Lucretius

Very little is known about Lucretius's life; the only certainty is that he was either a friend or client of Gaius Memmius, to whom the poem was addressed and dedicated. De rerum natura was a considerable influence on the Augustan poets, particularly Virgil (in his Aeneid and Georgics, and to a lesser extent on the Eclogues) and Horace. The work was almost lost during the Middle Ages, but was rediscovered in 1417 in a monastery in Germany by Poggio Bracciolini. It played an important role both in the development of atomism (Lucretius was an important influence on Pierre Gassendi) and the efforts of various figures of the Enlightenment era to construct a new Christian humanism.

Virtually nothing is known about the life of Lucretius, and there is insufficient basis for a confident assertion of the dates of Lucretius's birth or death in other sources. A brief biographical note is found in Aelius Donatus's Life of Virgil, which seems to be derived from an earlier work by Suetonius. The note reads: "The first years of his life Virgil spent in Cremona until the assumption of his toga virilis on his 17th birthday (when the same two men held the consulate as when he was born), and it so happened that on the very same day Lucretius the poet passed away." However, although Lucretius certainly lived and died around the time that Virgil and Cicero flourished, the information in this particular testimony is internally inconsistent: if Virgil was born in 70 BC, his 17th birthday would be in 53. The two consuls of 70 BC, Pompey and Crassus, stood together as consuls again in 55, not 53. Another, yet briefer, note is found in the Chronicon of Donatus's pupil, Saint Jerome. Writing four centuries after Lucretius's death, he enters under the 171st Olympiad: "Titus Lucretius the poet is born." If Jerome is accurate about Lucretius's age (43) when Lucretius died (discussed below), then it may be concluded he was born in 99 or 98 BC. Less specific estimates place the birth of Lucretius in the 90s BC and his death in the 50s BC, in agreement with the poem's many allusions to the tumultuous state of political affairs in Rome and its civil strife. • Illustration — Start of late 15th-century illuminated manuscript of De rerum natura Lucretius probably was a member of the aristocratic gens Lucretia, and his work shows an intimate knowledge of the luxurious lifestyle in Rome. Lucretius's love of the countryside invites speculation that he inhabited family-owned rural estates, as did many wealthy Roman families, and he certainly was expensively educated with a mastery of Latin, Greek, literature, and philosophy. Another note regarding Lucretius's biography found in Jerome's Chronicon, claims that Lucretius "was driven mad by a love potion, and when, during the intervals of his insanity, he had written a number of books, which were later emended by Cicero, he killed himself by his own hand in the 44th year of his life." The claim that he was driven mad by a love potion, although defended by such scholars as Reale and Catan, is often dismissed as the result of historical confusion, or anti-Epicurean bias. In some accounts the administration of the toxic aphrodisiac is attributed to his wife Lucilia. Regardless, Jerome's image of Lucretius as a lovesick, mad poet continued to have significant influence on modern scholarship until quite recently, although it now is accepted that such a report is inaccurate.

His poem De rerum natura (usually translated as "On the Nature of Things" or "On the Nature of the Universe") transmits the ideas of Epicureanism, which includes atomism and cosmology. Lucretius was the first writer known to introduce Roman readers to Epicurean philosophy. The poem, written in some 7,400 dactylic hexameters, is divided into six untitled books, and explores Epicurean physics through richly poetic language and metaphors. Lucretius presents the principles of atomism, the nature of the mind and soul, explanations of sensation and thought, the development of the world and its phenomena, and explains a variety of celestial and terrestrial phenomena. The universe described in the poem operates according to these physical principles, guided by fortuna, "chance", and not the divine intervention of the traditional Roman deities and the religious explanations of the natural world. Within this work, Lucretius makes reference to the cultural and technological development of humans in his use of available materials, tools, and weapons through prehistory to Lucretius's own time. He specifies the earliest weapons as hands, nails, and teeth. These were followed by stones, branches, and fire (once humans could kindle and control it). He then refers to "tough iron" and copper in that order, but goes on to say that copper was the primary means of tilling the soil and the basis of weaponry until, "by slow degrees", the iron sword became predominant (it still was in his day) and "the bronze sickle fell into disrepute" as iron ploughs were introduced. He had earlier envisaged a pre-technological, pre-literary kind of human whose life was lived "in the fashion of wild beasts roaming at large". From this beginning, he theorised, there followed the development in turn of crude huts, use and kindling of fire, clothing, language, family, and city-states. He believed that smelting of metal, and perhaps too, the firing of pottery, was discovered by accident: for example, the result of a forest fire. He does specify, however, that the use of copper followed the use of stones and branches and preceded the use of iron. Lucretius seems to equate copper with bronze, an alloy of copper and tin that has much greater resilience than copper; both copper and bronze were superseded by iron during his millennium (1000 BC to 1 BC). He may have considered bronze to be a stronger variety of copper and not necessarily a wholly individual material. Lucretius is believed to be the first to put forward a theory of the successive uses of first wood and stone, then copper and bronze, and finally iron. Although his theory lay dormant for many centuries, it was revived in the nineteenth century and he has been credited with originating the concept of the three-age system that was formalised from 1834 by C. J. Thomsen.
