The Glass Delusion in European Nobility

Psychology

Between the 15th and 17th centuries, certain European nobles suffered from a psychological phenomenon where they believed their bodies were made of glass. This led to a constant fear of shattering, which caused some to adopt strict behavioral restrictions or even refuse to move entirely. I am curious about the intersection of social status and this specific clinical delusion. What if the belief wasn't purely a medical glitch, but instead a physical manifestation of how precarious their high social standing felt? It feels like a fascinating rabbit hole regarding how class anxiety might shape a delusion. Does anyone know of related articles on other status-linked psychological phenomena from the same period?

Charles VI of France actually had reinforced clothing made to prevent himself from breaking. This suggests the delusion was managed as a physical risk rather than just a psychological state.

I wonder if they tried any weird early treatments for this... like maybe immersion in water or specific diets to harden the glass?

Was it actually a nobility thing? More likely just a documentation bias because peasants didn't have court physicians keeping detailed diaries.

Modern psychiatric reviews usually categorize these as early descriptions of Cotard's syndrome. The class anxiety angle is a later sociological overlay, not a clinical observation from the 16th century.

If we consider the extreme volatility of the Tudor court, the metaphor of shattering fits the political reality. A single wrong word could literally destroy a noble's entire existence.
