By filming on the actual locations traversed by Marco Polo, the series brings to life the authenticity of the local peoples from the standpoints of ethnology, historiography, culture and economics. We follow the exact route depicted in his book, Il millione, documenting the peoples, customs and cultures along the way to bring into sharp relief the cultural differences within the Asian mainland. Viewers are introduced to their development, becoming familiar with three completely different and, to us, relatively unknown spheres of civilisation and religion - Arabic Islam, Indian Hinduism and Oriental Buddhism. The host takes us through regions and cultures that may seem exotic - and, at times,dreamlike - in our search for the evidence of Marco Polo's passage.
