Sylvia Plath
It makes sense to start with the theory’s namesake, I think. For those of you who haven’t read The Bell Jar, it’s a thinly disguised autobiography about one girl’s spiral into depression including suicide attempts, hospital stays and shock treatment therapy.
The bell jar is used as a metaphor for the feeling the main character has when she’s going through her depression – she feels like she’s trapped under a bell jar, stifled and numb. Sylvia predicted her own future when she wrote from the perspective of her protagonist – “How did I know that someday – at college, in Europe, somewhere, anywhere – the bell jar, with its stifling distortions, wouldn’t descend again?”
Despite marriage, children, a successful career as a poet and a promising one as a novelist, Sylvia’s own bell jar did descend again. On February 11, 1963, she killed herself by putting her head in the oven with the gas on.
