The principal source of the plays belonging to this common kernel is, of course, the biblical narrative, which is followed, so far as it goes, with considerable fidelity, the most remarkable divergence being that of the _Ludus Coventriae_, which merges the Last Supper with the scene in the House of Simon. But certain embroideries upon scripture, which found their way into the religious drama at an early stage of its evolution, are preserved and further elaborated. Thus each of the four cycles has its Harrowing of Hell, which links the later scenes with the earlier by introducing, as well as the devils, such personages as Adam and Eve, Enoch and Elijah, John the Baptist and others[375]. Similarly the Suspicion of Joseph and the _obstetrices_ at the Virgin Birth finds a place in all four[376], as does the Healing of Longinus, the blind knight, by the blood-drops from the cross[377]. Other apocryphal or legendary elements are confined to one or more of the cycles[378]. The Chester plays, for example, have a marked development of the eschatological scenes. Not only is the _Iudicium_ itself extremely long and elaborate, but it is preceded by two distinct plays, one a section of the split-up _Prophetae_ ending with the Fifteen Signs, the other an Antichrist, in which, as in the Tegernsee _Antichristus_[379], Enoch and Elijah appear as disputants. The most legendary of the northerly cycles is without doubt the _Ludus Coventriae_. It has the legend of Veronica, which is only hinted at in the corresponding York play. And it has so long a series of scenes drawn from the legends of the Virgin as to make it probable that, like the Lincoln plays and another East Midland cycle of which a fragment is extant, it was performed not on Corpus Christi day but on that of St. Anne. Before the Annunciation it inserts the episodes of Joachim and Anne, Mary in the Temple, and the Betrothal of Mary. To the common episode of the Suspicion of Joseph it adds the Purgation of Mary. In the Resurrection scene is a purely legendary Apparition of Christ to the Virgin; while the Death, Burial, Assumption, and Coronation of Mary intervene between the Pentecost and the _Iudicium_. This matter from the after-history of the Virgin belongs also to the York plays, which add the Apparition to St. Thomas of India.
