Cultures through history have used the eye as a symbol of knowledge, providence, foresight, power and divine direction and protection. The eyes as windows on the soul is a common idea. The spiritual associations move iconoclasts to behead statues; frescoe figures in abandoned Christian churches in Turkey have their eyes hacked out. Samson had his eyes put out by the Philistines.
