One day, the Reimoeiro's daughter fell gravely ill and there was no cure for her ailment. Her father turned to all the wise men and healers in search of a solution, but without success. Feeling powerless, he grew impatient.
Then he heard that the Bugios, a neighboring people who lived in Sobrado, worshipped an image of São João Baptista that was famous for its miracles, including the healing of an illness that the daughter of the Velho da Bugiada himself had suffered. In desperation, he asked the Bugios to lend the image to intercede for his daughter's cure. The Bugios, in solidarity with the Reimoeiro, lent the image and São João performed another miracle. The girl was cured, to her father's joy.
In gratitude for the grace received, the Reimoeiro organized a feast, but refused to return the image to the Bugios. But the Reimoeiro's ingratitude went further — at the banquet he offered, as an affront, he gave the leftovers to the Bugios. They responded in kind. The die was cast.
