THE history of mediæval medicine, says Prof. E. Nicaise, ["La grande chirurgie de Guy de Chauliac." Paris, 1890, pp. x-xv.] has been divided into four great epochs. The first, lasting from the fifth to the eleventh century, was remarkable for the Arabian school of medicine. The second period embraced the eleventh and twelfth centuries, and witnessed the rise of the schola Salernitana: it was the time of the Crusades and of that intermingling of the East and West from which sprang the marvellous work of the twelfth and thirteenth centuries. The work of the third period was all too short, and was brought to a sudden close by the Black Death which ravaged the world in 1348-9. It is properly described as the beginning of the modern era, the pre-Renaissance. A mere list of the Universities established will give some idea of the intellectual activity of the time. Montpellier (1137); Paris (1176); Oxford (1200); Cambridge (1209); Padua (1222); Naples (1224); Salamanca (1230); Toulouse (1230); Orléans (1231); Valladolid (1250); Seville (1254); Coimbra-Lisbon (1290); Lerida (1300); Avignon (1303); Rome (1303); Grenoble (1332); Angers (1337); Pisa (1343); Prague (1347); Florence (1349); Perpignan (1349); Huesca (1359); Cracovia (1364); Pavia (1365); Orange (1365); Vienna (1365); Erfurt (1379); Heidelberg (1385); Cologne (1388); Buda (1389). [The dates appended to the Universities are merely intended to show when each was known to be actually in existence—a few were created, the majority developed from small beginnings.] The fourth period was retrograde. Wars abroad and economic troubles at home seemed to have crushed the spirit of the few survivors from the previous generation.
John Arderne belongs to the thirteenth century in spirit and in thought, although the accident of birth placed him in the next generation. He was well educated, and he reflects the current ideas of his time just as every well-educated surgeon at the present day is an epitome of his surroundings. Nothing is known of his history except for the autobiographical details given in the various manuscripts of his works and a small body of floating tradition which has been handed down through the centuries.
