Dutch controversialist of the seventeenth century. He was the author of "Libri VIII pro Convincendis et Convertendis Judæis," a manual for missionaries to the Jews, with copious prolegomena (Leyden-Amsterdam, 1655). Although he was apparently in sympathy with the Jews, his real purpose was to attack their religion. These eight books, without the prolegomena, had already appeared under the title "Disputationes Anti-Judaicæ" (Utrecht, 1645). He also wrote "Summa Controversiarum Religionis cum Infidelibus," a manual for missionaries to the heathen (Frankfort-on-the-Main, 1697).
