If Plutarch is commonly associated with biographies and moral instruction, this volume reveals a far broader and more complex intellectual landscape. Plutarch on DIAITA: Lifestyle, Politics, Well-being, and Conviviality explores how everyday practices—food, health, pleasure, self-discipline, and convivial interaction—were understood in antiquity as central expressions of ethics, political culture, and social identity. Through a collection of stimulating and carefully argued studies, the book examines ancient reflections on well-being, leadership, moderation, and communal life, showing how closely private conduct and public values were intertwined. Beyond its relevance for Classical Studies, the volume invites contemporary readers to reconsider enduring questions about balance, sociability, and the relationship between individual habits and collective life.
