On July 1518, a woman by the name of Frau Troffea began to viciously dance in the streets of the urban center of Strasbourg, France, in full view of her neighbors. There was no music to dance to as her face showed no expression of enjoyment, she seemed unable to stop herself from the delirium. If the incident had remained isolated the city elders might have deduced it a case of madness or demonic possession.
