The chief difficulty in tracing the origin of the secular drama in Germany is the lack of texts to prove the performance of other than religious plays. Nevertheless a sufficient number of secular texts have been brought to light to contradict the old belief that expansion of the comic scenes in the religious dramas resulted in the early Carnival play. M. J. Rudwin, in his notable study, proved the Carnival play to have been “the natural outgrowth of the Carnival customs themselves.” Modern historians of literature agree with him on this point but discuss the development of the Fastnachtspiel in Nuremberg no further than to declare its origin to have been in the most important masque of the time, the Schembartlauf. Yet in the recent special work on the history of the German drama, Das deutsche Drama, F. Michael disclaims any immediate connection between the Schembartlauf and the plays. Up to the present no detailed examination of the manuscripts in which the Schembartlauf was recorded, the so-called Schembartbücher, has appeared. It will be of advantage to study the actual content of the manuscripts in order to estimate their importance for the history of German literature. Conclusions may then be drawn as to the possible relation of the Schembartlauf to the Fastnachtspiele.
