The following podcast may not be
for all listeners. 

2
00:00:03,400 --> 00:00:11,680
Listener discretion is advised. 
Some horrors cannot be explained

3
00:00:12,160 --> 00:00:15,840
and some mysteries refuse to be 
solved. 

4
00:00:16,720 --> 00:00:21,280
Some historical events are so 
bizarre that they mock our 

5
00:00:21,280 --> 00:00:27,120
understanding of reality. 
In the summer of 1518, a woman 

6
00:00:27,120 --> 00:00:32,240
named Frau Troffe began to dance
in the street in Strasbourg. 

7
00:00:32,520 --> 00:00:38,040
She didn't stop for days, No 
music played, her feet bled, and

8
00:00:38,040 --> 00:00:41,640
she still danced. 
Within a week, Moore joined her 

9
00:00:41,640 --> 00:00:46,320
frenzied ballet, and by the 
month's end 400 people were 

10
00:00:46,320 --> 00:00:49,280
dancing themselves to death in 
the streets. 

11
00:00:50,040 --> 00:00:54,400
Doctors of the time were 
baffled, and modern scientists 

12
00:00:54,720 --> 00:00:58,440
remained perplexed. 
What force could possess 

13
00:00:58,440 --> 00:01:01,560
hundreds of people to dance 
until they died? 

14
00:01:05,519 --> 00:01:08,800
Welcome to unexplained realms. 
I'm your host, Anne. 

15
00:01:09,240 --> 00:01:13,520
In this episode, we are stepping
into one of history's darkest 

16
00:01:13,720 --> 00:01:18,680
and most peculiar mysteries, the
Dancing Plague of 1518. 

17
00:01:28,160 --> 00:01:32,800
In the shadows of eastern France
lies Strasbourg, where ancient 

18
00:01:32,800 --> 00:01:36,320
cobblestones whisper secrets of 
madness and faith. 

19
00:01:37,320 --> 00:01:40,280
While tourists flock to 
photograph the European 

20
00:01:40,280 --> 00:01:44,360
Parliament and gawk at the 
Gothic Spires of Notre Dame, 

21
00:01:45,000 --> 00:01:48,800
they remain blissfully unaware 
of the city's darker pulse. 

22
00:01:49,440 --> 00:01:52,880
This rhythm echoes through 
centuries of blood soaked 

23
00:01:52,880 --> 00:01:56,280
history. 
The Rhine River flows past the 

24
00:01:56,280 --> 00:02:01,520
city's edges, its waters holding
memories of countless souls who 

25
00:02:01,520 --> 00:02:05,800
succumbed to a psychological 
horror that once gripped these 

26
00:02:05,800 --> 00:02:09,520
streets. 
Forget the tales of the Devil's 

27
00:02:09,520 --> 00:02:13,320
Wind or even the Huns trop 
Christmas demon. 

28
00:02:14,280 --> 00:02:21,440
The true nightmare of Strasbourg
emerged in 1518, when dozens of 

29
00:02:21,440 --> 00:02:25,000
citizens began to dance 
themselves to death in the 

30
00:02:25,000 --> 00:02:32,560
streets, their bodies twisting 
and convulsing in an unstoppable

31
00:02:32,560 --> 00:02:37,080
frenzy until their feet bled and
their hearts gave out. 

32
00:02:38,640 --> 00:02:42,920
Some say that on quiet nights, 
when the moon hangs low over the

33
00:02:42,920 --> 00:02:48,320
Alisation rooftops, you can 
still hear the phantom echoes of

34
00:02:48,320 --> 00:02:55,680
their frenzied footsteps. 
It all began in 1518 when a 

35
00:02:55,680 --> 00:02:59,720
woman named Frau Troffe was 
compelled to dance. 

36
00:03:01,120 --> 00:03:03,760
She stepped into the street and 
began dancing. 

37
00:03:04,400 --> 00:03:08,840
She seemed unstoppable, dancing 
until she collapsed from 

38
00:03:08,840 --> 00:03:13,680
exhaustion. 
Then, once she had rested, she 

39
00:03:13,680 --> 00:03:18,320
started dancing again, in a 
frenzied yet compulsive way. 

