"The aim of this study is to track De Rerum Natura along two paths of satire. One is the broad boulevard of satiric literature from the beginnings of Greek poetry to the plays, essays, and broadcast media of the modern world. The other is the narrower lane of Roman verse satire, satura, whose canon begins in the Middle Republic with Ennius and Lucilius and closes with Juvenal, an author of the Flavian era. The first main portion of this book (chapters 2-3) focuses on Lucretius and Roman satura, while the following chapters broaden the scope to satiric elements of Lucretius more generally, but still with plenty of reference to the poets of Roman satura as satirists par excellence. By examining how Lucretius' poem employs the tools, techniques, and tactics of satire-by evaluating how and where in De Rerum Natura the speaker functions as a satirist-we gain, I argue, a fuller, richer understanding of how the poem works and how its poetry interacts with its purported philosophical program. Attention to the role of De Rerum Natura in the more specific tradition of Roman verse satire demonstrates that Lucretius' poem stands as a detour on the genre's highway, a swerve in the trajectory of satura. The numerous satiric passages and frequently satiric narrator of De Rerum Natura draw on earlier Roman satire, and in turn the poem influences the later satiric verse of Horace, Persius, and Juvenal. While De Rerum Natura is not in and of itself a member of the Roman genre of satire, it is an important player in the genre's development"--
