This paper presents a new dedication to Potamos found in the village of Parsibey (Province Eskişehir) in 2018. The inscription on a white marble column mentions the names of Phoinix (without patronymic) as dedicator and his son Hermes. The dedication of Phonix is the second known columnar votive offering to the river-god from the same village. It provides new evidence for the cult of Potamos in Northeast Phrygia and supports the suggestions for the lo- cation of the sanctuary of the river-god, which should be looked for near Parsibey. Further ded- ications to Potamos found in the region indicate that the river-god was recognised by the inhab- itants as Tembris, the main river in Northeast Phrygia. Two votive stelai from the region, transported to Istanbul and Iznik, give a depiction of the river god as an old man with a beard.
