Cyropaedia: the Education of Cyrus

Book-length biography. Xenophon the Athenian was born 431 B.C. He was a pupil of Socrates. He marched with the Spartans, and was exiled from Athens. Sparta gave him land and property in Scillus, where he lived for many years before having to move once more, to settle in Corinth. He died in 354 B.C. According to Wikipedia: "Cyrus the Great (c. 600 BC or 576 BC–530 BC), also known as Cyrus II or Cyrus of Persia, was the founder of the Persian Empire under the Achaemenid dynasty.[6] Under his rule, the empire embraced all the previous civilized states of the ancient Near East, expanded vastly and eventually conquered most of Southwest Asia and much of Central Asia, parts of Europe and Caucasus. From the Mediterranean sea and Hellespont in the west to the Indus River in the east, Cyrus the Great created the largest empire the world had yet seen."
