Andrew Graham-Dixon travels to the Yellow Mountains in southern China to understand the power of Chinese landscape painting. The period from the 10th to the 15th century - from the Song to the Ming dynasties - was the golden age of art in China. Andrew discovers an emperor so in love with art and beauty that he neglected to rule his country and scholar artists who fled the Mongol invasion to immerse themselves in nature, combining wondrous landscape painting and calligraphy. While Europe was still in the Dark Ages, Chinese art was being reborn.
