In The Astronomer and the Witch, Ulinka Rublack pieces together the tale of this extraordinary episode in Kepler's life, one that takes us to the heart of his changing world.

Johannes Kepler (1571-1630) was one of the most admired astronomers who ever lived and a key figure in the scientific revolution. A defender of Copernicus ́ s sun-centred universe, he famously discovered that planets move in ellipses, and defined the three laws of planetary motion. Perhaps less well known is that in 1615, when Kepler was at the height of his career, his widowed mother Katharina was accused of witchcraft. The proceedings led to a criminal trial that lasted six years, with Kepler conducting his mother's defence. In The Astronomer and the Witch, Ulinka Rublack pieces together the tale of this extraordinary episode in Kepler's life, one which takes us to the heart of his changing world. First and foremost an intense family drama, the story brings to life the world of a small Lutheran community in the centre of Europe at a time of deep religious and political turmoil - a century after the Reformation, and on the threshold of the Thirty Years' War. Kepler's defence of his mother also offers us a fascinating glimpse into the great astronomer's world view, on the cusp between Reformation and scientific revolution. While advancing rational explanations for the phenomena which his mother's accusers attributed to witchcraft, Kepler nevertheless did not call into question the existence of magic and witches. On the contrary, he clearly believed in them. And, as the story unfolds, it appears that there were moments when even Katharina's children struggled to understand what their mother had done...

Drawing on real historical documents but infused with the intensity of imagination, sly humor, and intellectual fire for which award-winning author Rivka Galchen’s writing is known, Everyone Knows Your Mother Is a Witch is a tale for our time—the story of how a community becomes implicated in collective aggression and hysterical fear. The year is 1619, in the German duchy of Württemberg. Plague is spreading. The Thirty Years War has begun, and fear and suspicion are in the air throughout the Holy Roman Empire. In the small town of Leonberg, Katherina Kepler is accused of being a witch. An illiterate widow, Katherina is known by her neighbors for her herbal remedies and the success of her children, including her eldest, Johannes, who is the Imperial Mathematician and renowned author of the laws of planetary motion. It’s enough to make anyone jealous, and Katherina has done herself no favors by being out and about and in everyone’s business. So when the deranged and insipid Ursula Reinbold (or as Katherina calls her, the Werewolf) accuses Katherina of offering her a bitter, witchy drink that has made her ill, Katherina is in trouble. Her scientist son must turn his attention from the music of the spheres to the job of defending his mother. Facing the threat of financial ruin, torture, and even execution, Katherina tells her side of the story to her friend and next-door neighbor Simon, a reclusive widower imperiled by his own secrets. Provocative and entertaining, Galchen’s bold new novel touchingly illuminates a society, and a family, undone by superstition, the state, and the mortal convulsions of history.

Heavenly Intrigue is the fascinating, true account of the seventeenth-century collaboration between Johannes Kepler and Tycho Brahe that revolutionized our understanding of the universe–and ended in murder.One of history’s greatest geniuses, Kepler laid the foundations of modern physics with his revolutionary laws of planetary motion. But his beautiful mind was beset by demons. Born into poverty and abuse, half-blinded by smallpox, he festered with rage, resentment, and a longing for worldly fame. Brahe, his mentor, was a flamboyant aristocrat who had spent forty years mapping the heavens with unprecedented accuracy–but he refused to share his data with Kepler. With Brahe’s untimely death in Prague in 1601, rumors flew across Europe that he had been murdered. But it took twentieth-century forensics to uncover the poison in his remains, and the detective work of Joshua and Anne-Lee Gilder to identify the prime suspect–the ambitious, envy-ridden Kepler himself. A fast-paced, true-life account that reads like a thriller, Heavenly Intrigue is a remarkable feat of historical re-creation.

Masterpiece of historical insight and scientific accuracy and the definitive work on Greek astronomy and the Copernican Revolution. Includes surveys of European and Islamic cosmologies of the Middle Ages and the Renaissance.
