In March 1974, a group of peasants digging a well in drought-parched Shaanxi province in northwest China unearthed fragments of a clay figure—the first evidence of what would turn out to be one of the greatest archaeological discoveries of modern times. Near the unexcavated tomb of Qin Shi Huangdi—who had proclaimed himself first emperor of China in 221 B.C.—lay an extraordinary underground treasure: an entire army of life-size terra cotta soldiers and horses, interred for more than 2,000 years.
The site, where Qin Shi Huangdi's ancient capital of Xianyang once stood, lies a half-hour drive from traffic-clogged Xi'an (pop. 8.5 million). It is a dry, scrubby land planted in persimmon and pomegranate—bitterly cold in winter and scorching hot in summer—marked by dun-colored hills pocked with caves. But hotels and a roadside souvenir emporium selling five-foot-tall pottery figures suggest that something other than fruit cultivation is going on here.
Over the past 35 years, archaeologists have located some 600 pits, a complex of underground vaults as yet largely unexcavated, across a 22-square-mile area. Some are hard to get to, but three major pits are easily accessible, enclosed inside the four-acre Museum of the Terracotta Army, constructed around the discovery site and opened in 1979. In one pit, long columns of warriors, reassembled from broken pieces, stand in formation.With their topknots or caps, their tunics or armored vests, their goatees or close-cropped beards, the soldiers exhibit an astonishing individuality. A second pit inside the museum demonstrates how they appeared when they were found: some stand upright, buried to their shoulders in soil, while others lie toppled on their backs, alongside fallen and cracked clay horses. The site ranks with the Great Wall and Beijing's Forbidden City as one of the premier tourist attractions within China.
For those unable to make the journey to Xi'an, some of the choicest specimens unearthed there form the centerpiece of two successive traveling exhibitions that survey the reign of Qin Shi Huangdi (221 B.C.-210 B.C.). "The First Emperor," organized by the British Museum, debuted in London before moving to the High Museum in Atlanta. A second show, "Terra Cotta Warriors," then opened at the Bowers Museum in Santa Ana, California. It is now at the Houston Museum of Natural Science through October 18, and then moves to the National Geographic Society Museum in Washington, D.C. for display from November 19 to March 31, 2010.
In addition to showcasing recent finds, the exhibitions feature the largest collection of terra cotta figures ever to leave China. The statuary includes nine soldiers arranged in battle formation (armored officers, infantrymen, and standing and kneeling archers), as well as a terra cotta horse. Another highlight is a pair of intricately detailed, ten-foot-long bronze chariots, each drawn by four bronze horses. (Too fragile to be transported, the chariots are represented by replicas.) The artifacts offer a glimpse of the treasures that attract visitors from around the world to the Xi'an museum site, where 1,900 of an estimated 7,000 warriors have been disinterred so far.
The stupendous find at first seemed to reinforce conventional thinking—that the first emperor had been a relentless warmonger who cared only for military might. As archaeologists have learned during the past decade, however, that assessment was incomplete. Qin Shi Huangdi may have conquered China with his army, but he held it together with a civil administration system that endured for centuries. Among other accomplishments, the emperor standardized weights and measures and introduced a uniform writing script.
Recent digs have revealed that in addition to the clay soldiers, Qin Shi Huangdi's underground realm, presumably a facsimile of the court that surrounded him during his lifetime, is also populated by delightfully realistic waterfowl, crafted from bronze and serenaded by terra cotta musicians. The emperor's clay retinue includes terra cotta officials and even troupes of acrobats, slightly smaller than the soldiers but created with the same methods. "We find the underground pits are an imitation of the real organization in the Qin dynasty," says Duan Qingbo, head of the excavation team at the Shaanxi Provincial Research Institute for Archaeology. "People thought when the emperor died, he took just a lot of pottery army soldiers with him. Now they realize he took a whole political system with him."
Qin Shi Huangdi decreed a mass-production approach; artisans turned out figures almost like cars on an assembly line. Clay, unlike bronze, lends itself to quick and cheap fabrication. Workers built bodies, then customized them with heads, hats, shoes, mustaches, ears and so on, made in small molds. Some of the figures appear so strikingly individual they seem modeled on real people, though that is unlikely. "These probably weren't portraits in the Western sense," says Hiromi Kinoshita, who helped curate the exhibition at the British Museum. Instead, they may have been aggregate portraits: the ceramicists, says Kinoshita, "could have been told that you need to represent all the different types of people who come from different regions of China."
The first emperor's capital, Xianyang, was a large metropolis, where he reportedly erected more than 270 palaces, of which only a single foundation is known to survive. Each time Qin Shi Huangdi conquered a rival state, he is said to have transported its ruling families to Xianyang, housing the vanquished in replicas of palaces they had left behind. At the same time, the emperor directed construction of his tomb complex; some 720,000 workers reportedly labored on these vast projects.
Upon the death of his father, Yiren, in 246 B.C., the future Qin Shi Huangdi—then a prince named Ying Zheng who was around age 13—ascended the throne. The kingdom, celebrated for its horsemen, sat on the margin of civilization, regarded by its easterly rivals as a semi-savage wasteland. Its governing philosophy was as harsh as its terrain. Elsewhere in China, Confucianism held that a well-run state should be administered by the same precepts governing a family: mutual obligation and respect. Qin rulers, however, subscribed to a doctrine known as legalism, which rested on the administration of punitive laws.
In his early 20s, Ying Zheng turned for guidance to a visionary statesman, Li Si, who likely initiated many of his sovereign's accomplishments. Under Li's tutelage, Ying Zheng introduced a uniform script (thereby enabling subjects of vastly different dialects to communicate). Standardization, a hallmark of the Qin state, was applied to weaponry as well: should an arrow shaft snap, or the trigger on a repeating crossbow malfunction, the component could be easily replaced. The young ruler also presided over creation of an advanced agricultural infrastructure that incorporated irrigation canals and storage granaries.
