From Egyptian Secrets of Albertus Magnus, Joseph H. Peterson edition:
For Gangrene of Man or Beast
Three lords are riding between two ladies. The first is called St. Luke, the other St. Mark, the third St. John. They hold forth their arm, bless that face so warm; extend their hands, bless the face so charmingly; they stretch out their thumbs, they bless Sodoma. + + + Three times, and the Lord's Prayer.
