Evil eye is a curse, a ‘’look’’ or a ‘’stare’’ believed to be cast by a malevolent glare, most of the time given to a person when is unaware. Usually the reason is jealousy or envy of others. Many cultures believe that receiving evil eye will cause misfortune or injury. No one really knows this legend and believe when or where it started. But we know for sure it is a very old legend that to day many part of the world still believes and fallows this tradition.
It dates back at least to Greek classical antiquity, 6th century BC where it appeared on Chalcidian drinking vessels, known as 'eye-cups’, as a type of apotropaic magic.
Older iterations of the symbol were often made of ceramic or clay, however, following the production of glass beads in the Mediterranean region in approximately 1500 BC, evil eye beads were popularised with the Phoenicians, Persians, Greeks, Romans and Ottomans. Blue was likely used as it was relatively easy to create; however, modern evil eyes can be a range of colours.
