Two weeks after the formulation of that law the book was finished. He set about the printing at once, in a kind of panic, as if fire or flood, his greatest fears, or some other hobgoblin, might strike him down before he could make public his testament. Besides, the printing was a kind of work, and how could he simply stop? The trajectory he had long ago entered on would take time to run down, would sweep him through further books, the scrag-ends of his career. And even if he had been capable of rest, rest was not permissible, for then he would have had to face, in the dreadful stillness, the demon that has started up at his back, whose hot breath was on his neck.
For years the
World Harmony
had obsessed him, a huge weight pinning him down; now he was aware of a curious feeling of lightness, of levity almost, as if he had drunk again a dose of Wincklemann's drugged wine. That was the demon. He recognised it. He had known it before, the selfsame feeling, when, in the
Astronomia nova,
he had blithely discarded years of work for the sake of an error of a few minutes of arc, not because he had been wrong all those years-though he had-but in order to destroy the past, the human and hopelessly defective past, and begin all over again the attempt to achieve perfection: that same heedless, euphoric sense of teetering on the brink while the gleeful voice at his ear whispered
jump.

Her and far less inviting precipices appeared under his feet. The world that once had seemed so wide was becoming narrower daily. The Palatinate's army had been crushed in the battle of Weisser Berg and Bohemia regained by the Catholics, but the war of the religions still raged. The Empire was ablaze and he was on the topmost storey. He could hear the flames roaring behind him, the crash of masonry and splintering timber as another staircase gave way. Before him there was only the shivered window and the sudden chill blue air. When in the autumn of 1619 the Elector Frederick and his wife Princess Elizabeth entered Prague to accept the crown offered him by the Bohemian Protestants, the
World Harmony
had been on the presses, and Kepler had had time to suppress only in a few final copies the dedication to James of England, the Princess's father. He had not needed that connection to mark him out as suspect. Even his attacks on the brotherhood of the Rosy Cross, and his dispute with the English Rosicrucian Robert Fludd, had won him no praise: the imperial parties, so he heard, were asking what he had to hide, that he should flaunt this too enthusiastic loyalty to his Catholic Emperor Ferdinand. He despaired, he was no good at politics. He was not even sure any longer who was fighting whom in the war. The Bohemian barons had not accepted the defeat of Weisser Berg, but they were a local disturbance: now there was talk of French and even Danish involvement. Kepler was baffled. Could these far-off kingdoms really care so much for religion and the fate of little Bohemia? It must be all a conspiracy. The Rosicrucians were to blame, or the Vatican.
Presently, as he knew it would, the old wheel turned: all Lutherans were ordered out of Linz. As the Emperor's mathematician, in title at least, Kepler could hope for immunity. He gave up his pilgrimages to Wincklemann's deserted shop, and stayed away from religious services. But the invisible plotters would not be thus easily put off. His library was confiscated by the Catholic authorities. He bitterly admired the accuracy of their aim; it was a hard blow to bear. And then, it was almost comic, Lutheranism threw up a tormentor of its own in the shape of Pastor Hitzler. Kepler felt himself backed into a corner, an old, puzzled rat.
The public turmoil was matched in the darkness of his heart, where a private war was raging. He could not tell what was the cause of battle, nor what the prize that was being fought for. On one side was all that he held precious, his work, his love for wife and children, his peace of mind; on the other was that which he could not name, a drunken faceless power. Was it still, he wondered, the demon that had risen up out of the closing pages of the
Harmonia mundi,
grown fat on the world's misfortunes? That was when he began to suspect a connection between his inner ragings and Europe 's war, and feared for his sanity. He fled from the battlefield into the numbing grind of the
Tabulae Rudolphinae.
There, among the orderly marching columns of Tycho Brahe's lifework, he could hide. But not for long. Soon that manoeuvre was exhausted. Then he embarked on the first of his strange frantic wanderings. On the road he felt easier, the clash of battle within him stilled for a while by the pains and frustration of travel. It seemed to be what the demon wanted.
