A Method of History by Travel and Observation
To write the Histories Herodotus traveled in person to Egypt, Babylon, the Black Sea coast, and further, interviewing local priests and inhabitants and observing famous ancient sites such as the pyramids and the walls of Babylon in the field; this method of history of "reading ten thousand books and traveling ten thousand li" was quite rare in the historical writing tradition of the time, and the vivid, detailed accounts of foreign customs from his pen are still among the most important references for the study of the historical ethnography of the peoples of the ancient Near East and the Mediterranean, though the accuracy of some of the anecdotal content has since been tested and revised by archaeological evidence.
