This Companion volume offers fifteen original essays on the Hellenistic world and is intended to complement and supplement general histories of the period from Alexander the Great to Kleopatra VII of Egypt. Each chapter treats a different aspect of the Hellenistic world - religion, philosophy, family, economy, material culture, and military campaigns, among other topics. The essays address key questions about this period: To what extent were Alexander’s conquests responsible for the creation of this new ‘Hellenistic’ age? What is the essence of this world and how does it differ from its Classical predecessor? What continuities and discontinuities can be identified? Collectively, the essays provide an in-depth view of a complex world. The volume also provides the most recent bibliography on the topics along with recommendations for further reading.
