There is a legend which relates the following incident of Godfrey the Rough, Count of Barcelona. After he had fought by the side of Louis the Pious, with great courage and success, against the Saracens, he carried his gilded shield to the king, that he might receive permission to have an escutcheon placed thereon. As the king beheld him covered with wounds, from which the blood still gushed forth, he dipped his five fingers in the blood of the gallant warrior, and without saying a word, ran them over the shield, and thus marked five red lines upon it, which henceforth became the escutcheon of the Counts of Barcelona.
