Brief description -
The Bal des Ardents (Ball of the Burning Men[1]) or the Bal des Sauvages[2] (Ball of the Wild Men), was a masquerade ball[note 1] held on 28 January 1393 in Paris at which Charles VI of France performed in a dance with five members of the French nobility. Four of the dancers were killed in a fire caused by a torch brought in by Charles’s brother Louis I, Duke of Orléans.

A tragic event with drama and irony.

As I remember, he had to be sewn into his costume, no zipper in those days.
