Abstract
It is 1618 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, Katharina Kepler, an illiterate widow, is accused of being a witch. Katharina is known for her herbal remedies and the success of her children. Her eldest, Johannes, is the Imperial Mathematician and the renowned author of the laws of planetary motion. It’s enough to make anyone envious, and Katharina has done herself no favours by going out and about and being in everyone’s business.
