Greg Jenner is joined by Dr Stephen Kershaw and comedian Sophie Duker to dive into the myth of Atlantis. The Atlantean story has its origins in the writings of the ancient Greek philosopher Plato. And literally nowhere else. Yet the enduring appeal of this mythical city and a sophisticated civilisation lost beneath the waves has lasted for thousands of years. It has inspired a huge number of stories and some very ropey documentaries. The myth also has a darker side, as the allegory of Atlantis has been used to try and justify racist philosophies and policies during some of the darkest events in history.
