Among the questions which still await investigation in the literary history of sixteenth and seventeenth century England, not the least important is that of the survival of the vernacular writings of the Middle Ages. No one can have studied the records of publishing activities during the Tudor and Stuart periods without becoming aware that a considerable number of the romances, tales, poems, chronicles, lives of saints of the fourteenth and fifteenth centuries still continued to circulate, and to find, though probably in ever smaller numbers, appreciative readers. Nor can anyone who has noted this persistence of medieval literature beyond the Middle Ages fail to draw from it inferences not a little damaging to our current conceptions of sixteenth and seventeenth century taste. As yet, however, no historian of literature has dealt with the problem in a systematic or detailed way—no one has tried to set clearly before us precisely which works, out of the total body of medieval writings, remained in vogue, how long the popularity of each of them lasted, how far they were modified in form or content to suit the taste of successive generations, by what sort of “public” they were read, and of what nature was the influence which they exercised upon the newer writers. Some day perhaps we shall have such a history of the survival of medieval literature in early modern England. In the meantime, as a preliminary treatment of a single phase of the subject, the present study of Guy of Warwick may not be without its interest. It proposes to trace from the days of the early printers to the close of the eighteenth century the fortunes of but one—though perhaps the most typical one—of the many romances whose popularity survived the Middle Ages.
