This is an edited collection by a distinguished team of scholars on the philosopher and poet Philodemus of Gadara (ca. 110-40 BC). The discovery of his library at Herculaneum, and the editing and gradual publication of the material, has reawakened interest in the philosophical and historical importance of his work. Philodemus presents us with a poetic theory of interest in itself, and several of his treatises provide us with instances of how poetry was seen as providing moral paradigms and guidance. These essays explore the many facets of Philodemus's work and the relationship between them, offering a critical survey of recent trends and developments in scholarship on Philodemus in particular and Hellenistic literary theory in general.
