This article focuses on Ruy Paez de Ribera, Florisando (1510, Book VI of the Amadis cycle), the first romance of the heterodox branch of the Amadis cycle. In particular, this article studies the intertextual relation of Florisando with Garci Rodriguez de Montalvo’s Sergas de Esplandian (1510, Book V). Paez characterized this relationship as one of narrative battles, as his romance contests several aspects of Sergas. The author harshly criticized Montalvo for not offering an adequate model for Christian chivalry. The belligerent characterization of Florisando underscores the ideological and narrative differences introduced by Paez to the cycle. Furthermore, Florisando appears as the winner of the narrative battle with Sergas as a means to justify the new interpretation that Paez made of the cycle. The literary elements that define Florisando’s victory paradoxically derive from Montalvo’s romances.
