Nemesis (54 page)

“That doesn’t necessarily follow,” Yimot said, with a great flurry of his arms. “We don’t have any idea where it is along its orbital path right now, or how long it takes to make one complete circuit around Kalgash. It might be a ten-thousand-year orbit and Kalgash Two could still be heading away from us after an approach in prehistoric times that no one remembers.”

“True,” Beenay admitted. “We can’t really say whether it’s coming or going at the present moment. Not yet, anyway.”

“But we can try to find out,” Faro said. “Thilanda has the right idea. Even though all the numbers check out, we need to see whether Kalgash Two is actually out there. Once we find it we can begin to calculate its orbit.”

“We should be able to calculate its orbit simply from the perturbations it causes in ours,” said Klet, who was the department’s best mathematician.

“Yes,” Simbron put in—she was a cosmographer—“and we can also figure out whether it’s approaching or heading away from us. Gods! What if it’s heading this way? What an amazing event that would be! A dark planetary body cutting across the sky—passing. between us and the suns! Possibly even blotting out the light of some of them for a couple of hours!”

“How strange that would be,” Beenay mused. “An eclipse, I suppose you could call it. You know: the visual effect that occurs when some object gets between a viewer and the thing he’s looking at. But could it happen? The suns are so huge—how could
Kalgash Two actually conceal one of them from view?”

“If it came close enough to us it might,” Faro said. “Why, I could imagine a situation in which—”

“Yes, work out all possible scenarios, why don’t you?” Athor interjected suddenly, cutting Faro off with such brutal abruptness that everyone in the room turned to stare at him. “Play with the idea, all of you. Push it this way and that, and see what you get.”

Suddenly he couldn’t bear to sit here any longer. He had to get away.

The exhilaration he had felt since putting the last piece into place had abruptly deserted him. He felt a terrible leaden weariness, as though he were a thousand years old. Chills were running along his arms down into his fingers, and something was squirming frantically in the muscles of his back. He knew that he had pushed himself beyond all endurance now. It was time for younger workers to relieve him of this enterprise.

Rising from his chair before the screens, Athor took one uncertain reeling step toward the middle of the room, recovered himself before he could stumble, and walked slowly and with all the dignity he could muster past the observatory staff. “I’m going home,” he said. “I could use some sleep.”

Beenay said, “Am I to understand that the village was destroyed by fire
nine times in a row
, Siferra? And they rebuilt it every time?”

“My colleague Balik thinks there may be only seven villages piled up in the Hill of Thombo,” the archaeologist replied. “And he may be right, actually. Things are pretty jumbled down toward the lowest levels. But seven villages, nine villages—no matter how many it is exactly, it doesn’t change the fundamental concept. Here: look at these charts. I’ve
worked them up from my excavation notes. Of course what we did was just a preliminary dig, a quick slice through the whole hill, with the really meticulous work left for a later expedition. We discovered the hill too late in our work to do anything else. But these charts’ll give you an idea. —You aren’t going to be bored, are you? All this stuff does interest you, doesn’t it, Beenay?”

“I find it completely fascinating. Do you think I’m so totally preoccupied with astronomy that I can’t pay attention to any of the other disciplines? —Besides, archaeology and astronomy sometimes go hand in hand. We’ve learned more than a little about the movements of the suns through the heavens by studying the ancient astronomical monuments that you people have been digging up here and there around the world. Here, let me see.”

They were in Siferra’s office. She had asked Beenay to come there to discuss a problem which she said had unexpectedly arisen in the course of her research. Which puzzled him, because he didn’t immediately see how an astronomer could help an archaeologist in her work, despite what he had just said about archaeology and astronomy sometimes going hand in hand. But he was always glad to have a chance to visit with Siferra.

They had met initially five years before, when they had worked together on an interdisciplinary faculty committee that was planning the expansion of the university library. Though Siferra had been out of the country most of the time since then doing field work, she and Beenay did enjoy meeting for lunch now and then when she was there. He found her challenging, highly intelligent, and abrasive in a refreshing sort of way. What she saw in him he had no idea: perhaps just an intellectually stimulating young man who wasn’t involved in the poisonous rivalries and feuds of her own field and had no apparent designs on her body.

