Ancient biography is now a well-established and popular field of study among classicists as well as many scholars of literature and history more generally. In particular biographies offer important insights into the dynamics underlying ancient performance of the self and social behaviour, issues currently of crucial importance in classical studies. They also raise complex issues of narrativity and fictionalization. This volume examines a range of ancient texts which are or purport to be biographical and explores how formal narrative categories such as time, space and character are constructed and how they address (highlight, question, thematize, underscore or problematize) the borderline between historicity and fictionality. In doing so, it makes a major contribution not only to the study of ancient biographical writing but also to broader narratological approaches to ancient texts.
