In The Silk Road, Valerie Hansen describes the remarkable archeological finds that revolutionize our understanding of these trade routes. For centuries, key records remained hidden-sometimes deliberately buried by bureaucrats for safe keeping. But the sands of the Taklamakan Desert have revealed fascinating material, sometimes preserved by illiterate locals who recycled official documents to make insoles for shoes or garments for the dead. Hansen explores seven oases along the road, from Xi'an to Samarkand, where merchants, envoys, pilgrims, and travelers mixed in cosmopolitan communities, tolerant of religions from Buddhism to Zoroastrianism. There was no single, continuous road, but a chain of markets that traded between east and west. China and the Roman Empire had very little direct trade. China's main partners were the peoples of modern-day Iran, whose tombs in China reveal much about their Zoroastrian beliefs. Silk was not the most important good on the road; paper, invented in China before Julius Caesar was born, had a bigger impact in Europe, while metals, spices, and glass were just as important as silk. Perhaps most significant of all was the road's transmission of ideas, technologies, and artistic motifs.
