Jonah ben Jiṣhaq, Jehudah


Learned Jewish convert; b. Safed, Galilee, Oct. 28, 1588; d. Rome, May 26, 1668. During his extensive travels in Europe as a rabbi he was converted to Catholicism in Poland and took the name of John the Baptist. Later he was sent by the King of Poland to Constantinople for the purchase of precious stones. There, however, he was arrested on the charge of espionage and would have been executed had not the Venetian ambassador interceded for him and enabled him to go to Italy. In Italy, where he was known as Giovanni Battista, he taught Hebrew and Aramaic, first at Pisa and then at the College of the Propaganda, Rome. One of his students at Rome was G. bartolocci (161387), who received much help from Jonah in preparing his masterpiece, the Bibliotheca magna rabbinica de scriptoribus et de scriptis hebraicis (4 v. Rome 167594). Jonah himself published a Hebrew translation from the Latin of the four Gospels, with a preface by Pope Clement IX (Rome 1668).

Learn more about citation styles

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
