But no, away with such thoughts; he must begin to practice his humility. He called to Will to fetch him his writing materials from the coach and then he went out through the broken gate to sit alone in the sun beside the road, with one tumbled block of stone for a bench and another for a table. He might as well put his time to use, start writing his statement of recantation to present during the trial.

Of course, the accused was not supposed to know why he had been summoned. Probably the Defenders' first question would be whether or not he had any idea of what he had been charged with. No doubt such an opening sometimes brought unsuspected crimes bursting to light from guilty lips, but in Vincento's case there could hardly be any doubt of the reason for his summons. It had been fifteen years since Belam's warning injunction, which Vincento himself had since managed almost to forget. Other scholars before and since had talked of the heliocentric hypothesis with impunity and had used it in their published calculations. But when the Defenders' summons came, Vincento realized that he had bitterly antagonized men who were in high places and who never forgot anything.

The first paper he pulled from his portable escritoire was the old letter of injunction from Defender Belam. Involuntarily, Vincento's eye went at once to the words, "no proof of our globe's motion exists, as I believe, since none has been shown to me."

No proof. Vincento wiped at his forehead with a tremulous hand. Now, with mortal fear to enforce bleak clarity of thought, he could see that the arguments he had conjured from tides and sunspots really proved nothing at all about the motions of sun and planets. The truth about those motions had become apparent to him before he had ever thought of the need for proving it. He had looked long through telescopes and he had thought long and deeply about what he saw. With eyes and mind he had weighed the sun, he had grasped at stars and planets and comets, and truth had come through some inward door, like a revelation.

His enemies who cried him down were, of course, far lesser men than he. They were stupid and blind in their refusal, or their inability, to see what he showed them as the truth. And yet he knew that those who were to sit as his judges were shrewd enough logicians when they set themselves to think within their formal rules. If only there were some firm proof, simple and incontrovertible, that he might set before them . . . oh, what would he not give for that! His mind ached, his fists clenched, his very guts contracted at the thought. If he had one solid simple proof he would risk all, he would dare anything, to confront and confound his enemies with it, to rub their long arrogant noses in the truth!

But since in fact he had nothing to support this mood of glorious defiance, it soon pa.s.sed. The truth was, he was old and afraid and he was going to recant.

Slowly he got out pen and ink and blank paper; slowly he began his first draft. From time to time he paused, sitting with closed eyes in the sun, trying not to think.

Derron counted seven soldiers around the breakfast fire, and he found each of them overjoyed to accept a swallow of brandy from his traveling flask and willing enough to talk. No, there was no one he had not seen in the monastery or the cathedral, or anywhere nearer than the town across the river. Not that they knew of, and they would know.

When he was alone in the privy a few minutes later, Derron did some subvocal mumbling. "Operations?"

"Time Ops here."

Maybe the Commander never had to sleep, but Derron himself was sufficiently tired and strained to dispense with military courtesy. "Count the lifelines here again. I make it just thirteen of us. If you can make it twelve, then one of my smiling companions has clockwork for guts. But if you come out with fourteenagain, then either there's some bandit or deserter lurking in a corner I haven't seen or you're misreading your screens. I think that dotted line at least is a mistake in interpretation; I consider it unlikely that any of us here is pregnant, since we're all men."

"We'll recheck right away. You know how tricky screen interpretation can be sometimes." Time Ops'

tone was quietly apologetic, which was somehow more disturbing to Derron than a chewing-out would have been. It meant that his position here was now considered so vital that Operations would bend every effort to make things go more smoothly for him.

The soldiers, after finishing their morning meal and emptying Derron's brandy flask, had for the most part settled down to serious loafing. Rudd, Vincento's coachman, was leading his load-beasts forth in search of gra.s.s. Following the animals through the gate, Derron located Vincento, sitting peacefully alone and apart with his writing materials. Well and good.

Remembering his imaginary load-beast and sulky, Derron put on an exasperated expression and strolled along the road toward the ruined bridge, scanning the fields in all directions as if in search of his missing property.

At the bridge-stump were the two friars, gray cowls thrown back from their unremarkable heads.

Judging by their gestures and a word or two that floated Derron's way, they were talking of ways in which the bridge might someday be rebuilt. Derron knew that within a year or two there would indeed be new arches of stone spanning the river here. And those arches would still be standing solidly more than three hundred years later, when a young postgraduate history student would come striding over them on a hiking tour, the girl he loved striding just as eagerly beside him. Both of them would be enthusiastic about seeing for the first time the ancient town and the famed cathedral of Oibbog. . . . The river would look much different then, gentler, of course, and there would be more trees along its banks. While the stones of the ancient Empire road would still look much the same . . .

