Xenophon the Athenian was born 431 BCE. He was a pupil of Socrates. He marched with the Spartans & was exiled from Athens. Sparta gave him land & property in Scillus, where he lived for many years before having to move once more, to settle in Corinth. He died in 354. The Agesilaus summarises the life of his Spartan friend & king, whom he met after the events of the Anabasis. The Anabasis is his story of the march to Persia to aid Cyrus, who enlisted Greek help to try & take the throne from Artaxerxes, & the ensuing return of the Greeks, in which Xenophon played a leading role. This occurred between 401 & 3/399 BCE.
