Lucretius' 'De rerum natura', one of the greatest Latin poems, worked a powerful fascination on Virgil and Horace, and continued to be an important model for later poets in antiquity and after, including Milton. This innovative set of studies on the reception of Lucretius is organized round three major themes: history and time, the sublime, and knowledge. The 'De rerum natura' was foundational for Augustan poets' dealings with history and time in the new age of the principate. It is also a major document in the history of the sublime; Virgil and Horace engage with the Lucretian sublime in ways that exercised a major influence on the sublime in later antique and Renaissance literature. The 'De rerum natura' presents a confident account of the ultimate truths of the universe; later didactic and epic poets respond with varying degrees of certainty or uncertainty to the challenge of Lucretius' Epicurean gospel.
