• Piers Plowman: - Piers Plowman, in full The Vision of Piers Plowman, Middle English alliterative poem presumed to have been written by William Langland. • Three versions of Piers Plowman are extant: - the poem’s short early form, dating from the 1360s; - a major revision and extension of A made in the late 1370s; and - a less “literary” version of B dating from the 1380s and apparently intended to focus the work’s doctrinal issues. - Some scholars think that version C may not be entirely attributable to Langland.
