Virgil’s Aeneid

A Trojan guest and a story about Hercules

Virgil’s Aeneid is a Roman epic: a long heroic narrative involving human struggles, divine powers and the origins of a community. Written from around 29 BC until Virgil’s death in 19 BC, it follows Aeneas, a Trojan prince who escapes the destruction of Troy and travels to Italy. His descendants will eventually found Rome; Aeneas does not found Rome himself.

The prescribed passage, Book 8, lines 154–279, brings together two stories. In the present action, King Evander welcomes Aeneas and agrees to help him. Within that encounter, Evander tells how Hercules defeated Cacus. His story explains why the community holds an annual festival in Hercules’s honour. The passage therefore connects hospitality and alliance with the remembrance of a divine benefactor.

Evander’s welcome: friendship across generations

Evander recognises in Aeneas the voice and appearance of his father, Anchises. He remembers meeting Anchises when Trojan leaders visited Arcadia during Evander’s youth. Although he admired Priam and the other Trojans, Anchises impressed him most: Evander recalls his height and his own eagerness to approach him and clasp his hand.

This is more than a pleasant memory. It gives Evander’s welcome a personal foundation. Anchises had given him a quiver of Lycian arrows, a gold-woven cloak and golden horse bits, which Evander’s Pallas now owns. These lasting gifts link the older friendship to the next generation. Evander agrees to the alliance Aeneas seeks and promises help and supplies the following morning.

His hospitality turns those words into actions. He personally seats the warriors on turf benches and gives Aeneas the principal guest’s place: a maple-wood throne covered with a lion’s pelt. The combination of simple seating and special treatment suggests a welcome that is generous without depending on magnificent surroundings. The lion’s pelt also suits a scene centred on Hercules’s heroic exploits.

A sacred meal, not merely a feast

Evander invites the Trojans to join an annual festival which, he says, it would be wrong to delay. Religious observance therefore has its own claim on the community, even while Evander is receiving important visitors.

The meal is explicitly connected with sacrifice. An altar priest and chosen young men serve roasted bull meat, bread and wine. Aeneas and the Trojans eat beef and sacrificial organs. Worship here includes communal eating: the guests participate in the community’s religious life as well as receiving its hospitality.

After the meal, Evander explains the celebration. He rejects the idea that the rites arose from “idle superstition” or ignorance. Instead, he says they repeat the honours owed because the people were saved from “cruel perils”. His speech presents worship as grateful remembrance of help received. To explain that gratitude, he points to a shattered cliff and deserted cave, making the landscape a visible reminder of the story he is about to tell.

Cacus: terrifying, cruel and cunning

Cacus inhabits a deep cave untouched by sunlight. The ground is warm with fresh blood, and decaying human heads hang nailed to its doors. These details establish him as a threat to human life before he steals anything from Hercules. Darkness conceals his violence, while the displayed heads make that violence deliberately intimidating.

He is half-human, massively built and able to belch fire. Vulcan is his father, but divine parentage does not make Cacus morally good. His monstrous appearance and actions distinguish him from the human community outside his cave.

Hercules arrives driving the cattle he has taken from the three-fold Geryon. Cacus steals four bulls and four heifers, choosing outstanding animals. He drags them backwards into his cave by their tails so that their tracks do not lead towards it. This detail characterises him through cunning as well as brute force: he anticipates pursuit and tries to disguise his crime.

Yet his plan fails through sound rather than tracks. As Hercules prepares to leave, his herd lows, and a captive heifer answers from inside the cave. Her call reveals where the stolen animals are hidden. Cacus can manipulate the apparent evidence on the ground, but cannot completely silence his victims.

Hercules’s victory: strength, persistence and rage

Hercules responds with intense anger. He takes up his weapons and heavy knotted club and rushes towards the mountain. Cacus, previously terrifying to the people, is now afraid. He flees to his cave and blocks its entrance with a giant rock suspended by chains made through his father’s skill.

Hercules is powerful, but the barrier initially defeats him. Three times he circles the Aventine Hill, three times he tries the doorway, and three times he sinks down exhausted. This sequence delays the victory and makes the obstacle substantial. His eventual success requires persistence and a different approach, not one effortless blow.

He tears away a pinnacle of rock behind the cave, exposing its interior from above. He then showers Cacus with missiles, branches and huge stones. Cacus responds by filling the cave with smoke, darkness and fire. Hercules leaps into the thickest smoke and flames, seizes him in a tight clasp and chokes him to death. Afterwards, the cave is opened, the stolen cattle are revealed and Cacus’s body is dragged out for the people to examine.

Evander calls Hercules “the greatest of avengers” and presents his arrival as the assistance of a god. Hercules removes a murderous threat and restores the cattle. Nevertheless, the description of his “venomous dark rage”, gnashing teeth and tearing passion complicates the heroic picture. His violence achieves deliverance, but Virgil also makes its frightening intensity visible. The passage allows admiration for his courage and achievement alongside unease about his fury.

How the telling makes the struggle vivid

The repeated “three times” creates a strong pattern in Hercules’s unsuccessful attempts. This is anaphora, repetition at the beginnings of successive clauses. It emphasises the effort involved and builds anticipation before he discovers another way into the cave.

When Hercules tears away the rock, the heavens thunder, the banks break apart and the “terrified river” recoils. Giving the river fear is personification. The landscape seems to react to Hercules’s extraordinary strength, making the struggle feel larger than an ordinary fight.

An extended comparison likens the exposed cave to the earth opening to reveal the underworld, with its spirits trembling at incoming light. This epic simile connects depth, darkness and sudden exposure. It makes Cacus’s home seem a dreadful realm rather than simply a hiding place.

Light and darkness also organise the action. Cacus conceals stolen cattle in darkness; Hercules exposes the cave to daylight; Cacus creates fresh darkness with smoke; finally, his theft is revealed “to the heavens”. This pattern connects physical exposure with the discovery of wrongdoing. These are features that can be explored in the English translation without needing to reconstruct the poem’s Latin sound or metre.

From rescue to continuing worship

The ending returns from Hercules’s struggle to Evander’s festival. The tale is an aetiology: it explains the origin of a religious practice. Evander says the rite preserves the memory of the community’s rescue for later generations.

Potitius is named as the first founder, with the Pinarian House as guardians of Hercules’s worship. They established the altar in the grove, called “The Mightiest”. Naming its founders and guardians gives the celebration continuity: a single heroic act has become an organised, inherited religious observance.

Evander then invites the young men to crown themselves with leaves, hold wine-cups in their right hands, call upon the god and pour out wine. He himself wears grey-green poplar leaves and holds a sacred cup. Everyone pours a joyful libation, an offering of liquid, and prays to the gods.

The passage ends with people performing the worship whose meaning Evander has just explained. Hercules’s rescue, the altar, the annual festival and the shared meal form one connected account of communal gratitude. As a literary myth, it reveals how divine protection could be understood and commemorated; it is not proof that the battle with Cacus historically occurred.
