When Michael Palin met the Dalai Lama a few years ago, the Tibetan leader said he recognised Palin from his television travel programmes. The two quickly discovered that they had shared a passion for geography from an early age. “It’s just an assumption but I felt a certain empathy when he was talking about how atlases were his favourite books when he was young and I said they had been mine too,” recalls Palin.

Palin met the Dalai Lama in Dharamsala in northern India, where he has lived in exile for nearly 50 years since fleeing China in a dramatic 15-day journey by foot. A few weeks later, Palin found himself in the Dalai Lama’s apartments in the Potala Palace in Lhasa while filming a series on the Himalayas. “Looking out over the city and the plains, I thought, ‘This is what he was doing growing up in the 1950s and there was me in Sheffield looking at an atlas also.’”
