@kennethkolbrak: In July 1518, a woman stepped into a street in Strasbourg and began to dance. She couldn't stop. Within a week, 30 more had joined her, and by August as many as 400 were dancing. The doctors' cure was more dancing. 500 years later, historians still argue about what happened: ergot poisoning, or a mass psychogenic illness brought on by famine, disease and fear of St. Vitus's curse? #History #dancingplague #mystery #historyfacts
