In this dissertation, I examine the various ways in which medieval authors used the term "lollard" to mean something other than "Wycliffite." In the case of William Langland's Piers Plowman, I trace the usage of the lollard-trope through the C-text and link it to Langland's dependence on the Parable of the Wheat and the Tares. Regarding Chaucer's Parson's Tale, I establish the orthodoxy of the tale's speaker by comparing his tale to contemporaneous texts of varying orthodoxy, and I link the Parson's being referred to as a "lollard" to the eschatological message of his tale. In the chapter on The Book of Margery Kempe, I examine that the overemphasis on Margery's potential Wycliffism causes everyone in The Book to overlook her heretical views on universal salvation. Finally, in comparing some of John Lydgate's minor poems with the macaronic sermons of Oxford, MS Bodley 649, I establish the orthodox character of late-medieval English anti-Wycliffism that these disparate works share. In all, this dissertation points up the eschatological character of the lollard-trope and looks at the various ends to which medieval authors deployed it.
