It remains unclear just what caused the death of Robert, a month before his fifty-fifth birthday. Contemporary accusations that Robert had leprosy, the "unclean sickness" – the present-day, treatable Hansen's disease – derived from English and Hainault chroniclers. None of the Scottish accounts of his death hint at leprosy. Penman states that it is very difficult to accept the notion of Robert as a functioning king serving in war, performing face-to-face acts of lordship, holding parliament and court, travelling widely and fathering several children, all while displaying the infectious symptoms of a leper. Along with suggestions of eczema, tuberculosis, syphilis, motor neurone disease, cancer or stroke, a diet of rich court food has also been suggested as a possible contributory factor in Robert's death. His Milanese physician, Maino De Maineri, did criticise the king's eating of eels as dangerous to his health in advancing years.
