When Tiglath Pilesar ascended the throne about the year 1130 B.C. the empire of Assyria, as his inscriptions show, had not as yet made any extensive conquests beyond the circle of the native country. The Muskai, _i.e._ the Moschi, whom we have found on the north-western slopes of the Armenian mountains, against whom Tiglath Pilesar first fought, had forced their way, as the cylinders tell us, into the land of Kummukh.[55] As the inhabitants of the land of Kummukh are conquered on the Tigris and forced into it, while others escape over the Tigris and defend a fortified city on the further side of the river, as the land itself is then incorporated with Assyria, we must obviously look for it at no great distance to the north on both shores of the Upper Tigris. We shall hardly be in error, therefore, if we take this land to be the district afterwards called Gumathene, on the Tigris, which Ammianus describes as a fruitful and productive land, _i.e._ as the canton of Amida.[56] The next conflicts of Tiglath Pilesar took place on the Lower Zab, _i.e._ at the south-eastern border of the Assyrian country. Further to the south, on the Zagrus, perhaps in the district of Chalonitis, or between the Lower Zab and the Adhim, or at any rate to the east, we must look for the land of Khumani and the land of Musri. The image at Karkar, Tiglath Pilesar's monument of victory, gives us information about the position of the land of Nairi. It comprises the mountain cantons between the Eastern Tigris and the upper course of the Great Zab, where that river traverses the land of Arrapachitis (Albak). The lake of the land of Nairi, to which the inscription of Karkar extends the rule of Tiglath Pilesar, and the upper sea from which auxiliaries come to the princes of the land of Nairi, are both, no doubt, Lake Van. The inhabitants of Nairi are not like those of the land of Kummukh, incorporated with Assyria, they have merely to pay a moderate tribute in horses and oxen. The campaign of Tiglath Pilesar against Karkamis (Karchemish) proves that the dominion of Assyria before his reign did not reach the Euphrates. He marches against the land of Aram and has then to fight with the army of Karchemish on this side, _i.e._ on the east side of the Euphrates; the results which he obtained on this campaign to the west of the Euphrates he does not himself rate very highly. We saw that in the end he remained at a disadvantage in his contest with Babylon. On the other hand, in campaigns which took place in years subsequent to the attempt against Karchemish, he must have forced his way to the west far beyond the Euphrates, in order to be able to boast on the monument at Karkar "that he ruled from the sea of Nairi as far as the great sea of the west land," _i.e._ to the Mediterranean. Hence we have to assume that he went forth from Karchemish westwards almost as far as the mouth of the Orontes. We should be more accurately
