Near midnight on a Friday in April 1854, Gustave Flaubert wrote one of his many letters to Louise Colet. Flaubert had spent days hidden away in his Croisset retreat, researching theories of clubfoot and discarding pages from the manuscript of “Madame Bovary,” and he told Colet that he had come to the conclusion that “the books from which entire literatures have flowed, like Homer, Rabelais, are encyclopedias of their time. They knew everything.” This conception — the novel that knows everything — would come to obsess Europe’s modernist writers, who dreamed that a narrative of infinite detail and esoteric knowledge could blur the boundaries between traditional genres, with fiction shading into nonfiction, poetry bleeding into history.
