In the _Norma Vitae Consarcinata_[246] he relates how in April 1576 there were two inmates of the Xenodochium at Rome, Troilus and Dominicus. It seemed that Troilus exercised some strange and malefic influence over his companion, who was taken with fever. He got well of this, but only to fall into a dropsy, which despatched him in a week. Shortly before his death, at the seventh hour, he cried out to two Spaniards who were standing by the bed that he had suffered such great torture from the working of Troilus, and that he was dying therefrom. "Therefore," he cried, "in your presence I summon him with my dying words to appear before God's tribunal, that he may give an account of all the evil he has wrought against me." On the following day there came a messenger from Corneto, a few miles from Rome, saying that Troilus, who was sojourning there, had fallen sick. The physician inquired at what hour, and the messenger said it was at seven o'clock, a day or two ago. He lay ill some days, an unfavourable case, but not a desperate one, and one night shortly afterwards at seven o'clock, the top of the mosquito curtains fell, and he died at exactly the same hour as Dominicus. He tells another long story of an adventure which befell him in May 1576. One day he was driving in his carriage in the Forum, when he remembered that he wanted to see a certain jeweller who lived in a narrow alley close by. Wherefore he told his coachman, a stupid fellow, to go to the Campo Altoviti, and await him there. The coachman drove off apparently understanding the order; but, instead of going to the place designated, went somewhere else; so Cardan, when he set about to find his carriage, sought in vain. He had a notion that the man had gone to a spot near the citadel, so he walked thither, encumbered with the thick garments he had put on as necessary for riding in the carriage. Just then he met a friend of his, Vincenzio, a Bolognese musician, who remarked that Cardan was not in his carriage as usual. The old man went on towards the citadel, but saw nothing of the carriage; and now he began to be seriously troubled, for there was naught else to be done but to go back over the bridge, and he was wearied with long fasting and his heavy clothes. He might indeed have asked for the loan of a carriage from the Governor of the castle; but he was unwilling to do this, so having commended himself to God, he resolved to use all his patience and prudence in finding his way back. He set out, and when he had crossed the bridge, he entered the banking-house of the Altoviti to inquire as to the alteration in the rate of exchange on Naples, and there sat down to rest. While the banker was giving him this information, the Governor entered the place, whereupon Cardan went out and there he found his carriage, the driver having been informed by Vincenzio, whom he had met, of the mistake he had made. Cardan got into the carriage,
