A fear in historical recordsSourced
Some people feared that their bodies were made of glass
European records from the late medieval and early modern periods describe people convinced that their bodies were glass and could shatter. Charles VI of France is a noted example. Their bodies were not literally glass; the accounts preserve a fear expressed through a material familiar to the era.
An unusual historical belief could still involve real distress.
