Stifter's "Der Nachsommer" (1857) and Gottfried Keller's "Die Leute von Seldwyla" ("The People of Seldwyla") were named the two great German novels of the 19th century by Friedrich Nietzsche. "Der Nachsommer" is considered one of the finest examples of the Bildungsroman, but received a mixed reception from critics at the time. Friedrich Hebbel offered the crown of Poland to whoever could finish it, and called Stifter a writer only interested in "beetles and buttercups." The excessive detail for which Hebbel derided the novel, is, according to Christine Oertel Sjögren, "precisely a source of fascination for modern scholars, who seize upon the number of objects as the distinguishing characteristic of this novel and accord it high esteem because of the very significance of the 'things' in it. Far from being extraneous elements, as Hebbel regarded them, the art and nature objects provide a rich setting of beauty and a mirror-background to the human story in the foreground." :20
