The Cyropaedia, sometimes spelled Cyropedia, is a largely fictional biography of Cyrus the Great the founder of Achaemenid Empire, the first Persian Empire. It was written around 370 BC by the Athenian gentleman-soldier, and student of Socrates, Xenophon of Athens. The Latinized title Cyropaedia derives from Greek Kúrou paideía meaning "The Education of Cyrus". Aspects of it would become a model for medieval writers of the genre known as mirrors for princes. In turn it was a strong influence upon the most well-known but atypical of these, Machiavelli's The Prince, which was an important influence in the rejection of medieval political thinking, and the development of modern politics. However, unlike most "mirrors of princes", and like The Prince, whether or not the Cyropaedia was really intended to describe an ideal ruler is a subject of debate.In substance, the Cyropaedia is "a political romance, describing the education of the ideal ruler, trained to rule as a benevolent despot over his admiring and willing subjects."Although it is "generally agreed" that Xenophon "did not intend Cyropaedia as history", it remains unclear whether this work was intended to fit into any other classical genre known before. Its validity as a source of Achaemenid history has been repeatedly questioned, and numerous descriptions of events or persons have been determined to be in error.However, it is not clear that the work was intended to be used this way.Despite such doubts, it has been argued that Xenophon's Cyropaedia offers a glimpse of the character of Cyrus the Great of Achaemenid Persia. The source gives "an artist's portrait" of Cyrus as "the Ideal Ruler and the best form of Government", a description that "could not have been painted had there not been a credible memory of such a Cyrus".[4] Xenophon (c. 431 - 355 BC) was not a contemporary of Cyrus (c. 580 - 530 BC) and it is likely that at least some of the information about Persia was based on events that occurred at the later Achaemenid court. Xenophon had been in Persia himself, as part of the "Ten Thousand" Greek soldiers who fought on the losing side in a Persian civil war, events which he recounted in his Anabasis. It is also possible that stories of the great King were recounted (and embellished) by court society and that these are the basis of Xenophon's text.
