This collection of essays, written by former pupils, celebrates the career of Jasper Griffin, one of the foremost modern scholars of classical epic. The volume surveys the epic tradition from the eighth century BC to the nineteenth century of our era. Individual chapters focus on: Homer and the oral epic tradition; Homer in his religious context; Herodotus and Homer; Hellenistic epic; Virgil in his literary context; Virgil in his political-cultural context; the Augustan poets and the Aeneid; Statius' Thebaid; Old English and Old Irish epic; Renaissance epic: Tasso and Milton; and the Victorians. The aim of the book is to situate writers of epic in their literary and cultural contextsan enterprise captured in the term "interaction" in the title. The chapters singly offer insights into some of the foundational poems of the European epic tradition and together take a bold, holistic look at that tradition.
