Entdecktes Judenthum, oder Gründlicher und wahrhaffter Bericht, welchergestalt die verstockte Juden die Hochheilige Dreyeinigkeit, Gott Vater, Sohn und Heiligen Geist erschrecklicher Weise lästern [Judaism Unmasked – a thorough and true report about the horrifying manner in which the stubborn Jews blaspheme the Holy Trinity…], by Johann Andreas Eisenmenger. [Berlin], 1711 (false imprint on title page for: Königsberg). Second edition. Two parts in one volume. German, Hebrew and some Arabic.
Bookplate of Chaim Brody (signed in print "Struck").

Johann Andreas Eisenmenger (1654–1704), a German orientalist and professor of Semitic languages, is considered a precursor of modern antisemitism. Eisenmenger studied the Bible, the Talmud and rabbinical writings and met with Jewish scholars and rabbis, seeking evidence that Judaism was immoral and promoted hatred of Christians. For some 19 years, he professed to be studying the Jewish religion in order to convert to Judaism; in 1694 he even printed the Hebrew Bible in Frankfurt and was granted the approbation of Rabbi David Gruenhut (who described Eisenmenger in his foreword as an "exalted scholar"). Entdecktes Judenthum – "Judaism Unmasked" – is a credible, seemingly scientific study defaming Judaism and its threats to Christianity, and is considered to this day a classic of modern antisemitism. It was dubbed "an encyclopedia of Jew hatred" by historian Simon Dubnow.

This is the second edition, printed clandestinely in violation of an injunction against the book, seven years after the author's death. In order to avoid prosecution, it was falsely presented as having been printed in Königsberg, which was outside the jurisdiction of Emperor Joseph I.
