We still know less about Walter Hilton than about any other of the great medieval English mystics, yet what we know is enough to show us that in his own age and during the fifteenth century he was more highly esteemed by students and practitioners of the spiritual life than perhaps any devotional writer of the times. Richard Rolle’s sensational works had earned for themselves the immense popularity which they deserved, but there were many who came to deplore this popularity, and it is evident that the influence of Hilton was regarded as both a salutary corrective to Rolle’s extremes, and as in itself beneficial. In the present century this development of later medieval thought has been again obscured, partly, though quite involuntarily, because of the new impetus to the study of Rolle given by Miss Hope Emily Allen, in her immensely scholarly if labyrinthine Writing Ascribed to Richard Rolle, and in her admirable little edition, English Writings of Richard Rolle. In this second work, published in 1931, she presented one solution to the problem which confronts everyone who wishes to edit a text which achieved a large circulation in the Middle Ages. Had she attempted a complete collation of all the surviving manuscripts (no less than ninety-three separate texts of the various English writings which she edited were known to her), she might well have been still engaged in the task. Instead, she took for each treatise or poem two or three of what she considered to be the best manuscripts; and so for the last twenty-four years we have been able to read good, early versions of Rolle’s own words largely free from the welter of footnotes with which most of those who are engaged in such scholarly pursuits still encumber their works.
