Readers in the Underworld: Lucretius, De Rerum Natura 3.912–1075

Readers have always acknowledged the comparatively clear macrostructure ofDe rerum natura3. It begins with aprooemiumin which is described the terrifying impact which the fear of death has on human lives, as well as the fact that Epicurus has provided a cure against this fear, namely his physical doctrines (1–93). Particular attention is paid to fears of an afterlife in which we have to suffer pain and grief in the underworld; cf., for instance, the programmatic lines 3.37–40 (translation by Ferguson Smith, which will be used throughout):Thisprooemiumis followed by a long passage (94–829) in which Lucretius explains the basics of Epicurean psychology and tries to show that the soul is (like the body) material and hence mortal; this last point is driven home with particular force in II. 417–829 where Lucretius lists twenty-five proofs for the mortality of the soul.
