Abstract: This article studies how the Chanson de Bertrand du Guesclin uses epic effects to serve its discourse and narrative structure: the rhetorical marking of episodes, rhetorical marking internal to the stanzas, where disjunctions of the text occur between its different versions, suggesting autonomous circulation of episodes to be integrated or not into the Chanson; and rhetorical and literary aspects characteristic of the growing influence of the genre of the novel in the long account of the Spanish campaign.
