A vague suggestion has been in the air of late that there is a more than casual similarity between the so-called Ludus Coventriae and the plays of the Digby Manuscript. The following paper is an attempt to render that suggestion somewhat more concrete and to define the nature of that relation. First, however, it is clearly necessary to deal with the questions of the structure and development of the Ludus Coventriae before its external relations may be considered. Miss Swenson's recent careful study is perhaps most valuable in its metrical analysis; but even this must be tested in the light of Miss Block's somewhat more fruitful examination of the manuscript, which in turn neglects the metrical form of the plays. Miss Swenson is led to believe that the “tumbling” lines mark the chief additions to the cycle; but the changes noted by Miss Block which are indicated by manuscript disturbance go far beyond these in certain respects. We are justified, therefore, in using the evidence from both sources as a basis for a new study, with the hope that further and more specific conclusions may be reached.
