18. Another of France’s most powerful men was a notable sufferer of the glass delusion

Again, this was not an isolated case of a well-to-do gentleman believing that they were made out of glass. Indeed, several decades after Charles VI had suffered from his glass delusion, the psychiatric disorder was once again seen in France. This time around, the sufferer was Nicole du Plessis. Not only was he rich, he was also incredibly well-connected. Family ties to Cardinal Richelieu, the power behind the French throne, gave him influence and power. Du Plessis should have felt indestructible. Instead, he felt fragile and at risk of being shattered into a million pieces.
