Physicians of Myddvai. The domestic physician of Rhys Gryg, prince of South Wales, who died 1233, made a collection of recipes used in medicine at that date in his country. He was assisted by his three sons, the collection being a valuable historical record concerning remedial agents and methods of that date. Of these, two compilations have been issued, the two appearing together, 1861, with a translation by John Pughe (470 pp). The original manuscript is in the British Museum.
