Xenophon (c. 430 – 354 BCE) was an ancient Greek philosopher, historian, soldier, mercenary, and a disciple of Socrates. As an author, he is known for his writings on the history of his own times, the sayings of Socrates, and the life in Greece and the Persian Empire. His most famous work is 'Anabasis' which chronicles the expedition of Cyrus the Younger, a Persian prince, against his brother King Artaxerxes II and the subsequent return of the Greek mercenaries known as the Ten Thousand back to Greece after Cyrus's death in the Battle of Cunaxa. The work not only serves as a historical account but also exhibits his knack for leadership and understanding of military tactics. Xenophon's other significant works include 'Hellenica', which is a continuation of Thucydides's history of the Peloponnesian War, 'Cyropaedia', a partly fictional account of Cyrus the Great's education and reign, and 'Memorabilia', a defense of Socrates's life and philosophy. His literary style is straightforward and clear, differing from the often complex and ornate prose of his contemporaries, which made his works accessible and instructional. Xenophon's contributions to literature and history have been invaluable in providing insights into the social, political, and military aspects of ancient Greece and Persia, and his works continue to be studied for their historical value and their depiction of Socratic philosophy.