40
00:03:20,200 --> 00:03:25,080
Within days of her first manic 
steps, her solitary dance became

41
00:03:25,080 --> 00:03:29,600
a grotesque Symphony, like a 
disease spreading through the 

42
00:03:29,600 --> 00:03:33,640
medieval streets. 
The compulsion infected others, 

43
00:03:34,000 --> 00:03:40,200
first dozens, then hundreds. 
The cobblestones of Strasbourg 

44
00:03:40,200 --> 00:03:43,880
became a stage for humanity's 
most disturbing ballet. 

45
00:03:44,480 --> 00:03:47,680
These weren't the graceful 
movements of celebration. 

46
00:03:48,160 --> 00:03:52,400
These dancers moved as if 
possessed, their limbs jerking 

47
00:03:52,400 --> 00:04:00,880
and twisting unnaturally, their 
faces contorted in agony even as

48
00:04:00,880 --> 00:04:05,720
their feet refused to stop. 
Blood seeped through their 

49
00:04:05,720 --> 00:04:09,560
shoes, leaving Crimson trails 
across the stones. 

50
00:04:10,840 --> 00:04:15,160
Some danced until their ribs 
cracked, their bodies drenched 

51
00:04:15,160 --> 00:04:20,320
in sweat, mouths foaming, eyes 
rolling back in their heads. 

52
00:04:22,960 --> 00:04:27,160
In their infinite wisdom, the 
city's authorities decided that 

53
00:04:27,160 --> 00:04:34,000
the afflicted must dance it out.
They constructed wooden stages 

54
00:04:34,000 --> 00:04:39,240
in Guild halls and hired 
musicians, as if adding melody 

55
00:04:39,240 --> 00:04:41,760
to madness would somehow cure 
it. 

56
00:04:43,360 --> 00:04:47,000
Till this point, they had all 
danced in silence. 

57
00:04:48,920 --> 00:04:52,560
City authorities thought 
specific locations would control

58
00:04:52,560 --> 00:04:56,960
the crowd. 
Instead, they created a theater 

59
00:04:56,960 --> 00:05:02,000
of horrors where people danced 
themselves to death while others

60
00:05:02,000 --> 00:05:06,960
watched, wondering if they would
be next to contract this dancing

61
00:05:06,960 --> 00:05:11,160
plague. 
Through it all, Fro Trofe kept 

62
00:05:11,160 --> 00:05:15,240
dancing, her initial steps 
having unleashed something 

63
00:05:15,240 --> 00:05:18,120
science still struggles to 
explain. 

64
00:05:19,920 --> 00:05:24,440
Was it mass hysteria, a fungal 
infection in the grain, or 

65
00:05:24,440 --> 00:05:28,360
something darker, an ancient 
curse awakened in the heart of 

66
00:05:28,360 --> 00:05:34,360
Elsais? 
In the end, up to 15 people died

67
00:05:34,360 --> 00:05:38,800
each day, their bodies finally 
finding the peace their minds 

68
00:05:38,800 --> 00:05:43,680
wouldn't give them. 
All that's left of this bizarre 

69
00:05:43,680 --> 00:05:47,040
tale is what might have 
triggered these bizarre, 

70
00:05:47,040 --> 00:05:51,840
frenzied motions. 
Deep in the dark heart of this 

71
00:05:51,840 --> 00:05:57,960
mystery lies a possible 
microscopic answer ergot, a 

72
00:05:57,960 --> 00:06:03,360
toxic fungus that transforms 
grains into vessels of madness. 

73
00:06:05,280 --> 00:06:09,960
In medieval Strasburg's grain 
stores, these infected kernels 

74
00:06:09,960 --> 00:06:15,360
would have lurked like tiny time
bombs, their purple black spores

75
00:06:15,360 --> 00:06:20,000
nestled among the healthy seeds,
waiting to be ground into the 

76
00:06:20,000 --> 00:06:22,880
daily bread that sustained the 
city. 

