“One reads in the Story of Saint Martial, apostle of the Gaul, and particularly of Aquitaine and Limousin, by R. Bonaventure of Saint-Amable, the barefoot monk, part 3, p. 752:
"In the year 1518, in the month of December, in the house of Pierre Juge, a merchant of Limoges, a Spirit made a great noise for a fortnight, knocking on doors, planks and paving stones, moving utensils from one place to another. Several monks went there to give mass, and to watch the night with lighted candles and holy water, but the Spirit did not speak. A sixteen year old young man, native of Ussel, who served this merchant, confessed that the Spirit had often molested him at home and in several other places, and added that his relative, who had left him heir, had died in the war, and had often appeared to several of his parents, and had spanked his sister, who died three days later. The aforesaid merchant Juge released this young man and all that noise ceased."
Evidently the young man was an unconscious medium of physical effects as there has always been. The knowledge of the laws that govern the relationships between the visible and invisible worlds brings all those supposedly wonderful facts to the domain of natural laws.
