The lost morality, the Paternoster Play, has been a subject for speculation among many writers upon early English drama. Although no finding can lay claim to the last word upon the question, each additional bit of evidence helps toward a more accurate definition of the play. It is the purpose of this paper to call attention to the possible relation of this play to sermons upon the Oratio Domini among the treatises of Hugo of Saint Victor. Before embarking upon this discussion, it seems desirable to summarize briefly the facts and theories concerning the play now current. The material is of two sorts: information in regard to the morality to be derived from documents contemporaneous with it, and speculations as to its origin and nature which have been put forward by various scholars.
