Glass Delusion in Early Modern Europe

History
I've been digging into the French Wikipedia entry on "Illusion de verre," which documents the glass delusion prevalent among European nobility between the 15th and 17th centuries. This is a classic example of a somatic delusion (a belief that one's body is altered in a way that contradicts physical reality). Sufferers were convinced they were made of glass, leading to an intense, paralyzing fear of shattering. The records regarding King Charles VI of France are particularly striking. He went so far as to wrap himself in blankets to provide a buffer against potential breakage. It is a wonderful illustration of the specific ways psychiatric disorders were recorded and interpreted in early modern history. This resource is useful for anyone mapping out the history of mental health. I highly suggest linking this to articles on Renaissance medicine or the history of psychiatry to provide more context on these historical anomalies.

While the behavioral symptoms align with somatic delusions, categorizing it strictly as such may be anachronistic. Early modern beliefs regarding glass often integrated theological notions of purity or spiritual fragility, which differs from a modern psychiatric somatic delusion.

What is the actual sample size for these cases? It is difficult to tell if this was a legitimate trend or just a few high profile anecdotes that historians amplified.

This is less about medicine and more about the performance of fragility. Modern anxiety is just the 21st century version of wrapping yourself in blankets to avoid a mental shatter.

It is interesting that we still use the metaphor of shattering to describe emotional breakthroughs or breakdowns. It suggests a deep, enduring human connection between physical fragility and mental state.

The social media comparison is a reach. There is a practical difference between curated online profiles and a person who physically fears breaking into shards.

The French archives mention how these beliefs sometimes spread through the court... I wonder if it was a form of social contagion? Did other nobles start mimicking the behavior to align with the king...

The article also notes that this wasn't exclusive to the nobility. There are records of commoners experiencing similar delusions, though they were rarely documented with the same precision as Charles VI.
