Dancing plagues

In 1518 an enigmatic psychiatric condition broke out around Strasbourg in France (Blom, 2010; Hecker, 1837; Tuke, 1892). The dancing plague commenced with one Frau Troffea, who began a fervent dancing vigil that lasted between four and six days. Within a week 34 other citizens of the town had joined her in dancing, and by the end of the month the numbers had swelled to over 400. Medical authorities thought that the only cure would come with further dancing, but this resulted in dozens of deaths from heart attacks, strokes and sheer exhaustion. Several theories have been put forward to explain this phenomenon, ranging from the effects of ergotism (poisoning from an hallucinogenic fungus that contaminates bread; Blom, 2010; Golden, 2006; Melechi, 2003; Tuke, 1892) to mass psychogenic illness (a form of mass hysteria usually preceded by intolerable levels of psychological distress) (O’Neill, n.d.; Waller, 2009). At least seven other outbreaks of dancing mania occurred in medieval Europe, all with no rational explanation at the time (Blom, 2010; Hecker, 1837; Viegas, 2008).
