The plays just enumerated may be regarded as of precyclical types. But there are a few others which, although they occur independently, would have their more natural position in cycles of less or greater range. In some of these cases it is probable that the independence is only apparent, a mere matter of incomplete evidence. There are two fifteenth-century plays, both on the subject of Abraham and Isaac, one of which is preserved in the ‘Book of Brome’ from Suffolk, the other in a manuscript now at Dublin, but probably of South Midland _provenance_. It is of course not impossible that these represent isolated performances, but it is on the whole more likely that they are fragments of lost cycles. A third play, of Midland origin, preserved in the Digby manuscript, occupies an exceptional position. It deals with the Massacre of the Innocents and the Purification, and allusions in a prologue and epilogue make it clear that it belonged to a cycle in which it was preceded by a _Pastores_ and a _Magi_, and followed by a Christ in the Temple. This cycle, however, was not played all at once, but a portion was given year by year on St. Anne’s day. One of the groups of plays brought together in the _Ludus Coventriae_ was evidently intended for performance under similar conditions. It is probable that the _ludus Filiorum Israelis_ of the Cambridge Corpus Christi guild about 1350, the Abraham and Isaac of the ‘schaft’ of St. Dunstan’s, Canterbury, between 1491 and 1520, and the Adam and Eve (1507) and ‘Cayme’s pageaunt’ (1512-5) of St. Lawrence’s, Reading, formed parts of Corpus Christi cycles given in those towns.
