 The traditional notion that the long illness is a punishment for a grave sin is found in a number of variants.In a Macedonian version, a group of heroes, including Dojčin and Prince Marko, assembled at the Gračanica Monastery in Kosovo.Dojčin jumped over the monastery's church, disregarding Marko's warning not to do that, for which he was cursed by Saints Nicholas, Petka, and Catherine.
