The Aeneid tells us that the Greeks, weary of their 10-year siege of Troy, built a huge wooden horse, filled it with their best warriors, and left it outside the city gates. The Trojans watched the rest of the Greek army withdraw. That night, they pulled the horse inside and celebrated what they thought was the end of the siege. When the Trojans were asleep, the Greek warriors emerged from the horse and opened the gates for their colleagues, who joined them in sacking the city, killing all the Trojan men, and enslaving their women and children.
