Centripetal settlement and segmentary social formation of the Banpo tradition

Creating a spatial environment to facilitate social operation is a common practice among human groups. Segmentary social formations have limited regulatory capacity due to the lack of formally sanctified authorities. The pressure is on the emergency of atternative mechanisms that regulate the practice of segmentary principles. The Neolithic site at Jiangzhai in North China is a classic archaeological example of using the centripetal plan and demarcated space to support the working of segmentary organization. The occupation was partitioned into three concentric divisions of the central plaza, residential and burial zones. The later two zones were further demarcated into spatially discrete areas for allocating the social segments comprising the community. The arrangement translated the abstract segmentary principles into tangible space where everyday practices played out. It created a spatiality that placed individual acts under the watch of the entire community, thus enabling the effective policing against deviated practices by public opinions. Analyses of the material remains distributed in the highly ordered built environment indicate that food sharing was practiced in the communal level, and craft production of the ceramics was likely organized in the household level. Patterns of monochrome paintings and etched signs on the ceramics suggest the sharing of symbolism in a pan-community network. The study also isolates the budding of non-conforming acts that would one day fracture the segmentary community.
