Aboab, Isaac de Mattathias


ABOAB, ISAAC DE MATTATHIAS (1631–1707), Dutch Sephardi scholar. His father Manuel Dias Henriques (1594–1667) was born in Oporto into a Marrano family, a descendant of Isaac *Aboabii. After escaping from the Inquisition in Mexico he reverted to Judaism as Mattathias Aboab in Amsterdam in 1626. Isaac was a wealthy East India merchant trading with Spain and Portugal under the assumed name of Dennis Jennis. Although not a rabbi, as generally stated, he patronized rabbinical works and was a prolific writer and copyist. His only published work is a brief handbook of moral conduct, first written for his son in Hebrew but published in Portuguese under the title of Doutrina Particular (Amsterdam, 1687, 1691, reprinted by M.B. Amzalak, Lisbon, 1925). He advised his son to read Spanish books from time to time for his entertainment. He also wrote (1685) a morality play (Comedia) on the life of Joseph, and compiled a history and genealogy of his own family.

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.
