In this episode, Jerry takes another excursion to meet with Kanien’kehá:ka (Mohawk) and English visual artist, Hannah Claus. 

Hannah is in London exhibiting at the High Commission of Canada in the U.K. as part of their commitment to show work by Indigenous Canadian artists. Her body of work titled tsi iotnekahtentiónhatie - éntie nonkwá:ti [where the waters flow - south shore] tells the story of the Kahrhionhwa’kó:wa [the Great River, or Saint Lawrence River]. Her artwork éntie nokwá:ti ne Kaniatarowánen [water song - south shore] features as her chosen map for this episode: it is an installation that visualises a sound wave of a water song composed by Ionhiarò:roks McComber.

During this intimate tour of Hannah’s artworks, she tells Jerry about First Nations cosmologies and the importance of having a relationship to the land and bodies of water upon which one resides. Together, they delve into the concept of what constitutes a map, and how artists convey the narratives and collective histories of specific places through their work.

In the first episode of Season 4, our host Jerry Brotton finds himself at one of the world's largest and most active exploration-focused institutions: the Royal Geographical Society (RGS) in London. He meets with Cartographic Collections Manager Dr. Katie Parker to pore over a mid-sixteenth century treasure that both the RGS and The Sunderland Collection are privileged to own an example of. 

Produced in around 1550, this atlas by Battista Agnese is a luxurious curation of 13 hand-drawn portolan charts of the known world. Jerry and Katie explore what these exquisite maps show, and who would have owned them. They discuss the European desire for imperial expansion in pursuit of wealth, from silver and gold in the west to spices in the east. We also learn more from Katie’s expertise in 18th-century European maritime history and Pacific voyages of exploration.

Jerry journeys to the Arctic polar region with Dr Djoeke van Netten from the University of Amsterdam, following the attempts by Dutch navigator Willem Barentsz and his crew to reach China via the northeast passage.

Djoeke explains the backstory of the Dutch trade missions that took place in 1594, 1595, and 1596 and how the 1596 mission was stranded in Novaya Zemlya [an island chain in present day Northern Russia]  for almost a year.

These European explorers kept fascinating records of landscapes and animals that they had never encountered before, in particular polar bears—an animal that sparked significant curiosity and concern among the Dutch crew. Djoeke reveals how these interactions not only informed the crew's survival strategies but also shaped their perceptions of the Arctic.

Djoeke and Jerry discuss how maps not only record known geography but also convey what was unknown to European mapmakers - dotted lines and empty regions that reflect both an acknowledgment of limits and the ambition of further exploration.

Jerry interviews Melbourne based artist-cartographer Anton Thomas, who discusses his latest project: a meticulously hand-drawn world map titled "Wild World." Wild World centres the animal kingdom, showcasing over 1,600 animals across a world without national borders.

This intricate artwork emerged from Anton’s deep-rooted passion for mapping, which reaches back to his childhood. It also reflects his belief in the profound connection between humans and nature. 

Anton walks Jerry through the artistic and cartographic choices he made whilst drawing Wild World, a process that took several years to complete. We hear about how Anton wanted to shape the viewer’s experience, turning the map into a celebration of biodiversity while instilling a sense of optimism amid today’s environmental concerns.

Jerry and University of Denver Professor Susan Schulten delve into the groundbreaking work of Richard Edes Harrison, an artist cartographer whose innovative mapping style emerged in the tumultuous early 20th century, particularly during the lead-up to World War II. 

They discuss two of Harrison’s maps published in Fortune magazine, the business magazine founded by Henry Luce in 1929. Harrison’s maps challenged Americans' isolationism at the start of World War II. He wanted to shake the country out of what he called their “cartographic lethargy”.  

Susan walks us through the debates around the US entering World War II and the compromise that was reached – Lend lease, a policy that allowed the US to aid allies without entering the war themselves.

We also hear about Susan meeting Harrison at the end of his life and the valuable insight she got from him about the science and art of map making.

Neuroscientist and Harvard Professor Jeff Lichtman walks Jerry through his astonishing work mapping the human brain. In 2024, with the help of Google Research, Jeff’s team developed the most detailed map of a human brain sample ever created, producing 1,400 TB of data from a sample the size of a pinhead. 

Jeff also talks about how he and Harvard biologist Dr Joshua Sanes pioneered the Brainbow process, a breakthrough that allows scientists to easily identify individual neurons in the brain by colour.

He goes on to explain how our experiences allow us to build neural maps, or wiring diagrams, onto our brains. These maps encode our memories and learned experiences, so that we can act without thinking, like riding a bicycle.

In this episode, Jerry visits the Library of Congress in Washington DC to meet senior librarian Iris Taylor, who has nearly five decades of experience in the map department.

Iris shows Jerry a series of beautiful pictorial maps, created in the 1940s by the pioneering geographical storyteller Louise E. Jefferson. In particular, she highlights a map of ‘Americans of Negro Lineage’ from 1946. This map showcases notable African-Americans from throughout history, including figures like Harriet Tubman - who helped establish the Underground Railroad for escaping slaves - and the poet Langston Hughes. 

Louise was one of the first female African-American cartographers. Her work was long neglected, and Iris is working to bring it back to light.

In this conversation, Iris reflects on her discovery of the Jefferson maps, and the profound impact they have had on her. She also talks about her own personal journey as a librarian at the largest and most comprehensive map collection in the world.

Welcome to What’s Your Map? In this episode, Jerry speaks to Elizabeth Hogan, a marine biologist, Programme Director at the National Geographic Society, and a passionate advocate for marine conservation. 

Having spent over 15 years dedicated to protecting marine ecosystems, Elizabeth shares her experience while discussing a unique map that reorients our understanding of the world's geography.. She explains how this ocean-centric map from the Environmental Systems Research Institute illustrates the reality of our planet's interconnected bodies of water: that we have one global ocean rather than distinct, isolated seas.  

Elizabeth also reveals the significance of ocean currents, which are prominent on the map. She explains how they link distant regions, affecting everything from the migration patterns of marine species to the transportation of plastic waste, and the lives of coastal communities.