Siferra unfolded the charts, huge sheets of thin parchmentlike paper on which complex, elegant diagrams had been ruled with pencil, and she and Beenay bent forward to examine them at close range.

He had been telling the truth when he said he was fascinated by archaeology. Ever since he’d been a boy, he had enjoyed reading the narratives of the great explorers of antiquity, such men as Marpin, Shelbik, and of course Galdo 221. He found the remote past nearly as exciting to think about as the remote reaches of interstellar space.

His contract-mate Raissta wasn’t greatly pleased by his friendship with Siferra. She had rather testily implied, a couple of times, that it was Siferra herself that fascinated him, not her field of research. But Beenay thought Raissta’s jealousy was absurd. Certainly Siferra was an attractive woman—it would be disingenuous to pretend otherwise—but she was relentlessly nonromantic and every man on campus knew it. Besides, she was something like ten years older than Beenay. Handsome as she was, Beenay had never thought of her with any sort of intimate intentions.

“What we have here, first, is a cross section of the entire hill,” Siferra told him. “I’ve plotted each separate level of occupation in a schematic way. The newest settlement’s at the top, naturally—huge stone walls, what we call the cyclopean style of architecture, typical of the Beklimot culture in its mature period of development. This line here in the level of the cyclopean walls represents a layer of charcoal remains—enough charcoal to indicate a widespread conflagration that must have utterly wiped the city out. And here, below the cyclopean level and the burn line, is the next oldest settlement.”

“Which is constructed in a different style.”

“Exactly. You see how I’ve drawn the stones of the walls? It’s what we call the crosshatch style, characteristic
of the early Beklimot culture, or perhaps the culture that developed into Beklimot. Both these styles can be seen in the Beklimot-era ruins that surround the Hill of Thombo. The main ruins are cyclopean, and here and there we’ve found a little crosshatch stuff, just a mere outcropping or two, which we call proto-Beklimot. Now, look here, at the border between the crosshatch settlement and the cyclopean ruins above it.”

“Another fire line?” Beenay said.

“Another fire line, yes. What we have in this hill is like a sandwich—a layer of human occupation, a layer of charcoal, another layer of human occupation, another layer of charcoal. So what I think happened is something like this. During the time of the crosshatch people there was a devastating fire that scorched a pretty good chunk of the Sagikan Peninsula and forced the abandonment of the Thombo village and other crosshatch-style villages nearby. Afterward, when the inhabitants came back and began to rebuild, they used a brand-new and more elaborate architectural style, which we call cyclopean because of the huge building-stones. But then came
another
fire and wiped out the cyclopean settlement. At that point the people of the area gave up trying to build cities on the Hill of Thombo, and this time when they rebuilt they chose another site nearby, which we term Beklimot Major. We’ve believed for a long time that Beklimot Major was the first true human city, emerging from the smaller crosshatch-type proto-Beklimot-period settlements scattered all around it. What Thombo tells us is that there was at least one important cyclopean city in the area before Beklimot Major existed.”

“And the Beklimot Major site,” Beenay said, “shows no trace of fire damage?”

“No. So it wasn’t there when the city on top of Thombo was burned. Eventually the whole Beklimot culture collapsed and Beklimot Major itself was abandoned,
but that was for other reasons having to do with climatic shifts. Fire had nothing to do with it. That was perhaps a thousand years ago. But the fire that wrecked the topmost Thombo village seems to have been much earlier than that. I’d guess about a thousand years earlier. The radiocarbon dates from the charcoal samples will give us a more precise figure when we get them from the lab.”

“And the crosshatch settlement—how old is that?”

“Orthodox archaeological belief has been that the fragmentary crosshatch structures we’ve found here and there on the Sagikan Peninsula are only a few generations older than the Beklimot Major site. After the Thombo excavation, I don’t think so. My guess is that the crosshatch settlement on that hill is two thousand years older than the cyclopean buildings on top of it.”

“Two
thousand
—? And you say there are other settlements below that one?”

