[40]. So much for the parts of Asia west of the Persians. But what is beyond the Persians, and Medes, and Saspires, and Colchians, east and toward the rising sun, this is bounded on the one hand by the Red Sea, and to the north by the Caspian Sea and the Araxes river, which flows toward the sun's rising.  [2] As far as India, Asia is an inhabited land; but thereafter, all to the east is desolation, nor can anyone say what kind of land is there.

[44]. But as to Asia, most of it was discovered by Darius. There is a river, Indus, second of all rivers in the production of crocodiles. Darius, desiring to know where this Indus empties into the sea, sent ships manned by Scylax, a man of Caryanda, and others whose word he trusted;  [2] these set out from the city of Caspatyrus and the Pactyic country, and sailed down the river toward the east and the sunrise until they came to the sea; and voyaging over the sea west, they came in the thirtieth month to that place from which the Egyptian king sent the above-mentioned Phoenicians to sail around Libya.  [3] After this circumnavigation, Darius subjugated the Indians and made use of this sea. Thus it was discovered that Asia, except the parts toward the rising sun, was in other respects like Libya.
