Johann Christoph Wagenseil

Indeed, in "Die Letzte Vertreibung der Juden aus Wien und Niederösterreich" Kaufmann expands on the subject of how Wagenseil, while still aged in his early 20s stayed for extended periods in the Vienna Jewish community where in particular he befriended and studied under Dr. Jehuda Löb Winkler as well as Rabbi Model Oettingen, thereafter maintaining correspondence with both of them from all the locations and university cities where he later resided as preceptor of the Kaiser's sons, as well as throughout ensuing years.

][2] Wagenseil devoted his learning to publishing anti-Christian works of Jewish authors and undertook long journeys to gather his material and conduct research.

The fruit of Wagenseil's travels was the collection Tela Ignea Satanæ, sive Arcani et Horribiles Judæorum Adversus Christum, Deum, et Christianam Religionem Libri (Altdorf, 1681), which included the apologetic Ḥizzuḳ Emunah of the Karaite Isaac Troki.

Wagenseil wrote, besides the above-mentioned books, Hoffnung der Erlösung Israels (Leipzig, 1705), which appeared in a second edition (Altdorf, 1707), augmented by a number of smaller works under the general title Benachrichtigungen Wegen Einiger die Gemeine Jüdischheit Betreffenden Sachen.

His Latin history of Nuremberg De civitate noribergensi commentatio (Altdorf, 1697) included the German appendix Buch von der Meister-Singer holdseligen Kunst Anfang, Fortübung, Nutzbarkeiten, und Lehrsätzen (dated 1680), which discussed the origin of the guild, their Tabulaturen and customs.
