In the nineteenth century the love of books leads to rediscovering seventeenth-century poets whose works have never been published in collections. When stopping this “gap” two centuries later, the job of publication, composition and recomposition at the same time, is far from being neutral. (Re-) constituting the poet’s work is simultaneously (re-)constituting an author’s figure which sometimes corresponds less to historical facts than to his modern publisher’s project, as shown by the examples of the poets Motin, Des Yveteaux and Lingendes.
