Plutarch's Lives of the Noble Greeks and Romans, commonly called Parallel Lives or Plutarch's Lives, is a series of biographies of famous men, arranged in tandem to illuminate their common moral virtues or failings. The surviving Parallel Lives, contain twenty-three pairs of biographies, each pair consisting of one Greek and one Roman, as well as four unpaired, single lives. It is a work of considerable importance, not only as a source of information about the individuals biographized, but also about the times in which they lived.

Plutarch's Lives, written at the beginning of the second century A.D., is a brilliant social history of the ancient world by one of the greatest biographers and moralists of all time. In what is by far his most famous and influential work, Plutarch reveals the character and personality of his subjects and how they led ultimately to tragedy or victory. Richly anecdotal and full of detail, Volume I contains profiles and comparisons of Romulus and Theseus, Numa and Lycurgus, Fabius and Pericles, and many more powerful figures of ancient Greece and Rome. The present translation, originally published in 1683 in conjunction with a life of Plutarch by John Dryden, was revised in 1864 by the poet and scholar Arthur Hugh Clough, whose notes and preface are also included in this edition.
