From the publisher's description:
"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. . . . [Biographies] 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."
