De rerum natura (On the Nature of Things) is a first-century BC didactic poem by the Roman poet and philosopher Lucretius (c. 99 BC â c. 55 BC) with the intent of explaining Epicurean philosophy to a Roman audience. The poem, written in some 7,400 dactylic hexameters, is divided into six untitled books, and explores Epicurean physics through richly poetic language and metaphors. Lucretius presents the principles of atomism; the nature of the mind and soul; explanations of sensation and thought; the development of the world and its phenomena; and explains a variety of celestial and terrestrial phenomena. The universe described in the poem operates according to these physical principles, guided by fortuna, "chance," and not the divine intervention of the traditional Roman deities.
This book has also been annotated, with additional information about the poetry and its author, including an overview,synopsis, manuscript history, the author's physics, responses, and biographical information.
