consists of two large plains separated from each other by the Karachok
hills. In this way Arbelitis, the plain between the Karachok and Zagros,
would fall within Adiabene, but it is sometimes made a distinct region,
in which case Adiabene must be restricted to the flat between the two
Zabs, the Tigris, and the harachok. Chalonitis and Apolloniatis, which
Strabo seems to place between these northern plains and Susiana, must be
regarded as dividing between them the country south of the Lesser Zab,
Apolloniatis (so called from its Greek capital, Apollonia) lying along
the Tigris, and Chalonitis along the mountains from the pass of Derbend
to Gilan. Chalonitis seems to have taken its name from a capital city
called Chala, which lay on the great route connecting Babylon with the
southern Ecbatana, and in later times was known as Holwan. Below
Apolloniatis, and (like that district) skirting the Tigris, was
Sittacene, (so named from its capital, Sittace which is commonly
reckoned to Assyria, but seems more properly regarded as Susianian
territory.) Such are the chief divisions of Assyria east of the Tigris.

West of the Tigris, the name Mesopotamia is commonly used, like the
Aram-Naharaim of the Hebrews, for the whole country between the two
great rivers. Here are again several districts, of which little is
known, as Acabene, Tigene, and Ancobaritis. 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
