In 1974, farmers digging a well near Xi’an, China, uncovered bronze arrow heads and shards of pottery. Their discoveries led archeologists to the tomb of Ying Zheng (259-210 B.C.) first emperor of China. It’s been called the greatest archeological discovery of the 20th century: an army of 8,000 life-size terracotta warriors and horses. Now, some of these warriors are in Cincinnati for the first time.
