Cyrus the Great

It was here that he obtained the materials for what he has written in respect to the Medes and Persians, and to the history of Cyrus. After spending some time in these countries, he went on by land still further to the eastward, into the heart of Asia. The country of Scythia was considered as at "the end of the earth" in this direction. Herodotus penetrated for some distance into the almost trackless wilds of this remote land, until he found that he had gone as far from the great center of light and power on the shores of the Ægean Sea as he could expect the curiosity of his countrymen to follow him. He passed thence round toward the north, and came down through the countries north of the Danube into Greece, by way of the Epirus and Macedon. To make such a journey as this was, in fact, in those days, almost to explore the whole known world.
