De rerum natura

the long version

This is regarded as a seminal text of Epicurean science and philosophy. Epicurians discarded both the idea of immortality and the superstitious worship of wilful gods for a life of serene contentment in the available pleasures of nature. Lucretius (c100-c55BC), in elucidating this belief, steers the reader through an extraordinary breadth of subject matter, ranging from the indestructibility of atoms and the discovery of fire to the folly of romantic love and the phenomena of clouds and rainstorms.
