 While some of Wagenseil's later studies may have occurred with "the Sabbatean Behr Perlhefter and Enoch Levi, when they came from Vienna to Fürth around 1670" as mentioned in the preceding passage, by this time Wagenseil already was an accomplished Hebrew/talmud scholar.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.
