A very common usage during the Middle Ages was to measure the sick person, at one time to cure him, at another to find out if the disease was decreasing or increasing. Another means was to drag him through a hole. Sick children were pulled through holes dug in the earth or through a cleft cherry-tree. Sick sheep were forced to creep through the cleft of an oak, and so on. Another remedy against many kinds of sufferings was the binding of a thread or a band which had been read over, around the neck or some limb of the sick. Connected with this is the tying of witch-knots, used only with evil intent. Bands of different colors and material[59] were required for these. They were buried near the dwelling of the person to be injured. It was thought that by this means any limb or bodily power of an enemy could be impaired. A French jurist and witch-judge, Pierre Delancre, complains that in his days there were few married couples in France whose happiness had not been marred by this means; young men hardly dared to marry from fear of it. Hincmar, archbishop of Rheims, advised, as a remedy against this influence, a diligent use of the sacraments. In French rituals church-prayers against the effects of witch-knots are prescribed. Hardly less universally was it the custom to make dolls of rags, dough, wax or clay, baptize them with the name of the hated person, put them in the fire or pierce them with needles, and bury them under the threshold of that individual, all in order to inflict sufferings on him.[60] Diseases could also be transferred to dolls by reading certain formulæ, and placing them in some inaccessible place, or in running water.
