In the four decades since mysterious terra-cotta statues first came to light in northern China, archaeologists have uncovered a whole lifelike army. But that wasn’t the only secret hidden underground there. Stunning revelations are now rewriting the history of the great ruler who created this army as part of his final resting place. And a radical new theory even suggests that foreign artists trained his craftsmen. 
 
 Known today as the First Emperor, Qin Shi Huang Di left a legacy that would make him a towering figure in Chinese history. By the time he died in 210 B.C., he had united warring kingdoms into one country, put an end to feudalism, and built the Great Wall that endures today as a monument to his power. 
 
 China's Terra-Cotta Warriors The explore team visits the tomb of the Terra-Cotta Warriors and Horses, where there is a ceramic army of as many as 8,000 life-sized, intricately carved statues modeled after Emperor Qin's army. 
 
 But his most stunning project first came to light in 1974 when farmers uncovered strange figures while digging a well near the old Chinese capital of Xianyang. Excavations have since revealed sections of a grand funerary complex. Three huge pits harbor several thousand warriors, presumably meant to protect the emperor for eternity. These statues were unlike anything ever uncovered before in China. And that raises a big question: How could the royal artists have come up with such an idea?

 Scientists have gathered a variety of provocative clues: Terra-cotta acrobats and bronze figures of ducks, swans, and cranes uncovered at the royal tomb complex may show evidence of Greek influence. And European DNA has been recovered from skeletons at a site in northwestern China. 
 
 Putting these together, experts have worked out a theory: Inspiration for the terra-cotta army may have come from foreign artists. Traveling from Hellenized areas of Western Asia and arriving in China 1,500 years before Marco Polo, they could have trained the local craftsmen who furnished the emperor’s tomb with statuary.

 China's Megatomb Revealed 
 
 Scientists using remote sensing, ground-penetrating radar, and core sampling have also revealed the emperor’s tomb complex to be much larger than once believed—almost 38 square miles (some 98 square kilometers). At its heart stands a tall earthen mound that covers the ruler’s tomb, which remains sealed. Many other people were also buried at the site. Archaeologists have discovered mass graves that appear to hold the remains of the craftsmen and laborers—including convicted criminals in chains—who died during the three decades it took to create the royal mausoleum. Other mass burials seem to tell grisly tales of a brutal struggle to capture the emperor’s throne.

 Chinese Game of Thrones 
 
 Despite the brilliance and power of the First Emperor, he was unable to make sure his eldest son succeeded him. It was a failure that had devastating consequences. Experts now believe it may have launched a bloodbath—and ultimately brought a swift end to the dynasty that Qin Shi Huang Di founded. 
 
 An account written in about 89 B.C. by Sima Qian, an official in the second dynasty, describes a time of deadly palace intrigue: One of the emperor’s many sons conspired with the chief eunuch to murder his oldest brother, the emperor’s presumed heir, and to seize the throne himself. 
 
 Now archaeologists have found tantalizing clues that the power grab was even more brutal than Sima Qian described. A group of skeletons was found with artifacts belonging to the royal family. These were mostly males, possibly the deceased emperor’s sons. One skull offers clues to their fate. It’s split by the metal bolt from a crossbow, likely shot at close range. Experts now believe these young princes may have been executed by their ambitious sibling who was trying to secure the throne for himself.

 In another area, very close to the emperor’s burial, archaeologists have identified a group of about a hundred tombs. But after excavating several, they’re still unsure of what they’ve found. The burial chambers are empty, and body parts lie strewn in the doorways along with a scattering of pearls and pieces of gold. Were these the royal concubines, buried near the deceased emperor to serve him in the next world as they had in this life? Or do these graves represent something sinister? 
 
 According to the account left by Sima Qian, the new emperor—the usurper—killed many of his father’s concubines. Sad as it may seem, that move would have made sense to someone whose claim to the throne was shaky. The usurper had already killed the heir apparent and also likely did away with other brothers who were potential rivals. But what if some of the concubines were pregnant? And what if one were to give birth to a boy who was then hidden, brought up in secret, trained to be a great warrior, and finally presented as a fully grown man able to overthrow his much older brother and take their father’s title and territories for himself? 
 
 In thinking through this worst-case scenario, there would have been no choice. The women had to die. But why their bodies were dismembered is unclear. Perhaps clues will turn up in the many burials that are still to be excavated.

