John Bale John Bale (21 November 1495 – November 1563) was an English churchman, historian and controversialist, and Bishop of Ossory. He wrote the oldest known historical verse drama in English (on the subject of King John), 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 unhappy disposition and habit of quarreling earned him the nickname "bilious Bale".
