מתי נוסד הדפוס העברי הראשון בקרקוב?

This research note argues that the first Hebrew book printed in Kraków was Sha’arei Dura by Rabbi Isaac ben Meir Dueren, which appeared in 1534, and not other commonly-cited candidates, including a 1530 edition of the Pentateuch that is no longer extant, a volume of a legal code often misattributed to the same year, and a Passover hagadah mistakenly believed to have appeared in 1531. In the Ossolineum Library in Wrocław there is a book of Hebrew penitential prayers for the High Holidays bearing a 1532 imprint and a scene from
Kraków on the title page. However, because the words ‘Jesus Christ, King of the Jews,’ appear in Hebrew on a page of the book, it is unlikely that this volume was published before 1537, when the presumed publishers, the brothers Helicz, converted to Christianity.
