William Langland is one of the most important authors of the middle ages and Piers Plowman, one of the most challenging and complex poems of all time. Written and revised in the last decades of the fourteenth century, Piers Plowman is a dream vision which gives an account of one mans ardent quest for personal salvation in a world torn apart by social unrest and economic upheaval. Langlands passionate concern with issues such as social injustice, the use and abuse of learning, church corruption and poverty ensured his poems wide and immediate following. It also gained Piers Plowman a later literary reputation for political and religious radicalism which far outstripped the poems sentiments at the time of its writing. Taking into account recent critical and historical work on the poem, this study looks at new ways of exploring the poems complex allegorical form and argues for the text to be read as a far-reaching critique of the social and sacred models that were the foundation of Langlands world.
