Shapes of the statuettes differ according to many parameters, they may vary according to the sites of origin, the author of the works and they might reflect local influences of the workshops from which they originate. In this paper, we describe methods used to quantify and compare the shapes of the figurines and interpret results obtained by using such methods on a set of three-dimensional virtual objects. we show the results of these methods applied to a set of three dimensional virtual objects based on homologous points (landmarks) systematically defined and placed on the virtual models of mother goddess and Venus figurines. We use geometric morphometrics, including essentially generalized Procrustes analysis, to measure and display the differences in shapes and characterize the provenance of the Gallo-Roman figurines. Various analyses including chemical methods have been already carried out to determine the provenance of the statuettes and provide a basis for the comparison of our results. According to the results of the statistical analysis we assess the advantages and limitations of geometric morphometrics for the characterization of the provenance of the white clay figurines. Finally, from a broader perspective, we comment the interpretation of morphometrical analyses applied to archaeological objects.Categories and Subject Descriptors (according to ACM CCS): I.3.5 [Computer Graphics]: Computational Geometry and Object Modeling-Geometric algorithms, languages, and systems
