In Cappadocia, a local vendor covered this old branch with evil eye beads. His shop sits on a hill above the village of Uçhisar castle, carved into the volcanic tuff of the region.
The glass evil eye beads I remember from my time in Turkey had yellow in them, unlike most of the ones we saw during this 2006 journey. Evil eye beads became talismans to conquer what ancient civilizations feared, such as nighttime dark, storms, earthquakes and eclipses.
The blue symbolizes the sky, the white is the aura of the moon, the yellow is the sun disc, and the black spot in the middle is that little bit of evil eating away at the light. They must be glass; they must be made in Turkey.
In Turkey, the talisman has evolved into a Ward against the effects of the Evil Eye, such as envy or jealousy, and bounce back any ill will or a curse. You will see an ubiquitous evil eye bead pinned to the clothing of an infant, hanging from the rear view mirror of a vehicle, decorating the harness of a horse, painted on the back of a big truck/lorry, placed over a doorway, anywhere it might serve as a ward. It is better if it is visible. If it breaks, throw it away; it has done its job!
