The evil eye (Turkish: Nazar, Greek: μάτι, mati, "eye"; Hebrew: עַיִן הָרָע‎; Arabic: عين‎, ayn; Persian: چشم‎ cheshm) is a superstitious curse or legend, believed to be cast by a malevolent glare, usually given to a person when one is unaware. 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. Many cultures believe that receiving the evil eye will cause misfortune or injury, while others believe it to be a kind of supernatural force that casts or reflects a malevolent gaze back-upon those who wish harm upon others (especially innocents).
