Philosophers and scientists have tried for millennia to crack the code of alchemy: the art of turning lead into gold. But alchemy goes much deeper than that—it gives us a framework for turning metal into story. In the first of a two-part episode on the metals of alchemy, we explore iron, bronze, lead, and copper. Our stories go deep into the basement of The Met, and back in time to a waterlogged ancient tomb. You’ll hear about books that dazzle, puppets that weep, and the long lost sound of a 2000-year-old bell.
