Jesuit Order. Kraus felt it was the weakest of all three anti-clerical works. Some satires refer to contemporary events, such as Monsieur Jacques à Paris during the Siege of 1870 (Monsieur Jacques à Paris während der Belagerung von 1870). Busch biographer Manuela Diers declares the story "tasteless work, drawing on anti-French emotions and mocking the misery of French people in Paris, which is occupied by Prussian troops". It depicts an increasingly desperate French citizen who at first eats a mouse during the German siege, then amputates his dog's tail to cook it, and finally invents an explosion pill which kills his dog and two fellow citizens. Weissweiler believes that Busch wrote with irony. In Eginhard and Emma (1864), a fictional family story that takes place in the Charlemagne era, he criticizes the Holy Roman Empire and calls for a German empire in its place; in The Birthday or the Particularists (Der Geburtstag oder die Partikularisten) he satirizes the anti-Prussian sentiments of his Hanover countrymen. Critique of the Heart Busch did not write illustrated tales for a while, but focused on the literary Kritik des Herzens (Critique of the Heart), wanting to appear more serious to his readers. Contemporary reception for the collection of 81 poems was mainly poor; it was criticized for its focus on marriage and sexuality. His long-time friend Paul Lindau called it "very serious, heartfelt, charming poems". Dutch writer Marie Anderson was one of few people who enjoyed his Kritik des Herzens, and she even planned to publish it in a Dutch newspaper. Adventures of a Bachelor Notwithstanding the hiatus after moving from Frankfurt, the 1870s were one of Busch's most productive decades. In 1874 he produced the short illustrated tale, Diddle-Boom! (Dideldum!). Following in 1875, was the Knopp Trilogy, about the life of Tobias Knopp: Adventures of a Bachelor (Abenteuer eines Junggesellen), Mr. and Mrs. Knopp (Herr und Frau Knopp) (1876), and "Julie" (Julchen) (1877). The antagonists of the trilogy are not pairs of nuisances as with Max and Moritz or Jack Crook, Bird of Evil (Hans Huckebein, der Unglücksrabe). Without pathos, Busch makes Knopp become aware of his mortality: Rosen, Tanten, Basen, Nelken Sind genötigt zu verwelken; Ach — und endlich auch durch mich Macht man einen dicken Strich. April, cousins, maidens, May Irretrievably decay; And I also, soon enough, Shall be cancelled and crossed off. In the first part of the trilogy, Knopp is
