When the boy was of age, the godfather walked in one day, told him to come along, and led him out into the woods. He showed him an herb which grew there and said, “This is your christening gift. I shall make you into a famous doctor. When you are called to a patient’s bedside I will appear and if I stand at the sick man’s head you can boldly say that you will cure him and if you give him some of this herb he will recover. But if I stand at the sick man’s feet, then he is mine, and you must say there is no help for him and no doctor on this earth could save him. But take care not to use the herb against my will or it could be the worse for you.”
