The Cyropaedia (or Cyropedia) is a biography of Cyrus the Great, written in the early 4th century BC by the Athenian gentleman-soldier, and student of Socrates, Xenophon of Athens. The Latinized title Cyropaedia derives from Greek Kúrou paideía (Κύρου παιδεία), meaning "The Education of Cyrus". Aspects of it would become a model for medieval writers of the genre known as mirrors for princes.
