It’s fairly clear, even after reading only a few verses, why Lucretius’s didactic poem, On the Nature of Things - De Rerum Natura - made such an impact on thought, philosophy, religion and science in the Renaissance. It must have been like a lighthouse in the dark night; a “Eureka” moment for many of the age’s thinkers.
For others, especially the church leaders, it must have arrived like a mortar shell among their intellectual certainties and complacencies; shattering walls and window. An act of war that threatened to tear down whole schools of thought and belief.
While today his descriptions of atoms, void, and immortal substance may seem obvious and even a little quaint, they were revelations then, in the Renaissance. They shook the comfortable world picture of the Renaissance and challenged both faith and science.
Yet Lucretius wrote his poem in the time of Julius Caesar, before the Christian church even began. Then it was lost for more than 1,400 years, to be rediscovered by Poggio Bracciolini in 1417. Poggio was hunting lost manuscripts through European monasteries, trying to copy them so he could restore the lost words of the Romans for everyone to read. His discovery of On the Nature of Things was serendipitous in the extreme,* but it opened a Pandora’s box of effects.
On the Nature of Things is not an easy read. Totaling 7,400 lines, it is written in hexameters, the standard unrhymed six-beat lines in which Latin poets like Virgil and Ovid, imitating Homer’s Greek, cast their epic poetry. Divided into six untitled books, the poem yokes together moments of intense lyrical beauty, philosophical meditations on religion, pleasure and death, and complex theories of the physical world, the evolution of human societies, the perils and joys of sex, and the nature of disease. The language is often knotty and difficult, the syntax complex, and the overall intellectual ambition astoundingly high.
So it’s a tough, challenging read, as much so today as it ever was. I’m reading it, but have to admit it’s a bit of a slog, even in the modern Penguin edition.
Omnis cum in tenebris praesertim vita laboret.
Life is one long struggle in the dark.
Book II, line 54.
It’s astounding how anyone in Caesar’s day could by reason, logical, analysis and inference alone – no highly technical equipment, no advanced mathematics, no electron microscopes, no particle colliders, no Hubble telescope – deduce the structure of the universe was based on atoms. And then to infer that those atoms were constantly in motion, indestructible and timeless.
That’s what the Epicurean philosophers did. Lucretius, perhaps the last of them (or certainly at least the last outstanding Epicurean) put their theories and ideas together into one long, rhetorical poem to teach his fellow Romans what Epicureans stood for.
In doing so, Lucretius deconstructs and dismisses the theories of his contemporaries about the nature of the universe, using the same tools of thought and reason. Those theories – now long dismissed – fossilized into accepted dogma for many centuries before his book was rediscovered. On the Nature of Things had no less an impact on Renaissance thought than On the Origin of Species had on modern thought.
