The Survival of the Frater Medicus? English Friars and Alchemy, ca. 1370-ca. 1425
1a King's College, University of Cambridge , UK.
Abstract:
This essay reinserts friars into the story of alchemy and medicine in late medieval England. Much of the evidence for the activity of friars, mostly Franciscans, is to be found in a Latin text compiled in 1416-1425, the Tabula medicine. Here friars appear as sources for remedies, and a significant number of these remedies are alchemical. The quintessence found in the writings of John of Rupescissa is used for a variety of medical complaints. Some of the alchemical remedies are selected for closer examination here. These include distillations of human blood which are recommended by brother Robert Winstanton for use in surgery, either to knit flesh together or to cut through it. Natural balsam was in very short supply in Western Europe, though it served as a panacea for multiple ailments. The friars offer a number of different recipes to make artificial balsam, ranging from comparatively simple distillations through to the use of multiple fractional distillations to produce the finest of all balsams. The friars found that distilled waters made with herbs were more effective than herbal simples without distillation in the treatment of many different complaints.
