Epicurus wrote in prose. Lucretius chose to pass on his doctrines to the Roman reader through the medium of verse, using the metre of Homer's Iliad and Odyssey, the epic hexameter.
Titus Lucretius Carus (c. 99 BC – c. 55 BC) was a Roman poet and philosopher. His only known work is the epic philosophical poem "De Rerum Natura" about the tenets and philosophy of Epicureanism, and which is usually translated into English as On the Nature of Things.
Very little is known about Lucretius's life; the only certain fact is that he was either a friend or client of Gaius Memmius, to whom the poem was addressed and dedicated.
