Dear colleagues, I would be very grateful for some advice on a phrase or tag which I keep coming across. I'm reading thirteenth-century Parisian disputations concerning usurious money and indeed I'm trying to finish an article on the subject. One loose end refuses to tied up! The masters of Paris are discussing whether or not the obligation to make restitution passes to others when they come into possession of money which a usurer has taken in usury. When it is argued that the obligation does pass with the money or with other forms of usurious property, they often conclude with the phrase: res transit cum onere suo, or something very close. It seems to be an authority, but it is not identified in editions where it occurs and I have not been able to track it down. Any suggestions would be wonderful!