 In the end, though, all the bloodshed was for naught. The usurper, Qin Er Shi, couldn’t begin to fill his father’s shoes. His rule lasted a mere three years, and his family’s dynasty was soon overthrown. The first emperor’s tomb surely holds many more surprises, but archaeologists have no plans to excavate it in the near future. Exposing fragile artifacts to air and light might damage them beyond repair, it’s feared, so the tomb will most likely stay buried until radically new conservation technologies are discovered in the future. 
 
 Sima Qian wrote that the emperor was laid to rest in a bronze coffin, and his burial chamber was filled with lavish grave goods—replicas of palaces, rivers of mercury, “rare utensils and wonderful objects.” But Sima Qian was writing more than a century after the first emperor’s death. Could he really have gotten all the details right? 
 
 Some of his statements seem too over the top to be true—that the emperor pressed 700,000 laborers and convicts into service to build his grand funerary landscape, for example. And Sima Qian seems to have skipped over some important features altogether, offering not one word about the creation of the terra-cotta army. 
 
 But in light of the evidence for royal murders before the unlikely succession of a very junior prince, it seems entirely possible that his description of the royal burial chamber is accurate—and that archaeologists will someday uncover Qin Shi Huang Di’s fabled trove of treasures. ||||| Image copyright Getty Images Image caption Greek artisans may have trained those who made the Terracotta Warriors 
 
 China and the West were in contact more than 1,500 years before European explorer Marco Polo arrived in China, new findings suggest. 
 
 Archaeologists say inspiration for the Terracotta Warriors, found at the Tomb of the First Emperor near today's Xian, may have come from Ancient Greece. 
 
 They also say ancient Greek artisans could have been training locals there in the Third Century BC. 
 
 Polo's 13th Century journey to China was the first to be well-documented. 
 
 However, Chinese historians recorded much earlier visits by people thought by some to have been emissaries from the Roman Empire during the Second and Third Centuries AD. 
 
 "We now have evidence that close contact existed between the First Emperor's China and the West before the formal opening of the Silk Road. This is far earlier than we formerly thought," said Senior Archaeologist Li Xiuzhen, from the Emperor Qin Shi Huang's Mausoleum Site Museum.

 Farmers first discovered the 8,000 terracotta figures buried less than a mile from the tomb of China's first emperor Qin Shi Huang in 1974. 
 
 However there was no tradition of building life-sized human statues in China before the tomb was created. Earlier statues were simple figurines about 20cm (7.9ins) in height. 
 
 To explain how such an enormous change in skill and style could have happened, Dr Xiuzhen believes that influences must have come from outside China. 
 
 "We now think the Terracotta Army, the Acrobats and the bronze sculptures found on site have been inspired by ancient Greek sculptures and art," she said. 
 
 Prof Lukas Nickel from the University of Vienna says statues of circus acrobats recently found at the First Emperor's tomb support this theory.

 He believes the First Emperor was influenced by the arrival of Greek statues in Central Asia in the century following Alexander the Great, who died in 323BC. 
 
 "I imagine that a Greek sculptor may have been at the site to train the locals," he said. 
 
 Other discoveries include new evidence that the First Emperor's tomb complex is much bigger than first thought and 200 times bigger than Egypt's Valley of the Kings. 
 
 They also include the mutilated remains of women, believed to have been high-ranking concubines of the First Emperor, and the skull of a man with a crossbow bolt embedded in it. 
 
 The skull is believed to have belonged to the First Emperor's eldest son, thought to have been killed along with others during a power struggle after the emperor's death.
– Marco Polo's travels to China in the 13th century are the first well documented record of a European reaching the empire. But archaeologists studying a famous trove of terracotta figures dug up in China now suggest that the first contact with the West occurred much earlier than thought—some 1,500 years before Polo's arrival, reports the BBC. Their theory is that those terracotta figures were inspired by Greek art, and that a Greek sculptor may have actually helped create them around 300 BC. For one thing, there's nothing in earlier Chinese art like these life-sized statues. “I imagine that a Greek sculptor may have been at the site to train the locals," says historian Lukas Nickel of the University of Vienna. But more than that, researchers have turned up European DNA from skeletons at a nearby site in northern China. The DNA find suggests Westerners were living there under the dynasty of Qin Shi Huang, the "First Emperor" who commissioned the so-called Terracotta Army for his tomb. "We now have evidence that close contact existed between the First Emperor’s China and the West before the formal opening of the Silk Road," says an archaeologist on the project. "This is far earlier than we formerly thought.” An ongoing study of the tomb has also revealed the remains of what could be the emperor's sons, reports National Geographic. Experts say the remains—including a skull pierced by a crossbow bolt—match an account of one of the emperor's sons murdering his brothers to seize control after his father's death in 210 BC.
