page 756 of 818 of Fortunata and Jacinta: Two Stories of Married Women

You could make a case for this being a novel about (in part) mental illness. Mauricia went mad, Maximiliano went mad, Ido slips back and forth (usually when eating meat), Jacinta even had a spell where she obsessed about that little boy. Everyone is fevered, passionate, stuck in some mode of thinking they can’t escape (like Olimpia’s “piece”).
