The study sheds new light on the genesis of the 45 articles of John Wyclif condemned by the University of Prague in 1403. Based on the study of the manuscripts, the author draws attention to the hitherto unknown redaction of the articles. By its analysis, he proves that the Prague master Johannes Hübner did not select some of the condemned propositions directly from Wyclif’s books, as was previously thought, but took them from this neglected redaction. The author traces its origins against the background of Wyclif’s English ecclesiastical prosecution, and also examines its reception in Bohemia. The study includes a list of the manuscripts of 45 articles and their three redactions, two of which the author critically publishes in print for the first time in an appendix.
