The Three Leaps of Wang Lun ("Die drei Sprünge des Wang-lun") is a historical novel by German author Alfred Döblin that narrates upheaval and revolution in 18th-century China.
 Published in 1916 (although back-dated to 1915), this epic historical novel was Döblin's third novel (although it was the first to be published as a book), and garnered him the Fontane Prize.
 Favorably received by critics, who praised its detailed and exotic depictions of China, it was a literary breakthrough for Döblin.
 "Wang Lun" also had an influence on younger German writers, including Lion Feuchtwanger, Anna Seghers, and Bertolt Brecht; for the latter, "Wang Lun" provided an impulse for the development of the theory of epic theatre.
 In commercial sales, it is Döblin's most successful novel after "Berlin Alexanderplatz".
 The title of the novel refers to the rebel leader Wang Lun.

Mason & Dixon is a postmodernist novel by U.S. author Thomas Pynchon published in 1997.

Wallenstein is a 1920 historical novel by German author Alfred Döblin.
 Set in Central Europe during the Thirty Years War, the novel's plot is organized around the polar figures of Ferdinand II, Holy Roman Emperor, on the one hand, and Albrecht von Wallenstein, on the other.
 Döblin's approach to narrating the war differed from prevailing historiography in that, rather than interpreting the Thirty Years War primarily as a religious conflict, he portrays it critically as the absurd consequence of a combination of national-political, financial, and individual psychological factors.
 Döblin saw a strong similarity between the Thirty Years War and the First World War, during which he wrote "Wallenstein".
 The novel is counted among the most innovative and significant historical novels in the German literary tradition.
 In large part, contemporary critics found the novel to be difficult, dense, and chaotic—a reception Döblin discussed in his 1921 essay "The Epic Writer, His Material, and Criticism"—yet writers such as Lion Feuchtwanger, Franz Blei, and Herbert Ihering praised "Wallenstein" for its formal innovation, poetic language, epic scope, and bold departure from other German writing of the time.
 Despite the novel's difficulty, the critical consensus was that "Wallenstein" was a major achievement and confirmed the promise seen in Döblin's earlier historical novel, "The Three Leaps of Wang Lun".
