Votive stele, 3rd century AD, with the representation of a ‘rider god’ .

More ‘rider god’ steles are at the Burdur Museum. Under the Roman Emperor Gordian III (238-244) the god on horseback appears on coins minted at Tlos, in neighboring Lycia, where he was named ‘Kakasbos’ from the early 4th century BC on.
A similar god appears in the Balkans too: there he is conventionally named the ‘Thracian horseman’. It is a recurring motif from the iconography of Paleo-Balkanic mythology during the Hellenistic and Roman era, also known as the ‘Heros Karabazmos’, a god of the underworld usually depicted on funeral statues as a horseman slaying a beast with a spear.
