The research of the mythical and the religious traditions of the Paeonians in Early Antiquity, so far has been mostly directed towards gathering, analyzing and interpreting the written sources regarding this matter and towards their linking to the respective archaeological and linguistic material. The comparative studies have focused on comparing these traditions to the analogical phenomena within the Ancient Hellenic and the neighboring Balkan cultures. Contemporary research of myths and religion in the Ancient and Archaic cultures is not exhausted with this approach; moreover, it is deepened with new, mostly inter-disciplinary concepts which introduce methods of anthropology, ethnology, ethno-linguistics and especially semiology and analytical psychology. This paper is also dealing with such a research, in this case of the water, more precisely the river in the mythical and the religious traditions of the Paeonians.
