History's Mysteries: The Dancing Plague of 1518 In the summer of 1518, a woman stepped into the streets of Strasbourg and began to dance - compulsively, and without rest. Within days, dozens had joined her. Within weeks, the number rose into the hundreds. Some collapsed from exhaustion. Others reportedly danced to their deaths. What caused this bizarre and haunting episode, now known as the Dancing Plague of 1518? Was it a natural illness, or something deeper? This book explores one of the strangest events in European history through the lens of contemporary chronicles, city council records, religious writings, and modern scientific research. It traces the steps of Frau Troffea, the first dancer, and follows the spread of the phenomenon through Strasbourg's streets and beyond. We look at the official responses, contemporary measures, spiritual remedies, and competing theories from medicine, psychology, and sociology. This book offers a deeply researched, compelling account of one of Medieval Europe's most haunting and perplexing mysteries.
