We all want to make sense of this vast and messy world. From etchings on cave walls to sea charts, globes and atlases, humans have been making maps for thousands of years. Join map historian Jerry Brotton as he explores this fascinating world of maps. In each episode, we ask our guests to unfold a map that is special to them and tell us the story behind it. What's Your Map? Is an Oculi Mundi exploration. To look at the maps as they are discussed, go to http://Oculi-Mundi.com
