Terracotta Army and the Mausoleum of the First Qin Emperor (China)

Q: What is the conventional archaeological date of Terracotta Army and the Mausoleum of the First Qin Emperor (China), and what alternative dates have been proposed?

Conventional date: UNESCO says the tomb of Qin Shihuang, China's first emperor, was begun in 246 BCE. Citing the historian Sima Qian, it says work went on until the emperor died in 210 BCE. Alternative proposals: Open question: Quinn and colleagues (2017): Who made them? After decades of study, the 2017 team says much is still unknown: how the figures were made, where, and by whom. They read their results as a sign of a highly organized system of labor and skilled crafts. Who the workers were is not settled in the sources on this page. Interpretation: Li and colleagues (2014): Organized production: The trigger team sees evidence for large-scale, highly organized production. They say it matches what is known for the bronze arrows and what has been proposed for the clay figures.

Q: What has been measured at Terracotta Army and the Mausoleum of the First Qin Emperor (China) in peer-reviewed studies?

A huge burial complex: UNESCO says the grave mound still stands 51.3 m tall. Nearly 200 pits hold thousands of life-size clay soldiers and horses, plus bronze chariots and weapons. In all there are over 600 sites across 56.25 square km. Made near the site: A 2017 study looked at the statues' clay under a microscope. It compared the raw clay and clay recipes with other pottery from the tomb. The authors say this "proves that the terracotta warriors were made near the site." Clay from one place: The same team found links in makeup, method and location between objects. They suggest clay was prepared in one place and then sent out to different local workshops. Weapons made in batches: Bronze triggers are all that is left of the soldiers' crossbows. A 2014 study measured the triggers and mapped where they were found. They were made in batches, possibly stored, and later sent to groups of crossbowmen in Pit 1. Painted officer figures: A 2026 study tested twelve painted officer figures from Pit K0006. The paint sits on a lacquer base, with mineral colors such as cinnabar and malachite. The clay was fired at about 975–1081 °C. The authors say the figures "follow standardized Qin production protocols." The Terracotta Army guards the tomb of Qin Shihuang, the first emperor to unite China, in the 3rd century BCE. Thousands of life-size clay soldiers and horses stand in pits near the tomb. Studies of the clay, the paint and the bronze weapons ask how such a huge job was organized.
