It started on a hot July day in Strasbourg. A single woman stepped out into the street and began to dance. She danced alone, with no music, her movements wild and uncontrolled. Within a week, dozens more had joined her.
By August, the number had swelled to around 400 people. They danced in the streets, day and night, their bodies contorting and their faces filled with exhaustion. They couldn't stop, even as their feet bled and their bodies gave out. This was the beginning of the infamous Dancing Plague of 1518.
A City Gripped by Uncontrollable Movement
The city officials were baffled. They had never seen anything like it. The dancers seemed possessed, their energy seemingly endless yet destructive. Doctors at the time could offer no explanation. They believed the dancers were suffering from a condition called "hot blood."
To combat this supposed ailment, the authorities decided on a strange course of action. They encouraged the dancing. They believed that if the afflicted people danced the fever out of their systems, they would eventually recover. They even set up a stage and hired musicians, hoping the dancing would be contained and would run its course.
The Dancing Continues, and Worsens
This approach, however, did not help. The music and the stage only seemed to fuel the frenzy. The dancers kept going, their movements becoming more desperate. Some collapsed from sheer exhaustion. Others suffered heart attacks or strokes. The streets of Strasbourg became a scene of public madness and suffering.
It's hard to imagine the fear and confusion that must have gripped the city. Families watched helplessly as their loved ones danced themselves to the brink of death. The air must have been thick with the sounds of frantic music and the gasps of the exhausted dancers.
Theories
Behind the Madness
Over the centuries, many theories have been proposed to explain the dancing plague. One of the most popular is that the dancers consumed ergot fungus. This fungus, which grows on rye, can cause hallucinations and uncontrollable muscle spasms, similar to what was described.
