Margaret and the other friends of the king used to contrive various other ways of amusing and comforting his mind, some of which were not very honest. One was, for example, to have different nobles and gentlemen come to him and ask his permission that they should leave the kingdom to go and make pilgrimages to various foreign shrines, in order to fulfill vows and offer oblations and prayers for the restoration of his majesty's health. The king was of a very devout frame of mind, and his thoughts were accustomed to dwell a great deal on religious subjects, and especially on the performance of the rites and ceremonies customary in those days, and it seemed to comfort him very much to imagine that his friends were going to make such long pilgrimages to pray for him. So the nobles and other great personages would ask his consent that they might go, and would take solemn leave of him as if they were really going, and then would keep out of sight a little while, until the poor patient had forgotten their request. [Sidenote: One real pilgrimage.] It is said, however, that one nobleman, the Duke of Norfolk, who was so kind-hearted a man that he went by the name of the Good Duke, actually made the pilgrimage to Jerusalem on this errand, and there offered up prayers and supplications at the famous chapel of the Holy Sepulchre for the restoration of his sovereign's health. [Sidenote: The philosopher's stone.] [Sidenote: Promised treasures.] They used also to amuse and cheer the king's mind by telling him, from time to time, that he was going to be supplied with inexhaustible treasures of wealth by the discovery of the philosopher's stone. The philosopher's stone was an imaginary substance which the alchemists of those days were all the time attempting to discover, by means of which lead and iron, and all other metals, could be turned to gold. There were royal laboratories, and alchemists continually at work in them making experiments, and the queen used to give the king wonderful accounts of the progress which they were making, and tell him that the discovery was nearly completed, and that very soon he would have in his exchequer just as much money as his heart could desire. The poor king fully believed all these stories, and was extremely pleased and gratified to hear them. [Sidenote: Intervals of good health.]
