Xenophon (circa 430–354 BC) was an ancient Greek philosopher, historian, soldier, mercenary, and a disciple of Socrates. As a historian, Xenophon is known for his works on the history of his own times, the sayings of his master Socrates, and the life in ancient Greece. Notably, he authored 'Anabasis,' which recounts the adventures of the Ten Thousand, a group of Greek mercenaries hired by Cyrus the Younger in an attempt to seize the Persian throne. This work is also mentioned as 'The History of Xenophon' and is a classic within military literature, often cited for its vivid description of soldier life and for its lessons on leadership and persistence. Xenophon's writing style is straightforward and practical, often characterized by his clear diction and vivid detail, and is marked by an emphasis on providing moral lessons and promoting virtuous conduct. Aside from 'Anabasis,' his notable works include 'Hellenica,' which serves as a continuation of Thucydides' 'History of the Peloponnesian War' and provides an account of Greek history from 411 to 362 BC, and 'Cyropaedia,' a partly historical, partly fictional biography of Cyrus the Great. Additionally, Xenophon's 'Memorabilia' defends Socrates against the charges that led to his trial and execution. Xenophon's works have been invaluable to historians for their insights into Greek culture, and his philosophic texts contribute to our understanding of Socratic thought.
