Entdecktes Judenthum, oder, Gründlicher und wahrhaffter Bericht, welchergestalt die verstockte Juden die Hochheilige Dreyeinigkeit, Gott Vater. erschrecklicher Weise lästern [Judaism Unmasked – a thorough and real report about the horrifying manner in which the stubborn Jews slander the Holy Trinity and disgrace it], by Johann Andreas Eisenmenger. [Berlin], 1742. Two parts bound together. German and some Hebrew.
Eisenmenger (1654-1704) – a German orientalist and professor of Semitic languages, considered one of the first bearers of anti-Semitism in the new era. This book was dubbed by writer and historian Shimon Dubnov the "Encyclopedia of the Hatred of Jews". Eisenmenger mastered the Bible, Talmud and rabbinical writings and met with Jewish sages and rabbis, seeking to retrieve references against the Christian faith. For 19 years he presented himself as a person meaning to approach Judaism and study its sources in order to eventually convert; in 1694 he even printed the Hebrew Bible in Frankfurt and was granted the approbation of Rabbi David Gruenhut, who mentioned him in the introduction as an "exalted scholar". The book "Entdecktes Judenthum" – "Judaism Unmasked" – is an extensive study, written in an apparently reliable scientific manner, against Judaism and its dangers to Christianity, and is considered to this day a classic of modern anti-Semitism.
