Media is bounded on the east by Parthia, and by the mountains of the Cossæi, a predatory tribe. They once furnished the Elymæi, whose allies they were in the war against the Susii and Babylonians, with 13,000 archers. Nearchus says that there were four robber tribes; the Mardi, who were contiguous to the Persians; the Uxii and Elymæi, who were on the borders of the Persians and Susii; and the Cossæi, on those of the Medes; that all of them exacted tribute from the kings; that the Cossæi received presents, when the king, having passed his summer at Ecbatana went down to Babylonia; that Alexander attacked them in the winter time, and repressed their excessive insolence. Media is bounded on the east by these nations, and by the Parætaceni, who are contiguous to the Persians, and are mountaineers, and robbers; on the north by the Cadusii, who live above the Hyrcanian Sea, and by other nations, whom we have just enumerated; on the south by the Apolloniatis, which the ancients called Sitacene, and by the Zagrus, along which lies Massabatica, which belongs to Media, but according to others, to Elymæa; on the west by the Atropatii, and by some tribes of the Armenians.

There are also Grecian cities in Media, founded by Macedonians, as Laodiceia, Apameia, Heracleia near Rhagæ, and Rhaga itself, founded by Nicator, who called it Europus, and the Parthians Arsacia, situated about 500 stadia to the south of the Caspian Gates, according to Apollodorus of Artemita.
