With his De rerum natura, the Roman poet Lucretius set out to do no less than render the entire universe as a text, from the most minute motions of single atoms to events on a cosmic scale. Lucretius drew upon Epicurus’ Greek natural philosophy, but in order to attract and convince his Roman audience, he wove it into the fabric of Latin poetry. The present book proposes to read Lucretius’ philosophical epic as a four-fold process of translation that transforms Epicurean doctrine on linguistic, literary, cultural, and conceptual levels. This process, as will be demonstrated, is reflected in Lucretius’ vocabulary of translation. The poet’s own creative use of language – his daedalic tongue – is the link that holds his poetic physics and physical poetics together.
