The tale of the Trojan Horse is a pivotal story in Greek mythology, illustrating the cunning of the Greeks during the Trojan War. The Greeks, unable to breach the city of Troy, constructed a giant horse and hid soldiers inside. They left it at Troy's gates as a supposed peace offering, leading the Trojans to bring it into the city. At night, the soldiers emerged, opening the gates for the Greek army to invade. This story signifies the themes of deception, strategic warfare, and the idea that intelligence often triumphs over brute strength.
