A conversation with Ada Palmer (University of Chicago) about the invention of the idea of the Italian Renaissance and the functions that it serves in the western historical imagination. "Byzantium" is a similarly invented category that often works in tandem with "the Renaissance" to mark good and bad moments in the history of culture. The conversation is based on Ada's recent book, Inventing the Renaissance: The Myth of a Golden Age (University of Chicago Press, 2025). She is also an award-winning science-fiction author and one of the most successful and popular teachers at the University of Chicago, featured in the New York Times for the mock papal elections through which she teaches students about the inner workings of Renaissance politics.