With methodical zeal, Ying Zheng set about conquering the warring states that surrounded him in the late third century B.C. As his armies advanced, principalities fell. No one could thwart consolidation of an empire that eventually stretched from parts of present-day Sichuan in the west to coastal regions along the East China Sea. Having unified the entire civilized world as he knew it, Ying Zheng in 221 B.C. renamed himself Qin Shi Huangdi, translated as First Emperor of Qin.
He then invested in infrastructure and built massive fortifications. His road network likely exceeded 4,000 miles, including 40-foot-wide speedways with a central lane reserved for the imperial family. On the northern frontier, the emperor dispatched his most trusted general to reinforce and connect existing border barriers, creating a bulwark against nomadic marauders. Made of rammed earth and rubble, these fortifications became the basis for the Great Wall, most of which would be rebuilt in stone and brick during the 15th century A.D. under the Ming dynasty.
As the grandeur of his tomb complex suggests, Qin Shi Huangdi kept an eye on posterity. But he also longed to extend his life on earth—perhaps indefinitely. Alchemists informed the emperor that magical herbs were to be found on what they claimed were three Islands of the Immortals in the East China Sea. The emissaries most likely to gain entry to this mystical realm, they asserted, were uncorrupted children; in 219 B.C., Qin Shi Huangdi reportedly dispatched several thousand youngsters to search for the islands. They never returned. Four years later, the emperor sent three alchemists to retrieve the herbs. One of them made it back, recounting a tale of a giant fish guarding the islands. Legend has it that the first emperor resolved to lead the next search party himself; on the expedition, the story goes, he used a repeating crossbow to kill a huge fish. But instead of discovering life-preserving elixirs, the emperor contracted a fatal illness.
As he lay dying in 210 B.C., 49-year-old Qin Shi Huangdi decreed that his estranged eldest son, Ying Fusu, should inherit the empire. The choice undercut the ambitions of a powerful royal counselor, Zhao Gao, who believed he could govern the country behind the scenes if a more malleable successor were installed. To conceal Qin Shi Huangdi's death—and disguise the stench of a decomposing corpse—until the travelers returned to the capital, Zhao Gao took on a cargo of salted fish. The delaying tactic worked. Once Zhao Gao managed to return to Xianyang, he was able to operate on his home turf. He managed to transfer power to Ying Huhai, a younger, weaker son.
Ultimately, however, the scheme failed. Zhao Gao could not maintain order and the country descended into civil war. The Qin dynasty outlived Qin Shi Huangdi by only four years. The second emperor committed suicide; Zhao Gao eventually was killed. Various rebel forces coalesced into a new dynasty, the Western Han.
For archaeologists, one indicator that Qin rule had collapsed suddenly was the extensive damage to the terra cotta army. As order broke down, marauding forces raided the pits where clay soldiers stood guard and plundered their real weapons. Raging fires, possibly set deliberately, followed the ransacking, weakening support pillars for wooden ceilings, which crashed down and smashed the figures. Some 2,000 years later, archaeologists discovered charring on the walls of one pit.
Throughout recorded Chinese history, the first emperor's Ebang Palace—its site on the Wei River, south of ancient Xianyang, was not investigated until 2003— was synonymous with ostentation. The structure was said to have been the most lavish dwelling ever constructed, with an upper-floor gallery that could seat 10,000 and a network of covered walkways that led to distant mountains to the south.
"All Chinese people who can read, including middle- school students, believed that the Qin dynasty collapsed because it put so much money into the Ebang Palace," says archaeologist Duan. "According to excavation work from 2003, we found it was actually never built—only the base. Above it was nothing." Duan says that if the palace had been erected and demolished, as historians thought, there would be potsherds and telltale changes in soil color. "But tests found nothing," says Duan. "It is so famous a symbol of Chinese culture for so long a time, showing how cruel and greedy the first emperor was—and archaeologists found it was a lie." Duan also doubts accounts of Qin Shi Huangdi's expedition for life-prolonging herbs. His version is more prosaic: "I believe that the first emperor did not want to die. When he was sick, he sent people to find special medicines."
The emperor's tomb lies beneath a forested hill, surrounded by cultivated fields about a half-mile from the museum. Out of reverence for an imperial resting place and concerns about preserving what might be unearthed there, the site has not been excavated. According to a description written a century after the emperor's death, the tomb contains a wealth of wonders, including man-made streambeds contoured to resemble the Yellow and Yangtze rivers, flowing with shimmering, quicksilver mercury that mimics coursing water. (Analysis of soil in the mound has indeed revealed a high level of mercury.)
Yet answers about the tomb are not likely to emerge anytime soon. "I have a dream that one day science can develop so that we can tell what is here without disturbing the emperor, who has slept here for 2,000 years," says Wu Yongqi, director of the Museum of the Terracotta Army. "I don't think we have good scientific techniques to protect what we find in the underground palace. Especially if we find paper, silk or textiles from plants or animals; it would be very bad if they have been kept in a balanced condition for 2,000 years, but suddenly they would vanish in a very short time." He cites another consideration: "For all Chinese people, he is our ancestor, and for what he did for China, we cannot unearth his tomb just because archaeologists or people doing tourism want to know what is buried there."
Whatever future excavations reveal about Qin Shi Huangdi's enigmatic nature, some things seem unlikely to change. The emperor's importance as a seminal figure of history won't be diminished. And the mysteries that surround his life will likely never be completely resolved.
