The Book of Dreams and Ghosts

THE COLD HAND [Jerome Cardan, the famous physician, tells the following anecdote in his De Rerum Varietate, lib. x., 93. Jerome only once heard a rapping himself, at the time of the death of a friend at a distance. He was in a terrible fright, and dared not leave his room all day.] A story which my father used often to tell: "I was brought up," he said, "in the house of Joannes Resta, and therein taught Latin to his three sons; when I left them I supported myself on my own means. It chanced that one of these lads, while I was studying medicine, fell deadly sick, he being now a young man grown, and I was called in to be with the youth, partly for my knowledge of medicine, partly for old friendship's sake. The master of the house happened to be absent; the patient slept in an upper chamber, one of his brothers and I in a lower room, the third brother, Isidore, was not at home. Each of the rooms was next to a turret; turrets being common in that city. When we went to bed on the first night of my visit, I heard a constant knocking on the wall of the room. "'What is that?' I said. "'Don't be afraid, it is only a familiar spirit,' said my companion. 'They call them follets; it is harmless enough, and seldom so troublesome as it is now: I don't know what can be the matter with it.'
