He had not lived long in Bologna before he was fated to experience another repetition of one of the untoward episodes of his past life, to wit the fall of a house. It was not his own house this time, but it was sufficiently near to induce him to change his abode without delay. Next door to the house he had hired in the Via Gombru stood a palace belonging to a certain Gramigna. "The entire house fell, and was ruined in a single night, and together with the house perished the owner thereof." It was believed that this man had divers powerful enemies, and, in order that he might secure his position, he contrived to bring certain of his foes into his house, having first made a mine of gunpowder under the portico, and set a match thereto. But for some reason or other the plot miscarried the night when he destined to carry it out. Gramigna went to see what was amiss, and at that very moment the mine exploded and brought the house to the ground. After this explosion Cardan moved to a house in the Galera quarter, belonging to the family of Ranucci; but he did not find this dwelling perfect, as he was forced to vacate the rooms which were most to his taste on account of the bad state of the ceilings, the plaster of which, more than once, fell down upon his head. In his _Paralipomena_, "the last fruit off an old tree," which he put together about this time, there are numerous stories of prodigies and portents; of doors which would not close, and doors which opened of their own accord; of rappings on the walls, and of mysterious thunderings and noises during the night. He tells, at length, the story, already referred to, of the strange thing which happened to him, on the eve of his departure from Pavia in 1562, while he was awaiting tidings from Rome as to his appointment at Bologna. "I wore on the index finger of my right hand a selenite stone set in a ring, and on my left a jacinth, which I never took off my finger, this stone being large and hexagonal in shape. I took the selenite from my finger and put it beneath my pillow, for I fancied it kept off sleep, wearing still the jacinth because it appeared to have the opposite effect. I slept until midnight, when I awoke and missed the ring from my left hand. I called Jacopo Antonio, a boy of fifteen years of age who acted as my servant and slept in a truckle bed, and bade him look for my rings. He found the selenite at once where I had placed it; but though we both of us sought closely for the jacinth we could not find it. I was sorrowful to death on account of this omen, and despair seized upon my soul when I remembered the dire consequences of similar signs, all of which I had duly noted in my writings. I could scarcely believe this to be a thing happening in the order of nature. After a short delay I collected my thoughts, and told the servant to bring a light from the hearth. He replied that he would rather not do this, that he was afraid of the darkness, and that the fire was always extinguished
