Lucan's Pharsalia, also known as the Bellum Civile, is a Roman epic poem written by the poet Lucan in the 1st century AD. The poem details the civil war between Julius Caesar and Pompey, presenting a vivid and dramatic portrayal of the conflict, as well as themes of fate, free will, and the moral implications of war. Unlike traditional epics that glorify heroism, Pharsalia adopts a darker tone, emphasizing the destructive nature of civil strife and the futility of human ambition.
