Abstract
The chapter discusses the ways in which various Greek writers engaged with the complexities of the Persian Empire, especially Herodotus, Xenophon, Aristotle, and some fourth-century writers (fragmentary) of Persika. It examines the tension between Greek hostility towards Persia and the conventional stereotypes, and their need to understand more about the Empire in a new form of ethnography. New insights into the Persian Empire (and new evidence) encourage returning to the Greek writers afresh and examining them from different angles: the chapter argues that amidst the clichés, there was also a seriousness and urgency in the fourth century about trying to understand the Persian Empire and its monarchy.
