In this episode, Jerry speaks with Dr. Rohini Rai, a sociologist of race, ethnicity, and migration, and lecturer at Brunel University in London. She is also the co-founder of the Critical Himalayan Collective, a scholarly, activist network focused on reimagining Eastern Himalayan studies through Indigenous knowledge, art, and critical dialogue.

Rohini shares a map from the Royal Geographical Society Collections showing the colonial borders imposed on her home, Sikkim. The ‘Sketch Map of Sikkim and parts of Darjeeling, Nepal, Tibet and Bhutan’ was initially produced to accompany a report of a British surveying expedition in 1884-1886 led by Colonel Tanner.

We learn about Rohini’s research on the politics of the Eastern Himalayas and Himalayan diaspora in the UK. We also hear about Rohini's personal history in the region and the inspired projects using embodied practices like dance to reclaim colonised archival materials and remap ancestral lands.

From historians, scientists and writers, to creatives and cultural custodians, people have used maps as a source of knowledge, guidance, and inspiration for centuries.

This week, Jerry meets Ross Perlin, a linguist, writer, and translator focused on exploring and supporting linguistic diversity. Ross is the co-director of the Endangered Language Alliance (ELA), a non-profit organisation dedicated to documenting Indigenous, minority, and endangered languages, and supporting a mosaic of languages in New York City - Lenapehoking and beyond.

Ross shares an incredible interactive map (www.languagemap.nyc) that illustrates the rich tapestry of languages in New York with a focus on language at risk of disappearing. We delve into the City's foundational language, Lenape, and trace the journeys of native speakers and inspiring revitalisation projects for some the 700 languages that thrive and survive in New York.

As well as learning about some of the challenges of mapping and preserving languages, the questions around AI and language legacy, we also hear about Ross’ career in linguistics. This includes his language investigations in the Eastern Himalayas and the influence of his mentor, eminent linguist Hongkai Sun.

This week, Jerry meets Dr. Richard A. Pegg, the Director and Curator of Asian Art at the MacLean Collection, Asian map aficionado, and proud owner of Blue China Map shoes!

The MacLean Collection is an astonishing private collection of Asian art and global cartography. Based in Chicago, it is home to over 5,000 historic artefacts and more than 35,000 maps.

In this episode, Richard and Jerry discuss two majestic maps from the Qing Dynasty, known colloquially as the ‘Blue China Maps’: the ‘Complete Geographical Map of the Everlasting Qing Dynasty’ by Huang Qianren (pron. Hwang Chien-ren) (c.1820) and the ‘Complete Celestial Chart of Equatorial Fixed Stars’ by Yunyou Sanren (pron. Yün-yo (like a German ü) San-ren) (c.1822).

Richard explains the complex world view behind these maps and what they would have meant to someone consulting them in tandem during 19th Century China. He reveals how they were made, the source of their stunning blue colouring - and how they reflect the imperial Mandate of Heaven.

From historians, scientists and writers, to creatives and cultural custodians, people have used maps as a source of knowledge, guidance, and inspiration for centuries.
