The Collected Stories of Arthur C. Clarke (19 page)

The river had already overflowed its banks; somewhere down its course the land had twisted beneath that colossal hammer-blow and the way to the sea was no longer open. Dust was still falling in a fine rain, as it would do for days as Man’s cities and treasures returned to the world that had given them birth. But the sky was no longer wholly darkened, and in the west the sun was settling through banks of angry cloud.

A church had stood here by the river’s edge, and though no trace of the building remained, the gravestones that the years had gathered round it still marked its place. Now the stone slabs lay in parallel rows, snapped off at their bases and pointing mutely along the line of the blast. Some were half flattened into the ground, others had been cracked and blistered by terrific heat, but many still bore the messages they had carried down the centuries in vain.

The light died in the west and the unnatural crimson faded from the sky. Yet still the graven words could be clearly read, lit by a steady, unwavering radiance, too faint to be seen by day but strong enough to banish night. The land was burning: for miles the glow of its radioactivity was reflected from the clouds. Through the glimmering landscape wound the dark ribbon of the steadily widening river, and as the waters submerged the land that deadly glow continued unchanging in the depths. In a generation, perhaps, it would have faded from sight, but a hundred years might pass before life could safely come this way again.

Timidly the waters touched the worn gravestone that for more than three hundred years had lain before the vanished altar. The church that had sheltered it so long had given it some protection at the last, and only a slight discoloration of the rock told of the fires that had passed this way. In the corpse-light of the dying land, the archaic words could still be traced as the water rose around them, breaking at last in tiny ripples across the stone. Line by line the epitaph upon which so many millions had gazed slipped beneath the conquering waters. For a little while the letters could still be faintly seen; then they were gone forever.

Good freed for Iesvs sake forbeare,

To digg the dvst encloased heare

Blest be ye man yt spares thes stones,

And cvrst be he yt moves my bones.

Undisturbed through all eternity the poet could sleep in safety now: in the silence and darkness above his head, the Avon was seeking its new outlet to the sea.

The second of two stories derived from an earlier one, now lost, ‘History Lesson’ is also the first of two stories in which glaciers return to cover the world. In the preface to
Expedition to Earth
, Clarke notes his discovery of a literally chilling phrase in Will and Ariel Durant’s
Story of Civilisation
: ‘Civilisation is an interlude between Ice Ages’, and observes ‘the next one is already overdue; perhaps global warming has arrived just in time to save us.’

No one could remember when the tribe had begun its long journey: the land of great rolling plains that had been its first home was now no more than a half-forgotten dream. For many years Shann and his people had been fleeing through a country of low hills and sparkling lakes, and now the mountains lay ahead. This summer they must cross them to the southern lands, and there was little time to lose.

The white terror that had come down from the poles, grinding continents to dust and freezing the very air before it, was less than a day’s march behind. Shann wondered if the glaciers could climb the mountains ahead, and within his heart he dared to kindle a little flame of hope. They might prove a barrier against which even the remorseless ice would batter in vain. In the southern lands of which the legends spoke, his people might find refuge at last.

It took many weeks to discover a pass through which the tribe and its animals could travel. When midsummer came, they had camped in a lonely valley where the air was thin and the stars shone with a brilliance none had ever seen before. The summer was waning when Shann took his two sons and went ahead to explore the way. For three days they climbed, and for three nights slept as best they could on the freezing rocks. And on the fourth morning there was nothing ahead but a gentle rise to a cairn of grey stones built by other travellers, centuries ago.

Shann felt himself trembling, and not with cold, as they walked towards the little pyramid of stones. His sons had fallen behind; no one spoke, for too much was at stake. In a little while they would know if all their hopes had been betrayed.

To east and west, the wall of mountains curved away as if embracing the land beneath. Below lay endless miles of undulating plain, with a great river swinging across it in tremendous loops. It was fertile land; one in which the tribe could raise its crops knowing that there would be no need to flee before the harvest came.

Then Shann lifted his eyes to the south, and saw the doom of all his hopes. For there, at the edge of the world, glimmered that deadly light he had seen so often to the north—the glint of ice below the horizon.

There was no way forward. Through all the years of flight, the glaciers from the south had been advancing to meet them. Soon they would be crushed beneath the moving walls of ice—

The southern glaciers did not reach the mountains until a generation later. In that last summer, the sons of Shann carried the sacred treasures of the tribe to the lonely cairn overlooking the plain. The ice that had once gleamed below the horizon was now almost at their feet; by the spring it would be splintering against the mountain walls.

No one understood the treasures, now: they were from a past too distant for the understanding of any man alive. Their origins were lost in the mists that surrounded the Golden Age, and how they had come at last into the possession of this wandering tribe was a story that now never would be told. For it was the story of a civilisation that had passed beyond recall.

