It is curious that, although possessing the crown for so long a term, and enjoying a more brilliant reign than any preceding monarch, he neither left behind him any inscriptions, nor any sculptured memorials.

The only material evidences that we possess of his reign are his coins, which are exceedingly numerous.

According to Mordtmann, they may be divided into three classes, corresponding to three periods in his life.

The earliest have on the reverse the fire-altar, with two priests, or guards, looking towards the altar, and with the flame rising from the altar in the usual way.

The head on the obverse is archaic in type, and very much resembles that of Sapor I.The crown has attached to it, in many cases, that "cheek-piece" which is otherwise confined to the first three monarchs of the line.
