Xenophon (ca. 430 to ca. 354 BCE) was a wealthy Athenian and friend of Socrates. He left Athens in 401 and joined an expedition including ten thousand Greeks led by the Persian governor Cyrus against the Persian king. After the defeat of Cyrus, it fell to Xenophon to lead the Greeks from the gates of Babylon back to the coast through inhospitable lands. Later he wrote the famous vivid account of this 'March Up-Country' ("Anabasis"); but meanwhile he entered service under the Spartans against the Persian king, married happily, and joined the staff of the Spartan king, Agesilaus. But Athens was at war with Sparta in 394 and so exiled Xenophon. The Spartans gave him an estate near Elis where he lived for years writing and hunting and educating his sons. Reconciled to Sparta, Athens restored Xenophon to honour but he preferred to retire to Corinth. Xenophon's Anabasis is a true story of remarkable adventures. "Hellenica, " a history of Greek affairs from 411 to 362, begins as a continuation of Thucydides' account. There are four works on Socrates (collected in Volume IV of the Loeb Xenophon edition). In "Memorabilia" Xenophon adds to Plato's picture of Socrates from a different viewpoint. The "Apology" is an interesting complement to Plato's account of Socrates' defense at his trial. Xenophon's "Symposium" portrays a dinner party at which Socrates speaks of love; and "Oeconomicus" has him giving advice on household management and married life. "Cyropaedia, " a historical romance on the education of Cyrus (the Elder), reflects Xenophon's ideas about rulers and government; the Loeb edition is in two volumes. We also have his "Hiero, " a dialogue on government; "Agesilaus, " in praise of that king; "Constitution of Lacedaemon" (on the Spartan system); "Ways and Means" (on the finances of Athens); "Manual for a Cavalry Commander;" a good manual of "Horsemanship;" and a lively "Hunting with Hounds. The Constitution of the Athenians, " though clearly not by Xenophon, is an interesting document on politics at Athens. These eight books are collected in the last of the seven volumes of the Loeb Classical Library edition of Xenophon.
