The present collection, divided into three thematic sections, includes twenty-one studies on the history of the University of Prague from its foundation in 1348 to the 16th century. The first section is devoted to the birth of the university, its first institutions, the growth of the earliest colleges and the victory of the Reformist party. The second part concentrates on the curriculum, examinations, graduations and annual disputations of the Faculty of Liberal Arts. Section three deals with university polemics about universalia realia, mainly in relation to the scholarly and literary activity of Jerome of Prague (+ 1416).
