Abstract: Louis-Élisabeth de la Vergne, comte de Tressan (1715-1783) recast Antoine de La Sale’s Jehan de Saintré (1456) in “miniature” for the Bibliothèque universelle des romans in 1780. Close analysis of the author’s substantial revisions – cuts, explanatory footnotes, character development, narratorial interventions, and explicit reworkings of the plot – shows how Tressan refashioned a medieval courtly fiction to appeal to a broad range of eighteenth-century readers.
