The Terracotta Army

For a short while after a warrior comes out of the ground, you can see him as he was meant to be seen. There is red on the robe, green on the trousers, a face with skin tone on it, whites in the eyes. Then the air gets to him. The lacquer underneath the paint, kept soft for twenty centuries by damp soil, starts to dry. As it dries it curls, and as it curls it lifts the pigment off in flakes. This is not a slow process measured in seasons. It happens in minutes, and in the earliest digs it happened before anyone could photograph it properly.

That is why the excavation is deliberately slow now. Newly exposed surfaces are kept wet, wrapped, and treated with consolidants that soak into the lacquer layer before it can move. The gray army everyone pictures is not the army that was made. It is what is left after contact with the twentieth century.

An Industry With One Customer

The figures belong to the burial complex of Qin Shi Huang, the ruler who ended several centuries of warring states and put China under a single administration for the first time. Work on the tomb began while he was still a boy newly seated on the Qin throne and continued for decades, expanding enormously after unification, with labor conscripted from across the empire.

The army was buried east of the tomb in enormous trenches: brick floors, rammed-earth walls dividing the corridors, heavy timber beams overhead, then matting, then earth. Nothing about it was designed to be looked at. The moment it was finished it was covered up.

The only way to make this many figures was to industrialize. Legs were built solid, torsos were coiled hollow from thick strips of clay, and arms, hands and heads were produced separately and attached. A handful of basic molds supplied the heads, and then each face was finished by hand with added clay: brows, moustache, ears, the knot of hair, the fold of a collar. No two come out the same. That does not mean each soldier is a portrait of a real man, and there is no evidence that it is. It means the workshop was designed to get an almost unlimited number of faces out of a limited number of parts.

Rank is legible at a glance. Kneeling archers, standing crossbowmen, charioteers, officers in heavier armor with more elaborate headgear, chariot horses and cavalry horses. Nobody can give a firm total; the estimates run into the thousands and shift as more of the trenches are opened.

Then there are the marks. A great many figures carry a name stamped or incised into them, usually somewhere nobody would look, naming the foreman or the workshop responsible for that piece. Dozens of names have been read. This was not signing a work of art. It was accountability: if the piece failed, the record of who to blame was baked into it.

Burned, Looted, Ploughed Over

The emperor died in 210 BC while travelling in the east of his empire. The order he built barely outlived him. Within a few years the dynasty had collapsed into civil war, and the pits record what came next. The roof timbers were burned. The roof came down. Most of the figures were smashed under the weight of the earth above them. The bronze weapons the soldiers had been holding are largely missing, which means someone came through and collected them. Who set the fire is still argued about.

Then two thousand years of farming on top. In 1974 a group of men digging a well in a field roughly thirty kilometres east of Xi'an hit something hard a few metres down. What they pulled out looked like broken pottery, only far too thick, and then came a shoulder, and then a life-size head. Word travelled to the county, then to the museum, and within a year the field had become an excavation with rows of soldiers standing in formation under it.

The Mercury Question

One more strange detail. Sima Qian, writing his Shiji about a century after the fact, describes the inside of the tomb in some detail: rivers of mercury made to flow by machinery, the heavens rendered on the ceiling, crossbows rigged to fire at anyone who broke in. The same text says nothing at all about a clay army. For a long time the mercury was treated as literary decoration, until soil sampling on the burial mound came back with mercury readings well above the surrounding background. That does not confirm the rest of the account, but it makes coincidence a harder answer.

Now

The site went onto the UNESCO World Heritage list in 1987 and is displayed in place, under large halls built over the trenches. Pit one is still being excavated in sections; every figure that comes out goes to a conservation workshop to be rebuilt from fragments. Humidity and temperature are monitored constantly, and mould is the most immediate daily threat.

The burial mound itself has never been opened. The reason is not mystery but restraint: a team that has watched color evaporate in minutes knows exactly what opening a sealed chamber can cost. Above ground, two thousand years of dynasties and borders came and went. Below it, nothing has moved.