He used as excuse the moneys owed him by the crown. The printing of the
Tables
would be a costly business. He set out for Vienna and Ferdinand's court. After four months of haggling there he won a grudging part settlement of 6,000 florins. The Treasury, however, cleverer and more careful than the Emperor, immediately transferred responsibility for the payment to the three towns of Nuremberg, Kempten and Memmingen. Once more Kepler set off, seeming to hear Vienna break out in general hilarity behind him. By the end of winter he had collected from the tight-fisted trinity of towns 2,000 florins. It would buy the paper for the
Tables.
The effort had exhausted him, and he turned wearily towards home.
When he got to Linz he found the city transformed into a military camp. The Bavarian garrison sent in by the Emperor was billeted everywhere. At Plank the printer's a squad of soldiers was sprawled at feed among the presses, their stink overlaying the familiar smells of ink and machine oil. All work had stopped. They watched him incuriously as he danced before them in helpless rage. He might have dropped into their midst from another planet. They were for the most part the sons of poor farmers. When the printing got under way at last they began to display a childlike interest in the work: few of them had ever seen a machine working before. They would gather about Plank's men in silent groups, staring and softly breathing like cattle at a stile. The sudden white flourish of a pulled proof never failed to call forth a collective sigh of surprise and pleasure. Later on, when the amazing fact had soaked into their understanding that Kepler was the sole cause of all this mighty effort, they turned their awed attention on to him. They would jostle to get near him at the benches or the readers' desk, trying to sift out of his talk of fonts and colophons and faces some clue to the secret of his wizardry. And occasionally they would pluck up courage enough to offer him a mug ofbeer or a twist of tobacco, grinning furiously, at their boots and sweating. He grew accustomed to their presence, and ceased to heed them, except that now and then something spoke to him, at once faint and insistent, out of this warm noisome mass of life pressing at his back. Then he would fly into a rage again, and yell into their stunned faces, and stamp out of the shop, waving his arms.
In the spring the Lutheran peasantry revolted, sick of being harried, of being hungry, sick most of all of their arrogant Emperor. They swept across Upper Austria, delirious with success, unable to believe their own strength. By early summer they were at the walls of Linz. The siege lasted for two months. The city had been ill-prepared, and was quickly reduced to horse meat and nettle soup. Kepler's house was on the wall, and from his workroom he could look down across the moats and the suburbs where the fiercest fighting took place. How small the protagonists looked from up here, and yet how vivid their blood and their spilled guts. The smell of death bathed him about as he worked. A detachment of troops was quartered in his house. Some among them he recognised from the printing house. He had thought his children would be terrified, but they seemed to regard it all as a glorious game. One morning, in the midst of a bitter skirmish, they came to tell him that there was a dead soldier in his bed.
"Dead, you say? No, no, he is wounded merely; your mama put him there to rest. "
Cordula shook her head. Such a serious little girl! "He is
dead, "
she said firmly. "There is a fly in his mouth. "
Towards the end of June the peasant forces breached the wall one night and set fire to a section of streets before being repulsed. Plank's shop was destroyed, and with it all the sheets of the
Tables
so far printed. Kepler decided it was time to move. By October, the siege long since lifted and the peasants crushed, he had packed up everything that he owned and was on his way to Ulm, excommunicate and penniless, never to return.
In Ulm for a while he was almost happy. He had left Susanna and the children in Regensburg, and, alone once more after so many years, he felt as if time had magically fallen away and he was back in Graz, or Tübingen even, when life had not properly begun, and the future was limitless. The city physician Gregor Horst, an acquaintance from his Prague days, leased him a little house in Raben Alley. He found a printer one Jonas Saur. The work went well at first. He still imagined that the
Tables
would make his fortune. He spent his days in the printing house. On Saturday nights he and Gregor Horst would get quietly drunk together and argue astronomy and politics into the small hours.
But he could not be at rest for long. The old torment was rising once more in his heart. Saur the printer lived up to his name, and there were quarrels. Yet again Kepler turned his hopes toward Tübingen and Michael Mästlin; could Gruppenbach, who had printed the
Mysterium,
finish off for him the
Tables?
