The ruins of Khorsabad, Keremles, Nimrud, and Koyunjik bear on their bricks distinct local titles; and these titles are found attaching to distinct cities in the historical inscriptions.
Nimrud, as already observed, is Calah; and Khorsabad is Dur-Sargina, or "the city of Sargon." Keremles has also its own appellation Dur-* * *, "the city of the God [--]." Now the Assyrian writers do not consider these places to be parts of Nineveh, but speak of them as distinct and separate cities.

Calah for a long time is the capital, while Nineveh is mentioned as a provincial town.

Dur-Sargina is built by Sargon, not at Nineveh, but "near to Nineveh." Scripture, it must be remembered, similarly distinguishes Calah as a place separate from Nineveh, and so far from it that there was room for "a great city" between them.

And the geographers, while they give the name of Aturia or Assyria Proper to the country about the one town, call the region which surrounds the other by a distinct name, Calachene.

Again, when the country is closely examined, it is found, not only that there are no signs of any continuous town over the space included within the four sites of Nimrud, Keremles.
Khorsabad, and Koyunjik, nor any remains of walls or ditches connecting them, but that the four sites themselves are as carefully fortified on what, by the theory we are examining, would be the inside of the city as in other directions.
