Another route may have led from Nineveh to Nisibis, thence through the Jebel Tur to Diarbekr, and from Diarbekr up the Western Tigris to Arghana, Kharput, Malatiyeh, and Asia Minor.

Assyrian remains have been found at various points along this latter line, while the former is almost certain to have connected the Assyrian with the Armenian capital.
Armenian productions would, however, reach Nineveh and the other great central cities mainly by the Tigris, down which they could easily have been floated from Tilleh.

or even from Diarbekr.

Similarly, Babylonian and Susianian productions, together with the commodities which either or both of those countries imported by sea, would find their way into Assyria up the courses of the two streams, which were navigated by vessels capable of stemming the force of the current, at least as high as Opis and Thapsacus.
We may now proceed to inquire what were the commodities which Assyria, either certainly or probably, imported by these various lines of land and water communication.

Those of which we seem to have some indication in the existing remains are gold, tin, ivory, lead, stones of various kinds, cedar-wood, pearls, and engraved seals.
Many articles in gold have been recovered at the various Assyrian sites where excavations have been made; and indications have been found of the employment of this precious metal in the ornamentation of palaces and of furniture.