77
00:06:24,280 --> 00:06:29,560
When consumed, ergot's potential
cocktail of alkaloids attacks 

78
00:06:29,560 --> 00:06:35,240
the central nervous system with 
savage efficiency, the same 

79
00:06:35,240 --> 00:06:39,200
compounds that would later 
inspire the creation of the drug

80
00:06:39,400 --> 00:06:45,400
LSD that twists reality into 
nightmarish shapes. 

81
00:06:47,480 --> 00:06:51,640
Victims experience violent 
muscle spasms and convulsions 

82
00:06:51,640 --> 00:06:56,720
that, to horrified onlookers, 
might have appeared as frenzied 

83
00:06:56,720 --> 00:06:59,960
dancing. 
The toxin constricts blood 

84
00:06:59,960 --> 00:07:03,560
vessels, sending burning 
sensations through the limbs. 

85
00:07:04,080 --> 00:07:08,360
A feeling medieval sufferer is 
described as being tortured by 

86
00:07:08,360 --> 00:07:13,080
invisible flames. 
And Ergot's horror doesn't stop 

87
00:07:13,080 --> 00:07:16,880
at the physical symptoms. 
The fungus reaches into your 

88
00:07:16,880 --> 00:07:21,760
mind itself, spawning 
hallucinations and psychotic 

89
00:07:21,760 --> 00:07:25,400
episodes. 
Imagine the terror, your muscles

90
00:07:25,400 --> 00:07:29,680
betraying you, your mind 
fracturing while vision stands 

91
00:07:29,680 --> 00:07:31,680
at the edges of your 
consciousness. 

92
00:07:33,280 --> 00:07:36,520
The dancers of Strasbourg might 
have been trapped in their 

93
00:07:36,520 --> 00:07:42,320
personal Hells, their bodies 
wracked by involuntary movements

94
00:07:42,320 --> 00:07:47,200
while their poisoned minds spun 
through kaleidoscopic torment. 

95
00:07:48,400 --> 00:07:52,360
This theory gains darker weight 
when we consider Stromberg's 

96
00:07:52,360 --> 00:07:56,880
climate in 1518. 
This spring had been wet and 

97
00:07:56,880 --> 00:08:01,480
cold, perfect conditions for 
Urquhart to flourish in the 

98
00:08:01,480 --> 00:08:07,160
city's rye fields. 
The poorest citizens, surviving 

99
00:08:07,160 --> 00:08:11,640
primarily on rye bread, would 
have consumed the highest toxin 

100
00:08:11,640 --> 00:08:15,920
concentrations. 
It's no coincidence that the 

101
00:08:15,920 --> 00:08:20,240
most afflicted came from the 
lower classes, their daily bread

102
00:08:20,440 --> 00:08:25,320
becoming their doom. 
Yet some researchers argue that 

103
00:08:25,360 --> 00:08:29,480
ergot alone cannot explain the 
perfect storm of horror that 

104
00:08:29,480 --> 00:08:34,679
descended on Strasbourg. 
While the fungus's effects are 

105
00:08:34,679 --> 00:08:38,280
devastating, they typically 
cause convulsions rather than 

106
00:08:38,280 --> 00:08:42,679
coordinated dance movements. 
The truth lies in a more 

107
00:08:42,679 --> 00:08:48,320
sinister combination, ergot 
induced convulsions interpreted 

108
00:08:48,320 --> 00:08:53,520
through the lens of mass 
hysteria, creating a feedback 

109
00:08:53,520 --> 00:08:57,440
loop of psychological and 
physiological terror that 

110
00:08:57,440 --> 00:09:01,280
transformed a simple fungal 
infection into one of history's 

111
00:09:01,280 --> 00:09:07,560
most macabre episodes. 
Among the more sinister theories

112
00:09:07,560 --> 00:09:10,080
lurks a tale of divine 
vengeance. 

113
00:09:10,760 --> 00:09:13,880
St. 
Vitus, martyred in the blood 

114
00:09:13,880 --> 00:09:19,440
soaked final days of Rome's war 
on Christianity, supposedly 

115
00:09:19,440 --> 00:09:22,720
reached through the centuries to
exact his revenge. 

