This book investigates whether Plutarch's Parallel Lives function primarily as historical records or as complex moral and psychological inquiries into the nature of virtue and vice. Tim Duff, a scholar of Greek literature, examines the text not merely as a source for historical data, but as a deliberate construction of character and cultural identity. He argues that Plutarch utilizes the lives of prominent Greeks and Romans to engage with the intellectual concerns of the second century AD, specifically regarding education, morality, and the synthesis of Hellenic and Roman traditions.

Experts recognize this work as a significant contribution to the study of Plutarch, noting its success in shifting the focus from historical accuracy to literary intent. Readers frequently highlight the clarity of the prose, which makes complex classical scholarship accessible to those interested in ancient biography and moral philosophy.
