Did Giovanni Boccaccio, lady-loving author of the Decameron's bawdy tales, undergo a conversion that led him to write misogynistic biographies in his Latin work, On Famous Women? This narrative has been accepted for decades, but it leaves Boccaccio's supposed shift from philogyny to misogyny unexamined. This presentation will explore and challenge the narrative of Boccaccio's "conversion" by turning to the manuscript tradition of On Famous Women. Tracing authorial variations, scribal choices, and marginalia, we will reconsider Boccaccio's conversion and the terms that have been used to describe it. Is Boccaccio a philogynist or a misogynist? Or, perhaps, neither?
