A closer look

King Charles VI of France suffered from a bizarre psychological disorder in the late fourteenth century where he became completely convinced that his entire body was made of highly fragile glass. Terrified that he would spontaneously shatter into a million pieces if anyone touched him, the monarch refused to let his advisors approach him and had iron rods permanently sewn into his clothing to prevent his delicate torso from breaking. This bizarre psychiatric phenomenon actually became quite trendy among European aristocrats in the following centuries, with numerous nobles adopting the delusion as a sort of fashionable mental breakdown. Imagine having so much royal privilege and free time that your brain simply invents an entirely new anxiety disorder just to make sure the peasants keep a respectable distance from your fragile royal ego
