The Greek historian, politician and general Xenophon (430-354 BC) in the fields of history, economics and history. He was a student of Socrates (470-399 BC). Xenophon fought as an officer in an army of Greek mercenaries under the rebellious Cyrus I (657-600 BC) against his brother Artaxerxes II (453-359 BC) and led 10,000 Greeks back home from Babylon. He described this in his writing "Anabasis" (Train to the Interior). He is regarded as an outstanding, versatile specialist author. On his long journey through the Middle East, he also became acquainted with the alcoholic beverages typical at the time from what is now Armenia. He spent large parts of his life as a landowner on the Greek peninsula of Peloponnese, from which he derived his excellent knowledge of agriculture, viticulture and animal husbandry.
