The Greeks believed in two myths known as the Iliad and the Odyssey. These myths were taught in schools, and were also used as examples of the type of life that a Greek citizen should strive to live.
Among the stories found in these myths is that of a giant wooden horse. In the myth of the Iliad, an army attempted to conquer the city of Troy. After ten years, they had still been unable to break through the Trojan’s defenses. In frustration, they devised a plot to get the Trojan’s to let them into their city.
It is only with the heart that one can see rightly; what is essential is invisible to the eye.
Antoine De Saint-Exupery
