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.**** THE ECONOMIST records Socrates and Critobulus in a talk about profitable estate management, and a lengthy recollection by Socrates of Ischomachus' discussion of the same topic.