"May the Holy One give you a good day, esteemed sir!" It was the stouter of the two friars whose voice broke in upon Derron's reverie.

The interruption was welcome. "Good day to you also, reverend Brothers. Does the river still rise?"

The thinner friar had a loving face. In hands that seemed all bone and tendon, he was weighing a small chunk of masonry, as if he meant to start this minute to rebuild the bridge. "The river falls now, sir. How does the course of your life go, up or down?"

The falsehood about beast and buggy seemed dreary and unnecessary. "That can hardly be an easy question for any man to answer."

Derron was spared any further probing for the moment, as the attention of both friars had been distracted. Seven or eight of the local peasantry had materialized out of mud and distance and were plodding their barefoot way along the drying bank of the torrent toward the bridge-stump. One man walking in front of the others proudly swung a string of large and silvery fish, fresh enough to be still twitching and twisting.

A few paces away from the edge of the pavement, the peasant halted. Together they bowed rather perfunctorily in Derron's direction; he was not dressed finely enough to overawe anyone and he was obviously not the person the peasants had come to see.

The man who carried the fish began talking to the friars, in a low tone at first but raising his voice as the others began almost at once to interrupt him. In a few moments they were all squabbling over who had the right to speak first and whose was the right of disposal of the fish. They had come to strike a bargain.

Would the holy brothers accept the biggest and freshest of this fine catch ("From me!" "No, fromme, Holy Brother, it was my fish-line!") and in return say some potent prayers for the giver's crops?

Derron turned away from what promised to become a nasty quarrel among the peasants, to see that Vincento was still sitting alone. And it was then that the full sunlit view of the Cathedral of Oibbog caught him almost by surprise.

The narrowed tip of the central spire held its gilded symbolic wedge two hundred and sixty feet above the flattened hilltop. The stones of tower and wall, of arch and flying b.u.t.tress, were rich clear gray, almost shining in the morning light. Inside, he knew, the stained gla.s.s windows along the eastern wall would be like living flame. If fragile gla.s.s and spire had risen from the dust, then surely she too must be alive, not only alive but somewhere near where he might reach her. At the moment the resurrected reality before him held more conviction than any rein of logic. At any second now, her voice might call to him, he might be able to reach out and touch . . .

There was a splash nearby. The stout friar was wearing a caricature-expression of anger, disappointment, and surprise, while the thinner one stood with a hand stretched out over the water. A big fish now jumped and splashed again; one of the slippery catch had evidently escaped.

. . . touch her warm and living skin. Now even a detail that he had somehow forgotten, the way her hair moved sometimes in the wind, came back to him with the visual clarity of something seen only a minute ago.

Derron's feet took him away from the bridge-stump and back along the road. He noted dutifully with half his mind that Vincento still sat alone in the sun. But Derron did not go back to the monastery. The hill raised the mighty cathedral before him, and he began steadily to climb.

Brother Jovann kept looking sadly at the peasants, even as he seemed to address his words to the splasher in the water. "Brother Fish, I have set you at liberty not because we do not need food, but so you may be able to praise G.o.d, who sends all blessings-the fish to the angler and freedom to the fish."

Sorrowfully, Jovann shook his head at the peasants, "We men so often forget to give thanks when they are due, so often we spend our energy instead in trying to get ahead of one another!"

The fish splashed, and leaped, and splashed again. It was as if the pain of the hook, or the time spent gilling air-or something else-had driven it quite mad.

Jovann looked down with new distress upon this watery uproar. "Be still now, Brother Fish! Enough!

Live in the water, not the painful air. Give praise and thanks as a fish may naturally do!"

The splashing stopped. The last ripples and foam were swept away downstream.

Silence hung in the air. Every peasant's hands were raised in the wedge-sign, and they darted their eyes at one another as if they would have liked to take to their heels in flight, but did not dare. Brother Saile was gaping as blankly as any of the fish, while he swung his eyes from Jovann to the river and back again.

Jovann beckoned Saile away and said to him, "I am going apart for an hour, to pray to the Holy One to cleanse me of anger and pride. And also for these poor men's crops. Do you likewise." And Saile was left still staring, as Jovann walked slowly away alone, on up the road toward the monastery's gate.

As Derron climbed the steps that switchbacked up the face of the cathedral hill, the irrational sense of his love's presence faded, leaving him with only the bitter certainty of her permanent loss. It crossed his mind that at this moment in time her genes were scattered in the chromosomes of some two thousand ancestors. That was as close as he could come to her today, the closest he would ever be able to come.

