Outline of Final Research Achievements

This study attempts to understand and elucidate the foundations for constructing a methodology to recover the “dynamic” and specific body techniques of ancient potters from the “static” traces of pottery. Three-dimensional measurements and analyses of corresponding body movements were conducted on modern pottery (ethnographic material) in good condition, for which the potters and production movements are known. Through detailed observation of both the high-density 3D models and the actual objects, the relationship between body movements and traces was examined in terms of patterns of traces within and among individual potters, similarities and differences in body movements, variability and stability of techniques, etc., and fundamental indicators were obtained that contribute to understanding the relationship between pottery, tools, and movements.

Academic Significance and Societal Importance of the Research Achievements

本研究では，製作者が既知である現代土器を対象に三次元計測と動作解析を行い，製作痕と身体動作の対応関係について，詳細観察や定量的分析から過去の身体技法を解読するための基礎的指標を得ることができた。また，土器資料から製作者個人や熟練度等を把握するための指標も得られた。以上から，土器研究の焦点が痕跡を基にした「静的」な検討から，製作者の動作を含む「動的」な検討へ移行することの重要性が確認できた。過去の文化・社会の復元に迫る理論構築や，人と道具・動作に関する認知考古学的課題にも貢献できる成果であると考える。
