Alfred Döblin’s great novel Berlin Alexanderplatz, published in 1929, is pretty much untranslatable. Much of it is written in the working-class argot of pre-war Berlin. A translator can ignore this, of course, and use plain English, but then you lose the flavor of the original. Or he can go for an approximation, adopting a kind of Brooklynese, for example, but this would not evoke Döblin’s louche Berlin milieu so much as Damon Runyon’s New York.[1] John Gay’s Beggar’s Opera, set in eighteenth-century London, was successfully reworked by Bertolt Brecht and Kurt Weill into a Weimar Berlin masterpiece, but that wasn’t a translation; it was a transformation, of place and time.
