When next we hear of a king of Urardhu we are able to recognise in his name the earliest of the rulers who appear in the Vannic texts. And this monarch, Sarduris the First, the contemporary of the same Shalmaneser and his antagonist about 833 B.C., was the founder of the fortress of Van. No better position for a stronghold against a Power operating from the lowlands in the south could have been discovered by the builders of an empire on the Armenian plains. In the later phases of the history of Armenia the movements of empires and peoples have generally proceeded between the east and the west. Against such currents the city of Van composes a minor obstacle, which they avoid on their more normal and northerly course. Always secure with a fleet on the lake and the passes of Mount Varag fortified, the true military value of the place only advances into first-rate importance when the centres of the hostile forces lie in Mesopotamia. It is screened in that direction by perhaps the most impenetrable section of the entire outer or Iranian arc of the peripheral mountains which support the tableland. [57] Moreover, the circumstance that the arc has snapped and sent out a splinter into the districts on the north, represented by the mountains in which the Great Zab has its source, and, further north, by the elevated but not impassable waterparting between the basin of Lake Van and that of the Araxes, has had the effect of concealing Van within the fork of a twofold parapet where it reposes with its back against the complex barrier and defies attack from the south or south-east. The approach from the west along the southern shore of the lake is interrupted by the spurs of the great range; and the Assyrian armies were compelled to make the détour by the plain of Melazkert, gaining the plateau by one of the passes north of Diarbekr and leaving it upon their return home through one of the passages east of Rowanduz where the sea of mountains settles down to a regular course. Such an immense circuit through a hostile country necessitated resources on a vast scale, the existence of which among the Assyrians fills the mind with admiration when we contemplate the squalor of the Oriental empires of the present day. But there can be no doubt that all the advantages lay on the side of their northern adversaries, to whom was offered a reasonable chance of annihilating their hosts, or, in the event of defeat, the secure alternative of shutting themselves up in their capital and there awaiting the passing over of the storm. These considerations serve to explain the comparative immunity and the rapid development of the empire of the successors of Sarduris the First; at a time, too, when Assyria was governed by such warlike monarchs as Shamshi-Ramman and Ramman-nirari. [58] It was reserved for Tiglath-Pileser the Third to beard the lion in his den, and to appear before the walls of Van. But even this gigantic figure failed to capture the citadel, although he
