John Bale was an English churchman, historian and controversialist, and Bishop of Ossory in Ireland. He wrote the oldest known historical verse drama in English, and developed and published a very extensive list of the works of British authors down to his own time, just as the monastic libraries were being dispersed. His contention that Joseph of Arimathea had brought a proto-Protestant faith to Britain that was purer than Catholicism was to have far-reaching ramifications; but his unhappy disposition and habit of quarrelling earned him the nickname "bilious Bale".

John Wycliffe was an English scholastic philosopher, theologian, purported biblical translator, reformer, Catholic priest, and a seminary professor at the University of Oxford. He became an influential dissident within the Catholic priesthood during the 14th century and is considered an important predecessor to Protestantism. Wycliffe questioned the privileged status of the clergy, who had bolstered their powerful role in England, and advocated radical poverty of the clergy.
