The Source of the Douix in Châtillon-sur-Seine, France, has been visited by local inhabitants for over 2000 years and served as a watery focal point for the ritual deposition of various types of offerings. While water deposits are by no means uncommon across Europe, the continued use of a single space over multiple millennia is. An examination of the preserved offerings at the Douix indicate there are three phases of depositional activity: late Hallstatt to early La Tène periods, late La Tène to Gallo-Roman periods, and the early modern period. Despite being separated by hundreds of years there are similarities across depositional phases including the importance of modified metallic objects, personal ornamentation, and possible connections to women. Could the persistence of these ritual practices be the result of behavioural and ideological continuities? If not, how can we interpret this complex record of intermittent deposition? We examine the deposits from each phase in their wider social and ritual contexts, including the Douix’s connection to the Hallstatt princely centre of Mont Lassois, Gallo-Roman ritual traditions, and the historic folklore surrounding springs. We then explore the inter-depositional phases and discuss the conditions that could lead to the persistence of ideas despite the dearth of material evidence and summarise what these patterns mean for the history of ritual activity at the Source of the Douix.
