Prameny k dějinám Židů v Čechách a na Moravě ve středověku Martyrologium or some Hebrew chronicles and charters, were included because they re- late to the Czech Lands events and supplement our other sources. The edition contains records taken from various types of sources, among them charters, whether originals or copies, municipal books, legal and narrative sources, for mulary collections, travelogue reports and inquisition protocols. The evidence of medi- eval sources is complemented by texts from the Bohemian Chronicle (Kronika česká) by Wenceslaus Hájek of Libočany (Václav Hájek z Libočan).3 This chronicle was created in the second quarter of the 16th century (published in 1541) and hence distinctly exceeds the chronological framework of the publication. Moreover, it is a questionable narrative source, whose author handles historical data quite arbitrarily. It is rather a collection of stories than a description of historical facts, which is also true for the portrayal of Jewish history!4 In the end, Hajek’s chronicle has been included for two reasons. The first is the connection to the edition by Bohumil Bondy and František Dvorský, who used Hajek as an important source of information and included a large part of his reports in their regesta edition. However, Bondy and Dvorský did not use Hájek's chronicle systematically. They resorted to it mainly when they could not obtain analogous information from other sources. The second reason to include the texts from Hajek's chronicle is their significance in illustrating changes in the view of Jews and medieval Jewish history that occurred at the beginning of the Modern Period. Hajek of Libočany sometimes, more or less faithfully, drew from historical, mainly narrative sources, but in other places did not hesitate to use modern rhetoric to draw an image of the Jews according to the conceptions of his time. His interpretation interweaves incredible stories and reports on ritual offenses, which according to present-day opinion Jews did not commit. Some of Hajek's reports suggest that he might have drawn from unknown unpreserved sources, which could be recon- structed (for instance Nr. 41). The chronicler was aware also of foreign contacts of the Jewish communities in Bohemia and Moravia. He inserted in his otherwise embellished or entirely fabricated texts believable information on the relations of the Jews with Jews from Regensburg and even Trier (Nr. 11, 14). It seems that Hájek also included biblical stories mixed with historical facts. He hence writes, for instance, that the Jews who came to Prague at Ujezd (Circuit) in the 11th century purchased twelve homes for themselves, perhaps as a direct reference to the twelve tribes of Israel (Nr. 11). It is likely that in these 13) Václav Hájek z Libočan, Kronyka Czeská, Praha: Jan Severin ml. and Ondřej Kubeš ze Žípů, 1541. Recently, the chronicle has finally received its modern full-text edition (LINKA ed. 2013). 14) For the purpose of a clear distinction from the other sources, excerpts from Hájek's chronicle are labeled as such in the heading of each record.
