among the forests and mountains of Lys.

  At the close of his long life, the Master’s thoughts had turned once more toward the home from which he had been exiled, and he had asked his friends to carry him out into the open so that he could watch the stars. He had waited, his strength waning, until the culmination of the Seven Suns, and toward the end he babbled many things which were to inspire yet more libraries of interpretation in future ages. Again and again he spoke of the “Great Ones” who had now left this universe of space and matter but who would surely one day return, and he charged his followers to remain to greet them when they came. Those were his last rational words. He was never again conscious of his surroundings, but just before the end he uttered one phrase that had come down the ages to haunt the minds of all who heard it: “It is lovely to watch the colored shadows on the planets of eternal light.” Then he died.

  At the Master’s death, many of his followers broke away, but others remained faithful to his teachings, which they slowly elaborated through the ages. At first they believed that the Great Ones, whoever they were, would soon return, but that hope faded with the passing centuries. The story here grew very confused, and it seemed that truth and legend were inextricably intertwined. Alvin had only a vague picture of generations of fanatics, waiting for some great event which they did not understand to take place at some unknown future date.

  The Great Ones never returned. Slowly the power of the movement failed as death and disillusion robbed it of its disciples. The short-lived human followers were the first to go, and there was something supremely ironic in the fact that the very last adherent of a human prophet was a creature utterly unlike Man.

  The great polyp had become the Master’s last disciple for a very simple reason. It was immortal. The billions of individual cells from which its body was built would die, but before that happened they would have reproduced themselves. At long
intervals the monster would disintegrate into its myriad separate cells, which would go their own way and multiply by fission if their environment was suitable. During this phase the polyp did not exist as a self-conscious, intelligent entity— here Alvin was irresistibly reminded of the manner in which the inhabitants of Diaspar spent their quiescent millenniums in the city’s Memory Banks.

  In due time some mysterious biological force brought the scattered components together again, and the polyp began a new cycle of existence. It returned to awareness and recollected its earlier lives, though often imperfectly since accident sometimes damaged the cells that carried the delicate patterns of memory.

  Perhaps no other form of life could have kept faith so long to a creed otherwise forgotten for a billion years. In a sense, the great polyp was a helpless victim of its biological nature. Because of its immortality, it could not change, but was forced to repeat eternally the same invariant pattern.

  The religion of the Great Ones, in its later stages, had become identified with a veneration of the Seven Suns. When the Great Ones stubbornly refused to appear, attempts were made to signal their distant home. Long ago the signaling had become no more than a meaningless ritual, now maintained by an animal that had forgotten how to learn and a robot that had never known how to forget.

  As the immeasurably ancient voice died away into the still air, Alvin found himself overwhelmed by a surge of pity. The misplaced devotion, the loyalty that had held to its futile course while suns and planets passed away— he could never have believed such a tale had he not seen the evidence before his eyes. More than ever before the extent of his ignorance saddened him. A tiny fragment of the past had been illuminated for a little while, but now the darkness had closed over it again.

  The history of the Universe must be a mass of such disconnected threads, and no one could say which were important and which were trivial. This fantastic tale of the Master and the Great Ones seemed like another of the countless legends that had somehow survived from the civilizations of the Dawn. Yet the very existence of the huge polyp, and of the silently watching robot, made it impossible for Alvin to dismiss the whole story as a fable built of self-delusion upon a foundation of madness.
