land of the Indus, were exported from the land about 1000 B.C., under names given to them by the Aryas, and therefore the Aryas must have been settled there for centuries previously. For this reason, and it is confirmed by facts which will appear further on, we may assume that the Aryas descended into the valley of the Indus about the year 2000 B.C., _i.e._ about the time when the kingdom of Elam was predominant in the valley of the Euphrates and Tigris, when Assyria still stood under the dominion of Babylon, and the kingdom of Memphis was ruled by the Hyksos. We have no further accounts from the West about the Aryas till the year 500 B.C., and later. It is not improbable that the arms of Cyrus reached the Indus. The Astacenes and Assacanes are said to have been subject to the Medes after the Assyrians; then Cyrus, the son of Cambyses, imposed tribute upon them.[13] As Cyrus subjugated Bactria, fought in Arachosia, and marched through Gedrosia, we may assume that he compelled the nations of the Aryas on the right bank of the Indus to pay tribute. It was in conflict with the Derbiccians, to whom the Indians sent elephants as auxiliaries, that Cyrus, according to the account of Ctesias, was slain. Darius, as Herodotus tells us, sent messengers to explore the land of the Indus. Setting out from Arachosia, they proceeded from Caspapyrus (Kaçpapura), a city which, according to Hecatæus, belonged to the Gandarii[14]--_i.e._ without doubt from Kabura (Cabul) down the Indus to the sea. According to Herodotus' account the Gandarii, together with the Arachoti and Sattagydæ, paid 170 talents of gold yearly; the rest of the Indians paid a larger tribute than any other satrapy--360 talents of gold.[15] The Indians who paid this tribute were, according to Herodotus, the most northerly and the most warlike of this great nation. They dwelt near the city of Caspapyrus, _i.e._ near Cabul; their mode of life was like that of the Bactrians, and they obtained the gold from a sandy desert, where ants, smaller than dogs, but larger than foxes, dug up the gold-dust.[16] Darius tells us himself, in the inscriptions of Persepolis, that the Gandarii and the Indians were subject to him. Like Herodotus, these inscriptions comprise the tribes of the Aryas on the right bank of the Indus as far down as Cabul under the name of Indians, so that the Açvakas were included among them. The Gandarii, as is shown by their vicinity to and connection with the Arachoti, lay to the south of Cabul. In the epos of the Indians the daughter of the king of the Gandharas is married to the king of the Bharatas, who lie between the Yamuna and the Ganges, and the Buddhist writings speak of the Brahmans of the Gandarii as the worst in India.[17] In the campaign of Xerxes, Herodotus separates the Gandarii from the rest of the Indians who are subject to the Persian kingdom. The first, he says, were armed like the Bactrians; with the rest marched the
