Within the framework of a PhD research project which is part of the Pondera Online collaborative project, I analyse the weights from several city-states in Western Asia Minor within three geographical areas: Propontis, Troas and Aeolis. For the first time this material will be studied from a global perspective. The poster presents the corpora of to date c. 600 weights and develops four complementary approaches: the typology of these weights (iconography, legend, metals, etc.), their metrology (reconstitution of the metrological structures of the city-states), their archaeological context, and anthropological value (their use in daily life). We will carry out local, regional and interregional analyses.
