The first epic simile in the Aeneid is not just a way to poetically describe Neptune and his authority in action. It is also a means by which the poet can comment on contemporary politics in Rome.
The most striking evidence of political commentary is Vergil’s description of the man controlling the mob. “Tum, pietate gravem ac meritis si forte virum conspexere,” (Aeneid I.151-152). Vergil describes this person by calling him a man of great piety and merits. They fit someone legendary, not ordinary. In these few words Vergil could be implying that a Roman emperor can masterfully control the people. Is the emperor Augustus, and is Vergil praising him? The reaction of the angry crowd to this man as awe inspiring. “Silent arrectisque auribus astant; ille regit dictis animos et pectora mulcet,””(Aeneid I.152-153). An animalistic instinct stops the people in their tracks. The sheep-like response to the man’s words and presence indicates that this is no random man, but one who is instantly recognized and ultimately trusted. A Roman emperor meets these requirements and would be worthy of comparison to a god such as Neptune, even outside of an epic simile.
