This is a study of the Wycliffite heresy, otherwise known as Lollardy, which flourished in England in the late fourteenth and early fifteenth centuries. Kantik Ghosh examines major texts by John Wyclif, William Woodford, Nicolas Love, Thomas Netter as well as the anonymous authors of the English Wycliffite Sermons, along with a wide range of scholastic, homiletic and meditative texts in Latin and English. Whatever the ultimate fate of Lollardy as a religious movement, he reveals that the debates it initiated successfully changed the intellectual landscape of England.
