The Chronica fratrum Minorum de Observantia provinciae Bohemiae secularibus non communicanda is the second Bohemian Observant Franciscan chronicle published in this series. The initial section, spanning the years 1440–1553, provides a comprehensive overview of the history of the Franciscan Observant Order during this period. It is an invaluable narrative source for the Bohemian province, and furthermore a critical source for the history of the Cismontane family of the Observant friars. The text has not been edited thus far and consequently evaded the attention of historians; the Chronica constitutes a fundamental addition to the known narrative sources. In this respect the present text serves to complement the other crucial Franciscan Observant chronicles by John of Komorowo and Nicholas Glassberger. This newly accessible chronicle enhances the source pool of the self-presentation through history-writing of mendicant Orders in general.
