"Prahara, dan kilat cerah, harus dinyanyikan; sifat mereka harus diberi tahu, dan dari sebab apa mereka mengejar tujuan mereka; jangan sampai, memiliki bodoh dibagi langit menjadi bagian-bagian, Anda harus cemas untuk kuartal dari mana api terbang mungkin datang, atau apa wilayah mungkin pergi sendiri; dan gemetar memikirkan bagaimana menembus melalui kandang berdinding, dan bagaimana, setelah memegang kekuasaan, ia extricates diri dari mereka. Dari mana fenomena kaleng banyak tidak berarti melihat penyebab, dan berpikir bahwa mereka dicapai dengan kekuatan supranatural."

--- Lucretius

Versi Bahasa Inggris

Tempests, and bright lightnings, are to be sung; their nature is to be told, and from what cause they pursue their course; lest, having foolishly divided the heaven into parts, you should be anxious as to the quarter from which the flying flame may come, or to what region it may betake itself; and tremble to think how it penetrates through walled enclosures, and how, having exercised its power, it extricates itself from them. Of which phenomena the multitude can by no means see the causes, and think that they are accomplished by supernatural power.
