A new issue of the journal Judaica Bohemiae (47/2012, 2) came out at the end of December 2012. This volume includes a study by Marie Buňatová on commercial relations between the Jews of Prague and Krakow in the period before the Battle of White Mountain. On the basis of a thorough analysis of sources from Czech and Polish archives, this study uncovers the operation, form and development of Bohemian-Polish trade in the 16th century, as well as the key role played therein by Jews. Ivo Cerman’s paper deals with the almost forgotten work Jüdischer Blut-Eckel (1753) by Alois von Sonnenfels – a Jewish convert and father of the famous representative of the Austrian Enlightenment, Joseph von Sonnenfels – which was written in defence of Jews for the purpose of disproving allegations that they used Christian blood. In the Documents section, Alexandr Putík presents and analyzes in detail a new source relating to the trial of Yom-Tov Lipmann Heller from 1629–1630, and Jitka Korbelová provides information about the so-called Schulfassionen – an important, hitherto little-explored source relating to the history of Jewish education in Moravia. The Reports section contains an article by Jaroslav Kuntoš about the unique archaeological find of a medieval signet ring with a Hebrew inscription, which was uncovered in Prague’s Republic Square (náměstí Republiky) eight years ago. Dana Veselská provides information about a project focused on identifying the donors of objects in the collections of the Jewish Museum In Prague, Pavel Sládek reports on the first year in existence of the Prague Centre for Jewish Studies, and Arno Pařík covers a recent exhibition on the early work of Georges Kars, which was held at the museum’s Robert Gutmann Gallery. The volume also includes reviews of Pavla Damohorská’s The Jewish Prayer for the Welfare of the Country as the Echo of Political and Historical Changes in Central Europe (2010, reviewed by Meir M. Bar-Asher), Pavel Sládek’s Raši (1040–1105). Vznik biblického komentáře ve frankoporýnských židovských centrech [Rashi (1040–1105) and the Origins of Biblical Commentary in the Franco-Rhenish Jewish Centers] (2012, reviewed by Marcela Zoufalá) and Georg Gaugusch’s Wer einmal war. Das jüdische Grossbürgertum Wiens 1800–1938. A–K (2011, reviewed by P. Kocman).
