The fullest surviving account of Epicurean philosophy, and one of the great long poems in Latin.
Argues that everything, including the soul, is made of tiny particles moving in empty space, so the gods do not control the world and death is nothing to fear.
Describes a universe with no plan behind it, where living things arise and change through natural processes over long stretches of time.
Shaped early modern science and thought, as writers and thinkers such as Montaigne and Pierre Gassendi drew on its picture of atoms when it returned to wide circulation in the Renaissance.
Inspired later poets, most clearly Virgil, whose poems echo its language and its hope of understanding how nature works.

A legend of madness

Saint Jerome later claimed a love potion drove the poet mad, and that he wrote between fits.
Praised by Cicero

Cicero read it soon after and wrote to his brother that it showed flashes of genius and great skill.
Left unfinished

The poem seems unfinished, with repeated lines and rough spots, and ends abruptly describing a plague in Athens.
Found in a monastery

In 1417 the book hunter Poggio Bracciolini found a copy in a German monastery after centuries of neglect.
