What literary form is Lucretius' "De Rerum Natura" written in?

Lucretius' "De Rerum Natura" is composed in the form of an epic poem, specifically a philosophical epic. This literary form is characterized by its elevated language, grand themes, and the exploration of profound concepts. In "De Rerum Natura," Lucretius presents the principles of Epicureanism, discussing the nature of the universe, the atomic theory, and the pursuit of tranquility through understanding the world around us. As an epic poem, it aims to educate and inspire, using verse to convey complex philosophical ideas in a structured and poetic manner.

The other options represent different literary forms with distinct characteristics that do not align with Lucretius' work. Tragedy and comedy are dramatic forms focused on performance, while satire typically critiques societal norms and human behavior through humor and irony. Lucretius' philosophical exploration does not fit within those frameworks, reinforcing the classification of his work as an epic poem.
