The Dancing Plague of 1518

Eric Marquette

It was mid-July, 1518, in Strasbourg—an otherwise ordinary summer afternoon in the Holy Roman Empire. But, as the story goes, the unthinkable began with just one woman. Frau Troffea. Without warning, she stepped into the street and started to dance. Not gracefully, mind you, but fervently, frantically, as if gripped by some unseen force. And she didn’t stop. For hours, she spun and swayed, her feet pounding against the cobblestones, showing no sign of fatigue, no awareness of her surroundings.

Onlookers thought it odd, but curiosity gave way to concern as the hours turned into days. Still, Frau Troffea’s relentless motion endured. And then, something even stranger happened. Others joined her. First a few, then dozens. By the end of that fateful week, more than thirty people had succumbed to this inexplicable urge to dance. By the end of the month, the number had grown to nearly four hundred. Men, women, young and old—nobody seemed immune to the compulsion.

And here’s the chilling part—the dancing wasn’t joyous or celebratory. Historical accounts describe the participants as being trapped in their bodies, their arms flailing, their faces expressionless, their movements erratic. Some screamed for help as they danced, others appeared driven to exhaustion. Many collapsed. And tragically, some would never rise again. Deaths from strokes, heart attacks, and sheer physical strain were reported.

This wasn’t the first time Europe had witnessed such bizarre outbreaks. In fact, scholars identified it as part of a phenomenon known as choreomania—a “dancing madness” cited in medieval records that spanned centuries. These events, they say, were linked to periods of great distress—times when famine, disease, and spiritual desperation gripped communities. It seems Strasbourg, in 1518, was the perfect storm of all three.

By the time the number of afflicted dancers reached hundreds, the entire city of Strasbourg was in an uproar. The council, scrambling for answers, turned to local physicians for guidance. Their diagnosis? “Hot blood.” A vague and somewhat baffling explanation, but it was enough for the city authorities to implement what could only be described as an unorthodox solution. They decided to let the dancers dance.

And so, musicians were recruited, stages were constructed, and the dancers were given space—quite literally—to spin themselves into oblivion. It might sound absurd now, but at the time, the logic was simple: let them exhaust the affliction out of their systems. But this cure proved to be worse than the disease. The music, intended to drive the dancers to collapse, only seemed to draw in more participants. The mania spread like wildfire, and the city square transformed into a chaotic theater of unstoppable motion.

It wasn’t long before desperation pushed officials to consider another path—one rooted in medieval faith and superstition. The afflicted were sent to the shrine of Saint Vitus, a revered figure believed to hold sway over maladies of the mind and body. Pilgrims wore red shoes marked with crosses and sprinkled with holy water, and as part of the ritual, they marched to the chapel. There, incense burned, prayers were chanted, and the hope of divine intervention hung in the air.

This wasn’t the first time such fervent rituals were prescribed for dancing plagues. Across medieval Europe, dancing outbreaks were often attributed to possession, divine punishment, or curses. In Italy, there were cases of “Tarantism,” where people believed a spider bite could force them into uncontrollable dancing—dancing, they believed, would purge the venom. These interpretations mirrored the ways societies tried to rationalize what they couldn’t explain. Dance, after all, wasn’t merely celebratory in those times—it bordered on the spiritual, even the supernatural. And here in Strasbourg, it blurred those lines even further, manifesting as both salvation and affliction.

Now, what exactly could have driven hundreds of people in Strasbourg to dance to their deaths? Theories abound, each more intriguing—or more chilling—than the last. Historical scholars point to mass hysteria as a likely culprit. Life in the 16th century wasn’t easy. Famine, disease, and staggering poverty left communities teetering on the edge of despair. Imagine the collective stress, layering like sediment, until it finally—well—broke free. In this case, through dance. It’s not just a peculiar idea. The concept of mass psychogenic illness, where psychological trauma takes physical form, is well-documented even in modern times.

But let’s not stop there. Another widely discussed hypothesis is ergot poisoning. Ergot, a mold that grows on damp rye, can produce a chemical similar to LSD. Folks back then were unknowingly consuming this contaminated grain, which—potentially—explains the convulsions, hallucinations, and erratic behaviors described in accounts. Sounds plausible, doesn’t it? But here’s the counterpoint: Could people really dance for weeks on end under its influence? And, you know, why weren’t entire communities affected equally? The puzzle deepens.

Then, there’s Paracelsus, the bold 16th-century physician, who waded into the debate with his own take. He claimed the dancing was rooted in, well, shall we say, "worldly indulgences." He argued that some may have been masking social improprieties under a guise of illness. You can see how interpretations took on the flavor of their time. Religious leaders viewed this as a force of possession—or a punishment from on high. Physicians toyed with explanations like “hot blood,” while others whispered about curses or hexes. The fact that not one cause fits all tells us how slippery this story is.

And yet, the significance of the Dancing Plague stretches far beyond speculation. It’s left its mark—lingering in our art, our research, even our pop culture. From Florence and the Machine’s haunting lyrics to tales woven by novelists and playwrights, the 1518 dancing frenzy has transcended time. It’s a reminder—for centuries now—of the fragile line between the mind and the body, between chaos and control. Its echoes remain unsettling, not just because it’s inexplicable, but because it reflects something deeply human: our need to question, to explain the unexplainable. And maybe, just maybe, to embrace the mystery itself.
