This volume presents the proceedings of Session XXVIII-4 of the XVIII UISPP World Congress (4-9 June 2018, Paris, France), Characterization, Continuities and Discontinuities of Graphic Manifestations of Prehistoric Societies. Papers address the question of exchange and mobility in prehistoric societies in relation to the evolution of their environments through the prism of their graphic productions, on objects or on walls. This volume offers the opportunity to question their symbolic behaviours within very diverse temporal, chrono-cultural or geographic contexts. It also provides the framework for a discussion on cultural identity and how this was asserted in the face of environmental or social changes or constraints. This volume offers the opportunity to question their symbolic behaviors, within very diverse temporal, chrono-cultural or geographical contexts. It also offers the framework for a discussion on cultural identity and the way in which they affirmed it, in the face of environmental or social changes or constraints. Decorated Magdalenian spear throwers, or ivory objects from the Gravettian, bear witness in turn to technical or symbolic permanences, and at the same time to local singularities on a European scale. The notion of cultural identity is approached through the singular production of portable art from the Taillis des Ĉoteaux, or the theme, rare but not secondary, of the feline in parietal and portable art, illustrating often tenuous boundaries between functional and symbolic spheres. Finally, the relationship between art and its environment is expressed in more recent but equally remarkable rock territories, the Paris Basin in the Mesolithic, and predynastic Egypt. The articles in this session show how systems of thought expressed by images can thus persist over a long period of time, and bear witness to elaborate social practices, the rhythms of which are not always in line with the material productions of everyday life.
