This coin has an unusual representation of a captive...he is prone and being trampled by Sol. I think it might be a commemoration of Aurelian's victory over Vabalathus. The coin is from Antioch, which is the same mint that Vabalathus was striking coins. The new RIC site by Estiot dates these coins to A.D. 274- 275 and even describes the prone figure as wearing "oriental dress"
Surely this coin is a commemoration of the destruction of the rebellious Palymerene Empire, but just perhaps the prone figure represents Vabalathus.
