After this victory Ardashir sent a challenge to Artabanus himself; their armies met by appointment in the plain of Hormizdjan, and Artabanus fell (the 28th of April, 227 A.D.). Ctesiphon and Babylonia must have fallen not much later, though Volagases V seems to have re-established himself there on his brother’s death, and a tetradrachm shows that he held the city till autumn 227 A.D. The conquest of Assyria and great part of Media and Parthia is assigned by Dion expressly or by implication to the year 228 A.D. And so the Parthian Empire was at an end.[c] FOOTNOTES [29] [Persia, or rather Persis, is the latinised form of a name which originally and exclusively designated only the country bounded on the north by Media and on the northwest by Susiana, which of old had its capital at Persepolis or Istakhr, and for almost twelve centuries since has had it at Shiraz.] [Illustration] [Illustration] CHAPTER II. THE EMPIRE OF THE SASSANIDS [Sidenote: [228-652 A.D.]] Of the countries whose sovereigns were subject to the dominion (sometimes actual and sometimes merely nominal) of the Parthian “king of kings,” Persia proper itself was one. The names of some of the lesser kings of that country during the Arsacid period are known to us, partly through a reference here and there in literature, partly from their coins; but we do not know whether they all belong to one and the same dynasty. About the beginning of the third century after Christ, the country presented a scene of confusion. The power of the local kings had fallen very low, and the mountainous regions, cleft asunder by natural divisions, were full of petty tyrants. Papak or Pabak, a son or descendant of Sassan, was one of these. He came originally from the village of Khir on the southern shore of the great salt lake east of Shiraz, and succeeded in overthrowing the last prince of that dynasty, Gozihr by name, in whose service he had been, and gaining dominion first over the district of Istakhr, the ancient Persepolis. On coins and inscriptions his son gives him the title of king. According to tradition, which in this instance is certainly trustworthy, his lawful successor would have been his son Sapor, to whom the Arsacid king is said to have granted the crown at his father’s request during the life-time of the latter.
