Plutarch's 'Parallel Lives,' written at the beginning of the second century A.D., form a brilliant social history of the ancient world. They were originally presented in a series of books that gave an account of one Greek and one Roman life, followed by a comparison of the two: Theseus and Romulus, Alcibiades and Coriolanus, Demosthenes and Cicero, Demetrius and Antony. Plutarch was interested in the personalities of his subjects and on the way their characters molded their actions, leading them to tragedy or victory. He was a moralist of the highest order. Plutarch was a man of immense erudition who had traveled widely throughout the Roman Empire, and the Lives are richly anecdotal and full of detail. They were the principal source of Shakespeare's Roman plays.
