The tattoos of the Pazyryk ice mummies are of paramount importance for the archaeology of Iron Age Siberia and are often discussed from a broad stylistic and symbolic perspective. However, deeper investigations into this cultural practice were hindered by the inaccessibility of quality data. Here, the authors use high-resolution, near-infrared data in conjunction with experimental evidence to re-examine the tools and techniques employed in Early Iron Age tattooing. The high-quality data allow for the previously unfeasible distinction of artist hands and enable us to put the individual back into the picture of a widespread but rarely preserved prehistoric practice.
