Jack Upland or Jack up Lande (ca. 1389-96?) is a polemical, probably Lollard, literary work which can be seen as a "sequel" to Piers Plowman, with Antichrist attacking Christians through corrupt confession. Jack asks a "flattering friar" (cf. Piers Plowman's "Friar Flatterer") nearly seventy questions attacking the mendicant orders and exposing their distance from scriptural truth.
