Whilst in the process of losing all his money, Cardano noticed that his opponent had marked the cards. Whereupon he leapt up, slashed his opponent across the face with his dagger and grabbed the money. Outwitting his host's spear-wielding servants, he fled into the night-shrouded maze of the streets, eventually falling into a canal. [Footnote: It is interesting to note that Cardano may well have been rector of the University of Padua at the time.]