Once, all these pitiful relics had been treasured for some good reason and now they had become sacred, though their meaning had long been lost. The print in the old books had faded centuries ago, though much of the lettering was still readable—if there had been any to read it. But many generations had passed since anyone had had a use for a set of seven-figure logarithms, an atlas of the world, and the score of Sibelius’s Seventh Symphony printed, according to the flyleaf, by H. K. Chu & Sons at the City of Pekin in the year
AD
2021.

The old books were placed reverently in the little crypt that had been made to receive them. There followed a motley collection of fragments: gold and platinum coins, a broken telephoto lens, a watch, a cold-light lamp, a microphone, the cutter from an electric shaver, some midget radio valves—the flotsam that had been left behind when the great tide of civilisation ebbed for ever. All these were carefully stowed away in their resting-place. Then came three more relics, the most sacred of all because the least understood.

The first was a strangely shaped piece of metal, showing the coloration of intense heat. It was, in its way, the most pathetic of all these symbols from the past, for it told of Man’s greatest achievement and of the future he might have known. The mahogany stand on which it was mounted bore a silver plate with the inscription:

Auxiliary igniter from starboard jet of spaceship

Morning Star
, Earth—Moon,

Next followed another miracle of the ancient science: a sphere of transparent plastic with oddly shaped pieces of metal embedded in it. At its centre was a tiny capsule of synthetic radio-element, surrounded by the converting screens that shifted its radiation far down the spectrum. As long as the material remained active, the sphere would be a tiny radio transmitter broadcasting power in all directions. Only a few of these spheres had ever been made; they had been designed as perpetual beacons to mark the orbits of the Asteroids. But Man had never reached the Asteroids, and the beacons had never been used.

Last of all was a flat circular tin, very wide in comparison to its depth. It was heavily sealed, and rattled when it was shaken. The tribal lore predicted that disaster would follow if it were ever opened, and no one knew that it held one of the great works of art of nearly a thousand years before.

The work was finished. The two men rolled the stones back into place and slowly began to descend the mountainside. Even at the last, Man had given some thought to the future and had tried to preserve something for posterity.

That winter, the great waves of ice began their first assault on the mountains, attacking from north and south. The foothills were overwhelmed in the first onslaught, and the glaciers ground them into dust. But the mountains stood firm, and when the summer came the ice retreated for a while.

So, winter after winter, the battle continued, and the roar of the avalanches, the grinding of rock and the explosions of splintered ice filled the air with tumult. No war of Man’s had been fiercer nor had engulfed the globe more completely than this. Until at last the tidal waves of ice began to subside and to creep slowly down the flanks of the mountains they had never quite subdued; though the valleys and passes were still firmly in their grip. It was stalemate: the glaciers had met their match.

But their defeat was too late to be of any use to Man.

So the centuries passed; and presently there happened something that must occur once at least in the history of every world in the Universe, no matter how remote and lonely it may be—

The ship from Venus came five thousand years too late, but its crew knew nothing of this. While still many millions of miles away, the telescopes had seen the great shroud of ice that made Earth the most brilliant object in the sky next to the Sun itself. Here and there the dazzling sheet was marred by black specks that revealed the presence of almost buried mountains. That was all. The rolling oceans, the plains and forests, the deserts and lakes—all that had been the world of Man was sealed beneath the ice, perhaps for ever.

The ship closed into Earth and established an orbit less than a thousand miles distant. For five days it circled the planet while cameras recorded all that was left to view and a hundred instruments gathered information that would give the Venusian scientists many years of work. An actual landing was not intended; there seemed little purpose in it. But on the sixth day the picture changed. A panoramic monitor, driven to the limit of its amplification, detected the dying radiation of the five-thousand-years-old beacon. Through all the centuries it had been sending out its signals, with ever-failing strength as its radioactive heart steadily weakened.

The monitor locked on the beacon frequency. In the control-room, a bell clamoured for attention. A little later, the Venusian ship broke free from its orbit and slanted down towards Earth—towards a range of mountains that still towered proudly above the ice, and to a cairn of grey stones that the years had scarcely touched.

The great disc of the Sun blazed fiercely in a sky no longer veiled with mist, for the clouds that had once hidden Venus had now completely gone. Whatever force had caused the change in the Sun’s radiation had doomed one civilisation but given birth to another. Less than five thousand years before, the half-savage people of Venus had seen Sun and stars for the first time. Just as the science of Earth had begun with astronomy, so had that of Venus, and on the warm, rich world that Man had never seen, progress had been incredibly rapid.

Perhaps the Venusians had been lucky. They never knew the Dark Age that held Man enchained for a thousand years; they missed the long detour into chemistry and mechanics, but came at once to the more fundamental laws of radiation physics. In the time that Man had taken to progress from the Pyramids to the rocket-propelled spaceship, the Venusians had passed from the discovery of agriculture to antigravity itself—the ultimate secret that Man had never learned.
