Cultural exchange and technical artistry: Gold ornaments found in pre-imperial Qin Tomb at Ta’erpo, Shaanxi

Abstract

The current study investigates the use of precious metals, aesthetic taste, manufacturing techniques, and craftworking practices in the pre-imperial Qin period before the unification of China, focusing on an interdisciplinary study of gold ornaments discovered at the Ta’erpo cemetery in Xianyang, dating to the 4th-3rd centuries BCE. Employing multi-spectral analytical methods, including 3D Digital Microscopy (OM) and Scanning Electron Microscopy with Energy Dispersive X-Ray Spectroscopy (SEM-EDS), we conducted non-invasive analyses and technological study of a selection of gold artefacts. The results reveal the mastery of sophisticated techniques, including granulation and filigree, which were rarely seen in central China prior to the 2nd century BCE. These delicate decorative techniques required precision, skill and deep understanding of gold metalworking, which demonstrated a high level of technological competence among Qin craftsmen. The investigated ornaments were crafted from very pure gold with content reaching up to 99.62 wt% gold, a rarity among early Chinese gold artefacts. Examining pre-imperial Qin goldwork within a broader Eurasian context reveals that these innovative artistic styles and decorative techniques were originally intertwined with wider influences from the Hellenistic world and the central Asian steppes. This research enriches the understanding of ancient civilization's interconnectedness and the ability of local goldsmith to adapt and integrate foreign influences into their own artistic traditions.
