The true nature of the manuscript has been hidden by the fact that the scribe arranged all the episodes in "chronological order" starting with Creation and ending with Judgment, simulating an episodic play presenting salvation history as in the two northern civic cycles from York and Chester. As he did this he buried the Mary Play inside the Nativity sequence and copied the Passion Play into place between the Raising of Lazarus and the Resurrection appearances. It has taken painstaking paleographic and codicologic examinations of the manuscript to determine what the scribe actually did. To further complicate the matter, at some point in the history of copying out these plays, the proclamation was attached to them. Although the proclamation does not match the plays that follow, someone, possibly the scribe of this manuscript, placed numbers in the margin of the text against incidents that correspond to the description of the "pageants" in the proclamation. This does not affect the single episode pageants but it breaks up the flow of the Passion Play and has obscured the very existence of the Mary Play for centuries.
