Шапур I
This kind of hairstyle can be only seen on those rock reliefs of Shapur I that were carved after 260 AD and is, therefore, the most important criterion for the precise dating of the colossal statue of Shapur I. Due to the details of the hairstyle, G. Reza Garosi succeeded to date the colossal statue exactly in the second half of the sixties of third century AD.
