During the reign of the Roman Emperor Tiberius Caesar…

During the reign of the Roman Emperor Tiberius Caesar, between 14-37 AD, a craftsman created flexible glass which was shatterproof, and would only produce slight dents when dropped, which could be easily repaired with a hammer.
The Emperor, fearing that it would devalue gold and silver, had the craftsman executed. To this day no one knows how the legendary material was made.

King Charles VI of France, also known as Charles the Mad, suffered from the delusion he was made of glass. He even had protective iron bars sewn into his clothes to prevent him from shattering if he fell.
