The manuscript is now housed in the British Library, London (BL MS Cotton Vespasian D.8). As its name might suggest, though, it was once the property of the 17th-century antiquarian Sir Robert Bruce Cotton and was housed in his large library. Cotton's librarian, Richard James, quickly examined the manuscript and erroneously assumed that it contained the Biblical plays performed in Coventry during the 15th and 16th centuries, thus naming them the Ludus Coventriae or "the Play Called Corpus Christi". He was mistaken in both cases, but that mistake has proven very difficult to correct; the name Ludus Coventriae persists in the secondary and critical literature well into the 20th century. A further complication of the N-Town plays was made by Hardin Craig who, in his "Medieval Drama" (1955), called the collection the Hegge Plays after their former owner, Robert Hegge. The name Hegge Plays only briefly caught on, and the most common way to refer to these plays now is The N-Town Plays, after the reference in the last stanza of the opening proclamation that the play was to be played at "N-Town"; when the plays toured from town to town, N. (meaning nomen, the Latin for name) would be replaced by the name of the town the cycle was playing in at any given time.
