Free-form satire, emancipated from strictly Horatian / Juvenalian models, and organized around a poetic “I”, distant, critical or even indignant before a changing world, played an important role in the emergence of news writing in Early Modernity, leading to the onset of the periodical press in the 17th century. In order to reflect on the connection between Early Modern information media, and satirical or militant writing, the idiom “fake news”, while seemingly incongruous at first, is in fact particularly useful, as it helps establish a connection with our contemporary practices, such as incorrect news, ideologically-oriented publications, clickbaits, and ironic parodies. By comparing these apparently heterogeneous phenomena, it becomes possible to think, in a coordinated way, about three aspects of the exchanges and hybridization that took place between Early Modern “occasionnels” (short, topical brochures) and “libelles” (satirical or libellous tracts). Like contemporary “fake news”, a term often used by purveyors of equally debatable reports to decry doubtful information produced by the opposing camp, libelles were always entangled in a network of other libelles, ever expending due to the indignation caused by the enemy’s lies. Libelles imitated news writing, feeding on rumors, and led to demystifications that often doubled as critiques of the codes of topicality found in the occasionnels. In certain ways, such criticism contributed to the creation of these codes, by pushing back against them. The forms taken by this satire of ideologically-oriented, or militant news writing went beyond partisan intent; it was sometimes difficult, as it is nowadays on certain satirical websites or social media accounts, to distinguish between activist creative writings, and playful games of wit. At a deeper level, satirical esthetics, whether grotesque (referring to the whole period) or burlesque (referring to its end), could instigate a global exercise of incredulity or unbelief towards the religious and political foundations of the Ancien Régime. On account of such a meta-reflexive dimension, of its great diversity linked to its hybridization of news writings, of its oscillation between partisan and playful humour, depending on the readership’s liking and the publishing industry’s interests, libelle referred to changeable forms quite similar to the fickle realities the moniker fake news refers to nowadays. Conversely, the libelle invites us not to hastily reject one aspect or another of the current network, which might be more homogeneous than it seems at first sight.
