While reading A Distant Mirror, which leads into the miracle of Joan of Arc being at the end of the Hundred Years War, I decided to get out my copy of Marina Warner's Joan of Arc to compare Warner's view of the events of the war to that of Tuchman. One of the commands issued by Joan's voices was that Charles VII must go to Rheims, which was in enemy hands at the time, to be crowned King of France and anointed with the special oil which was kept at Rheims for the anointing of kings since the days of Clovis. The oil was given to the Bishop Remigius by the Holy Spirit in the form of a white dove, according to Hincmar, the archbishop of Rheims in the 9th century.
After he had been crowned in a bare bones ceremony, he touched the relics of the martyr, St. Marcoul, and "through his intercession heal the scrofula, or king's evil, of his subjects. Scrofula is a disfiguring, incurable disease of the skin, and the only remedy in medieval times was believed to be the touch of the legitimate, God-appointed and God-pleasing king." This according to Warner's notes comes from the chronicle of Enguerrand Monstrelet. By healing people, Charles VII was confirming for himself and his people that he was the rightful king.
Edward the Confessor, one of the last Anglo-Saxon kings of England, was the first to have been credited this power by Osbert de Clare and all subsequent kings of England are also supposed to have had this power to heal the King's Evil, as scrofula was called.
So the hands of the king really were healing hands, if you believe.
