This study examines the life and death of the Franciscan preacher and reformer, St John of Capistran (1386-1456). Based on a reconstruction of the available sources, the author explores the collections of the miraculous deeds of St John Capistran which were recorded at his burial place in Ilok (a city located on the periphery of western Christianity in Croatia), and analyzes them from four points of view: a philological evaluation of the collections; a typology of the miracles he performed; an outlook of the so-called observant reform in the Franciscan order, and of Capistran"s place within it; and the miracles as a phenomenon of religious experience.
