This project is the third and final continuation of two successful previous studies on Celtic divine names in Roman inscriptions from the Germanic provinces. The FWF project P 29274-G25 focused on the province of Germania Inferior, while project P 34422 G investigated the military zone in northern Germania Superior. The project is closely linked to the international research network F.E.R.C.AN., which aims to compile and analyse all Celtic divine names found in Roman inscriptions.

This project will build upon the findings of the previous studies by shifting the research focus to parts of Upper Germania which not only were formerly Celtic settlement areas, but firstly, had fewer documented soldiers and groups originating from the right bank of the Rhine compared to Lower Germania and the military zone of Upper Germania, and secondly, exhibit migration-related cultural influences from inner Gaul.

The extension to the province of Raetia closes the geographical gap to Noricum, which is particularly relevant as Raetia served as a contact zone for religious and cultural influences from the neighbouring Germanic and Noric regions. Additionally, Raetia is characterized by a cultural division, with Celtic-influenzed areas in the Alps and Raetian-dominated regions in the high mountains.
