Qin structural timbers and the First Emperor’s Mausoleum (Xi’an, China)

Anthracological studies of preserved wooden building materials can help reveal ancient networks of resource mobilisation. Here, the authors report on the analysis of 657 charred timbers from four ancillary pits at the UNESCO World Heritage Site of the Mausoleum of the First Qin Emperor. The frequent use of dark coniferous wood (fir, spruce and hemlock) indicates sophisticated logistical planning and labour organisation—matching historic records of Qin administrative ascendency—because these species required sourcing from across many kilometres of rugged terrain. Identification of a temporal shift towards the use of higher-elevation species points to the ecological impact of large-scale timber harvesting.
