There have been other authors who have written about these amoeba-like women – Maria Luisa Bombal and Esther Tusquets come to mind.
What’s really funny is that this is a relatively recent phenomenon. For instance, a nineteenth-century author called Pilar Sinués, who is considered ultra-conservative, openly mocks this type of women. I actually stole the expression amoeba women from her. In Sinués’s novels, women who are obsessed with making their husbands happy and who have no other interest in life are referred to as “things and not sentient creatures.”
And it’s not just Sinués. It was a widely accepted tradition in female literature, even that written by very conservative, Catholic authors, to mock women who have no interest in life aside from pleasing a man. It’s only recently that these boy-crazy eternally childlike women became a huge feminist ideal.
