Cardan, called by his contemporaries the greatest of men and the most foolish of children--Cardan, who first dared to criticise Galen, to exclude fire from the number of the elements, and to call witches and saints insane--this great Cardan was the son, cousin, and father of lunatics, and himself a lunatic all his life. “A stammerer, impotent, with little memory or knowledge,” he himself wrote, “I have suffered since childhood from hypno-fantastic hallucinations.” Sometimes it was a cock which spoke to him in a human voice; sometimes Tartarus, full of bones, which displayed itself before him. Whatever he imagined, he could see before him as a real object. From the age of nineteen to that of twenty-six, a genius, similar to one which already protected his father, gave him advice and revealed the future. When he had reached the age of twenty-six he was not altogether deprived of supernatural aid; a recipe which was not quite right forgot one day the laws of gravity, and rose to his table to warn him of the error he was about to commit.[165] He was hypochondriacal, and imagined he had contracted all the diseases that he read of: palpitation, sitophobia, diarrhœa, enuresis, podagra, hernia--all these diseases vanished without treatment, or with a prayer to the Virgin. Sometimes his flesh smelled of sulphur, of extinguished wax; sometimes he saw flames and phantoms appear in the midst of violent earthquakes, while his friends perceived nothing. Persecuted by every government, surrounded by a forest of enemies, whom he knew neither by name nor by sight, but who, as he believed, in order to afflict and dishonour him, had condemned his much-loved son, he ended by believing himself poisoned by the professors of the University of Pavia, who had invited him for this purpose. If he escapes from their hands, he owes it to the help of St. Martin and of the Virgin. Yet such a man in theology had audaciously anticipated Dupuis and Renan!
