The paper presents the results of field research of a Serbian custom Pročka (White Shrovetide, the Eve of Lent) or The Wedding of Marko Kraljević, which is performed on Bela nedelja (White Shrovetide) in the Sirinić district (Šar Mountains region). Research was conducted in 2016, when two collocutors were interviewed: Cveta Stojanović (b. 1930, Bitinja, living in Jažinac) and Father Siniša Milenković. The elements of the custom are presented: masking, making and burning kumbara (a bundle of dried bark attached to the top of a stick and ignited), setting ritual fire in the village, as well as the lyrics of the folk songs.