He knew that a solid palisade of paradox-loops would forever bar him from revisiting the days of her life, what he thought of as the time of his own youth.

The truth was that he had never forgiven her for dying, for being helplessly killed with all the other millions, for her crime of emptying his world. Maybe forgiving her was what he had come back to Oibbog to try to do. So, he told himself, do it. Do whatever is necessary to end it now, today. Get it all over with somehow, out of your system once and for all, so that you can be some good to yourself and to someone else again.

By now the roof of the monastery had fallen below the level of his climbing feet. When he looked back he saw the valley spreading out, flood-ravaged now and wilder in its beauty than he remembered it, but still essentially the same. At a turn on the stairs he pa.s.sed a sapling and with a pang of realization he knew that in three hundred years this slender stem would be a gnarled and mighty trunk, with heavy branches to shade out the summer sun. And beside it he would stand with her, looking out over the valley, the two of them choosing a hill for themselves-that hill there, oh G.o.d, though no trees grew on it now!-where one day they intended to build their home and raise the pair of kids they meant to have.

He kept right on climbing. He felt that if he stopped here now he might never go on, and going on was necessary. Now at last his eyes rose above the level of the paved s.p.a.ce before the main entrance of the cathedral. His memory recognized the very pattern of the paving stones here, where her feet and his would one day stand. If he stood here now, looking straight ahead at remembered hedges and statues, his vision bounded by the gray stone of the cathedral's front-why, for all that he could see or hear, holiday and youth and love might still be true, war and grief no more than bad dreams pa.s.sing.

The twigs of the hedges were green again, with rain and late spring sunshine. But her voice was not to be heard here, nor would he ever again feel her touch, though he were to stand here till he fell. And for a moment he thought he might be going to fall, or to kneel and pray, or to cry aloud, because the knowledge of her pa.s.sing from him was almost too much-but then, at long, long last, that knowledge could be accepted.

The process of acceptance was not over in an instant, but once it had fairly begun he knew he was not going to collapse. His eyes were none too clear, but he was not going to weep. He was just going to stand here and go on living.

No, he was not finished yet. To complete the process of acceptance and release he had still to go into the building, where he had spent a morning helping her photograph the stained gla.s.s. He remembered wishing aloud at that time that the supposed Author of the universe would come out of hiding and make an appearance in this, supposedly His temple; because the young historian had a few sharp questions that he wanted to ask. Questions having to do with the unnecessary amount of injustice in the world.

The great door was just as solidly hung as Derron remembered it. He wondered briefly if a wooden door in steady use might last three hundred years. No matter. He tugged it open, hearing the booming reverberation of the broken closure come back with repet.i.tions from the building's cavernous interior.

Just then it crossed Derron's mind that his traveler's staff with all its weaponry was resting back in his monastery cell. But that was no matter; immediate violence from the berserker was not a danger.

He went in and paced down the center of the nave, which was only about thirty feet wide between the rows of columns that divided it from the side aisles, but enormous in its other dimensions-three hundred feet long, the keystones of its arches a hundred feet above the floor. There seemed room in here for G.o.d and berserker both to hide, with plenty of corners left to conceal some deserter or pregnant waif whose lifeline might be showing up to confuse Operations.

Along the eastern wall the stained-gla.s.s windows flamed. Centuries of candle smoke had not yet darkened the high arches. Most of the cathedral had been built during the last generation; in fact, construction had not been quite completed when this latest war had resulted in the workmen being ordered or frightened off the job. Much scaffolding still surrounded columns and clung to walls, here and there festooned with the workmen's abandoned ropes and cables, which were as steady in the motionless air as if carved from stone themselves. A few abandoned tools were very slowly gathering dust where they had been set down.

Whether because of the combatants' reverence or superst.i.tious fear, or only through chance, war had not trampled here. Even the stained gla.s.s was all intact, splintered only by the sun coming in to fire the mild gloom with richness. The wide steps that led to side chapels, and most of the paving of the nave, were no more than a century old, still flat and practically unworn; three centuries and more of random footsteps would be required to shape them into standard distribution curves.

As Derron approached the center of the building, where nave and transepts intersected, a movement caught the corner of his eye. One of the friars, hood worn over his head here in G.o.d's house, was approaching him down a side aisle.

Derron stopped, nodding politely. "Reverend Brother." And then it struck him as odd that one of the men he had left down at the bridge should have hurried here ahead of him. Peering closely, he saw that the face beneath the cowl was not quite a face. And the hands reaching out to grab him as the figure shot forward were dummy flesh, split open now to show the steel claws.

