When People Thought They Were Made of Glass

In 1422, King Charles VI died after ruling France for more than 40 years. He was also remembered as Charles the Mad, in part because he was convinced that his body was made of glass and would shatter upon contact with other people. This condition, known as the glass delusion, would continue to pop up through medieval Europe until the late 19th century, seemingly disappearing in the modern day.
