Odysseus was the legendary Greek King of Ithaca and was well known for his intellectual brilliance. His idea to create the Trojan Horse helped the Greeks win the Trojan war. The war lasted for 10 years and ended when the Greeks pretended to withdraw, leaving behind a large wooden horse with hidden warriors inside. As Trojans considered horses to be sacred, they allowed it in and the Greeks opened the city gates to their comrades, at night. After the war, he spent 10 years trying to return home and reassert his place as rightful King of Ithaca. His journey is described in the famous Homer’s Odyssey, an epic poem about his adventures.