The leaner of the friars had come dragging along, head bowed, up the road from the bridge. He pa.s.sed the monastery's gateway, and Vincento was just thinking with some relief that the man was going right on by him, when at the last moment the friar appeared to become aware of Vincento and, after a little startled pause, changed course and came toward him.

He stopped a couple of paces away, smiling now, a gentle and bedraggled figure. "G.o.d will reward you, Vincent, for providing my companion and me with food."

"G.o.d knows I have some need of His favor, Brother," Vincento answered shortly. He supposed the mendicant had learned his given name from Rudd or Will. Curiously, he did not feel offended by the familiar form of address; the dusty beggar before him seemed, like an infant, beneath any question of status.

But Vincento remained wary. It was just possible that this friar was one of the Defenders' agents.

The friar was looking at the papers spread out before Vincento as he might have regarded some friend's unbandaged wound. "Vincent, why do you waste your mind and soul in all these struggles and disputes?

Their outcome does not matter, really. But one thing matters, and that is the love of G.o.d."

The mad innocent sincerity of these words all but wiped away Vincento's suspicions and could provoke him to nothing stronger than a smile. "It seems you have taken the trouble to learn something of my affairs. But, reverend Brother, what do you really understand of my disputes and why I have them?"

The friar drew back with a little quiver of distaste. "I do not understand them. I do not wish to; it is not my way."

"Then, Brother, pardon me, but it seems to me you should not lecture on what you do not understand, nor stand here disputing with me as to why I have disputes."

The friar accepted the rebuke so meekly that Vincento felt a momentary pang of something like regret for having spoken it. And with that the dispute between them, if one could really call it that, was over, Vincento having scored his point with the ease of an armored knight knocking down a child.

The friar did not turn away before he had raised his hands in blessing and murmured a few words that were not addressed to Vincento. Then he departed at once, walking slowly on along the road-once hesitating as if on the point of turning back, then going on. It crossed Vincento's mind that he had once again won an argument and perhaps lost something else-though what it was one lost on these occasions he could not exactly say. He almost called after the man, feeling an impulse to try to reach across the gap between them. But he did not call. Really, he thought, we have nothing to say to each other.

Now that he had been distracted from the humiliating task of writing his recantation, he did not want to take it up again. And so Vincento summoned Will, gave him the escritoire and papers to take in charge, and then turned his own steps restlessly upward in the fine sunlight.

Thinking it over now, he decided that the meeting supposedly arranged in the cathedral was most probably a snare of the Defenders-or more likely, of some of Vincento's enemies, religious or laymen, who would be eager to trick him into some compromising utterance or behavior on the eve of his trial.

Very well, let them try. He would see through the scheme, whatever it was, before they had gotten very far with it. He might be able to turn the tables on them completely. Vincento might fear men who overmatched him in power, but he knew full well that none could overmatch him in intelligence.

He was patient with his old legs, resting them for a single breath after every two or three steps, and so they served him well enough on the climb. After a longer pause for rest at the top of the stairs, he entered at the cathedral's main door and tugged it firmly closed behind him. He devoutly hoped that no one was going to meet him simply to offer sympathy. A sympathizer was at best a secret gloater, having always at least some implied claim to be the equal-more like the superior!-of the one he supposedly was trying to console. Pah!

Vincento strolled through the nave, a stone-sealed s.p.a.ce too vast to give the least sense of confinement.

To his right and left, the vault-supporting columns towered in their parallel rows. Distance diminished the apparent s.p.a.ce between each column and the next, until at fifty paces ahead of him each row became opaque as a wall. No matter where a man stood inside this unpart.i.tioned s.p.a.ce, half of it would always be blocked from his view-more than half, if one counted the areas of the transept arms and the chapels.

When he reached the appointed meeting place, the crossways of nave and transepts, Vincento could look directly up nearly two hundred feet into the shadowed interior of the temple's mighty central spire.

There were workmen's platforms even there, reached by ladders mounting from the clerestory level, which in turn must be accessible by some stair coiling up within the wall from the level of the floor Vincento stood upon.

In this temple, built in the grand old style, there were no chandeliers, and no breezes to swing them if they had existed. If in Vincento's youth this had been his parish house of worship, he would have had to begin to work out the laws of pendulums somewhere else, and not during a drowsy Sabbath sermon.

A single cable of great length descended thinly from the uttermost dark interior of the spire. Vincento's eye followed this cable down, to discover that there was a pendulum here after all, at least in potential.

