Yes, very seriously.....
On just an ordinary July day in Strasbourg 1518, a seemingly sane woman named Frau Troffea walked out onto a street and started to dance, yep dance. Alright pretty normal thus far, the poor lady just felt like a little jig right? Now thats all well and good, but something isnt quite 100% when that same lady continues her jig for 6 days straight! The lady is clearly mentally unwell though, isn't she? and this is where the story ends? Well as many of us have come to know, the simplest answer isn't necessarily the right answer.... Over the next week 34 people joined her out on that very same street, forming the first ever street dance crew! Within a month 400 were shimmying down the streets of Strasbourg, and (i assume) everyone else in town was terrified with this legion of dancers who could not be persuaded to stop. As this continued just about everyone of the 400 people had danced themselves to death from either heart attack, stroke or exhaustion. But why?
The Tarantella. Originating in the historical southern Italian region of Taranto, it is now considered just a nice little folk dance, its roots though, are planted in something far more terrifying. Something that may well explain the events of 1518. The dance itself is the result of a condition referred to as Tarantism. You see Taranta was teaming with poisonous spiders affectionately named Lycosa Tarantula. The spiders venom, (lets just see if this sounds familiar to you) is said to have the following effect, "an irresistible need for a a wild and rapid twirling motion bringing the victim to the point of exhaustion". Now your thinking, "yeah that all sounds plausible, but how did the spiders get all the way from the south of Italy to the north of France?" Well, with further research i looked up european trade routes from around the same time and what do you know? There are some very direct trade routes between the two cities! See for yourself....
