Its later name was Rai; the ruins (near the modern Teheran) are said to cover the land for leagues. Besides Ragha there were at one time numerous flourishing cities in Raghiana.[458] Campadene,[459] the Campada of the inscriptions of Darius, we must look for in the south of Media, to the east of the Zagrus; it is no doubt the district now called Chamabatan.[460] According to the statement of the Greeks, the district of Bagistana extended to a mountain which was sacred to Zeus. As Diodorus says, it was a region fit for the gods, filled with fruit-trees and every other kind that ministers to delight and enjoyment.[461] The name of the mountain consecrated to Zeus, Bagistana, and the similar name of the district, go back to the title under which the gods are comprised in the Avesta and the inscriptions of Darius (Old Bactr. _bagha_, Old Pers. _baga_, New Pers. _bag_); and if Diodorus tells us that the region was a land fit for the gods, the name Bagistana means the abode of the gods. The district may have been held peculiarly sacred by the Medes, or the name may have been intended to express their gratitude for its fertility and beauty. We can fix precisely the position of this district by the hill consecrated to Zeus near the modern Behistun. It lies south-west of Elvend, between that mountain and the Zagrus in the valley of the Choaspes, and is the district now known as Kirmenshah. According to the statements of Berosus, the historian of Babylon, the Medes in the most ancient period had already reigned over Babylonia for more than two centuries. They had suddenly collected an army, reduced Babylonia, and there set up tyrants of their own people. According to the succession of the dynasties which Berosus represents as ruling over Babylonia, the beginning of this supremacy of the Medes fell, as has been shown (I. 241, 247), in the year 2458 B.C. The first of the Medes who thus ruled in Babylon is called Zoroaster by Syncellus, after Polyhistor; according to this writer the seven Medes reign till the year 2224 B.C. Whether Berosus called the first Median king who reigned in Babylon Zoroaster, or Polyhistor has ascribed that position to him as the most famous name in Iran, or the only name known in antiquity, must be left undecided, no less than the actual fact of the Median supremacy.
