The Trojan Horse is the legendary device the Greeks used to finally end their decade-long siege of Troy, according to ancient Greek and Roman mythology. Unable to breach the city's walls by force, the Greek warrior Odysseus supposedly devised a plan: build a massive hollow wooden horse, hide a select group of soldiers inside it, and leave it outside Troy's gates as an apparent peace offering while the rest of the Greek fleet sailed away, pretending to abandon the siege.
Believing the war finally over and the horse a gift to the gods, the Trojans dragged it inside their own walls to celebrate, ignoring warnings from the priest Laocoön and the prophetess Cassandra, both of whom insisted the horse was a trick. That night, the hidden Greek soldiers climbed out, opened the city gates for their returning army, and Troy fell.
A Gift the Trojans Couldn't Resist
A Story Homer Never Actually Told in Full
Oddly, Homer's Iliad, the primary surviving epic about the Trojan War, ends before the horse ever appears — it stops with the death of the Trojan hero Hector. The fullest ancient account of the horse itself actually comes from the Roman poet Virgil's Aeneid, written centuries later, along with briefer references in Homer's own Odyssey and other now-lost Greek epic poems.
Archaeologists have never found physical evidence of an actual wooden horse, and most historians treat the story as legend layered onto whatever real conflict inspired the broader Trojan War myth. The phrase "Trojan horse" has nonetheless outlived the literal story, surviving today as shorthand for any trick, gift, or piece of malicious software that hides a threat inside something that looks harmless.
