Edgar Allan Poe explored the theme in “The Premature Burial,” published in 1844, a story that both reflected and amplified the cultural anxiety of his era.

The narrator of Poe’s story is paralyzed by terror at the prospect of being interred alive, a fear that Poe presents as not merely neurotic but as a response to documented realities:

“The boundaries which divide Life from Death are at best shadowy and vague.

Who shall say where the one ends, and where the other begins?”

This question — where does life end and death begin? — was not merely philosophical in the nineteenth century.

It was practical and urgent.
