The Medes are represented by him as capturing Babylon at this time, and imposing themselves as rulers upon the country.

Eight kings reigned in space of 234 (or 224) years, after which we hear no more of Medes, the sovereignty being (as it would seem) recovered by the natives.

The coincidences of the conquest the date, the foreign sovereignty and the name Zoroaster, tend to identify the Median dynasty of Berosus with a period of Susianian supremacy, which the monuments show to have been established it Chaldaea at a date not long subsequent to the reigns of Urukh and Ilgi, and to have lasted for a considerable period.
There are five monarchs known to us who may be assigned to this dynasty.
The first is the Kudur-Nakhunta above named, who conquered Babylonia and established his influence there, but continued to hold his court at Susa, governing his conquest probably by means of a viceroy or tributary king.
Next to him, at no great interval, may be placed Kudur-Lagamer, the Chedor-laomer of Scripture, who held a similar position to Kudur-Nakhunta, reigning himself in Elam, while his vassals, Amraphel, Arioch, and Tidal (or Turgal) held the governments respectfully of Shinar (or Upper Babylonia), Ellasar (Lower Babylonia or Chaldaea), and the Goim or the nomadic races.

Possessing thus an authority over the whole of the alluvial plain, and being able to collect together a formidable army, Kudur-Lagamer resolved on a expedition up the Euphrates, with the object of extending his dominion to the Mediterranean Sea and to the borders of Egypt.

At first his endeavors were successful.
