Benvenuto Cellini was the bad boy of the Renaissance! His life was a story of murders, violence, war, the sack of cities, sodomy, imprisonment, religious conversion, prodigious artistic talent and writing one of the greatest artistic autobiographies of all time. Jerry Brotton, Professor of Renaissance Studies at Queen Mary University of London, has recently made a superb series for the BBC called The Essay, Blood and Bronze which charts the sometimes mad life of Cellini. He joins Dan to discuss Cellini's life, work and the mystery of a recently discovered Cellini painting.
