Kukeri are carnival processions in which only men participate. The Kukeri king symbolically plows and sows his fields. The custom recreates the relationship between nature and man: the dying of winter symbolizes the killing of the King; the arrival of the spring - the resurrection of the King.
The movements of the kukeri have conjuring meanings: the bouncing is to make the corn grow tall; the rolling on the ground - to charge a man with the earth's strength; the clatter of the bells and cowbells - to scare and chase away evil spirits.
The most important attributes are the kukeri masks and costumes. Mandatory elements of the mask are mirror pieces , which reflect the evil spirits to be repelled and expelled. Tassels, flowers and beads are added. The green color in the mask is a symbol of the woods, the blue - of the sky and the white - of the water.
