The "Wooden Horse," also known as the Trojan Horse, is a famous tale from ancient Greek mythology. It was a large wooden structure used by the Greeks to deceive the city of Troy during the Trojan War. The Greeks hid soldiers inside the horse and left it at the gates of Troy as a supposed offering of peace. The Trojans brought the horse into their city, believing they had won the war. At night, the Greek soldiers emerged from the horse, opened the city gates for their comrades, and ultimately led to the fall of Troy. This story symbolizes cunning and deception in warfare.
