Anything which came in contact with the saint was likely to have been impregnated with this magical quality, and thus became a charm, or relic, whose value depended primarily on the power of the man himself, and secondly, on the thoroughness with which the material had been charged. The tomb, which held the whole body, naturally stood highest; then parts of the body, according to their importance--a head, an arm, a leg, down to hairs of the beard. Then came hats, boots, girdles, cups, anything indeed which had been used. The very ground on which a great miracle-worker had stood might have high value. The Holy Grail, which had held Christ’s blood, would cure wounds, raise the dead, and fill itself with choice food, at the command of the owner. The eucharist, though not properly a relic, and which only became God through an incantation, would, in expert hands, stop fires, cure disease, cast out devils, expound philosophy, and detect perjury by choking the liar. Every prize in life was to be obtained by this kind of magic. When the kings of France made war, they carried with them the enchanted banner of Saint Denis, and Froissart has told how even in the reign of Charles VI. it decided the battle of Roosebeke.[83] Disease was treated altogether by miracle, and the Church found the business so profitable that she anathematized experimental practitioners. In the thirteenth century Saint Thomas of Canterbury and Saint James of Compostello were among the most renowned of healers, and their shrines blazed with the gifts of the greatest and richest persons of Europe. When Philip Augustus lay very ill, Louis the Pious obtained leave to visit the tomb of Saint Thomas, then in the height of the fashion, and left as part of his fee the famous regal of France, a jewel so magnificent that three centuries and a half later Henry VIII. seized it and set it in a thumb ring. Beside this wonderful gem, at the pillage of the Reformation, “the king’s receiver confessed that the gold and silver and precious stones and sacred vestments taken away ... filled six-and-twenty carts.”[84] The old books of travel are filled with accounts of this marvellous shrine. “But the magnificence of the tomb of Saint Thomas the Martyr, Archbishop of Canterbury, is that which surpasses all belief. This, notwithstanding its great size, is entirely covered with plates of pure gold; but the gold is scarcely visible from the variety of precious stones with which it is studded, such as sapphires, diamonds, rubies, balas-rubies, and emeralds ... and agates, jaspers and cornelians set in relievo, some of the cameos being of such a size, that I do not dare to mention it; but everything is left far behind by a ruby, not larger than a man’s thumb-nail, which is set to the right of the altar.... They say that it was the gift of a king of France.”[85]
