Political books dominated Marteau's production. The peculiar "Memoires pour rendre la paix perpetuelle en Europe" appeared at one of Marteau's rivals in Cologne: Jacques le Pacifique published their first volume in 1712 (Immanuel Kant would refer to the outline of a union of European states at the end of the century in his famous treatise on a permanent world peace). Politics could hardly be separated from entertainment. Anne-Marguerite Petit du Noyer published her political gossip under the ubiquitous label. The secrets of the diplomats negotiating at Utrecht were a bestseller. Political novels like "La Guerre d'Espagne" (Cologne: Pierre Marteau, 1707) were extremely influential — the book mixed fact and fiction, sections of newspaper history with personal adventures of its hero, a virtual James Bond in the services of Louis XIV.
