"Parallel Lives" is a work by the ancient Greek philosopher Plutarch, consisting of a series of biographies that compare the lives of notable Greeks and Romans. Each pair of biographies highlights similarities and differences in their characters, achievements, and moral lessons, aiming to illustrate the virtues and vices of each individual. The text serves as both a historical account and a moral guide, emphasizing the importance of character in shaping one's destiny. By juxtaposing figures like Alexander the Great and Julius Caesar, Plutarch encourages readers to reflect on the qualities that lead to greatness and the consequences of one's choices.
