The first printed medical book of an Englishman. John of Gaddesden was a prebendary of St. Paul’s Cathedral and physician to Edward II. The work, to quote Garrison, “consists mainly of Arabist quackeries and countryside superstitions”; it was compiled about 1314. For information regarding the various printed editions, see the article by Dock in Janus (Amsterdam), 1907, 51, 425. See also H. P. Cholmeley, John of Gaddesden and the Rosa medicinae, Oxford, 1912.
