Pastoral Workshops? Rethinking Iron Age bone production in the Eastern Tianshan region
The concept of “workshop” is widely used in studies of ancient craft production, yet it often relies on rigid, culturally specific criteria that are ill-suited to mobile pastoral contexts, where conventional traces of organized manufacturing activity are seldom preserved. In Northern China, interpretations have been further shaped by a perceived divide between pastoralist and agricultural communities—the former assumed to rely on domestic product…
