CHAPTER II.

LEPROSY IN MEDIEVAL BRITAIN. The history of leprosy in Britain can hardly be the history of leprosy alone, but of that disease along with others which were either mistaken for it or conveniently and euphemistically included under it. That there was leprosy in the country is undoubted; but it is just as certain that there was _lues venerea_; that the latter as a primary lesion led an anonymous existence or was called _lepra_ or _morphaea_ if it were called anything; that the remote effects of the lues were not known as such, being taken for detached or original outcomes of the disordered humours and therefore in the same general class as leprous manifestations; and that the popular and clerical notions of leprosy were too superstitious and inexact, even if the diagnostic intention had been more resolute than it was, to permit of any clear separation of the leprous from the syphilitic, to say nothing of their separation from the poor victims of lupus and cancer of the face, of scrofulous running sores, or of neglected skin-eruptions more repulsive to the eye than serious in their nature. I shall give some proof of each of those assertions--as an essential preliminary to any correct handling of the historical records of British leprosy. Leprosy in Medieval Medical Treatises. The picture given of true leprosy in the medieval treatises on medicine is unmistakeable. There are two systematic writers about the year 1300 who have left a better account of it than the Arabian authors from whom they mostly copied. While the writers in question have transferred whole chapters unaltered from Avicenna, Rhazes and Theodoric, they have improved upon their models in the stock chapter ‘De Lepra.’ It so happens that those two writers, Bernard Gordonio and Gilbertus Anglicus, bear names which have been taken to indicate British nationality, and the picture of leprosy by the latter has actually been adduced as a contemporary account of the disease observed in England[134]. Gordonio was a professor at Montpellier, and his experience and scholarship are purely foreign. The circumstances of Gilbert the Englishman are not so well known; but it is tolerably certain that he was not, as often assumed, the Gilbert Langley, Gilbert de l’Aigle, or Gilbertus de Aquila, who was physician to Hubert, archbishop of Canterbury († 13 July, 1205)[135], having been a pupil at Salerno in the time of Aegidius of Corbeil (about 1180). The treatise of Gilbertus Anglicus bears internal evidence of a later century and school; it is distinguished by method and comprehensiveness, and is almost exactly on the lines of the _Lilium Medicinae_ by Gordonio, whose date at Montpellier is known with some exactness to have been from 1285 to about
