What was it when they tied bells to corpses fingers?

Tying bells to corpses' fingers was a practice associated with the fear of premature burial, particularly in the 18th and 19th centuries. It involved attaching a bell to a finger or a string that led above ground, allowing a person who might have been mistakenly pronounced dead to signal for help if they regained consciousness. This practice reflected societal anxieties about death and the accuracy of medical assessments during that era. It is often linked to the term "safety coffin," designed to prevent such tragedies.