He wrote to Mästlin, and getting no reply he set out for Tübingen on foot. But it was February, the weather was bad, and after two days he found himself halted at a crossroads in the midst of turnip fields, exhausted and in despair, but not so far gone that he could not see, with wry amusement, how all his life was summed up in this picture of himself, a little man, wet and weary, dithering at a fork in the road. He turned back. The town council at Esslingen presented him with a horse, got from the town's home for the infirm. The beast bore him bravely enough to Ulm and then died under him. Again he saw the aptness of it, this triumphal entry, on a broken-down jade, into a city that hardly knew him. He made his peace with Jonas Saur, and at last, after twenty years, the
Tables
were hauled to completion.
Two kinsmen of Tycho Brahe called on him one day at his lodgings in Raben Alley, Holger Rosenkrands the statesman's son and the Norwegian Axel Gyldenstjern. They were on their way to England. Kepler considered. Wotton, King James's ambassador to Prague, had urged him once to come to England. Rosenkrands and Gyldenstjern would be happy to take him with them. Something held him back. How could he leave his homelands, however bad the convulsions of war? There was nothing for him but to go to Prague. He had the
Tables
at least to offer the Emperor. It was not likely it would be enough. His time was past. Even Rudolph in his latter days had grown bored with his mathematician. But he must go somewhere, do something, and so he took himself aboard a barge bound for the capital, where, unknown to both of them, Wallenstein awaited him.
* * *
Now, baking his chilblains at Hillebrand Billig's fire, he brooded on his time in Sagan. It had been at least a refuge, where for a while he had held still, the restlessness of his heart feeding vicariously on his new master's doings. Wallenstein's world was all noise and event, a ceaseless coming and going to the accompaniment of distant cannonades and hoofbeats at midnight: as if he too were in flight from an inexorable demon of his own. Yet Kepler had never known a man who so fitted the shape and size of his allotted space. What emptiness could there be in
him,
that a stalking devil would seek for a home?
Billig was laboriously doing the tavern accounts at the kitchen table, licking his pencil and sighing. Frau Billig sat near him, darning her children's stockings. They might have been done by Dürer. A draught from the window shook the candlelight. There was the sound of the wind and the rain, the muffled roars of the Saturday night revellers in the tavern, the crackling of the fire, the old dog's snores, but beneath all a deep silence reigned, secret and inviolable, perhaps the silence of the earth itself. Why, dear Christ, did I leave home to come on this mad venture?
At first he had been wary of Wallenstein. He feared being bought for a plaything, for the general's obsession with astrology was famous. Kepler was too old and too tired to take up again that game of guesswork and dissimulation. For months he had held back, worrying at the terms Wallenstein was offering him, wanting to know what would be required of him in return. Conversation, said Wallenstein, smiling, your company, the benefit of your learning. The Emperor, with ill-concealed enthusiasm, urged him to accept the offered post, and took the opportunity to transfer on to Wallenstein the crown's considerable debt to its mathematician. Wallenstein made no protest; his blandness caused Kepler's heart to sink. Also the astronomer would be granted an annual stipend o: 1,000 florins from the Sagan coffers, a house at Gitschin where the general had his palace, and the use of a printing press with sufficient paper for whatever books he might wish to publish, all this without condition or hindrance. Kepler dared to hope. Could it be, at last, could it be..?
It could not. Wallenstein indeed believed he had purchased a tame astrologer. In time, after many clashes, they had come to an arrangement whereby Kepler supplied the data out of which more willing wizards would work up the horoscopes anc calendars. For the rest he was free to do as he wished. He saw no sign of the imperial debt being settled, nor of the printing works and the paper that had been promised. Things might have been worse. There was the house at least, and now and then he was even paid a little of his salary on account. If he was not happy, neither was he in despair. Hitzler's word came back to him: tepid. Sagan was a barbaric place, its people peculiar and cold, their dialect incomprehensible. There were few diversions. Once he travelled down to Tübingen and spent a gloriously tipsy month with old Mästlin, deaf and doddering now but merry withal. And one day Susanna came to him, with a look of mingled amusement and surprise, to announce that she was pregnant.
