The Cambridge History of English and American Literature in 18 Volumes (1907–21). Volume II. The End of the Middle Ages. I. “Piers the Plowman” and its Sequence. § 2. Form of the Poems.   Before taking up any of the problems just suggested, we may recall briefly certain undisputed facts as to the form of the poems. They are written throughout in alliterative verse of the same general type as that of Beowulf and other Old English poems, and, at first sight, seem to form one long poem, extant in versions differing somewhat from one another. As Skeat has conclusively shown in his monumental editions of the texts, there are three principal versions or texts, which he designates the A-text, the B-text and the C-text, or the Vernon, the Crowley and the Whitaker versions respectively. The A-text, or Vernon version, consists of three visions supposed to come to the author while sleeping beside a stream among the Malvern hills. The first of these, occupying the prologue and passus I–IV, is the vision of the field full of folk—a symbol of the world—and Holy Church and Lady Meed; the second, occupying passus V–VIII, is the vision of Piers the Plowman and the crowd of penitents whom he leads in search of Saint Truth; the third, occupying passus IX–XII, is a vision in which the dreamer goes in search of Do-well, Do-better and Do-best, but is attacked by hunger and fever and dies ere his quest is accomplished. The B-text and the C-text are successive modifications and expansions of the A-text.   2
