  Plutarch of Chaeronea in Boeotia (ca. 45–120 CE) was a Platonist philosopher, best known to the general public as author of his “Parallel Lives” of paired Greek and Roman statesmen and military leaders. He was a voluminous writer, author also of a collection of “Moralia” or “Ethical Essays,” mostly in dialogue format, many of them devoted to philosophical topics, not at all limited to ethics.
