3d models and the faces of Qin?

We're excited to have just had another paper come out (you can find it in the Journal of Archaeological Science here) that describes how we have been building 3d models of the terracotta warriors and using them not simply for nice documentation and presentation, but also to try to address some thorny analytical questions too. The 3d modelling technique itself is an extremely promising one (derived from the fascinating filed of 'computer vision') which is fast becoming popular in archaeology since it was first introduced a couple of years ago (our project can claim to be an early adopter, but the first archaeological application is probably this one). I'll come back to the technique itself below, but the background rationale for why we might find such models useful for the Imperial Logistics project is also interesting. More...

Our deliberately ambitious current project stage (2011-2016) will extend similar methods to consider the terracotta warriors themselves and look for cross-cutting organisational patterns between them and the weapons they were supposed to carry into battle. Typological analysis (e.g. based on the presence/absence of certain facial features, torso types, inscriptions etc.) and multivariate statistics (e.g. based on the measurement of standard features on the warriors) will be combined with chemical and microstructural analysis. The frequent inscriptions found on both the weapons and the warriors will be considered as a coherent body of evidence for the first time. Moreover, a balanced approach to the warriors and their weapons will also now allow us to model their spatial patterns both individually and jointly, with a view to their implications with respect to two crucial aspects of early Chinese imperialism: military tactics and craft organisation.

Reaching beyond the mausoleum, we will use trace elements and lead isotopes to investigate whether the supply of clays and metals was centralised or also distributed in various units and different resource landscapes. Research will expand progressively to incorporate other structures within the mausoleum and a broader imperial resource landscape, retaining throughout the close coupling of artefact-based, spatial analysis and materials science perspectives that has so far proved so enlightening.
