They Properly Thought Theyd Shatter Like Glass
Category: Medical Oddities 30th May 2026
Alright, this one sounds like a bit of theatre, but it is proper history: for a while people actually believed they were made of glass. Not metaphorically. Literally. Theyd wobble about frightened theyd smash if someone bumped the table.
The fancy name scholars give it is the "glass delusion". You find it in records from late medieval and early modern Europe. The most famous chap who got it was King Charles VI of France. Bloke was convinced his body was fragile glass, so he wore reinforced garments and folks fussed over him like he was a teacup on a mantelpiece.
It wasnt just royalty being melodramatic. Physicians of the day wrote case notes about ordinary people too. Patients refused to sit down or allow touch, fearing they'd splinter. Some demanded padding, others forced themselves to move like a museum exhibit. Proper tragic, but also a bit daft when you imagine it.
Why it happened? People smarter than me reckon a mix of cultural vibes and anxiety. After plagues, wars and all that, societies got jittery. Glass was a new fashionable thing back then, very delicate and prized, so the idea of being breakable lodged in some heads. Scholars point to melancholy and religious fears as well. Dont take that as me saying its psychological slang-these were genuine, painful delusions.
The remedies were an odd blend of the medical and the theatrical. Doctors tried physical treatments, herbs, confession, even symbolic gestures to prove the person wasnt glass. Families padded chairs, dressed sufferers in heavy clothes, and generally treated them like antiques you couldnt risk.
I remember once hearing about folk who cling on to superstitions like a safety blanket. This was the full-on version: people turned fragile ideas into full-time jobs. Imagine being the servant whose shift is "dont let him knock the candlestick". Proper nightmare.
Its one of those human oddities that sits between medicine, culture and plain old fear. Ridiculous to us now, yes, but utterly real then. The world has always made room for daftness; sometimes it puts a velvet rope around it and sells tickets.
