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. [Frankfurt am Main], 1700. Two volumes. German.
Eisenmenger (1654-1704) – a German orientalist and professor of semitic languages, is considered one of the messengers of anti-semitism in the new era. This book was named by the writer and historian Shimon Dubnov "The Encyclopedia of the Hatred of Jews". Eisenmenger mastered the Bible, Talmud and rabbinical writings and encountered Jewish sages and rabbis, in order to retrieve references against the Christian faith. For 19 years he presented himself as a person trying to approach Judaism and study its sources in order to eventually convert; in 1694 he printed the Bible in Frankfurt and was granted the approbation of Rabbi David Gruenhut who mentioned him in the introduction as an "exalted scholar". The book is an extensive study written in an apparently reliable scientific manner against Judaism and its dangers to Christianity and is considered a basic book of Modern Anti-Semitism to the present day.
