In 2018, I did an experiment in seeing how the Fortnightly Books were distributed, globally. What I decided on was the country of the author. That's not always useful for ancient authors -- there's no real sense in which St. Maximus Confessor is an Israeli author, despite having been born within the modern borders of Israel. It also runs into problems with British literature, because the authors who contribute to what we think of as British literature are born all over -- Kipling and T. H. White were born in India, J. R. R. Tolkien was born in South Africa, etc. One can make sense of Kipling as an Indian author, but it's literally just happenstance that Tolkien was born in South Africa, and it has nothing to do with his literary work. Nonetheless, birthplace of author (sometimes probable birthplace), as determined by modenr borders, turned out to be the best way to do it, for the most part. I was thinking about it recently, so here I have updated it to the most recent Fortnightly Book, Flaubert's Sentimental Education.
