Finally, de Bourgogne wrote under his own name a treatise on the plague, extant in Latin, French and English texts, and in Latin and English abridgments. Herein he describes himself as Johannes de Burgundia, otherwise called cum Barba, citizen of Liège and professor of the art of medicine; says that he had practised forty years and had been in Liège in the plague of 1365; and adds that he had previously written a treatise on the cause of the plague, according to the indications of astrology (beginning "Deus deorum"), and another on distinguishing pestilential diseases (beginning "Cum nimium propter instans tempus epidimiate"). "Burgundia" is sometimes corrupted into "Burdegalia", and in English translations of the abridgment almost always appears as "Burdews" (Bordeaux, France) or the like manuscript "Rawlinson D. 251" (15th century) in the Bodleian Library also contains a large number of English medical receipts, headed "Practica phisicalia Magistri Johannis de Burgundia".
