The identity of the warrior god portrayed on the reverses of Roman provincial coins of Ariassos in Pisidia is open to debate. He could be the god Ares or the warrior-hero Solymos since the iconography of their depictions on coins is similar. Ancient sources confirm the existence of both cults in Pisidia. Some archaeological evidence also suggests that there is a temple of the deity in Ariassos, as a Pisidian shield occurs on the lintel of this building. The aim of this study is to compare the iconography of the warrior-god or warrior-hero depictions on the coins of Ariassos with similar images on coins of the other cities in the same region and neighbouring regions, and to confirm the identity of the god, supporting our conclusions with archaeological data.
