Iranian table-land. From the inscriptions of Tiglath Pilesar II., it is clear that he advanced along the same table-land as far as the Hilmend and the Arachoti, if not as far as Bactria. Among the lands subjugated in 745 B.C., he enumerates Nisaa, Zikruti, and Arakuttu. In Nisaa we cannot mistake Nisæa in the east of Media (p. 31). The Zikruti were no doubt the Sagartians of Herodotus, the Açagarta of the old Persian inscriptions.[27] Arakuttu represents in a Semitic form the name of the Arachoti, the Harauvati of the Achæmenids (p. 8). So far as we can at present judge from inscriptions, the successors of Tiglath Pilesar did not carry their campaigns further to the east of Iran, and we can assert with certainty of both the sovereigns who raised the power of Assyria to its summit, Esarhaddon and Assurbanipal (681-626 B.C.), that they made no conquests in this direction.

If the inscriptions of the Assyrians leave us in almost total darkness about Bactria, the Medo-Persian epic poetry can give us full information about the country. When Ninus, king of Assyria, had subjugated all the nations of Asia as far as the Nile and the Tanais, he made an attempt upon Bactria, but without success. The entrance into the land was difficult, the number of warriors great, and they knew how to fight bravely. Then Ninus collected an army of two millions of soldiers, which was opposed by Oxyartes, the king of the Bactrians, with 400,000 men. When the Assyrian army came in detachments out of the passes, Oxyartes attacked and drove them back into the mountains with the loss of 100,000 men. The army of Ninus then combined, outnumbered and overcame the Bactrians, and scattered them into their cities, which Ninus took with little trouble. But Bactra, where was the palace of the kings, was large and well supplied, and had a very strong citadel in a high position, while the city extended over the plain. It resisted for a long time, till Semiramis ascended the citadel, and Ninus was enabled to take possession of the treasures of gold and silver which were in Bactra. At a later time Semiramis collected her vast army for the invasion of India in Bactria, and returned to Bactra after she had been defeated on the Indus, and had lost two-thirds of her army (II. 10). Such are the descriptions given by the epic poetry of the Medes and Persians, in the account of the rise of Assyria and subjugation of Bactria. The Bactrians are again brought forward in the narrative of the overthrow of Assyria, which was the proper theme of these poems. When Sardanapalus has already thrice defeated the Medes and Babylonians, a strong force comes to his assistance from Bactria. The leader of the Medes determines to attack this first, if it would not join in the contest for freedom against Assyria. The Bactrians joined the Medes, the power of Assyria was broken, and Nineveh destroyed (III. 253).

From these poems it follows that in the first half of the sixth century B.C., in which the Medo-Persian epic attained its original form, the tradition, or at any rate the opinion, existed among the minstrels of Media that a powerful kingdom and large metropolis once existed in Bactria, the situation of which is correctly described. This kingdom possessed a strong citadel and abundant treasures, and could put in the field a large army of brave warriors. Without such a conception they could not represent the first attack of the Assyrians on Bactria as a failure, the second as successful only after considerable time and trouble had been spent, and the conquest as the last and greatest achievement of Ninus, the mightiest sovereign of Assyria, which he only performed with the aid of Semiramis.

The inscriptions of the Assyrians have already informed us that no dominion of Assyria over Eastern Iran existed in the earliest period of the kingdom; on the contrary, even when her power was at the highest Assyria could only carry on temporary excursions into that region. The western part of the country was first trodden by the armies of Shalmanesar II.; his inscriptions mention tribute of the Medes, and from the inscriptions of his successors it is distinctly clear that only the nations of Western Iran were tributary dependants of the kings of Asshur from the period of Tiglath Pilesar, i. e. from the middle of the eighth century B.C., till the period of Phraortes and Cyaxares of Media, i. e. till the middle of the seventh century B.C.[28]

The conquests of Cyrus, who overthrew the power of the Medes, founded the Persian empire, and extended it to the east, would give us more accurate information about Eastern Iran if connected accounts of these were in existence. Herodotus contents himself with stating that Cyrus, after subjugating the Lydians, determined to march against the Bactrians and Sacæ. He conquered all the nations of Upper Asia, one after the other, without omitting any.[29] Ctesias relates that the Bactrians after a doubtful battle submitted voluntarily to Cyrus. According to the account of Xenophon, the Hyrcanians, Cadusians, and Sacæ joined Cyrus, and in the fragments of Nicolaus also the Hyrcanians, Parthians, and "the other nations" passed over to Cyrus immediately after the conquest of the Medes. However this may be, there is no doubt that the east of Iran was subject to Cyrus. He marched through the land of the Arachoti, entered into relations with the Ariaçpas (p. 8), and subjugated the Gandarians on the south of the Cabul. He is also said to have imposed tribute on the Açvakas to the north of the river (IV. 384). The Sogdiani, in any case, were his vassals. On a stream which flows into the Jaxartes he built a fortress called by his own name, known to the Greeks as Cyresbata (ultima Cyra, or with others Cyropolis), i. e. the furthest Cyrus. The walls and citadels were strong and spacious, and in the neighbourhood were six other citadels.[30] The value placed by Cyrus on the regions of Eastern Iran is not only clear from these fortresses, but may be deduced from the statement that his second son Bardya, whom the Greeks call Smerdis, was intrusted with the government of Bactria, if indeed the statement is genuine.[31]

The nations and condition of Eastern Iran can be ascertained more clearly from the inscriptions of Darius. According to his inscription at Behistun, his empire in that direction comprised the Parthians, Sarangians, Areians, Chorasmians, Bactrians, Sogdiani, Gandarii, Sattagydæ, Arachoti, and Sacæ; and to these the Idhus, i. e. the Indians on the right bank of the upper course of the Indus, are added in the inscriptions of Persepolis and Naksh-i-Rustem.[32] Further information is
