In Greek mythology, the Trojan Horse was a wooden horse said to have been used by the Greeks during the Trojan War to enter the city of Troy and win the war. The Trojan Horse is not mentioned in Homer's Iliad, with the poem ending before the war is concluded, and it is only briefly mentioned in the Odyssey. But in the Aeneid by Virgil, after a fruitless 10-year siege, the Greeks constructed a huge wooden horse at the behest of Odysseus, and hid a select force of men inside, including Odysseus himself. The Greeks pretended to sail away, and the Trojans pulled the horse into their city as a victory trophy. That night, the Greek force crept out of the horse and opened the gates for the rest of the Greek army, which had sailed back under the cover of darkness. The Greeks entered and destroyed the city, ending the war.
