A distinguishing feature of Stendhal's novel, which is missing from many similarly detailed novels of realism, is its lightheartedness and humor. 'The Charterhouse of Parma' manages to craft complex characters without ever taking those characters too seriously. In addition, many of the minor characters, like Rassi and Ferrante, are effectively caricatures. Nevertheless, Stendhal accomplished this caricature without sacrificing the realism that made the novel so influential.
