In the district of Acquapendente three boys were watching cattle, and one of them said, "Let us find out the way in which people are hanged." While one was sitting on the shoulders of the other, and the third, after fastening the rope round the neck of the first, was tying it to an oak, a wolf came, and the two who were free ran away and left the other hanging. Afterwards they found him dead, and buried him. On the Sunday his father came to bring him bread, and one of the two confessed what had happened, and showed him the grave. The old man then killed him with a knife, cut him up, brought away the liver, and entertained the boy's father with it at home. After dinner, he told him whose liver it was. Hereupon began a series of reciprocal murders between the two families, and within a month 36 persons were killed, women as well as men.
