Evil Eye, a superstitious belief that certain people have the power of exercising a baneful influence on others, and even animals, by the glance of the eyes. The superstition is of ancient date, and is met with among almost all races, as it is among illiterate people and savages still. It was customary to wear amulets toward the evil off.
