After a decade of editorial work on the new historical-critical edition of the works of Ludwig Achim von Arnim (Weimar Arnim Edition, WAA), this volume collects the philological, literary, philosophical and comparative constellations gained so far. A new picture is developing of one of the “most original minds of the Romantic School?” (Heinrich Heine) illustrating his influence on his contemporaries and following generations, which was much more lasting than hitherto believed.
