China and the steppe: technological study of precious metalwork from Xigoupan Tomb 2 (4th–3rd c. BCE) in the Ordos region, Inner Mongolia
Abstract
Abstract Technology employed by the ancient goldsmiths is traceable through archaeometallurgy. Using non-destructive analytical methods, namely, a 3D digital microscopy and a scanning electron microscopy with energy dispersive spectrometer (SEM–EDS), we investigated the manufacturing techniques and chemical composition of gold and silver artefacts recovered from Tomb 2 (M2), the richest find from Xigoupan cemetery (fourth-third century BCE) in the northern part of Jungar Banner, Inner Mongolia. The present research contributes to a better understanding of the inventive nature of precious metal working industry in early China (eighth-third century BCE). First, cultural interchange was evidenced in the metalwork examined, notably as being closely linked to techniques emerging from the Eurasian steppes. In Xigoupan M2, the ornamentation of sheet works in the Scytho-Siberian animal style was seen to be clearly influenced by the central Asian steppe goldsmithing practice, while certain cast items were typical of the Chinese tradition. Second, our analysis reveals that the gold appliqués with raised animal figures that were previously thought to be repoussé work have actually been made with double-sided carving. We consider such a new technology as one of local inventions that was inspired by methods arriving from the central Asian steppes. In addition, our analysis of elemental composition reveals that the gold artefacts found in Xigoupan M2 to be made of natural gold, while the horse harness ornament is made of pure silver. These results, combined with the study of the existing data pertaining to comparable examples, attest to the shared craftsmanship in prestige metal production across the northern Chinese states, especially with regard to the pre-imperial period Qin workshop.
