== Relationship to the True story of the Bal des Ardents == 

 There is an event in 28 January 1393. Bal des Ardents, where Charles VI of France (the mad king of France) almost died dressed as hairy wild man (in resin-soaked costumes covered with flax to look like hair) along with 5 other members of the nobility in a dance at a party of the nobility  all chained together. The king's brother Louis, Duke of Orléans "accidentally" caused a torch to be brought to them and 3 of the dancers died and the king was wounded.  

 This is clearly the precedent for the Hop Frog story.
