Edward Jay Epstein recalls, in the fall of 1954, taking Lit 311: European Literature of the Nineteenth Century – unofficially called “Dirty Lit” for its emphasis on adultery – which was taught by Vladimir Nabokov:
I did not get around to reading any of Anna Karenina before Nabokov sprang a pop quiz. It consisted of an essay question: “Describe the train station in which Anna first met Vronsky.” Initially, I was stymied by this question because, having not yet read the book, I did not know how Tolstoy had portrayed the station. But I did recall the station shown in the 1948 movie starring Vivien Leigh. … Only after the exam did I learn that many of the details I described from the movie were not in the book. Evidently, the director Julien Duvivier had had ideas of his own. Consequently, when Nabokov asked “seat 121” to report to his office after class, I fully expected to be failed, or even thrown out of Dirty Lit.
What I had not taken into account was Nabokov’s theory that great novelists create pictures in the minds of their readers that go far beyond what they describe in the words in their books. In any case, since I was presumably the only one taking the exam to confirm his theory by describing what was not in the book, and since he apparently had no idea of Duvivier’s film, he not only gave me the numerical equivalent of an A, but offered me a one-day-a-week job as an “auxiliary course assistant.”
