The evil eye is a look that is believed by many cultures to be able to cause injury or bad luck for the person at whom it is directed for reasons of envy or dislike. The term also refers to the power attributed to certain persons of inflicting injury or bad luck by such an envious or ill-wishing look.
Attempts to ward off the curse of the evil eye has resulted in a number of talismans in many cultures. As a class, they are called "apotropaic" (Greek for "prophylactic" or "protective," literally: "turns away") talismans, meaning that they turn away or turn back harm.
The Hamsa, a charm made to ward off the evil eye. Disks or balls, consisting of concentric blue and white circles (usually, from inside to outside, dark blue, light blue, white, dark blue) representing an evil eye are common apotropaic talismans in the Middle East, found on the prows of Mediterranean boats and elsewhere; in some forms of the folklore, the staring eyes are supposed to bend the malicious gaze back to the sorcerer.
Known as nazar (Turkish: nazar boncuğu or nazarlık), this talisman is most frequently seen in Turkey, found in or on houses and vehicles or worn as beads. A blue eye can also be found on some forms of the hamsa hand, an apotropaic hand-shaped talisman against the evil eye found in the Middle East. The word hamsa, also spelled khamsa and hamesh, means "five" referring to the fingers of the hand. In Jewish culture, the hamsa is called the Hand of Miriam; in some Muslim populated cultures, the Hand of Fatima. However, it is considered a superstition to practicing or religious Muslims that any symbol or object protects against the evil eye. In Islam, only God can protect against the evil eye.
