 In the region of Bihor, north-eastern Montenegro, a round loaf of bread with a hole in its center was prepared; four grooves were impressed into its surface along two mutually perpendicular diameters of the loaf.After an ox was led into the house, the loaf was put on his horn, and some grain was thrown on the ox.Yanking his head, the ox would throw off the loaf; having fallen down, the loaf would break into four pieces along the grooves.
