Trojan Horse Meaning and Origin | The Odyssey, the Trojan Horse, Odysseus, Sinon, and the Fall of Troy Explained

One morning, the Greek army that had battered the city walls for ten years vanished without a trace. When the Trojans opened the gates and went out to look, all that remained was the site of an abandoned camp—and, standing in the middle of it, a single enormous horse made of wood.

This scene is handed down in Book 2 of Virgil's Aeneid, while Book 8 of Homer's Odyssey brings the same horse back to life in a completely different setting. Let's follow the two works separately, tracing how far each one goes and where each one stops.

Laocoön's Warning: The Spear Driven into the Horse

The priest Laocoön confronts this mood head-on. Shouting that the Greeks cannot truly have left—that this is the work of Odysseus's cunning, which they fail to grasp—he hurls a spear with all his strength into the flank of the horse. The spear pierces the wooden planks and lodges, quivering, in the horse's hollow belly; from the pierced flank comes a sound as if the empty body were groaning, and through the gap the moans of the soldiers trapped inside seep out.

The Man Who Pretended to Be Abandoned: Sinon's Lie

Even after Laocoön's cry, the unrest surrounding the horse would not settle. At that moment, a Greek captured by shepherds is dragged forward. This man, Sinon, claims that he had been marked for death by Odysseus's scheme and barely escaped. Bringing up first how his kinsman Palamedes was framed and put to death, he pleads through tears that this time Odysseus has singled him out as a sacrifice to be offered to the gods.

He then invents a plausible story about the horse's true nature. He says the Greeks built and dedicated this horse as penance for rashly tampering with the sacred image of the goddess Athena, and that they deliberately made it so enormous to keep the Trojans from being able to bring it inside their gates. He even adds that if the Trojans were to drag this horse into the city of Troy and offer it to Athena, that power would instead turn to Troy's side and Greece would fall.

A single false tear and a fabricated tale accomplished what ten years of siege and a thousand ships could not. The Trojans begin to waver at his words.

Two Serpents Arrive Late from the Sea: Laocoön Punished

At the very moment Sinon's words have nearly turned the Trojans' hearts, two enormous serpents come swimming side by side from the direction of the sea.

The serpents first coil around Laocoön's two sons and bite at them, and then, when the father rushes in to save his sons, they wind around his waist and neck, coil upon coil. Once all three have breathed their last, the serpents glide away and creep beneath the altar of Athena's temple, curling up their bodies.

Watching this scene before their eyes, the Trojans reach an entirely different conclusion: that Laocoön was punished for the crime of throwing a spear at the sacred horse. Having seen the man who threw the spear punished, no one now dared lay a hand on the horse.

A Horse Taken In at the Cost of Tearing Down the Walls: Cassandra's Ignored Warning

Mingled with fear and awe, the Trojans decide to bring the horse inside the city. But the horse was larger than the gates and could not pass through as it was. The people tear down a section of the city wall outright, fit wheels beneath the horse's feet, and drag it in with ropes.

In the midst of all this, the prophetess Cassandra steps forward and cries out in warning that disaster hides within it. But because of Apollo's curse, her prophecies, as always, win no one's belief. The people instead decorate the temples with laurel branches and celebrate their victory with feasting late into the night.

After Laocoön's spear and now Cassandra's warning, they laughed off a second warning and tore down their own walls to let the enemy in. The carelessness of that evening would decide the outcome of that night.

Night Falls Open, and Troy's End Begins

While the Trojans, worn out from the festival, lie in deep sleep, the Greek fleet that had earlier withdrawn beyond the walls quietly turns its prows and draws near the shore again. Sinon, who had been waiting for the signal, secretly opens the hatch on the horse's belly.

The Greek soldiers hidden inside slide down the ropes one by one. They run straight to the gates and undo the bars, letting the waiting Greek main force pour into the city.

The Trojan soldiers, defenseless with wine and sleep, are cut down without even mounting a proper resistance. The young warrior Pyrrhus pushes his way into King Priam's palace and cuts down the aged king right upon his altar. The city that had held out for ten years is engulfed in flames in a single night.

Book 8 of the Odyssey: The Same Horse, Sung Again at a Banquet

Homer brings out the story of the same horse in a completely different setting. One evening while Odysseus is staying as a guest at the palace of the Phaeacian king, the blind bard Demodocus strikes his lyre and begins to sing the song of the fall of Troy.

According to this song, the horse was built by Epeius, with the goddess Athena helping with the work. Odysseus is sung as the one who devised the stratagem and had this horse, carrying the warriors inside, brought into the city. While the horse stood within the city, the Trojans are said to have split three ways, arguing over whether they should smash it, drag it to the top of a cliff and hurl it down, or leave it standing as an offering to the gods.

Before any decision is reached, the song continues, the warriors hidden inside leap out from their ambush and sweep through the city. Odysseus and Menelaus fight side by side, pushing their way to the house of Deiphobos, where the fiercest fighting takes place.

Hearing this song, Odysseus cannot hold back his tears. Homer likens those tears to the weeping of a woman who, watching her city fall, collapses weeping over her husband's body before finally being dragged away as a captive by the enemy. A merry song at a banquet was, for the man who had lived through those events, like being dragged back onto the battlefield all over again.
