As commerce flourished along the Silk Road, Central Asia became a melting pot of cultures. Here on the edges of the Taklmakan Desert, an exotic blend of Indian, Mongol, Chinese, and European influences fueled an astonishing cultural Renaissance. In the 7th century, a Chinese monk, Xuanzang, plunged into the desert while on a Buddhist pilgrimage to India. His descriptions of the oasis-cities he encountered would prove invaluable to another explorer, more than a thousand years later. 20th century archeologist Sir Aurel Stein took on the deadly Taklamakan to prove his own theories about Western China's lost civilization. Again and again Xuanzang's writings led him to archeological treasure - once thriving cities now buried in the sand. On their monk's trail, Stein made his greatest discovery, a thousand-year-old Buddhist library in near-perfect condition.

Historians have long speculated that thousands of wooden ships plied a Maritime Silk Route from the Middle East to China, braving long distances on white-capped seas, but time and the deep ocean have destroyed any evidence . . . until now.

As we uncover clues and reveal the story of the wreck, reenactments transport us back in time to an age of the legendary Sinbad the Sailor, when vicious seas ravaged wooden boats like matchsticks.
