Resumen:
This paper analyzes Ruperta and Croriano's episode included in Persiles (III, 16-17), by Cervantes, which exposes a case of female violence that is finally cancelled by the reassuring force of love and beauty. The nature of the story is discussed -it belongs to the category of "marvelous plausible" (maravilloso verosimil); its narrative structure is reviewed, and finally some notes on mythological and literary sources are offered. Altogether, the episode is a wonderful example of Cervantes' storytelling mastery.
