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 historian Jerry Brotton as he explores the 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. Celebrated historian William Dalrymple will join Jerry for our first episode on September 25th to discuss a beautiful map from the ancient Indian religion of Jainism.    What's Your Map? Is an Oculi Mundi exploration. To look at the maps as they are discussed, go to Oculi-Mundi.com  Produced by Emily Uchida Finch at Whistledown Productions.
