The evil eye is believe to protect against evil forces (jealousy, pure malice and envy).
The evil eye - first recorded by the Mesopotamian about 5,000 years ago in cuneiform on clay tablets, the Evil Eye may actually have originated as early as the Upper Paleolithic age. We find this figure in Jewish, Christian and Muslim cultures as well as Buddhist and Hindu societies. The evil eye is a curse believed to be cast by a malevolent glare, which is usually directed towards a person who is unaware. Many cultures believe that receiving the evil eye will cause one misfortune, bad luck or injury. Talismans created to protect against the evil eye are also frequently called "evil eyes"
The evil eye is a look given to inflict harm, suffering, or some form of bad luck on the person that it is cast upon. Giving someone “the evil eye” is a look which clearly states that one intends for something bad to happen to the other person, either out of jealousy or pure malice. It is believed by many cultures that the look is powerful enough to bring about actual disaster for the unfortunate person that is the receiver of the glare.
In many cultures, excessive praise or receiving admiration beyond what is truly deserved can bring upon the scorn of the evil eye, which was believed to cause physical and mental illness. Ashkenazi Jews believe that excessive praise causes a vulnerability to the evil eye, and will repeat a Yiddish phrase, “Keyn aynhoreh!” meaning “no evil eye” in order to protect against it.
The evil eye is a popular trend in jewelry today and can be seen on many celebrities as a stylish jewelry statement.