116
00:09:23,160 --> 00:09:26,840
Them believed that Vitus 
supposedly cursed those who 

117
00:09:26,840 --> 00:09:32,360
denied his power, forcing them 
to dance until their feet bled 

118
00:09:32,400 --> 00:09:36,640
and their minds shattered. 
Their bodies, like puppets on 

119
00:09:36,640 --> 00:09:42,040
invisible strings, twisted and 
spun in a macabre ballet that 

120
00:09:42,040 --> 00:09:44,640
would only end when death 
finally granted them. 

121
00:09:46,000 --> 00:09:49,360
Whereas others will say it was 
related to socio political 

122
00:09:49,360 --> 00:09:54,760
stress during this period, 
poverty, disease, war and many 

123
00:09:54,760 --> 00:09:58,080
other hardships weighed heavily 
on those living there. 

124
00:09:59,680 --> 00:10:03,640
Could psychological strain have 
manifested into dancing 

125
00:10:03,800 --> 00:10:10,600
involuntarily to relieve stress?
Ultimately, some suggest that 

126
00:10:10,600 --> 00:10:13,600
the movements could have been 
caused by a neurological 

127
00:10:13,600 --> 00:10:18,880
disorder, possibly even related 
to epilepsy or another condition

128
00:10:18,880 --> 00:10:21,080
that wasn't understood at the 
time. 

129
00:10:23,440 --> 00:10:27,400
As the summer faded in 
Strasbourg that year, the 

130
00:10:27,400 --> 00:10:32,440
dancing finally ceased. 
The streets that had witnessed 

131
00:10:32,440 --> 00:10:35,680
hundreds of people dancing 
themselves to exhaustion and 

132
00:10:35,680 --> 00:10:41,000
death fell silent once again. 
But questions about this 

133
00:10:41,000 --> 00:10:44,000
extraordinary event have echoed 
through the centuries. 

134
00:10:44,880 --> 00:10:48,640
Was it mass hysteria triggered 
by the extreme hardships of 

135
00:10:48,640 --> 00:10:53,800
medieval life, Or a bizarre 
reaction to a fungal infection 

136
00:10:53,800 --> 00:10:58,280
in the local grain? 
Or was it something more 

137
00:10:58,280 --> 00:11:02,680
sinister, a supernatural force 
that possessed the bodies and 

138
00:11:02,680 --> 00:11:05,360
minds of these unfortunate 
souls? 

139
00:11:06,760 --> 00:11:10,920
Perhaps we just leave this to 
the unexplained realms. 

140
00:11:18,410 --> 00:11:22,850
What's particularly unsettling 
is that the dancing plague was 

141
00:11:22,850 --> 00:11:26,690
not isolated. 
Throughout medieval Europe, 

142
00:11:26,890 --> 00:11:31,290
similar episodes of mass dancing
occurred, like a contagious 

143
00:11:31,290 --> 00:11:33,690
rhythm that affected the human 
spirit. 

144
00:11:34,410 --> 00:11:36,250
Kind of like the track behind 
me. 

145
00:11:37,120 --> 00:11:39,960
That's Matt Large with his track
Alley Cats. 

146
00:11:40,160 --> 00:11:41,760
You can check him out on 
Spotify. 

147
00:11:44,320 --> 00:11:49,360
These events defied explanation 
then and continue to puzzle us 

148
00:11:49,360 --> 00:11:52,600
today. 
Perhaps the most chilling is the

149
00:11:52,600 --> 00:11:56,320
thought that our minds remain 
just as susceptible to mass 

150
00:11:56,320 --> 00:11:59,920
phenomena now as they were five 
centuries ago. 

151
00:12:00,800 --> 00:12:05,080
Social media feeds, viral trends
and mass movements show us that 

152
00:12:05,080 --> 00:12:08,480
human behavior can still spread 
like wildfire through a 

153
00:12:08,480 --> 00:12:11,400
population. 
The only difference? 

154
00:12:11,920 --> 00:12:15,800
Today, we dance through social 
media challenges instead of 

155
00:12:16,120 --> 00:12:20,440
village squares. 
Until next time, keep your eyes 

156
00:12:20,440 --> 00:12:24,360
open and watch your feet. 
You never know when the urge to 

157
00:12:24,360 --> 00:12:26,760
dance to your death you might 
strike.
