But has the glass delusion gone for good? Perhaps not. Research carried out in the Netherlands has found that, while it went out of fashion, there were still some cases of glass delusion well after the 1830s.

Most intriguing is a case dating from the 1930s – a full century after it’s widely acknowledged the glass delusion vanished for good.
