“Any minute now the world streams over its border” (Ot-ot gist zikh shoyn iber di velt bizn rand). So writes Soviet Yiddish poet Peretz Markish, a single resonant line among the hundreds in his eighty-page poem The Man of Forty (Der fertsikyeriker man), which his wife smuggled out of Stalinist Russia in a potato sack in 1949. Had she not done so it would surely have been seized by Stalin’s agents, who were moments from arresting the dissident poet when she departed.
