Biography
The thread of a life.
Titus Lucretius Carus was a Roman poet of the generation of Cicero and Caesar who set out the philosophy of Epicurus in On the Nature of Things, a Latin poem in six books. Almost nothing reliable is known of his life; the poem presents him as a teacher who uses an account of atoms, void and chance to free readers from fear of the gods and of death.
The addressee
The poem is addressed to Gaius Memmius, praetor in 58 BCE, a Roman politician who also counted poets among his circle.
A reported death
The Life of Virgil attributed to Donatus dates his death to 55 BCE, on the day Virgil assumed the toga of manhood.
Cicero’s letter
In February 54 BCE Cicero writes to his brother Quintus about the poems of Lucretius, the earliest secure testimony.
Jerome’s legend
Jerome’s Chronicle reports a love potion, madness, books written in lucid intervals and suicide.
Rediscovery and print
Poggio Bracciolini recovers a manuscript in 1417; the first printed edition appears at Brescia around 1473.
Understanding a life in depth
01An almost unknown life
No ancient biography of Titus Lucretius Carus survives. The poem names its addressee, Gaius Memmius, praetor in 58 BCE, but says nothing about the poet’s family, home or career. A letter of Cicero shows the work circulating by February 54 BCE. Jerome’s Chronicle, written around 380 CE, dates his birth to about 94 BCE and reports madness, a love potion and suicide in his forty-fourth year; the Life of Virgil attributed to Donatus links his death to 55 BCE. These late and partly contradictory notices explain the conventional dates of c. 99 to c. 55 BCE and warn against reading the poem through legend.
02An Epicurean poem for Rome
Lucretius wrote in the generation of Cicero and Caesar, when Epicureanism attracted Roman readers and was taught in Italy, notably by Philodemus in Campania. He chose the Latin hexameter, the metre of Ennius and of the Greek philosopher-poet Empedocles, although Epicurus was said to distrust poetry. He laments the poverty of his native tongue and forges a vocabulary for Greek ideas: first beginnings, seeds of things, first bodies. Addressing Memmius in a troubled time for the homeland, he presents Epicurus as a liberator who broke the grip of fearful religion, and offers his verse as honey on the rim of a bitter cup.
03The architecture of six books
The six books advance in pairs. Books 1 and 2 establish that nothing comes from nothing, that everything is atoms and void, that atoms move and swerve, and that worlds are countless. Books 3 and 4 show that mind and spirit are mortal, so that death is nothing to us, and explain perception through thin films, together with dreams and the passion of love. Books 5 and 6 describe the birth and end of our world, the origins of life and civilization, and phenomena such as thunder, earthquakes, magnets and disease, closing with the plague of Athens. Repetitions, unkept promises and the abrupt ending suggest that the poem was left unfinished.
04Survival, rediscovery and readers
Virgil, Ovid and Seneca read and echoed the poem, while the Christian writers Lactantius and Arnobius quoted or imitated it, often in order to oppose it. Its text survives chiefly through two ninth-century manuscripts now in Leiden. In 1417 the humanist Poggio Bracciolini found a copy in a monastic library north of the Alps, and the first printed edition appeared at Brescia around 1473. Machiavelli copied the poem by hand, Montaigne annotated Denys Lambin’s edition of 1563 and Gassendi revived Epicurean atomism. Lachmann’s edition of 1850 became a landmark of textual criticism. Popular accounts in which a single rediscovery launched modernity are disputed by specialists.
Preserved by a few medieval manuscripts and rediscovered in 1417, the poem fed early modern debates on atomism, providence and the soul, from Montaigne and Gassendi to the materialists of the Enlightenment. It remains a chief source for Epicurean physics and a major work of Latin poetry, though how faithfully it renders its Greek model is still debated.
