The Swerve: How the World Became Modern is Harvard Shakespeare scholar Stephen Greenblatt’s account of the rediscovery of Lucretius’s 1st-century poem De Rerum Natura, or On the Nature of Things, and the role its ideas played in triggering the Renaissance. Rather than tackling this topic head-on, Greenblatt approaches it through the story of Medieval papal secretary and bibliophile Poggio Bracciolini, who discovered the poem in a remote monastery in 1417.
Poggio Bracciolini, or Poggio the Florentine, was a Humanist scholar who worked in the papal court, and who was one of the most prolific bookhunters of the Medieval period. After the pope he was serving under was deposed, he went on a search for lost Classical manuscripts in remote monasteries around Europe. Many Classical works did not survive past their own time, either devoured by bookworms, decayed, written over, or simply forgotten--but others survived, as monks had copied some manuscripts repeatedly over the years. The copy of De Rerum Natura that Poggio found was one of these texts, tucked away in a isolated German monastery for centuries. A glance at the first few pages was all Poggio needed to see that he had found something of importance, as although Lucretius’s name was often mentioned in works by his contemporaries, none of his other works have ever been discovered. Although Poggio probably had some idea of the importance of the work, he probably had no idea of what the full impact of the poem would be; nor of the “dangerous” ideas within.
Lucretius’s poem itself is full of Epicurean ideas--that fortuna, chance, dictates the course of people’s lives, not the gods, that everything was made up of tiny atoms, the titular swerve--a principle of Epicurean physics that says atoms are constantly swerving into each other randomly, creating the infinite complexities of the universe, and so on. Greenblatt’s book focuses on how the recirculation of these ideas ultimately triggered the Renaissance. However, The Swerve only goes into this concept superficially. Greenblatt never really does explain “how the world became modern;” the poem clearly was just one factor in the complex start of the Renaissance, not its sole catalyst. But The Swerve never really touches on the other ideas and works that triggered the Renaissance, so the book seems to present On the Nature of Things as the period’s only cause. Greenblatt is at his best when retelling the story of an overlooked historical figure, Poggio Bracciolini, not when trying to convince the reader that one poem caused the whole of the Renaissance.
Although the book does have some flaws, such as its slightly superficial approach to the origins of the Renaissance, it’s also an extremely interesting read, and one that I highly recommend. Greenblatt’s writing style is easy to understand while still conveying the history of the period elegantly. Sacrificing some accuracy for a broader look at the impact of the poem ultimately works; The Swerve connects Poggio’s quest for lost manuscripts and his life with history from the Medieval period, Lucretius and his contemporaries around the first century, the discovery of charred manuscripts in the ruins of Pompeii, how Lucretius’s poem impacted history from his time onwards, and more. The Swerve contains interesting historical facts as well as a broad look at what caused the Renaissance, so if you’re interested in history at all, I absolutely recommend reading it.
