The present paper deals with the dedications made by the soldiers from Germania Inferior to Celtic deities. The most frequently worshipped deities by soldiers of all ranks are Hercules Magusanus and Rhenus. Differences in the preference of Celtic to Germanic or Mediterranean divine names cannot be postulated. Since most of the inscriptions can be dated to the end of the 2nd or the 1st half of the 3rd century CE, it is not possible to speak of a Celtic worship of gods of any kind.
