Fingerprints Reveal Women and Children Helped Build China's Terracotta Army
Analysis of ancient fingerprints suggests a more diverse workforce than previously assumed for the Qin Dynasty funerary monument.
New analysis of fingerprints discovered on the Terracotta Army suggests that women and children played a significant role in crafting the life-size figures, challenging previous assumptions that large-scale construction projects in ancient China relied solely on adult male laborers.
The study, published in the Journal of Cultural Heritage, examined 79 fingerprints found on 36 warriors. Researchers found that only 45 percent of the prints belonged to adult men. Adult women accounted for nearly 33 percent, while children under 15 years old left approximately 22 percent of the analyzed marks.
Scientists used a statistical analysis method called a Bayesian mixture model to measure the distance between fingerprint ridges. This distance increases with age and differs between genders, allowing researchers to differentiate between adult men, adult women, and children.
The Terracotta Army was commissioned by Emperor Qin Shihuang, the first emperor of China, in the early third century BC as part of his vast funeral complex. The army, intended to guard the emperor in the afterlife, consists of over 8,000 soldiers, 130 chariots, 520 horses, and 150 cavalrymen spread across three pits. The construction effort, believed to have spanned more than a decade, would have required a substantial workforce of sculptors, painters, and kiln operators.
Previous research had distinguished between warriors made by 'royal' potters and local potters, but little was known about the identity of the artisans themselves. The new findings suggest that the workforce was more diverse, with men and women working together, and adult artisans collaborating with younger helpers or apprentices.
Researchers acknowledge that the study has limitations, including a small sample size taken from a single area within the extensive mausoleum complex. They propose that future work should expand fingerprint sampling to other pits and workshops to investigate potential spatial and temporal variations in the workforce structure.
