This is a custom that can be seen only in some villages between Strandzha and the Black Sea, around Bourgas. It is observed on the holiday of St.Konstantin and Elena , and sometimes on some of the local village fairs and the church/patron saint's days. A basic element of the custom is the dance in fire ( glowing embers). The whole village takes part in the celebration but it is only the fire-dancers that participate in the ritual dance. They are chosen by the saint who is patron of the holiday. The dancers are able to "see" his face, to "hear" his voice and his spirit is transferred in them and on his behalf they can interpret omens , give advices and scorn people.
