In the land of Persia, among the Persians whom Mithridates I. subjugated to the dominion of the Arsacids, reminiscences of the ancient time, of the splendour and glory of the Achæmenids, were naturally more lively than in Parthia, which was formerly subject to the Persians, and now under the Arasacids stood at the head of Iran. In Persia, Artakshatr (Ardeshir), the son of Papaki, the grandson of Sassan, rebelled against king Artabanus IV. In three great battles the Persians contended with the Parthians; the latter were conquered, and Artabanus fell, and with him the kingdom of the Arsacids after a continuance of 476 years (225 A.D.). With the reign of Ardeshir began a more energetic restoration of Iran. He and his successors after him revered the memory of the Achæmenids, and strove to continue their achievements[99]. We again hear of seven houses, and seven princes who had the right to wear diadems beside the king, like the seven tribal princes of the old Persian kingdom;[100] we find the fire-altar before the tent of the Sassanids as well as the Achæmenids; and in the army of the Sassanids, no less than in that of Darius and Xerxes, was a troop of "immortals." Ardeshir, like the founder of the Persian empire, caused a portrait of himself on horseback to be cut in a rock-wall to the north-west of Persepolis (Naksh-i-Rustem) in remembrance of the achievements which established his kingdom--the rock on which 700 years before Darius had marked his tomb by a portrait and inscription. The inscription under this portrait (in the Pehlevi of East and West Iran, with a Greek translation) runs thus: "Portrait of the worshipper of Mazda, the god Artakshatr (Artaxares in the Greek), the king of kings of the Arians (of the kings of Airan, in the Pehlevi texts), the scion of the sky (_minu chitri_), the son of the god Papaki, the king."[101] Ardeshir's son, Shapur I. (241-272 A.D.), caused his victory over Valerian and his capture of the emperor to be recorded on the same rock; we see Shapur on horseback, and Valerian kneeling before him, a representation which recurs at the old Persian city of Darabgerd. At Naksh-i-Rejeb, between the rock-wall of Naksh-i-Rustem and Mount Nachmed, on which abutted Persepolis, the proud citadel of the Achæmenids, and in the grotto of Haiyabad, we find in the one case a portrait of Shapur, and in the other inscriptions which mention this ruler and king Varahran. At Kermanshah, on the western side of Mount Behistun, on the eastern side of which mountain Darius inscribed the proudest memorial of his achievements, we see king Ardeshir, and beneath him the corpse of Artabanus; behind the king is Mithra with the club which gave him victory, and before him Auramazda who presents the ring of empire to Ardeshir. Not far from this portrait Shapur II. (309-379 A.D.) caused a grotto to be excavated in the rock. In the sculpture of this cave we see the goddess Anahita, who presents to the king the ring of empire; at some distance are the hunting expeditions of the king; a second grotto close to this exhibits the pictures of king Auharmazdi II., the father of Shapur II., and of Shapur III. his second successor.[102]
