St. John's Dance

Dancing mania was a phenomenon that occurred primarily in mainland Europe from the 14th century through to the 17th century, in which groups of people would dance through the streets of towns or cities, sometimes foaming at the mouth or speaking in tongues, until they collapsed from exhaustion. The first major outbreak of the mania was in Aachen, Germany, on June 24th, 1374. The dancers went through the streets screaming of wild visions, and even continued to writhe and twist after they collapsed from exhaustion. The dancing quickly caught on, and spread rapidly throughout France and the Low Countries.
