Baiting his father-in-law was a way of avoiding his bride. They had hardly spoken, had hardly met, during the long months of negotiation, and today when by chance they found themselves confronting each other they were paralysed by embarrassment. She looked, he gloomily observed, radiant, that seemed the appropriate word. She was pretty, in a vacant way. She twittered. Yet when amid a chiming of uplifted glasses he pressed his palms awkwardly to her damp trembling back and kissed her for the benefit of the company, he suddenly found himself holding something unexpectedly vivid and exotic, a creature of another species, and, catching her warm spicy smell, he was excited. He began to swill in earnest then, and was soon deliriously drunk. But even that was not enough to stifle his fright.

Yet in the weeks and months that followed he was almost happy. In May the first copies of the Mysterium arrived from Tübingen. The slim volume pleased him enormously. His pleasure was a little tainted however by a small obscure shame, as if he had committed an indiscretion the awfulness of which had not yet been noticed by an inattentive public. This was the first blush of that patronising attitude to the book, which in later years was to make it seem the production of a heedless but inspired child that he but vaguely remembered having been. He distributed copies among selected astronomers and scholars, and a few influential Styrians that he knew, all of whom, to his indignation and dismay, proved less than deafening in their shouts of surprise and praise.

The number of volumes he had contracted to buy under the printer's terms cost him thirty-three florins. Before his marriage he could not have afforded it, but now, it seemed, he was rich. Besides the sum Jobst Müller had settled on him, his salary had been increased by fifty florins annually. That, however, was a trifle compared with his wife's fortune. He was never to succeed in her lifetime in finding out how much exactly she had inherited, but it was greater even than the most eager of matchmakers had imagined. Regina had a sum of ten thousand from her late father, Wolf Lorenz the cabinetmaker, Barbara's first casualty. If the child had that much, how much more must her mother have got? Kepler rubbed his hands, elated, and shocked at himself too.

There was another form of wealth, more palpable than cash and as quickly squandered, which was a kind of burgeoning fortune of the senses. Barbara, for all her twittering silliness, was flesh, a corporeal world, wherein he touched and found startlingly real, something that was wholly other and yet recognisable. He flared under her light, her smell, the faintly salt taste of her skin. It took time. Their first encounters were a failure. On the wedding night, in the vast four-poster in the bedroom overlooking Stempfergasse, they collided in the dark with a crunch. He felt as if he were grappling with a heavy hot corpse. She fell all over him, panting, got an elbow somehow into his chest and knocked the wind out of him, while the bed creaked and groaned like the ghost voice of its former tenant, poor dead Marx Müller, lamenting. When the union was consummated at last, she turned away and immediately fell asleep, her snores a raucous and monotonously repeated protest. It was not until many months later, when the summer was over and cold winds were blowing down from the Alps, that they at last found each other, briefly.

He remembered the evening. It was September, the trees were already beginning to turn. He had stood up from a good day's work and walked into their bedroom. Barbara was bathing in a tub before a fire of sea-coals, dreamily soaping an extended pink leg. He turned away hastily, but she looked up and smiled at him, dazed with heat. A narrow shaft of late sunlight, worn to the colour of old brass, lay aslant the bed. Ouf! she said, and rose in a cascade of suds and slithering water. It was the first time he had seen her entirely naked. Her head sat oddly upon this unfamiliar bare body. Aglow and faintly steaming she displayed herself, big-bummed, her stout legs braced as if to leap, a strongman's shovel-shaped beard glistening in her lap. Her breasts stared, wall-eyed and startled, the dark tips pursed. He advanced on her, his clothes falling away like flakes of shell. She rose on tiptoe to peer past him down into the street, biting her lip and laughing softly. "Someone will see us, Johannes. " Her shoulder-blades left a damp print of wings upon the sheet. The brazen sword of sunlight smote them.

It was at once too much and not enough. They had surrendered their most intimate textures to a mere conspiracy of the flesh. It took him a long time to understand it; Barbara never did. They had so little in common. She might have tried to understand something of his work, but it was beyond her, for which she hated it. He could have tried also, could have asked her about the past, about Wolf Lorenz the wealthy tradesman, about the rumours that Marx Müller the district paymaster had embezzled state funds, but from the start these were a forbidden topic, jealously guarded by the sentinels of the dead. And so, two intimate strangers lashed together by bonds not of their making, they began to hate each other, as if it were the most natural thing in the world. Kepler turned, hesitantly, shyly, to Regina, offering her all the surplus left over from his marriage, for she represented, frozen in prototype, that very stage of knowing and regard which he had managed to miss in her mother. And Barbara, seeing everything and understanding nothing, grew fitful and began to complain, and sometimes beat the child. She demanded more and more of Kepler's time, engaged him in frantic incoherent conversations, was subject to sudden storms of weeping. One night he found her crouched in the kitchen, gorging herself on pickled fish. The following morning she fainted in his arms, nearly knocking him down. She was pregnant.

She fulfilled her term as she did everything, lavishly, with many alarms and copious tears. She became eerily beautiful, for all her bulk. It was as if she had been designed for just this state, ancient and elemental; with that great belly, those pendant breasts, she achieved a kind of ideal harmony. Kepler began to avoid her: she frightened him now more than ever. He spent the days locked in his study, tinkering with work, writing letters, going over yet again his hopelessly unbalanced accounts, lifting his head now and then to listen for the heavy tread of the goddess.

She went early into labour, blundered into it one morning with shrill cries. The waves of her pain crashed through the house, wave upon wave. Dr Oberdorfer arrived, puffing and mumbling, and heaved himself up the stairs on his black stick like a weary oarsman plying a foundering craft. It struck Kepler that the man was embarrassed, as if he had caught indulging in some base frolic this couple whose troubled destinies he had helped to entangle. Her labour lasted for two days. The rain of February fell, clouding the world without, so that there was only this house throbbing around its core of pain. Kepler trotted up and down in a fever of excitement and dismay, wringing his hands. The child was born at noon, a boy. A great blossom of heedless happiness opened up in Kepler's heart. He held the softly pulsing mite in his hands and understood that he was multiplied. "We shall call him Heinrich," he said, "after my brother-but you will be a better, a finer Heinrich, won't you, yes." Barbara, pale in her bloodied bed, stared at him emptily through a film of pain.

He drew up a horoscope. It promised all possible good, after a few adjustments. The child would be nimble and bright, apt in mathematical and mechanical skills, imaginative, diligent, charming, O, charming! For sixty days Kepler's happiness endured, then the house was pierced again by screams, miniature echoes of Barbara's lusty howls, and Oberdorfer again sculled himself up the stairs and Kepler snatched the infant in his arms and commanded it not, not to die! He turned on Barbara, she had known, all that pain had told her all was wrong, yet she had said nothing, not a word to warn him, spiteful bitch! The doctor clicked his tongue, for shame, sir, for shame. Kepler rounded on him. And you… you…! In tears, his vision splintering, he turned away, clasping the creature to him, and felt it twitch, and cough, and suddenly, as if starting in amazement, die: his son. The damp hot head lolled in his hand. What pitiless player had tossed him this tender ball of woe? He was to know other losses, but never again quite like this, like a part of himself crawling blind and mewling into death.
