Towards the north, along the flanks of Mons Masius from Nisibis to the Euphrates, Strabo seems to place the Mygdonians, and to regard the country as Mygdonia.

Below Mygdonia, towards the west, he puts Anthemusia, which he extends as far as the Khabour river.

The region south of the Khabour and the Sinjar he seems to regard as inhabited entirely by Arabs.

Ptolemy has, in lieu of the Mygdonia of Strabo, a district which he calls Gauzanitis; and this name is on good grounds identified with the Gozan of Scripture, the true original probably of the "Mygdonia" of the Greeks.

Gozan appears to represent the whole of the upper country from which the longer affluents of the Khabour spring; while Halah, which is coupled with it in Scripture, and which Ptolemy calls Chalcitis, and makes border on Gauzanitis, may designate the tract upon the main stream, as it comes down from Ras-el-Ain.
