兵马俑

In March 1974, farmers digging a well during a drought in Lintong county, east of 西安 Xi'an in Shaanxi province, struck something hard in the earth: broken terracotta, then a clay human head. They had cut into the edge of one of the great pits of the 兵马俑. Archaeologists who came to investigate found that the field sat above an underground chamber filled with row upon row of life-sized clay warriors, and that this pit was only the first of several.

The scale of what they had stumbled on was almost unbelievable. The first pit alone, the largest, eventually proved to contain something on the order of six thousand figures arranged in battle formation, in long corridors that had once been roofed with timber and matting. Two more major pits were soon found nearby, holding cavalry, chariots, and a command group of high officers. The find was wholly accidental; no clear, detailed record of this army had survived from antiquity, and its sudden emergence from a farmer's well rank it among the most dramatic archaeological events in history.

The army was built for 秦始皇 Qin Shi Huang, the First Emperor, the ruler of 秦 Qin who in 221 BCE conquered the last of the warring states and unified China for the first time, then gave himself the new title 皇帝 (huángdì, emperor) to mark that no previous king had ever held such power. He standardised the script, the currency, the laws, and the axle-widths of carts across his vast new realm, and he connected the northern frontier defences into the first version of the 长城 Great Wall.

He was also consumed by a fear of death and a desire to live forever. He sent expeditions in search of elixirs of immortality and the legendary isles of the immortals; he is said to have died, in 210 BCE, after taking mercury pills meant to prolong his life. Failing to escape death, he prepared for it on the same colossal scale as everything else he did. According to the 史记, construction of his tomb complex employed hundreds of thousands of labourers over decades. The terracotta army was the guard for that tomb, a complete military force modelled in clay so that the emperor would command real protection in the world beyond.

The army marks a turn in Chinese funerary practice. In earlier ages, powerful men were sometimes buried with living attendants, sacrificed to serve them in death. The substitution of sculpted figures, 俑 yǒng, for living victims was already a humane shift that Confucius's age had moved toward, and the First Emperor's clay legions are its most spectacular expression: an entire army that died with no one.

The figures are not a random crowd but a real army drawn up for war, and the three main pits divide it by function. Pit One, the great hall, holds the main body of infantry: long columns of armoured footsoldiers and a vanguard of unarmoured archers, the formation a Qin general would actually have deployed. Pit Two contains the more specialised forces, cavalrymen with their horses, kneeling and standing crossbowmen, and war chariots. Pit Three, the smallest, is the command post, with a chariot and a cluster of senior officers, the headquarters that directs the whole.

The soldiers were equipped with real bronze weapons, swords, spears, crossbow triggers, and thousands of arrowheads, many of them found remarkably sharp and uncorroded, evidence of sophisticated Qin metallurgy. The figures stand at full human height, the officers slightly taller than the rank and file in a deliberate hierarchy of scale. Rank is also legible in armour, headgear, and posture, so that the whole assembly reads as a precise model of the Qin military machine that had just conquered China.

The most haunting feature of the army is that the faces are individual. 千人千面, "a thousand people, a thousand faces": no two warriors are exactly alike. Yet they were not each sculpted from scratch. The figures were produced by an early form of assembly-line craft, with bodies, legs, arms, and heads made separately from moulds and then joined, after which artisans worked over each face and head by hand, adding the ears, hair, moustaches, and expressions that made every soldier distinct. It is mass production and individual portraiture at once, an industrial method in the service of a personal effect.

The warriors were also originally painted in vivid colour, reds, greens, purples, and blues over flesh-toned skin, so that the buried army would once have blazed with life. Tragically, the lacquer ground beneath the pigment dries and curls within minutes of exposure to modern air, and much of the paint flaked off as the figures were excavated. Conservators now work to stabilise colour on newly uncovered figures, and the search for ways to preserve it is one reason large parts of the site remain deliberately unexcavated.

The terracotta army, astonishing as it is, is only an outwork. It stands guard roughly a kilometre and a half east of the actual tomb of the First Emperor, a huge earthen mound that has never been excavated. The 史记 describes the tomb's interior in famous terms: a vast underground palace with a ceiling of pearls for stars, rivers and seas of flowing mercury, automatic crossbows set to kill intruders, and treasures beyond counting. Modern soil surveys have found genuinely anomalous concentrations of mercury in the mound, lending eerie support to the ancient account.

Chinese authorities have chosen not to open the central tomb, both out of respect and because current technology cannot guarantee the preservation of whatever lies inside, as the fading of the warriors' paint warns. So the heart of the First Emperor's necropolis remains sealed, its contents known only from Sima Qian's description and a scatter of survey data. The buried army outside it has become world-famous; the man it was made to guard still lies unseen beneath his hill.

Named a UNESCO World Heritage Site in 1987, the 兵马俑 is among the most visited sights in China and one of the best-known images of Chinese civilisation anywhere in the world. It has toured in major museums across the globe and become a fixed symbol of the country, ranked in popular sentiment as an eighth wonder of the world.

Its value is not only its spectacle. The army is a primary historical document of the Qin state at the moment of unification: its military organisation, its weapons technology, its dress, its administrative reach, and its capacity to mobilise labour on a scale that matches the building of the Great Wall. It confirms and enriches the written record of the 史记, turning the First Emperor from a figure of legend into a ruler whose actual soldiers we can stand before. Few archaeological finds anywhere have so vividly recovered a vanished world, a silent army still standing in formation more than two thousand years after the empire that made it fell.
