@ARTICLE{Zuzek_Tomasz_On_2016, author={Zuzek, Tomasz}, volume={tom 33}, journal={Pamiętnik Biblioteki Kórnickiej}, pages={143-149}, howpublished={online}, year={2016}, abstract={The discovery of a seventeenth-century duplicate copy of two letters (one written by Cardinal Zbigniew Oleśnicki to John of Capistrano on 15.04.1452, and the latter’s reply to the Cardinal and King Casimir Jagiellonian) on sheet 191 of the manuscript marked Chigi Q II 51 kept in the Vatican Apostolic Library, made it possible to determine the previously unknown provenance of the manuscript marked 1399 I from the Princes Czartoryski Library. As a result of an analysis of the content and the layout of the duplicate copy, it was established that the text from sheet 191 was copied directly from the manuscript kept in the Princes Czartoryski Library. The Chigi manuscript contains information on the source of the duplicate: a manuscript kept in St. Anne’s Franciscan friars monastery in Warsaw. Therefore, the monastery should be recognised as the place in which the Princes Czartoryski Library manuscript marked 1399 I was kept in the 17th century. It ended up there in the second half of the 15th century, soon after the monastery was founded, and was most probably kept there as long as until the beginning of the 19th century, when it was purchased by Tadeusz Czacki.}, type={Artykuły / Articles}, title={On the provenance of manuscript No. 1399 I from the Princes Czartoryski Library in Krakow}, URL={http://www.czasopisma.pan.pl/Content/113424/PDF/Zuzek.pdf}, }
