The coins of Artaxerxes present five different types. [PLATE XI., Fig. 1.] In the earliest his effigy appears on the obverse, front-faced, with the simple legend AETaHsnaTE (Artaxerxes), or sometimes with the longer one, BaGi ARTaiiSHaTR MaLKA, “Divine Artaxerxes, King;” while the reverse bears the profile of his father, Papak, looking to the left, with the legend BaGi PAPaKi MaLKA, “Divine Papak, King;” or BaBl BaGi PAPaKi MaLKA, “Son of Divine Papak, King.” Both heads wear the ordinary Parthian diadem and tiara; and the head of Artaxerxes much resembles that of Volagases V., one of the later Parthian kings. The coins of the next period have a head on one side only. This is in profile, looking to the right, and bears a highly ornamental tiara, exactly like that of Mithridates I. of Parthia, the great conqueror. It is usually accompanied by the legend MaZDiSN BaGi ARTaHSHaTR MaLKA (or MaLKAN MaLKA) aiean, i.e. “The Ormazd-worshipping Divine Artaxerxes, King of Iran,” or “King of the Kings of Iran.” The reverse of these coins bears a fire-altar, with the legend ARTaHSHaTR nuvazi, a phrase of doubtful import. In the third period, while the reverse remains unchanged, on the obverse the Parthian costume is entirely given up; and the king takes, instead of the Parthian tiara, a low cap surmounted by the inflated ball, which thenceforth becomes the almost universal badge of a Sassanian monarch. The legend is now longer, being commonly MaZDiSN BaGi ARTaiisi-iaTR MaLKAN MaLKA airanMiNUCHiTRi iniN YazDAN, or “The Ormazd-worshipping Divine Artaxerxes, King of the Kings of Iran, heaven-descended of (the race of) the Gods.” The fourth period is marked by the assumption of the mural crown, which in the sculptures of Artaxerxes is given only to Ormazd, but which was afterwards adopted by Sapor I. and many later kings, in combination with the ball, as their usual head-dress. The legend on these coins remains as in the third period, and the reverse is likewise unchanged. Finally, there are a few coins of Artaxerxes, belonging to the very close of his reign, where he is represented with the tiara of the third period, looking to the right; while in front of him, and looking towards him, is another profile, that of a boy, in whom numismatists recognize his eldest son and successor, Sapor.
