This is the first detailed analysis of the fate of Lucretius' De rerum natura from its composition in the 50s BC to the creation of our earliest extant manuscripts during the Carolingian Age. Close investigation of the knowledge of Lucretius' poem among writers throughout the Roman and medieval world allows fresh insight into the work's readership and reception, and a clear assessment of the indirect tradition's value for editing the poem. The first extended analysis of the 170+ subject headings (capitula) that intersperse the text reveals the close engagement of its Roman readers. A fresh inspection and assignation of marginal hands in the poem's most important manuscript (the Oblongus) provides new evidence about the work of Carolingian correctors and offers the basis for a new Lucretian stemma codicum. Further clarification of the interrelationship of Lucretius' Renaissance manuscripts gives additional evidence of the poem's reception and circulation in fifteenth-century Italy.

Lucretius' account of the origin of life, the origin of species, and human prehistory is the longest and most detailed account extant from the ancient world. It gives an anti-teleological mechanistic theory of zoogony and the origin of species that does away with the need for any divine aidor design in the process, and accordingly it has been seen as a forerunner of Darwin's theory of evolution. This commentary locates Lucretius in both the ancient and modern contexts, and treats Lucretius' ideas as very much alive rather than as historical concepts. The recent revival of creationismmakes this study particularly relevant to contemporary debate, and indeed, many of the central questions posed by creationists are those Lucretius attempts to answer.

Brown demonstrates how Florentine thinkers used Lucretius—earlier and more widely than has been supposed—to provide a radical critique of prevailing orthodoxies. She enhances our understanding of the “revolution” in sixteenth-century political thinking and our definition of the Renaissance within newly discovered worlds and new social networks.

After its rediscovery in 1417, Lucretius’s Epicurean didactic poem De Rerum Natura threatened to supply radicals and atheists with the one weapon unbelief had lacked in the Middle Ages: good answers. Scholars could now challenge Christian patterns of thought by employing the theory of atomistic physics, a sophisticated system that explained natural phenomena without appeal to divine participation, and argued powerfully against the immortality of the soul, the afterlife, and a creator God. Ada Palmer explores how Renaissance readers, such as Machiavelli, Pomponio Leto, and Montaigne, actually ingested and disseminated Lucretius, and the ways in which this process of reading transformed modern thought. She uncovers humanist methods for reconciling Christian and pagan philosophy, and shows how ideas of emergent order and natural selection, so critical to our current thinking, became embedded in Europe’s intellectual landscape before the seventeenth century. This heterodoxy circulated in the premodern world, not on the conspicuous stage of heresy trials and public debates, but in the classrooms, libraries, studies, and bookshops where quiet scholars met the ideas that would soon transform the world. Renaissance readers—poets and philologists rather than scientists—were moved by their love of classical literature to rescue Lucretius and his atomism, thereby injecting his theories back into scientific discourse. Palmer employs a new quantitative method for analyzing marginalia in manuscripts and printed books, exposing how changes in scholarly reading practices over the course of the sixteenth century gradually expanded Europe’s receptivity to radical science, setting the stage for the scientific revolution.
