The Black Death, and the Dancing Mania

The Black Death killed an estimated third of Europe in the 14th century. Justus Hecker, an early 19th-century German physician and medical historian, writes with clinical precision about this catastrophe, drawing on contemporary accounts from physicians like Guy de Chauliac and witnesses like Boccaccio. But this book offers something stranger: an investigation into the dancing mania, the inexplicable phenomenon where thousands of people, sometimes entire towns, would begin dancing and not stop until they collapsed from exhaustion, injury, or death. These episodes swept through Europe for centuries, leaving historians and physicians baffled. Hecker approaches both phenomena as windows into the medieval mind: how communities responded to existential terror, how fear reshaped behavior and belief, how disease and madness became entangled in the European imagination. His account is both medical documentation and cultural history, a record of how humanity confronts its own fragility when the body rebels against reason.
