Matthew Canepa's recent study of the cultural and political interactions between Rome and Sasanian Iran, has provided an opportunity to reassess Sasanian rock reliefs in light of the claims and counter claims between these two empires. Since victory over Romans meant a victory over an-Erān, and generated the most potent of all farrs, i.e. the Aryan farr, many rock reliefs were conceived to show its reflection on the king. What is most interesting, though, is the array of nuances that are incorporated in them to account for the differences that were particular to each situation.
