But by the fifteenth century, they had all but vanished, their fate confounding generations of archaeologists. But new research has revealed that it was the trade in walrus ivory that was behind both their prosperity and decline.In this edition of Gone Medieval, Dr. Cat Jarman talks to Professor James Barrett, to discuss an enterprise that traversed East and West, but ultimately crashed as stocks ran out and elephant ivory became more accessible.The Senior Producer on this episode was Elena Guthrie. It was edited by Thomas Ntinas and produced by Rob Weinberg. For more Gone Medieval content, subscribe to our Medieval Mondays newsletter here.If you'd like to learn even more, we have hundreds of history documentaries, ad free podcasts and audiobooks at History Hit - subscribe today!
