This translation by surgeon John Read contains the first printing of John of Arderne's writings on his operation for the cure of anal fistula, written originally about 1376. At one time John of Arderne practiced at Newark-on-Trent; he moved to London in 1370. See the edition by Sir D’Arcy Power, Treatises of fistula in ano, haemorrhoids, and clysters, London, Kegan Paul, 1910. See also No. 5557.
