German anarchist Rudolf Rocker’s (1873-1958) little-known novel, Die Sechs (1938: The Six) is a philosophical allegory about a great and mysterious black marble Sphinx that stands in a desert. Six roads from widely separated lands converge on the desert sands; along these roads travel six well-known characters from world literature: Faust, Don Juan, Hamlet, Don Quixote, Medardus the Monk (from E.T.A. Hoffmann), and the bard Heinrich von Ofterdingen. The character of each is described individually (in the words of their creators) before meeting at the end to solve the ancient riddle of the Sphinx.
