The fourteenth and fifteenth centuries were times of tumultuous change in medieval Europe; they witnessed the Black Death, the Great Papal Schism, heightened fears of the apocalypse, and the elimination of Spains non-Christian population. Few figures were as widely and as intimately involved in late medieval Europes struggles as Saint Vincent Ferrer. Perhaps the foremost preacher of his day, Ferrer spent the final two decades of his life traversing Europe, preparing the world for its imminent destruction. Saint Vincent Ferrer (d. 1419), His World and Life reassesses the controversial preachers motives, methods, and impact, tracing Ferrers journey from obscure logician to angel of the apocalypse, as he came to be known. At the same time, the book offers new insights into the depth and breadth of late medieval apocalyptic anticipation, and into the processes that ultimately led to the expulsions of Spains Jews and Muslims.
