Outline
Circulating message that features an image depicting a grave covered by a sturdy iron cage claims that the cages were used in Victorian times to keep vampires and zombies from escaping should they rise from the dead.
Brief Analysis
The claim in the message is fanciful nonsense. In fact, the cages were used to stop grave robbers from stealing corpses for use by medical students and anatomists. The cages – known as mortsafes – were regularly used in Scotland in the early 19th century.
Example

This is a grave from the Victorian age when a fear of zombies and vampires was prevalent. The cage was intended to trap the undead just in case the corpse reanimated.