“Look at the chart,” Siferra said. “Here’s number three—a kind of architecture we’ve never seen before, nothing at all like crosshatch work. Then another burn line. Settlement number four. And a burn line. Number five. A burn line. Then numbers six, seven, eight, and nine—or, if Balik’s reading is correct, just numbers six and seven.”

“And each one destroyed by a great fire! That seems pretty remarkable to me. A deadly cycle of destruction, striking again and again and again in the same place.”

“The remarkable thing,” said Siferra in a curiously somber tone, “is that each of these settlements appears to have flourished for approximately the same length of time before being destroyed by fire. The layers of occupation are quite extraordinarily similar in thickness. We’re still waiting for the lab reports, you understand. But I don’t think my eyeball estimate is very far off. And Balik’s figures are the same as mine. Unless we’re comoletelv mistaken, we’re
looking at a minimum of fourteen thousand years of prehistory in the Hill of Thombo. And during those fourteen thousand years the hill was periodically swept by massive fires that forced its abandonment with clockwork regularity—one fire every two thousand years, just about exactly!”

“What?”

A shiver traveled along Beenay’s spine. His mind was beginning to leap to all manner of improbable and disturbing conclusions.

“Wait,” Siferra said. “There’s more.”

She opened a drawer and took out a stack of glossy photographs.

“These are pictures of the Thombo Tablets. Mudrin 505 has the originals—the paleographer, you know. He’s been trying to decipher them. They’re made of baked clay. We found these three in Level Three, and these in Level Five. They’re both written in extremely primitive scripts, and the writing on the older ones is so ancient that Mudrin can’t even make a start on them. But he’s been able very tentatively to puzzle out a couple of dozen words from the Level Three tablets, which are written in an early form of the Beklimot script. So far as he can tell at this point, they’re an account of the destruction of a city by fire—the work of angry gods who periodically find it necessary to punish mankind for wickedness.”

“Periodically?”

“That’s right. Does it begin to sound familiar?”

“The Apostles of Flame! My God, Siferra, what have you stumbled on here?”

“That’s what I’ve been asking myself since Mudrin brought me the first sketchy translations.” The archaeologist swung around to face Beenay, and for the first time Beenay saw how bleary her eyes were, how tense and drawn her face. She looked almost distraught. “Do you see now why I asked you to come here? I can’t talk about this with anyone in the department. Beenay, what am I going to do? If any of
this becomes public, Mondior 71 and his whole crazy crew will proclaim it from the rooftops that I’ve discovered firm archaeological proof of their crackpot theories!”

“You think so?”

“What else?” Siferra tapped the charts. “Here’s evidence of repeated fiery destruction at two-thousand-year intervals, roughly, over a period of many thousands of years. And these tablets—the way it looks now, they might actually be some sort of prehistoric version of the Book of Revelation. Taken together they provide, if not actual confirmation of the rantings of the Apostles, then at least a solid rational underpinning for their whole mythology.”

“But repeated fires at a single site don’t prove that there was worldwide devastation,” Beenay objected.

“It’s the periodicity that worries me,” said Siferra. “It’s too neat, and too close to what Mondior’s been saying. I’ve been looking at the Book of Revelation. The Sagikan Peninsula is a holy place to the Apostles, did you know that? The sacred site where the gods formerly made themselves visible to humanity, so they say. And therefore it stands to reason—listen to me, it stands to
reason
,” she said, laughing bitterly—“that the gods would preserve Sagikan as a warning to mankind of the doom that will come again and again if we don’t alter our wicked ways.”

Beenay stared at her, stunned.

He knew very little about the Apostles and their teachings, really. Such pathological fantasizing had never held any interest for him, and he had been too busy with his scientific work to pay heed to Mondior’s windy apocalyptic prophecies.

But now the memory of the conversation he had had some weeks before with Theremon 762 at the Six Suns Club burst with furious impact into his consciousness. “
Not the first time the world has been destroyed … The gods have deliberately made mankind imperfect and given us a single year, one of
their years, not ours, in which to shape up. That’s called a Year of Godliness, and it’s exactly 2,049 of our years long.
