This is an assessment of how four humanists in the court of Pope Clement VII - Pietro Alcionio, Pietro Corsi, Jacopo Sadoleto and Pierio Valeriano - interpreted the cataclysmic Sack of Rome (1527), which called into question their earlier images of the Renaissance papacy. Building upon late-20th-century discussions in literary criticism and cognitive psychology, the author elucidates how these humanists' narratives gave meaningful shape to their memories and, in so doing, helped to redefine the image of Renaissance Rome as it would be "remembered" by subsequent generations.