For bob, there hung on the end of the long cable a ball of metal that would be as heavy as a man. This weight was pulled to one side, held by the merest loop of cord to one of the four thick columns that stood at the corners of the nave-transept intersection.

Looking up and down, up and down again, tended to make an old man dizzy. Vincento rubbed his neck.

But there was an offense to logic here that was beyond his power to ignore. What use could the builders have had for such a patriarch of pendulums?

Itcould, he supposed, be something that they swung when hard stone and mortar had to be demolished-but that was hardly a satisfactory explanation. And if it was only a plumb line, why so weighty? A few ounces of lead would serve that purpose just as well.

Whatever they had intended or used it for, itwasa pendulum. The restraining tether of cord, with its single knot, looked insubstantial. Vincento thrummed the taut little cord with his finger, and the long, lone cable gently whipped and swayed. The ma.s.sive weight made little bobbing motions, dipping like a ship at anchor.

The oscillations quickly died away, the stillness of the cathedral soon regained ascendancy. Once more cord and cable and bob were as steady as the stone columns in the still gray air. The pendulum-ship was drydocked.

Set sail, then! On impulse Vincento tugged once at the end of the restraining cord. And with startling ease the knot dissolved.

Starting from rest, the weight for a moment seemed reluctant to move at all. And even after it had undeniably begun its first swing, still it moved so slowly that Vincento's eye went involuntarily racing once more up into the shadows of the spire, to see how it was possible that mere length of cord should so delay things.

A man might have counted four without haste before the weight for the first time reached the center, the low point, of its swing. Almost touching the floor, it pa.s.sed that center in a smooth fast rush and immediately began to slow again, so that it needed four more counts to climb the gentle gradient of the far half of its arc. Then the weight paused for an unmeasurable instant, not quite touching the column at the opposite corner of the crossways, before it crept into its returning motion.

Majestically the bob went back and forth, holding its cable taut, describing a perfect arc segment about ten yards in length. Vincento's eye could find no diminution in the amplitude of the first half-dozen swings.

He supposed that a weight so heavy and so freely suspended as this might continue to oscillate for many hours or even for days.

Wait, though. Here was something. Vincento squinted at the pendulum through one swing. Then, leaning against the column it had been tethered to, and holding his head motionless, he watched the pendulum's swing end-on for another half-dozen cycles.

What was it he had come in here for? Oh, yes, someone was perhaps going to meet him.

But this pendulum. He frowned at it, shook his head and watched some more. Then he started to look around him. He was going to have to make sure of something he thought he saw.

Some workmen's sawhorses were standing not far away. He dragged a pair of these to where he wanted them, so that the plank he now took up and set across them lay beneath the end of the pendulum's arc and perpendicular to that arc's direction. On the bottom of the swinging weight he had noticed a projection like a small spike: whatever it had been meant for, it would serve Vincento's present purpose well. He laid a second plank atop the first, and slightly readjusted the position of his whole structure, in careful increments. Now on each swing the spike pa.s.sed within an inch of the topmost board.

He would make marks upon the board . . . but no, he could do better. Somewhere in here he had seen sand. Yes, piled in a mixing trough, there by the entrance to the first side chapel. The sand was satisfactorily damp from the long spell of wet weather; he brought handfuls of it and dumped them on his upper board. Along several feet of the board's length he patted and built the sand into a tiny wall, an inch or two high and just thick enough to stand. Then, in an interval between swings, he slid that upper board just slightly forward, taking his sand wall into the edge of the pendulum's arc.

A neatly designed experiment, he thought with satisfaction. On its first return, the moving spike notched his little sand fence delicately, tumbling a tiny clot of grains down the minute slope. Then the weight pulled its taut cable away again, taking another slow nibble of eternity.

Vincento held his eyes from blinking as he watched the pendulum's return. Holding his breath too, he could now hear for the first time the faint ghostly hissing of the swing.

The spike as it moved back to the wall of sand made a new notch, though one contiguous with the first.

Then the weight once more departed, in a movement huge and regular enough to be the cathedral's stately pulse.

And sixteen seconds later the third notch was new again, by the same margin and in the same direction as the second. In three vibrations the plane of the pendulum had shifted its extremity sideways by half a finger-width. His eyes had not deceived him earlier; that plane was slowly and regularly creeping clockwise.

Might this effect be due to some slow untwisting of the cable? Then it should soon reverse itself, Vincento thought, or at least vary in amplitude. Again he stared up into the high shadows, oblivious of his aching neck.
