Gestion de l’incertitude dans une portion originale du paysage sacré gallo-romain: les sanctuaires des eaux

The study of water cults in Gaul suffers not only from a great deal of variability in the quality of the available data, which is a common issue in archaeology, but also, more specifically, from the burdening of past historiographical approaches, which contributed to conveying a distorted view of the phenomenon. Accordingly, our main problems lie in site identification and reliability assessment. Until recently this uncertainty was avoided by widening the study to all sites with at least one characteristic attribute, or conversely, by limiting the corpus to the best documented sites. It seemed necessary to develop tools that would exploit this uncertainty, to study the phenomenon in the most complete possible way. These tools take the form of a database, associated with a GIS, leading to the practical evaluation of a site potential using a calculation grid
