Professor Fernand Mosse of the Coll?ge de France is at home in all the Germanic languages and literatures, but for many years he has paid particular attention to English. Since he is a medievalist he has interested himself first and foremost in the earlier periods, and since he is a teacher as well as investigator he has been long concerned to smooth the path of students taking their first steps into a field far from our day and time. A few years ago, this concern of his ripened into a work that won general recognition as soon as it came out: his Manuel de l'Anglais du Moyen Age des Origines an XIVe Si?cle. In the Manuel the author's mastery of the material and talent for clear and orderly presentation are happily combined. In this work we have by far the best introduction to medieval English now available.-from the Foreword
