Moya Catherine Carey uses a silver-gilt plate (Sasanian period) Iran Bastan Museum 1275, Tehran (http://warfare.ml/6-10/Sassanid-Plate-Bastan-1275.htm), for the typical costume on Sasanian royal hunting plates:

It has the king sitting backwards on the horse. This is unusual as other Sassanid and post Sassanid plates have figures making Parthian shots mounted normally. For example:

Did they ride facing backwards? Is Iran Bastan Museum 1275 plate indeed Sasanian? Does it have a better dating?

Curious. I wonder if it was a joke? Or perhaps a drunk silversmith?
Perhaps it's one of those incidents that needed to be celebrated in art!
Or maybe the artist was working from instructions and got it wrong (the noble king, facing backwards....)
