Divinités conceptuelles et pouvoir dans le polythéisme romain

This paper discusses some aspects of the deities that bear the names of concepts. After discussing the problem of defining this kind of deities within the history of modern historiography, the article concentrates on three topics. The first is the competition and semantic struggle on the meanings of concepts ; the second are the fluid boundaries between deities, concepts, and personal attributes ; the third the connection between the Roman Empire and the diffusion of these deities.
