 He died in Altdorf in 1705.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.Becoming convinced by the "Toledot Yeshu" that the Jews were guilty of blaspheming Jesus, Wagenseil addressed to all high potentates his "Denunciatio Christiana de Blasphemiis Judæorum in Jesum Christum" (Altdorf, 1703), in which he implored them to restrain the Jews from mocking Jesus, Mary, the cross, the mass, and Christian teachings.
