Plutarch defined for all ages the character of Greek and Roman moral identity. He studied what constitutes the best in a human being, and which, in turn, determines a person’s role in the world. Blending history and biography, Plutarch evokes the characters of great leaders in history. He systematically pairs a Greek with a Roman, comparing characters and lives with similar careers so as to serve his particular goal of moral instruction. In vivid prose, he describes the awesome spectacle of the actions of men of enormous desires and ambitions responding to impossible situations.
