Abstract
To conclude the lecture series, we will explore the perceptions and concepts developed by the ancient Mesopotamians themselves to account for the complex relationships between societies and environments. In particular, we will focus on the motif of the universal Flood, at the heart of Mesopotamian historical perception. Adopting what is known in anthropology as a " emic "perspective, we will seek, at the crossroads of cultural history and the history of mentalities, to show how even myths have a history, and how they reflect in part the social and/or environmental anxieties of their authors.
