By the later fourteenth century, it has been assumed that Gnosticism and its influences dispersed almost completely. While the late-medieval church was vigorous in its efforts to teach orthodoxy to the laity, Natanela Elias reveals here that gnosticism actually simmered below the surface in a number of late-medieval texts. The first of its kind, this study examines this spiritual undercurrent in late medieval English literary works and sheds new light.
